So, I made a dado (table saw) and needed to clean up the bottom.
Seems like an ideal job for the router plane. Except the dado is ¼” and I only have the ½” blade. Soooo, a chunk of scrap 3/8″ stainless rod (¼” is too small to be clamped in the plane), cut a vee on one side and a slot, then a bit of ¼” O-1 plate welded on the end, grind, heat red hot, dunk in veggie oil (smells dandy, motor oil is incredibly rank), temper in the oven and spend way too much time on the diamonds (gotta learn to draw the temper a bit more) and next morning, voilà, ten minutes to a nice dado.
- Nipple spear take 2. Got smart and copied the commercial version. Learned a few things about work holding, the bulbous end fits both a collet and a center. On a manual lathe you flip it couple of times. Two tapers.Spoke spear - for digging nipples out of a puddle of linseed oil and putting them in a deep(ish) dish rim socket. Serrations really help retain the nipple. No idea of the angle, just stuck a shim under the front of the spinner and ground away.
