Been a while since I have posted here, so I thought I would share the drawbars that I made for my Kondia FV-1 mill as well as the hammer.
Given that I buy most of my tooling OS, I have ended up with two different threads on my tooling: 1/2-13 for the US stuff and M12x1.75 for the metric stuff. Both are made from 4140, using ground and polished 1/2" pinned into ø30mm stock that was turned and milled to for the hex. The coloured grooves are so I don't mix them up!
The hammer uses a 1/2" drive 19mm socked and a weird brass pipe fitting that I found. It has a 1-14 threaded end and once screwed on, I filled it with lead. I did contemplate simply knurling the handle but I decided to steel someones idea of making wooden scales. The wood is recycled Jarrah (eucalyptus marginata) and I deliberately cut the wood looking for some imperfections. Oiled with Ballistol and once that soaked in it got a polish with some locally made gun stock polish which leave a nice non-slip finish.
I'm really happy with these and they are much nicer to use than to two crappy ones I had been using (one came with the mill). I also added a thrust washer which sits in the top of the housing and it works very well
