No models with combustion just very realistic sound and smoke modules....

Maybee if I say that I have the most/best realistic sound and smoke module inside

Have still some parts to do, one major assembly is the hydraulic control for ripper tooth. My big steel cutter can´t be used right now, don´t have any electricity in that shop anymore (mowing out) so did some CAD on needed parts to be laser cut. Will probably take a couple of weeks before getting the parts but feels good to have this going. Also the sheet metal parts for hood will be done at same time. Those parts are the last to be manufactored (exept for new windows for cab), I hope. Then testing will start

Some printout from program, all major parts, in total this will add up another 60 parts




With some yellow paint on. This cylinder will not be hydraulic operated, don´t have any valve position or RC position left. It will be spring activated, push cylinder rod in and ripper can be adjusted. Maybee later it can be changed to a electric cylinder but don´t think it will be used that much.


Since working with ripper assembly this was removed from dozer. Have never had it without any attatchment so got some photos, this way with scraper it will look like some bigger machines at McAninch.




Will come back when parts done

thats cat is sweet, but i want to see the lowboy and tractor you build to haul it!!

Very nice Dan, what a great build this is!

About laser, we got a laser shop in Borlänge called Borlänge Plåtteknik, http://www.dpt.se/system/visa.asp?HI...825&HSID=15710, they have helpt me with some laser cutting and make it quick. If you like to try, talk to Fredrik. //Kalle

There has been plans for building this, but it depends on if I can get some drawings to work from. As you might know, I´m living in Sweden and we have different lowboys here, if I build one it should look like an american, Rogers or other brand. Guess it´s hard to get drawings, next option is to make my own drawings (need to go over there ). If anyone have connections to a manufactor, please let me know, don´t need production drawings, only a nice drawing showing main sizes and positions with side- top- rear view.
Have a KW drawn, as with all rolling models, biggest problem is to find tires looking like the real ones.

About electric drive, there´s always a possibility to change way of powering this model, it´s not that hard to remove all hydraulics (exept for cylinders) but you will need some big batteries to get the power. But I will try with gas engine first, if that fails, that problem has to be dealt with then.

Progress, last (?) parts on order now (Kalle, have a good supplier close to where I live, thanks anyhow) hope to get them before christmas.
Did buy some thin glass (1,7mm) sheet, will try make windows in real glass.

Hi Dan, here is the link to Roger trailers
http://www.rogerstrailers.com/
I saved the site for that very reason they have drawings with dimensions, hope it helps. The build is coming along nicely.

Hey Dan, You may want to cut the glass to size then see about getting it tempered so it won't crack easily.

Thanks, did look there on a 50 ton lowboy(CR50PL), scaled down to D8R size (1 to5,6), the trailer alone will be 9foot long! Unfortunatly it looks like the drawing is not so good for detail, have to enlarge it with 1500%, but it will give main messurments. Guess christmas holidays saved behind computer making some drawings.

Steve, I will try cutting the windows first, not sure I can do it, is it specialist that tempers the glass?

That thin of glass is not difficult to cut if you score it correctly with a good glass cutter. After cut to basic size, you can grose with pliers sand or carefully grind to get the rounded corners then sand smooth. You should be able to go to a glass shop and they could get the pieces tempered for you. I learned how to cut glass at an early age in my grandfather's stained glass shop.

Steve,
I got a Silbersch cutting head in the deal with glass, looks like a good tool for cutting. Will keep you posted.

Truckmaker, did go thru Rogers sales documents on there web site, They have some nice drawings like for this 50 tonner



But on other hand, I have a crush for California style lowboy like this Murray



Not a drawing to build from, have to make some contact there, think the Professional has some advantages, not so long as Rogers trailer.
By the way, have you 1/16 seen this trailer, they have one for sale, no price tag seen



Dan

[D8R]

Did try milling the track shoes (keeping track in place) on bogies. Did take nuch longer time than expected. Had to start making some angle bits to use as guides when milling



First one done, will see if I do more or wait for Santa, maybee a cnc for christmas

Have been looking for one, maybee next year



This is the look when mounted, 15 more to go


And last but not least

A very HAPPY HOLIDAYS to you all!



(and last pic, you can use a D8R moving snow, here my friend with the proto CAT). This is from 2 years back but we have same amout of snow this year. Ofcourse the machine is to heavy to walk on top of snow, have to use a D6LGP there.

I can't help but to set here and look and study the pics and details of you dozer build it is just very nice work

Hi Dan, Sorry It took so long to respond, I missed the thread update, yes the drawings they have on the sales sheets are great, it was the main reason I posted the link. I have not seen the Murray trailer it looks nice! I like the multiple duals on the axles and lightening holes!

No problem, not decided yet if going east or west coast style. Have a Rogers 35 ton trailer for my full scale Pete, no problem with sizes there.

Thanks Henry!

Did some more milling (no, Santa didn´t come with cnc) on rest of all shoes needed. Amazing how much time can be spent making small parts that for most observer will never be noticeable. But they have a reason, guiding the tracks. (yes, there is one to much, spare part)

All done, threaded M4


Will sandblast blade and ripper parts tomorrow to get a nice surface to add more details. More about that later.
Dan

[D8R]

Did get laser cutted part this week, still gets very exited when new parts arrive. And there is some times supprises, forgot one part and had some minor miss alignment on some others



Did blade cylinder piston cover, don't know if this is a CAT part but it makes sence. Pusherarms was also modified, the right one with an extra cylinder cover plate.


Left one with 3 different holes to set angle of blade and new square push arm


Still to do on arms are the ladder steps on outside and a more prototypical conector (end) to dozer


On blade I made some more details, covers for cylinders, holder for GPS reciver and blade angle reader with cover.


1st time I did mill a part like this,


GPS antenna made, lenght to be adapted as soon I have correct heights.


Some parts for ripper tooth control was also cutted, here some TIG welded together (new expirience to me)


Cutting windows for cab on hold due to computer problem. Have an old Windows 98 computer with CAD program. The printer broke down and is not possible to replace with a newer one (needs higher than W98). So now I need to find spare parts to get out the drawings to use as guides.

Love seeing this kind of fabrication work. Keep it coming!
What does the blade weigh?

[footprint]

As usual amazing build thanks for the updates, did i mention we love pics

Could you save/export as a PDF and print elsewhere? depending on the filetype you could export the plot file, just a suggestion but i've no idea on such an old version of Solidworks.

Keep up the fantastic work can almost smell it running

Thanks Steve, yes it felt good going back welding again (still beginner at that to)
The weight of blade is 54lbs or 25kg but you get a good grip on it holding in guard. The pusharms weight another 16lbs.

Thanks, yes hope to to smell engine soon, been waiting a long time for that.
Pdf could be a solution, remember getting some distorsion (lenght vs height) when making pdf sometimes, will check

Pin puller assembly done (except for pins instead of bolts)
CAD model:

and how it turned out:


Do not have room for any more hydraulics so it has a spring loaded cylinder.
Testing doing videos with the dozer cam, see here:
www.youtube.com/watch?v=TsZIEjif7eM

Spacers inside ripper assembly (where tooth will be) will be milled in alu and bolted in place. Not shure how tight/loose the ripper should be, some movement needed for shure. Will get alu tomorrow, pics coming.
Have a nice monday night!
