So, last spring and early summer was spent fiddling with the design. pretty much functionally unchanged.
What has changed is i redesigned pretty much every plastic part to be printable on my home 3d printer and simplifed everything as much as possible. And spend hours and hours trying different filaments types, brands, and print setings. Now i can print or machine all the parts needed at my home shop. printing takes about 40 hours per pair of bindings. yeah, FDM 3d printers are slow.
pretty confident about all the parts, except one aspect of the riser. if that proves too weak in FDM (it was fine with SLS and MJF), i have a design that adds a stainless support tube.
before getting the pics, here are the parts and descriptions:
threaded swage: machined from a vented 1/4-20 set screw using my micromill as a lathe (set screw in collet, lathe bit in vise)
cable: cut and swaged with hand swager
cable adjuster barrel: 3/8" OD aluminum tube cut to length, cleaned up, and threaded 1/4-20 down the center
cable adjuster cap: 3d printed from eSun PETG held into barrel by 1/4-20 screw (head of screw takes the load)
Spring: Axl Stiffy
heel cross bar: machined from 1/2" aluminum rod using my micromill
heel pad: 3d printed from eSun PETG
heel throw: 3d printed from Taulman Alloy 910 nylon
leash pull: 3d printed from eSun PETG
Riser: 3d printed from Taulman Alloy 910 nylon
