I've been working on designing a jig and have a few questions for those with the expertise before I go any further.
Looking at mimicking the arctos jig with a few changes. I'll be using 80/20 extrusions, the long beam is 40x120 and vertical is 80x40.
The two questions I have for right now are:
For the HT and ST cones, at some point I would like to add purge fittings for argon. I think for the HT I'll have one on the top cone, but I'm curious where the bleed should be located? The way I have the cones installed right now is a thru-hole threaded m8, a location pin on the back side that will be pressed into the angle bracket and then an m8 bolt to thread into the back side of the cone. I'm hoping to get something done without purge fittings as I believe they are something that can be added later pretty easily (possibly just re-machining the cones).
My other question involves the ST mount. Right now the pivot runs on a track with two pins (not visible) and then the single lever to tighten it down, which threads into the base plate that slides along the 40x120 extrusion. Most designs I see are this single lever for clamping, is that enough?
And a picture that will hopefully help with what I am asking
