Re: Skeeters contracting services
It's been long days at work this week, (I'll take ALL the hours I can get now, cause I know they'll dry up in a few more weeks) already got almost 48 hours in for this week, after a 10 hour day today. Since it wasn't a terribly long day, I opened a ton of mail that had accumulated this week. I didn't take pictures of it. The new servo mounted winch spools for the log skidder arrived today. I'll have to modify them a bit, to make them work, but my Dremmel, & I can make it happen. ALSO, both of my new employees started work today. Perhaps tomorrow, or this weekend, I'll snap a few pics of the winch spools.

Re: Skeeters contracting services
The tracked loader was inexpensive from www.RuralKing.com . So inexpensive, that I bought two. Seems that I always mess up the first try, so this way I have the 2nd attempt already here.

Re: Skeeters contracting services
Well.............Having today off I did a little tinkering in the shop. I got a little more done on the Bruder D5 conversion. I crafted this part to re-seal the unit. I had to cut a bit away to fit the drive servos in place. I DON'T want a bunch of mud/dirt/debris getting into it, so I came up with this. Shoe Goo holds it all together.
https://farm5.staticflickr.com/4364/...c87b87d3dd.jpgunnamed (6) by Anthony Kalnoski, on Flickr The former shop foreman, here's his new home. He's installed into the seat with double sided stick tape. I DON'T want him to leave that cab, & have another tantrum. Doing so may run off the rest of the hired help. https://farm5.staticflickr.com/4502/...e96732996f.jpgunnamed (4) by Anthony Kalnoski, on Flickr Here's the inside of the dozer. I re-used the weight from the FAILED attempt I did before. Also The 3D YELLOW grill, is cut to accept a servo. I HOPE to use the servo to lift the blade. Right now the yellow grill is temporary, while fitting everything together. It's yellow because that's the filament that was loaded in the 3D printer at the time of printing it. Later, once I get everything exactly figured out, I'll re-print it in BLACK so it looks more like the 1:1. A big Thank-You goes out to NebraskaTrevor for the STL file of the D5 grill! https://farm5.staticflickr.com/4468/...993f0529de.jpgunnamed (7) by Anthony Kalnoski, on Flickr Remember those sanding blocks I printed a bit back? Well I thought they were too lengthy. So.....................I cut them in the miter box with the wood saw. I couldn't justify wasting ALL that time & material to throw them away, so I modified them POST print! https://farm5.staticflickr.com/4340/...1e09c2bd7a.jpgunnamed (5) by Anthony Kalnoski, on Flickr |
Re: Skeeters contracting services
With this style battery holder,
http://www.ebay.com/itm/2Pcs-Wired-C...30MrCHVOhee4yg If I attach a charger to it, can I charge the batteries while in the holder. I ask as I would like to keep the batteries inside the D5 Bruder conversion, rather then have to remove them to charge them. OR, if you guys have a better suggestion, I'm all ears. I already know I'll be placing a charge port on this thing. It's easier to open than stock, but will still be a PITA to open JUST to change/charge batteries. |
Re: Skeeters contracting services
Today, after a short work day (Rare that they let us work on Sundays, as they DON'T want to pay the DOUBLE time :( ) I made a little more progress on the Bruder D5 conversion. :) I DON'T have anymore HiTech servos like I used for the drive motors. They're on a SLOW boat from China. So.............I mocked up the blade lift with a Traxxas mini servo. https://farm5.staticflickr.com/4469/...8a0dbdbd91.jpgunnamed (8) by Anthony Kalnoski, on Flickr
I found an issue! I'll have to make a spacer to mount between the servo & the grill, to make clearance room. The linkage binds on it's self. I think if I add a spacer to push the servo into the grill farther, I can overcome this hurdle. https://farm5.staticflickr.com/4464/...9d6b3e93d5.jpgunnamed (9) by Anthony Kalnoski, on Flickr Now I have to await the rechargeable batteries, holders, & on-off switch to arrive on the fore mentioned SLOW boat. Once I get all these goodies, I'll hopefully have this model buttoned up within a few hours! :bounce: I intend to mount the On/Off switch at the rear of the operators compartment, behind the drivers LEFT hand side. I think there's a good opportunity to place it there, & have ease of access to route the wiring. Also it'll be easy to turn on & off there. |
Re: Skeeters contracting services
Well...............Since work decided that I get to work graveyard shift tomorrow, I get to stay up all night re-adjusting my sleep schedule. :( So..................I figured I'd start on the Leibherre wheeled loader. :) I already have all the 3D parts printed for it, & everything I need on hand for it. I'd finish the D5, but I'm still awaiting the slow boat from China to bring the remaining arts for it. :confused:
I'll be using the design Stein posted in his build thread, but with my own twist to it. Feeling that this loader needs a little more weight to it, I'll be adding weight to the tires. For now, I'll be adding half a pound to EACH wheel. :confused: HOPEFULLY that will be enough? The weight will be epoxied in place to prevent lead exposure. HOPEFULLY I'll get a ways along with this conversion tonight. The lead is solid core 1/4 inch fishing weight. I unrolled it, measured it, & cut it in half. I DIDN'Tweight it. I figured as long as it's relatively close, it should be fine for hobby usage. :cop: a pic showing the before/after shots of the weighted wheels. https://farm5.staticflickr.com/4459/...f2815be3e8.jpgunnamed (11) by Anthony Kalnoski, on Flickr |
Re: Skeeters contracting services
I've been thinking about the same thing! I've been prototyping with adding steel wire 4mm) inside the wheels, but your lead approach looks more doable. The handling will be much better with the added weight in the wheels.
Stein :-) |
Re: Skeeters contracting services
Well................I DIDN'T have all the stuff I thought I had. I had it all, but DIDN'T have enough of everything! The wheels I used ALL the epoxy that was suppose to do the WHOLE project, just to do the rear wheels. Even then, I fell short of materials. The 4mm Screws I have, AREN'T long enough to pass through the wheels, let alone the adapter plates. I did what I could, with what I had.
Each wheel took around 6 U.S. Ounces of epoxy to fill. I had planned for 3Oz. per wheel. I thought I had some more of it from a previous project. I DID, but it wasn't any good. It had hardened in the bottles, it was so old. Here's what I got done, with the supplies I had. One wheel is completed. The other still needs about 2Oz. more to finish. https://farm5.staticflickr.com/4458/...d58cab6082.jpgunnamed (12) by Anthony Kalnoski, on Flickr I got the holes all drilled into the rear axle. I used blue Lock-tite on the mounting hubs to the motors. Pictures beside this is the lead I bought to use for the wheel weights. One spool does 2 wheels at a half a pound per wheel. https://farm5.staticflickr.com/4481/...e1a378725e.jpgunnamed (14) by Anthony Kalnoski, on Flickr https://farm5.staticflickr.com/4464/...b2857f1bc0.jpgunnamed (13) by Anthony Kalnoski, on Flickr The motors I intend to use are 12V 80RPM motors. They may be a bit fast for this project BUT..............they are what I have laying around. I figured I'd put them to use. Long story on how I ended up with 30 of them. I ordered them form Deal Extreme. I paid with PayPal. the website said my payment DIDN'T go through. I looked at the online bank statement, & it didn't show the PayPal transaction, 30 minutes after I made it. I re-sent the payment. The website STILL said it DIDN'T process. 30 minutes later, after STILL not seeing a PayPal transaction, I re-sent payment AGAIN. Once again, the website said the payment didn't process. At this point I gave up, & went to sleep for the night. the next morning, I awake to find 3 PayPal transactions had cleared. I also had 3 emails form Deal Extreme, stating that my order was processed. No worries, I thought, I'll get my 10 motors I ordered. Fast forward a few weeks, & I get home from work to find 3 packages from Deal Extreme awaiting me. :LOL: |

Re: Skeeters contracting services
Yes, you can hook up a charge port to a holder. I'd install a charge/run switch if your charge port doesnt have it built in.
I'd rather use 2/3A or Sub-C batteries instead of the AA that work with that holder. More capacity, higher charge and discharge rate, more flexabiliy in where the batteries go, can do a 6pack if your esc prefer it to the 4pack. |

Re: Skeeters contracting services
That SLOW boat from China arrived today. It brought my 4 new HS85MG Mighty Micro servo's. ONLY 3 are still in the boxes, as pictures here
https://farm5.staticflickr.com/4503/...3d33d2e1f4.jpgunnamed (16) by Anthony Kalnoski, on Flickr The 4th one has been opened to test fit into the D5 conversion. I'm pleased with how it fits so far. Since I hacked the grill to test the theory with a Traxxas servo, I'll be 3D printing another grill to test fit it with. I think I'll start the printer now, so the part's ready when I get home from work. Although I DON'T remember exactly where I saw pictures for the grill mounted blade servo, I know my success was limited with it. The set up kept opening the model due to the torque applied to the grill. Here's the idea I came up with to mount the blade servo, & solve this problem. That aluminum piece is bolted to the bottom of the dozer, & then I bolt the servo to it. The new part will take the torque abuse, rather then allowing the grill to work side to side eventually opening the model. The cut out in it was hand machined with my dremmel tool, the flexible extension, & a the cut-off wheel. The new grill isn't yet installed in this pic, but everything lines up properly when it's put together. That pic doesn't have any bolts in it for the servo,.......YET. It was just a quick mock up to give the idea how it would be when done. https://farm5.staticflickr.com/4482/...4f0d89f195.jpgunnamed (15) by Anthony Kalnoski, on Flickr |
Re: Skeeters contracting services
2/3A battery.
https://www.maxamps.com/nimh-1600mah-2-3a-nimh-cell (2/3 length of an 'A' battery) You'll either have to pick up some solder and bars or wire to build the pack. Shoegoo or epoxy work to keep the pack rigid. I like the new servo mount, should be a lot stronger. |
Re: Skeeters contracting services

Yes, much stronger is the new mount. Once work FINALLY finishes for the day, I hope to get 'er buttoned up with that part of it. |

Re: Skeeters contracting services
Charging help. PLEASE, & thanks. I'd like to find a charge port that I can easily mount, (Drill the hole into the plastic, insert charge port, secure with a jam nut) to the Bruder D5 conversion. I would like one that bolts/screws to it permanently. I've searched Ebay for charge plu, & charge port, but DON'T find what I seek. Any ideas?

Re: Skeeters contracting services
I already run Deans on all my stuff and i like simple, so i'll probably do something like these 'deans panel mount' (once the bobcat conversion eventually starts...)
https://www.thingiverse.com/thing:1733664 https://1080aerial.com/products/dean...luminium-mount But i'm also lazy and prone to lose special adaptors for things. Normal batts have deans, charger has deans, pass-through gets deans. Same is good. |

Frizen, TYVM for all your help on my various projects! I took your advise, & have ordered these 2/3A batteries. I ordered them over the suggested link, as they already have the bars build into them!
http://www.ebay.com/itm/12pcs-a-set-...72.m2749.l2649 I've got this switch on order for the charge/run/off switch. HOPEFULLY, it is the right kind/type, & will work for what I intend to use it for. http://www.ebay.com/itm/1PCS-Mini-To...72.m2749.l2649 |
Re: Skeeters contracting services
Glad to help. My suggestions are usually just the first site to come up to show what i mean, not an 'order here'.
2/3 AA should work too, they're smaller (DoubleA size girth, put your thumb over the duracell Coppertop) so you should be able to stick them more places, and the 600 mAh probably won't hold you back too much on a Dozer. Hard to argue wit $0.50/cell. - - I just like 2/3A since i find it to be a pretty great balance of runtime and size, usually you can get 1500-1600 mAh which can run my 1/10 comp crawler for 15 min, 1/14 van or dumptruck for 30+ min. Not sure about the switch, it's only showing vac ratings, so no idea about vdc ratings. That would take time tracking down a datasheet if available or trying to figure a safe amount to be derated. All i can safely say is Maybe. Bench test it hard and see if its getting warm or any suggestion of arcing. |
Re: Skeeters contracting services
I don't think run time should be a factor too much with this model. the batteries ONLY have to run 3 micro servo's & the 2X5 Sabertooth.

Re: Skeeters contracting services
Today I placed a Team Associated NMH battery into the Bruder D5 conversion, just for giggles. I wanted to see what it would/could do. After I ran about 3 passes of 2 feet long, I had a decent pile. I then turned the dozer around to push that pile so I could push a FULL blad of gravel. The battery died just after I got the camera set up & filming, so this is just a teaser vid.

Re: Skeeters contracting services
Yesterday I took the Bruder D5 out for a trial. In the initial test run, I found an issue. The blade controll linkage was moving. The nut I installed on the back side of it was NOT tight any longer. SO...............I mixed up dome epoxy, & tightened the nut. To keep it from happening again, I filled in the cavity with the epoxy.
https://farm5.staticflickr.com/4451/...5732da0de7.jpgunnamed (17) by Anthony Kalnoski, on Flickr I also made a little progress with the front loader. I'll have to take pics of that. I WISH there was a way to speed up that SLOW boat from China. I REALLY want my parts, so I can complete this build! |
Re: Skeeters contracting services
Nice to see it's pushing gravel already.
I really like nylock nuts or blue locktite for most things once you finalize a design. Wait until you find your trucks driving along at a meet and suddenly the back end jumps wildly, and the back starts trying to pass the front, and it locks up... or you have one at a comp being judged through the gates decide it needs to rip an axle loose and bounce its way down the rock face... . Nylock all the things! |
Re: Skeeters contracting services
Frizzen, THANKS for the tip. I never thought about it before. I know it's premature, to be working it, but I couldn't help it. I just had to see if it was going to work as I hoped it would. The micro servo's are REALLY slooooooooooooooooooow. I wish I had used FULL sized servo's in it. Perhaps then it would be a little faster.
A quick question, (pardon my sloppy sketck, it's the best I could do. I'm not artistic) In the sketch I've drawn below, is this the proper way to wire a run/off/charge switch into a model? Where EVERYTHING converges, I forgot to draw the battery, at the bottom of the sketch. The bullseye looking thing at the left, is suppose to be the charge plug. https://farm5.staticflickr.com/4483/...c7790199b9.jpgunnamed (18) by Anthony Kalnoski, on Flickr |
Re: Skeeters contracting services
I think I found better(BETTER as in MORE bang, 3.7 V per cell, as opposed to the 1.2V per cell I have already ordered) batteries. I found this holder, & batteries on flebay. I've never used the LiOn battery before. Are they good batteries?
http://cgi.ebay.com/ws/eBayISAPI.dll...=1609013003006 http://www.ebay.com/itm/Plastic-Batt...72.m2749.l2649 I worry, with LI, like the LIpo, LIpo needs balance boards per cell. DO LIon batteries need a balance board, or can they charge like standard rechargeable AA batteries? |
Re: Skeeters contracting services
Smallhaul ha several dozer or bobcat builds that replaced the standard hs645 with the digital version of it since they have a faster transit time, maybe look into those specs for the size you run? Check the channel endpoints, you might not be giving the motor control full range/speed. You might also have a dual rate setting turned on in the tx.
No, that drawing will let smoke out. All the grounds can just be tied together. Put esc + on a side, put battery + on center, put charge + on a side. I'm not sure if you're using a 2 or 3 pos switch. You want center off if you have it. One throw connect charge to battery, other throw connect esc to battery. Li-on isn't used much in rc. Its safer than lipo. You don't generally have much of a C rating, the chargers are kinda weird, and a lot of them have a circuit that bricks the battery after x time or cycles. Hopefully someone knows more about them than me. |
Re: Skeeters contracting services

No "C" rating is a no go for me. I DON'T want to hang around forever waiting for it to charge. |
Re: Skeeters contracting services
I've used Li-ion batteries in some robotics projects and a couple of RC-builds:
- Bruder MAN truck: http://www.scale4x4rc.org/forums/showthread.php?t=80393 - Bruder Delta loader: https://www.rcsparks.com/forum/threa...dded-pc.36063/ and I think they work very well for smaller sized RC projects (and Tesla uses them in their cars, so evidently good for larger models as well). I typically now just buy single 18650 industry standard cells (like Tesla) from a well-known brand like Panasonic: - NCR18650A 3.7V 3100mAh http://www.ebay.com/itm/292133363075 You have to look up the datasheet to get the C-rating. For this one, the NCR18650A's datasheet: - https://na.industrial.panasonic.com/.../ncr18650a.pdf says the maxium charge current is 1475mA. Charging at 1000mA is thus very safe, you could probably also go with 1500mA. With the 3100mAh capacity, you are looking at 4 hours charging time with 1A charger. But for a small RC model, the 3100mAh will also last you a whole day, so the charge time VS run time is a good ratio. The 18650-type cells is the same type that Tesla use in their Model S and X cars: - http://fortune.com/2016/07/27/tesla-...y-gigafactory/ I combine the cells in a battery holder with a battery protection circuit to avoid over discharge, over voltage, short circuit and other things that could hurt the cells: - http://www.ebay.com/itm/381100264951 You can get these holders in any configuration, 1S, 2S (7.4v), 3S (11.1v), 4S, etc and parallels, e.g. 1P, 2P, etc. and finally I use a charger like this one: - http://www.ebay.com/itm/191941924713 it's just a standard CC/CV charger, like your typical RC-charger for LiPos. You can of course also use your normal RC charger. On top of that you can also charge the cells individually in parallel using a charger like this (but I've never done that): - http://www.ebay.com/itm/272685459838 You can also get the battery packs pre-build with protection boards, and even in very large size batteries. I use batteries like these in my robots: - http://www.ebay.com/itm/291652625112 Best regards, Stein :-) |

Re: Skeeters contracting services
WELL.....................poop!
My RANT about EBay sellers follows! I JUST now saw that the Ebay seller of the charge plugs for the D5 sent a message last night. I read it, & was disappointed! The shipment WAS due to reach me in 3-5 days from now. They tell me they HAVEN'T yet shipped it. Something about problems with their distributor(s), or some horsesh!t like that. They tell me it'll be 10-15 days before they have inventory to ship me. Asks if I'd like to wait on them. WTF? REALLY? You contact me a few days prior to the delivery date to tell me you DON'T have the product you sold me. You then have the gumption to ask IF I'd like to wait on you! I requested a cancellation of order with a refund, & it was granted. The ONLY reason I ordered them from the original seller, was they were shipping from California, rather then China. China takes a LOT longer to arrive to me, then does mail from Ca., & I was willing to pay the difference for the speed that they'd be here to me. Now I've re-ordered the plugs from a different seller. Unfortunately, they ARE comming from China this time around. That said, Once the Batteries, & battery holder arrive me, I'll be delayed a bit till I can get the D5 finished. |
Re: Skeeters contracting services
It's getting colder outside. Winter's ALMOST here. Yesterday morning I had to scrape ice form the windshield before I left the house. Knowing that epoxy doesn't like the cooler temps of winter, I decided to get the other set of wheels done for the front loader. I thought about it for a while, & decided that the ones that have 1/2 # of lead added to them should go on the front. I also decided that since the rear of the machine SHOULD be heavier then the front, to add as much lead to the rear tires as I could. I got about 3/4 of a pound of lead crammed into each of them. I then epoxied over it as I did the others.
