Geez, I hate it when this happens, measure, measure, make things all neat and nice and then somebody changes the rules. I grabbed another pencil, stuck it into the gauge and went “hmmm, this seems pretty loose”, cranked down on the screw and crack! Copious amounts of bad language ensued. So I did what I should have done in the first place, which was to extend the pinch slot past the pencil, making a longer hinge. But no, the slot closed and still the pencil wasn’t held very tight. Grrrrr. Get the calipers and do a pencil hunt – Dixon #2’s are just bigger than Office Depot #2’s (by 0.020”, not very much but maple doesn’t like to bend that much over a short distance). Another head scratcher, probably the best idea is to have sleeves for different pencils, then I could also use mechanical pencils.
- 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.
