I've had a play around using some walnut off cuts to make a bolt handle for a crosman 2250 build. Started by epoxying 2 bits of walnut and a ring of delrin to a threaded rod, then turning it down in the lathe. Not sure how it will turn out, as I use sandpaper on the wood, and the delrin will end up with a satin finish due to the sandpaper. Anyway we will wait and see. I will take more off the bolt as I still have to turn the threaded rod from 8mm down to about 4.5 mm. So I don't want the final finish done on it yet as I have to put it in the chuck, and so I can work out any marks that the chuck makes. Here's a couple of stages so far.   I'd put some linseed on it to see what it turns out like. It kinda shimmers in the light, and the photos don't pick that up.   |

With this, what I feared would happen did. I left plenty of meat on the wood so that I could put the wood in the chuck, turn down the metal, then turn off the chuck marks, but the wood was too soft and a slight load on the metal part made it slip. So I will turn the metal part before I put the wood on for the next one. On thing I have learnt with making stuff on the lathe is how important it is to get the order of operations correct. Back from holiday this week, so can start playing in the garage.

Two ideas to do that one. 1st can be dodgy but both things have done years ago. 1: Put two thin nuts (cut one in half and face both peices) on the very end of the thread. Lock them together just about end of shaft (bolt end) and turn the shaft from the nuts to the handel.( check balance at low speed) When that is done put in vise with soft Jaws and hand file the left threads off to die size. Then run die down end for bolt connecting thread. 2: You could also bore out A piece of metal or wood so the bolt handel knob is a snug fit and it's the same length as the knob. Then cut that in half length ways. The gap left from the saw width should allow it to act like clamp around in lathe chuck. You can file the edges more if space not enough. Second way safer buy far and useful for more. Think a hacksaw cut is 3mm. |
