Henry, Look in my 1:1 topic but that's my kids toy I built him back in 97' It's just a little Struck Mini Dozer I modified to resemble a Cat D4C about 1/2 scale I added a hydraulic blade also.
Pugs, That's only about 1/4 of my shop, there's more back in the darkness. We have about 12,000 sq.ft.

I got a few pieces cut this weekend on the second or middle 30-3/4'' (41') boom section. I had to do some serious filing and sanding to remove the machine marks from the Tee chord sections too.
I could have gotten more done but had the urge to operate the machine with the temporary boom on for about 2+hrs




Some tubes cut for both sides

Looks like you are making some progress steve-are you pleased with the way the model works with the boom section on? Is it strong?

I can't try the first section yet. If anything I'm going to just wire tie it under the temporary boom for looks and to keep fingers from touching it while at the show. But to answer your question Tom, It is very strong so far, much stronger than the temporary one that's just tacked together 1/8''x1/2'' flat bar.Also the safety lines add needed strength to keep it from buckling. I am almost finished milling angles and notching the tubes on the second section. After that is done I have to work on those dreaded splice plates again that took so long on the first section.

You will have to come next year with all your forestry equipment . IH steve and I talked about having a stripping diorama starting with cutting trees then scrape the topsoil off and start removing overburden down to a scale coal bed to load out I was saying around here in the past, the coal co's just push all the trees into the pit and cover them up with a D11

I need parking brakes for the load drum and walking gear. Now I know more about RC I can figure this out. I wasn't sure If I should use air but I guess a servo is the easiest. Not sure the exact capacity of the bucket.

Does anybody know of a source for lighting? I want some big spot lights on the boom. I was thinking of buying Mini Maglite reflectors and build my own using their Kypton bulbs. I found I site that has model boat spot lights. I may get one and see how it works.

On my model I will try using Plexi cut to size, drill a hole on rear and put a white LED.
The Plexi was bought as scrap at local dealer, LED´s are 5 for $4. Plexi comes in different sizes, sheets, rods, I use 1" sheet (part of) and cut with bandsaw.
My LED´s are 3,2v 20mA, 2 connected togheter can be runned on reciver battery.

The brass strip will be used as guards outside lamps (on CAT models).
