A flow-degas tube. Basically a large clear PVC pipe and lots of threads and O-ring seals. Big endcaps are polypropylene. Also singlepointed internal threads for the first time here.
polyethylene jaws to hold big (101.6mm OD) toroid stack. Fits mild steel bars tied to Wilton bench vise.
turns a round hole into a hexagon. Tapered hex stock down to round, then cut teeth with a little relief. 1018 mild steel. It cuts aluminum or plastic. Experimental but it works pretty good!
