I’m running parts for it right now, but might as well make a post.
I’ve been running a few multi sided parts, and I’ve made a few attempts at 4 sided parts. The biggest challenge I have with 4 sided parts are how much stock prep work needs to go into the process. I was trying to do a swole pikachu a few months ago (made out of Ash wood), and I think either my zero was off, or the stock was slightly off. This led to the model not lining up during machining:
I’ve been thinking since that project that a jig would make things way easier. At first I was going to do a 4 sided jig, because I’m not quite sure how to machine on other angles/orientations in fusion. But seeing how @Vince.Fab made the 12 sided jig for the, and also just thinking about things, I figured an 8 sided jig would give me enough future capacity to have a thing I can use regularly without needing (super soon) to upgrade to something else.

Anyways, plan is to make this guy (edit: looks like that’s an older picture. I’ve reduced the height and removed the top flair outs of the octagon to make removal more easy) :
Holes to the left and right of the octagon recess are for the tiger clamps. Since I’ve been making things at various sizes, the tiger clamps should give me a bit more stability to the stock (but may not be required). I likely could’ve gone a bit larger with the jig, but right now it gets me the ability to do up to 50mm tall parts. I think I’d like to play with it before making a different one, that might be larger.
The plate that stock will secure to will have threaded holes at the outer ring to match the through holes on the recess, and also have holes for securing stock material to. I may make a few different versions if I find any limitations. I hope to have this finished by midweek and run a part or 2 with it to see how it works, if my assumptions are correct. Again my hope is that it helps with reducing the stock prep time.
More to follow.
