Al, Flycutter grinding. Think of it set up in the lathe as cutting from the inside to outside. That gives you a good idea of the rake angle and the necessary clearance angles. Radius the point a little like any lathe cutting tool and you should be OK to go! Hope that helps. Ian |

Hi Al.NICE.A lot of that vibration may be due to the belt.You might try a twist link v belt and mabe a cast iron pulley. Crab |
| Pete.:
I think if you lightened the cross-slide block below the slot for the brass slider and thinned it either side of the pinch bolt, and used a hollow tube instead of solid for the ram, you'd see a huge difference. You could also cut out the crankshaft webs either side of the pin to make it a counterbalance. |
| CallMeAl:
Crab: I agree with you on the belt. The belt is tensioned by the weight of the motor. If I push down on the motor a little it smooth out the vibration somewhat. Twist link belts are expensive, so I will live with a little vibration. ::) Pete: Your suggestion of lightening up the reciprocating weight would probably help, but I'm to lazy to do it. Thanks for the ideas. |

Probably one easy anti vibration measure would be to drill into the drive/fly wheel rim (or the face) each side of the pin that connects to the brass block - or mill a slot in it if there is room. As it is, the weight of the pin is throwing it out of balance. So countering that with a bit of metal removal would help. It would be worth running the drive/ flywheel disconnected first to see just how much vibration it generates by itself. |
