Tangential Toolholder

[how'sitwork?]

Having now made 4 of various designs I am experimenting with the sharpening fixture angle. 20' works well on mild steel and aluminium. The tip of the 30' version ( that's the bit from the jig which angles the bit up at 30' to horizontal) although sharper doesn't seem to be any better on aluminium which surprised me. On steel it definitely chattered more (visible on the finish).

I copied Arbalest with a clamp for both of the sharpening jigs I've made as it got a bit hot to hold rather too quickly for me ( too impatient!)
