I see you got all the paper work done, now it's time to take a journey in your mind to finish it. The rest of it isn't on paper is it. I'm sure you can come up with something to make it work.

I couldn't figure it out myself until I seen it open, then I knew it was based on a big turret operation type deal.
But that is not going to be easy to put it in, and make it work.

what thickness of plastic you using for your projects? I wanna get into doing this, so i was just curious.

Thanks

All,
Have been having p-c problems again----no e-mail out or in ....sorry if you have been waiting..Kerry,
Adam..........plastic used can vary a lot depending on what I need... to get the strength or shape....eg---
the "arms"are 30thou with 40 th "spacers "or "I/H" beams covered with10th overall to give smooth finish........
the "cupola"is a10th "circlet " front and back with 40th internal braces(2 of them are to take the pins to hold the "main arm".)..top is 30 th and "slopes" are20.........
sides are 20th......"dozer"is 20th...all"hydraulics" are various tubes to nearest "size"...(pics to follow)
Hope that helps
aye
BARV
