I took this interesting photo of the build up of lime dust on my bucket from Cabin Fever. I guess I moved about 4cy that weekend. I forgot to pickup on the bucket with my hand to see what a full bucket weighed with that wet stuff. I assume it was in the neighborhood of 13-14lbs.
That material was very wet deep inside the pile.

Sure was fun digging on "the pile" with somewhat of an active mine diorama we had going! I can't wait to do some more digging in May at the Lakeside Sand and Gravel open house and the Brownsville,PA show. Lakeside is real easy digging in a pile of coarse sand. The only problem there is; I have to set on a piece of plywood on that soft sand and I need to dodge a kid or two throwing sand at my model since it's next to the kiddy play area.
We finally weighed the 9W when we unloaded it from my trailer and I was pretty close estimating 175lbs. and it is exactly 180lbs. I figure about 25-30 more pounds of parts and she'll be complete.

Found a good deal on some brass sheet today. I wish I had bought all of my brass 6-7yrs ago. This stuff has gone thru the roof in past couple years. I think there's close to $800 in the boom alone and could have been at least half of that if bought sooner. I'll be working on the outer skin around the revolving frame soon. Lots of rivets to install.

Is the structure of the house steel? If it is, how do you keep it from rusting? Heated shop? Around here it's so wet unprotected steel doesn't take long before rust starts to form.

All steel. I'm fortunate to be able to keep it in my heated shop. It does get some rust now and then. I make sure to mist it down with WD-40 once and a while. I haven't decided to paint the steel or use tool black to blacken some of the parts. The interior may get painted green and battleship gray. I'm going to experiment with green patina on the house sheet metal since the 1:1 I'm modeling was green with black boom and frame. I'm hoping the black patina on the boom and frame will have some brownish look to it so it will look old rusted and weathered. The boom is already darkening on it's own after a year of use.

Agree about the brass prices, tried to locate some profiles, the manufactor wanted top $$. Guess it will never be much cheaper, chineses buys all they can.
Have started to stock up all material I need for coming models, always nice to have a supply at home!

$800 in the boom, and a lot of work to remove the better part of it, guess you have $600 milled off!
Dan

Your right about milling away a few dollars of metal Dan.
A lot of the store bought small profiles are just milled solid bar. I have other larger brass extrusions that I own the the die with my design but the mill will not produce the tiny thin walled extrusions any more. Way back when I was designing the "A" frame, I inquired about having one of the model brass suppliers sell me some 3/4'' "I" beams. They told me that they would mill them for me. Well since I have a milling machine, I just made my own and went with steel for strength. It is a very time consuming process. Set up in one to three vices on the table depending on the length,I milled one side then turned it over for the other. One big problem with milling one side is there's a lot of surface tension and the piece will bow considerably so I needed to make sure I hammered the part down flat in the vice on the long parallel. After the second side the beam flattened it's self out pretty well. Brass not so well but straightening it was easy. All in all, I think they took me about 2hrs per foot and wore out a few 5/8'' roughing endmills

No progress right now Tom. I haven't been down East yet to get the measurements of the house and walking bearing supports. Hope to get there by May.
The walkway is another measurement needed and If I'm allowed to climb, I need the deflection sheave framing up near the top of the boom.

Well, It's been 4 months since I did anything on the dragline and still haven't due to being busy with regular work and side jobs. But, I loaded it up or shall I say; walked it into my trailer this evening so I can take it down to Brownsville,PA to dig into some dirt at the show this weekend.
I can't wait to try some new techniques I've learned from reading and watching 1:1 draglines operating. I'll be trying out a new to me, Power Conditioner or Line Conditioner purchased from Evil Bay. This device is supposed to give me a clean regulated 115vac. Hopefully it will take care of any bad power line conditions like we encountered at the Cabin Fever Expo when my machine wouldn't work at all till the power in the building was fixed. I'll be taking an extra hoist cable encase the existing one fails. I noticed alot of areas where the wires are coming undone. It is the original hoist rope with approx. 15days of steady 8-10hrs digging on it. I wonder what the life expectancy of the 1:1 ropes are in similar conditions.
I'll also be trying the Tournarocker in real dirt for the first time. I had it out at the; ECMT meet in Brookville,PA and it did OK but I'm sure the one drive will quit working when a set screw backs out again. Just another small project that needs addressed in the driveline.

Not yet Tom. I still haven't been down East to get the measurements and kinda busy at work. The machine work flawlessly once I changed a jumper in the swing motor drive. Since the beginning, I had it set for "regenerate to stop" It always seemed to work very well until a slight adjustment change on the current limit and start/stop timing. I had one direction set perfectly but the other way it would glitch and jerk . Also I had the trim on the TX set one way some to keep the drive electrically centered.
Now while swinging either direction It's working smooth but it takes some practice to go from full speed to where you want to stop in a precise point,especially when the machine is not leveled very well as in my pictures. I had some trouble keeping it from sinking in the soft dirt I piled up first. Later I coated the top of the pile with some damper dirt to pack.

Looks like you had about a ton of fun ;)
I would say that pile weighed at least a Ton :D

As a matter a fact, I was at the 1:1 machine "Jack" yesterday finally, and took about a hundred more pictures of details and several measurements. It was windy and it was a real pain trying to send the tape measure down the side to my helper hold on to paper and keep from dropping my camera. I climbed half way up the "A" frame to get some much needed measurements of the bolts and plates on the diagonal bracing. I didn't have the guts to go all the way up the "A" frame and definitely not up the boom walkway due to the wind.

I don't think he'll be scrapped. They recently bought some parts from a diesel 9W that was scrapped and I'm assuming when the time comes the necessary work will be done . There's not many 9W's left as far as I can tell.
I didn't look up inside to assess the internal damage. I do know the frame work is built up just like the exterior's riveted angle plate design. From what I can tell that metal must have been really cold or just so many years of compressing just cracked apart. The rails are very worn and metal is peening over the edges if you noticed in the picture. I talked about it to the owner and he just said it needed some rail work. That was before I saw the real damage. He didn't seem too concerned about how hard of a fix it would be.
I didn't get inside because I didn't have them unlock the door, but looking up through a manhole under the machine I noticed the main drive motor was removed and one of the giant brake bands was setting on a shoe.
I sure hope they're not cannibalizing the machine for parts but only borrowing some for the other machine while the component is being repaired.

I plugged some of the newly acquired dimensions into my master full size drawing of this machine and looks like I'm about as close to the real machine as I can get with my previous measurements and guesses.
I'll be starting the two outer walking shaft bearing towers first. I have some of it drawn up but need to do alot of detail work with the placement of the rivets and bolts.

There sure are a bunch. I was thinking there were more riveted joints on the exterior but now I can see. I will probably tap most of the holes and then put a nut on some. That would make the joint less likely to come loose. That's easier for me because those tiny nuts are a real pain to screw on a loose bolt. Nuts do show better detail than just a bolt head.

06-18-2012, 02:03 PM

I have a couple of questions for you steve-The towers on each side-will they have a bearing to actually support the walking shaft or will they be just cosmetic? About all those bolts-do you know how they drilled all those holes back in the 40"s? Did they have electric drills then? I remember using an electric drill in "1962" when working at a marine shop but I don't know when they first came out.
Not sure about portable drill time line but if everything was laid out in the shop correctly and punched then only minimal reaming would be needed.
Yes, the towers do support the bearings. Originally I was going to make the towers cosmetic when I started this years ago, I never envisioned being able to get next to the 1:1 machine and acquire all the drawings to boot so I'll be remachining the existing two bearings and inverting then like they're supposed to be but I want to tie it all together with some of the steel channel already in place so the tiny 0-80 bolts aren't stressed too much. 250# may stress them a bit.

Here are a couple screen shots of my full size elevations. I don't have the bearing completely detailed and no bolt or rivet holes drawn yet.

Thanks steve-I was thinking that lining those bearings up with the walking shaft would be kinda tricky but I'm guessing you know how to do that. I wouldn't have a clue about that. Judging by your pictures it's gonna look great!!

The bearings are not that hard to align. One of the pillow blocks on the interior didn't work so well because the deck flooring has never been cut and installed in that area so I left the bronze insert out. Actually now that a few years have gone by and all the walking it's done, the bearings have wore in up some. The big problem there is I need the make the walking gear parking brake. If you notice in some of my pictures or videos I have a wooden wedge shoved into the big walking bull gear locking it in the "High Cam" position for digging. If I'm not paying attention it comes loose and the shoes fall down and next thing you know the trailing cable is getting rubbed or the whole tub is spinning instead of the house.

modelman

06-22-2012, 11:43 AM

I saw that block of wood in your videos and knew it had to be doing something or it wouldn't be there. Jim Brennan told me about a circuit that will automatically stop the shoes at the correct position after walking. If this would help I'm sure if you gave him a call he would share this with you.

I'm at a bit of a loss to understand why you changed that from the original assembly you had, it appears you've now lost quite a bit of rigidity from a vital area that carries the entire weight of the model at distant end points during travel. :confused:

I'm surprised that my original has held up so well.
The bearing will be stronger once I build the rest of the tower. Like I said in a previous post; I made the bearing upside down and now I'm fixing it like it's supposed to be . Or close to.
Joe, Take a look at what still needs built to complete the entire bearing tower support.

The new updated towers and bearing blocks look incredible! Wow. So the time to cover all the inner workings of the machine is getting closer? Will you actually do it? It's really amazing to look at, and watch the drivetrain parts do their thing. All the design and engineering, not to mention the metal work that went into this model. Almost a shame to cover it with a cabin! I'm sure you'll make removable, but it's been a real treat to watch the model evolve through the last couple years. It just keeps getting better and better.

I will say I've learned a couple things from your machining process photos. Fixturing and drilling those tiny holes. What kind of adapter are you running for drilling the rivet holes? It looks like a mini chuck, but you are supporting the bit with a free floating collar of some kind? Any more info on that?

It's called a sensitive drill adapter chuck. Allows you to feed the bit down by finger pressure.

Thanks guys. Been wanting this part done for quite some time.
Espeefan,Pugs is correct on the sensitive chuck. I had to use it because I couldn't get all four plates to hold down tightly together. I broke a couple drill bits before I used the finger chuck.
I intend on covering the frame and have some of the panels removable, but it will take a while still because I still need to make the curved roof trusses and the operators cab that contours with the main roof.

Glad you noticed my simplified parts. When I started this machine several years ago, I never dreamed I would be building this as close as I am to the 1:1 Help from others and getting permission to crawl all over the 1:1 has made a huge difference on my build.

Very nice work as always steve-will the bearing support blocks be fastened to the brass panels or the main frame or both?

The blocks are attached to the brass sheets. Also there are channels under the bearing that are welded to the main frame. Some of the weight is transferred to the roof supports just like the 1:1. Now it forms a giant arch from one side to the other.
Last night my son and I pressed the walking cams back on the shaft and I'll soon be able to walk it again. There is still several hours of work needed to build the triangular braces that support the towers from flexing back and forth. That'll be my next project when I get back at it. There is so many things I have to get done before any of the house gets built.

Hi steve-there is one thing I had forgot about until I saw it on post#567-picture 8. That is the boom hoist. Could you talk a little about that. Does it work good, time to go up & down,etc.

The boom hoist is made as close to the 1:1 I could build. Gears are the same tooth count but the motor is larger (physical size) than I would like. It works great though. I power it up with a bench type power supply because I don't have a on board supply that puts out enough current to raise the boom. When the boom is all the way down on the ground the motor struggles a tiny bit but once up past about 5deg. it works less. I timed it and it takes about 18 minutes to boom up to 30deg. where I work it most of the time. The first tries with the new boom was 25deg. but you had trouble digging the roll because the bucket had to be really tight to pull it up out of the cut.

modelman

04-16-2013, 02:34 PM

I know what you are saying about the motors steve. It's a shame when someone like you is building an exact scale model and you have to use these "HUGE" electric motors. But I don't see any solution for that in the near future. You are making good progress on the dragline and I am really looking forward to seeing more.

That makes sense steve. I couldn't tell about the moisture but I could easily see the big rocks and also a lot of smaller rocks which it seems would make it hard on the smaller models. The dragline seemed to handle the rocks with no problem but I would like to see some video of how the other models worked the pile. I understand that you modelers have no choice in the dirt that is brought in. You just dig and make it work. Looks like a lot of fun.

Sooo we took the master switches and foot pedals. Wasn't very easy though but now I have them. I plan on wiring them to my machine so I can get the old time operators to give it a try. Most don't want to use the radio used now.

Got it Kerst. The seat is out of a newer truck,"air ride" but it's pretty crusty.
Notice how heavy duty the original mounting plate is for the seat. It must weigh around 150 lbs. It would swing out of the way of the two master switches so the operator can get up from the seat.
The swing pedal assembly is very heavy. I need to put it on the scale to see.
That this was a real PITA to pull up through the floor after it was cut loose. The floor is made of 1/4'' plate.

That's gonna be cool! Two questions: what is the third lever on the far left for? Propel? And is the doohickey on the back of the left console a compass? I can see where a compass could be handy to make sure you walk in the desired direction since you're facing the wrong way. Point the machine where you want to go, take a reading and then swing 180 degrees from that.

Yes. The third lever is for propel. On the Marion machine this came from, the walking function was on separate gearing electrically connected to keep them timed together, different than my Monighan style machine. The two cams on the Marion are separate with no shaft thru the width of the machine.
The box with the dial is an indicator for the walking cams showing the position 0-360 deg. so the operator knows when they are at top dead center so the machine is clear to swing.
There is also a bell mounted to the right hand console not seen in the picture that will ring when the hoist lines are near the point sheave. Very important while digging at night dusty or foggy conditions when he can't see the top of the boom.

Lots of #10 wire I had cut to get these things loose from the cab.

http://imageshack.com/a/img538/7459/sK4uc6.jpg

The switches don't use potentiometers like I thought. Looks like some sort of variable transformer that changes the voltage to the control room.

My Big question is; Does anybody know what value the pots on the Spektrum DX7 Transmitter are?
I don't want to disconnect them from the radio just yet.
The plan is to hack the radio's joysticks and rewire them to the correct potentiometers that will be installed on my master switches from the 1:1 machine.

Well I took some time this weekend to strip old wiring from the 1:1 controls to start my modification.
http://imagizer.imageshack.us/v2/800x600q90/909/jiC83D.jpg

These interesting transformer things are called "Inductors" I found this out from a dragline electrician. These take 110VAC in then put out a variable voltage up to around 30VAC. These are not going to work for the DX7 Transmitter.
Pretty cool to fool around with. I hooked one up and rotated the coil with my fingers and the magnetic field increased along with the voltage output the further I turned.

http://imageshack.com/a/img538/88/EF3pmJ.jpg

http://imageshack.com/a/img537/850/oVE2QJ.jpg

I decided to unhook one of the pots on the DX7 and reconnect the wires to a 5K pot that is mounted to the bottom of another controller I have.
Well it worked! I tried it on one of my RC trucks and my dragline switch work very well. I ordered some more 5K pots to mount to my controlls now and hope to get them to work on my dragline.

That is a nice video steve-It gives a realistic view of just what the operator sees. Any progress on the 1:1 controls? I have virtually real size movements on my dragline controls now and it is a little bit hard getting used to.

No progress on the 1:1 controls Tom. I do need to work on them because they're sitting in the middle of an area of my shop just tack welded together and I need to move it because I have a big job that needs that space.
Couldn't get to working on them because real work is more important right now.
I estimate the control module will weigh more than the model, ~500#:D

9W Monighan

06-27-2015, 08:17 PM

UPDATE. Took some time this past couple weekends and got the control platform welded up enough to move it. I Haven't got a weight just yet.
Last weekend I took a trip to an heavy equipment junk yard where I knew they had an old Marion 7400 dismantled. Asked about the original operators seat. The guy had it in side out of the weather thankfully. So I came home with it.
Today I decided to go all out and see if my idea of hacking one of my DX7 transmitters and hooking up the 5K pots to the 1:1 master switches works.
Got it hooked up with jumper wires for the big test. It worked!!! Actually it is easier to control the bucket hoist chains while dragging in the bucket.
I put about an hour of operation time in with no flaws. Haven't tried dirt though only along the concrete floor. It took a little to get used to especially the swing pedals. Now I will have to take the time to wire up some of the switches on the consoles.
This is another major milestone for this long time build. I have been wanting to do this since the beginning of this project.:)

Thanks you guys for the comments.

I have a question. Can my DX7 be powered up with 12VDC?
I will be hard wiring it into my control cabinet eliminating the 9.6VDC battery pack.
I don't want to cook it. The power supply in the photos is adjustable to 40VDC and I have it set to ~10V it is not practical to carry that thing along.
Looked around on ebay for a industrial power supply without much success. Possibly just look around at all the wall plug battery chargers laying around here, maybe I have a 9.6V one.

Good to see you got this working steve-that seat was a great find. Probably not many of those left. Does it feel strange operating your model with this set-up? Will this module be portable enough that you can take it to shows? If so I think a lot of the old operators would be willing to give it a try.

Tom, It's way nicer operating sitting up high. I have some cheap wheels I put on the bottom that can raise the whole platform up and be able to push around. I haven't tried them yet because I need to machine out some plates that lock the 4 wheels up. Maybe I should motorize it and make it walk.:D I was running it in my shop this weekend from about 25ft away. Didn't have a great view while swinging left to dump but it was fun to operate.

Steve-I guess that really did take some time to get the feel. Do you find it easier to operate the hand controls when using the foot pedals. It seems like you could concentrate more on hoisting and dragging with your feet doing the swinging. Jim Brennan told me the foot pedals have really strong springs on them. I didn't see any spring in your pictures but is this true.

Using the hand controls and your feet is sorta like jumping on one leg patting your head and rubbing your stomach then in reverse at one time Tom:D

The pictures don't show how the springs are. I'll have to get a picture next time I have the controls out in the open. Jim is correct, the springs are pretty strong. My feet get numb on the bottom and my knees get a good workout.
Jim called me the other day and was telling me he is starting to convert some of his 8050 Marion to radio control. He has a 6 channel transmitter but he doesn't know much about it just yet. I really need to take a day and go up to DLW with my machine and let Jim try my system out.

That doesn't sound like much fun steve. :eek: I think I would have a problem with strong springs but I still think this is a good idea. Jim told me he got a radio but I agree, he is totally lost. I ask him if he has hooked it up on the workbench to see how it worked and he said he didn't know how. I think he is still living in the 60's and doesn't realize how everything has progressed. I like him though-he is a great guy and I wish I knew half of what he knows about electrical systems. I told him I wasn't sure the R/C was a good idea. As big as his machines are a radio glitch in mid-swing could cause serious damage to his machine. I must admit though, today's radios are much more advanced than the ones I started out with in the 70's. I hope it works out good for him.

He was so pleased to be able to get back on a drag. Hope he shows up again next summer to giver it another try. I told him that this is one of the reasons for building my dragline and be able to let retired operator run it.

Steve-that picture of the retired operator in the seat just makes the point of what a great idea this is. Most old ex-operators probably want nothing to do with a tiny radio with levers, switches and buttons all over it but when they see the chair sitting between those consoles, this looks familiar to them and they get excited about giving it a try. Also, I am not surprised he did a great job. Anyone who did this for 20 years can probably do this in their sleep!! Maybe the word will get out that you have this and more retired operators will come out to the shows and try there hand at this set-up. The down side is the fact that it may cut into your operating time but I think this is a great thing that you have done. Hope you have fun with it!!

RC draglines are rare and this is the biggest one I have seen. this machine looks like it can manoeuvre a lot of dirt. are you using a clutch system for the winches?
looks amazing, you did a really amazing job.

This machine in somewhat ideal conditions and swinging 90deg it can move a pile of dirt approximately 44" high in about 8-10hrs of steady digging. With damp sand that number would be higher.

There are no clutches, all 3 motors are: 100vdc PM motors individually driven by 4 quadrant regenerative drives.
The only clutch is the jaw clutch that engages from drag to propel motion.
Eventually I will build the brake bands so I can set the brakes when needed.

Thanks for the compliments.

steve-I look at the discussion thread every few days to see what is going on. I meant was there anything new with the dragline. After reading that your machine had spent a long time in the trailer I am guessing you are very busy. And yes, I had always hoped to make a trip to that show but now I doubt it will happen.

The machine fared well in the trailer Tom. There is a bunch of surface rust from Labor Day because I forgot to spay her down with some WD40.

I got the incoming power supply wired up pretty well this week. Now I can shut off the power from the operators seat. I don't have the time to wire the radio up better. I want to use the auxiliary switches on the radio and wire them to the switches on the console to set the parking breaks on the 3 functions . I want to try to take all of the guts out of the DX7 and mount them to a board so it is easier to work on the wiring. I plan on having a flip down access panel on the bottom of the right hand console. That way I can make adjustments to the radio easier. Right now as you can see the radio just hangs inside the console with wires hanging out.

Thanks for the compliment.
It all started in this picture here; the spring of 1994 the day this machine was cut up for scrap. That's my 1998 Ford Ranger sitting next to the 9W. I took about 8 pictures of this machine but ran out of film and didn't take more. Originally I was
going to build a Manitowoc 4600 crawler dragline but didn't want to take the time to machine all the track links. About the year 2000 I think, the coal company sold all of their remaining machines at auction and I went and tried to buy the 1:1 bucket from the 9W but was outbid by someone with deeper pockets. My plan was to take the 9CY bucket to our steam show and set it there as a display. Actually the bucket was supposed to be taken to Station Square here in Pittsburgh to be displayed with some of the old steel mill era relics. This machine was bought new in 1939 by one of the big coal and steel tycoons here in Pittsburgh.
After the auction, A friend of mine who is good friends with the auctioneer, gave my buddy a pickup truck load of old parts books and manuals that wasn't sold. I went through them to see what I wanted and found the parts books from the 9W. From here I was able to figure out a scale that would be appropriate to be able to actually dig with. Being a machinist building this thing isn't all that hard for me but trying to get actual drawings and measurements is hard. I originally was going to wire this directly but it would make it too complicated with all the wiring involved so Radio Control came up. Not knowing anything about RC I went to a local hobby shop to ask some questions, only to find out no real knowledge on what I am attempting to build. The man there told me about a forum called "GardenTrucking" This is where I started to learn more about this hobby and met a lot of nice guys in the process. Since then countless hours have been spent on my hobby when time permits.

We got the 9W out of my trailer to get it ready for Cabin Fever Expo and I was surprised how bad it looked from the past few outings. Seems it rained every time I took it out or the humidity was so bad everything got rusty. I kept spraying the steel parts with WD40 over the years but obviously not on ALL areas.
I made the decision to dismantle the machine completely and do some much needed sandblasting and painting. I am also going to get the clutch working that shifts the drag mode to walking mode. Hopefully I can get the wiring done at the control console to make the shift.

:D will you be doing any weathering and ageing to the inside and outside makeing it look old and used that would be so cool:jaw:

I gave that some thought but I don't know how to do weathering other than how it looked prior to this rebuild. I know of a guy on the DHS Diecast site that weathers his crane models and they are superb.

Here is an example of a heavily weathered relic :D

Here is my machine the day the scrappers started cutting her up.
I originally wanted to make the house the light green with black boom ect. But now I'll be painting it Grey with the dark Green boom ect.

Looking good Steve-I see you are giving Walter Bennett a challenge on most bolts used (rivets).:D I think I see a brake band on the rear drum. Is this a work in progress? Nice job!!

Brake band is in progress. No time right now. This was one of the reasons for the tear down. Now I have the machining done on the main frame to attach the necessary parts. I was going to use servos to actuate the clutch and another to set the brake. Changed my mind because I think a servo will burn up if the clutch doesn't shift exactly as it should without binding. And if it binds, I can't hear or see it with all the outside noises at shows. I am experimenting with some lineal and rotary solenoids.

Decided to spruce up the bucket with some red paint to resemble the ESCO bucket I duplicated some before this weekends "Big Dig" at the National Pike Show. Last time out at the Cabin Fever Expo, I had trouble seeing my bucket with the lighting there. There are still wear plates and better teeth that need made on this bucket but that will come some day.

After years of searching I picked this little gem up this week. It took a long time to find just one but now I have two. One for each side of the boom.:bounce:
These are actual porcelain enamel signs Bucyrus-Erie had on their Bulldozer cable controls from the 1940's - 50's

But those signs are way over the top cool!

The red bucket was much more easier to see. Shows up better in pictures too.

The model is pure awesomeness in itself, but the signs and red bucket really do add something. Nice touches.

Haven't looked at this thread in awhile and wow great work! I wish I had that good of a detailed bucket for my dragline build!

Question what are your motors running rpm wise, im trying to size my motors for my Marion 8750 and having a hard time figuring that out on speed and torque needed. Thanks!

Question what are your motors running rpm wise, im trying to size my motors for my Marion 8750 and having a hard time figuring that out on speed and torque needed. Thanks!

I used the technical data from my machine's spec sheet to get the feet per minute from each function.
My motors are:
Swing-2500rpm 1/17hp 130vdc
Drag- 500rpm 1/12hp 130vdc
Hoist 417rpm 1/29hp 130vdc
They are geared down to approx scale feet per minute through the gearing. The drag is too fast so I have the max rpm turned down.Someday I want to build the gearbox for the drag correctly using all the gears exactly like the 1:1 machine.
I can also change my speed by changing the stick travel with the limits on the DX7 transmitter.

It has been very hard to find any time to focus on this due to being busy at work all the time.So I found some time to do a little work on my 9W before Cabin Fever. Since it was very hard to see last year at the show I painted the bucket last summer and I added some lighting to my boom. I bought these bolt LED's and turned them down to fit inside of some old Lionel flood light housings.

Well I found a little time to break out my model again and get to some more parts that need made. I decided to make some roof trusses and get some cover on this thing.

I made a simple fixture to machine the "T" bars since you can't buy the size I need.

https://imageshack.com/a/img921/3517/bfdCrg.jpg

A little scrounging around and came up with a cutter stack to mill these with a .040" web and flange.

Four cuts to depth and they turned out nice. Bigger cuts caused some problems.

A few ready for next step

Only problem I see is, no one will be able to see the great workmanship inside if you get it all covered up.

That has been plaguing me for quite some time.
Some people ask me ; "When are you going to put the skin on it?" and some like to see the internals.
My plan is to make the house but also make it removable on the left side.
That way I can show off the machinery and be able to see if the wire ropes get screwed up . The operators cab is on the right side and that will need to be attached securely.
I hope to have scale operator in there with the controls working in unison with my movements on the 1:1 controls and some of the red and green lights on the control switches working as well.
