Evening. Good progress made today. Carried on with the toolpost - trimmed it down to size and made use of the radius on the inside corner. Its also got a nice shoulder on the upper part of the 'L' which fits nicely onto the turret. Heres the thing assembled so far - Just need to work on the tool height and deciding what tooling to use. I have some nice HSS 8x8 which would work well on this. Best. Nick |

Evening, I was busy last night and managed to take a few pictures this afternoon - First off was another try at the toolpost. The old one would have worked with a carbide tip but I couldnt quickly figure out how to cut the 80 degree pocket for the tool. I started again and I had in mind holding an 8x8 HSS tool. The script was the same, machine the bottom part of the L to fit the slot in the turret and mill out a slot to hold the HSS - and I was pleased with this and really just needed to make the leverage bar. Fitted - Looks like the first ball I will make is going to go on the end of the bar. A few jobs yet to do before I can try a few test cuts. The retaining bolt needs to be glued in and its clearance checked against the cross slide as it feels like its undoing itself. Also the mounting bolts need to be turned down a bit or made shorter so I can get a full swing with the toolpost moved back. I also need to grind the tip to cut balls. All in all it feels like im getting somewhere. Nick |
