What is the thikness of the plate to use for cutting ?

sorry about mistakes, i have edited it in SolidWorks, and converted, something about conversion is a problem i guess,

You multiplied your measurement by 5. I've assembled the stl parts on a cad program and got the shoulder axis distance of 287mm. Shoulder pins are 8mm by my calculations. You dxf had the pins at 40mm, so dividing by 8 I got 5. Dividing the your axis distance of 1433.89mm by 5 I got 286.778. So scaling down by 5 should fix it. The other problem is the there is a difference in the shoulder axis between the front plate and the back plate. The corresponding measurement being 1435.36mm. Big difference here but when scaled down the difference is 0.294mm. That's a fairly big misalignment over the short distance of 56mm front to back.

This DXF is made with too many mistakes, many open connections and repeated lines, also polygones instead of circles. My watercut master went crazy, when he saw this :)
I have refined and corrected all mistakes. Will upload soon

I plan to use this to watercut a whole torso> I hope i will work. It's cheaper, that printing torso on my Stratasys

if i change the parts i should make some hinge parts for rotating parts (like pistonbase, piv center). thin sheet metal can cut those abs parts.
but you are right if i can design and manufacture some parts in lathe, or if i can weld some pipes on it i can completely change abs to aluminum,

Hi, interesting. One question why do you need to reinforce them with aluminium plates?

What I mean is, it would be better to simply replace the plastic parts with the the laser cut plates, no?
