Convert Wood Lathe from hand held tooling

[Wobblybootie]

I get what you mean ...and that is a possibility. I was looking at the bowl problem from the the direction of mounting the blank and machining in one go, if I mounted the blank then proceeded to mill the outside first then rechucked it as I would under normal circumstances, then milled the inside to finish, problem solved. I still may be better off mounting the router on a rotary table on the cross slide ... I am assuming that I would continue to keep the blank turning in the standard direction to get the cutter into a 'reversed' or concave bowl lip. I had fallen into my normal trap of overcomplicating things...

Hi,
Yes think you might need the rotary table if using a normal router,something like this may work without because of the small body http://www.mycncuk.com/forums/showth...ight=brushless ,but it does mean your in for a lot of work with the total conversion,the good thing about using a router/spindle is the speed will do all the work,so you could drive your lathe chuck very slow,maybe with a stepper motor,the motor would run continually for turning work and then index round for your fluting,barley twists or any holes you need round the circumference.

Sorry to piss on your chips but from the looks of that machine, nice as it is, it's not a real candidate for a CNC conversion.

You would probably be a lot better off selling it or using it as a second op machine and starting with a clean sheet of paper.
What you want to do has been done before in various stages, simple linear rails for the bed and cross slide and a double drive system for the head as Steve says, motor to spin at speed for turning and stepped geared drive for barley twists etc.

Well hope you get it sorted mate,so you can get back to making a living.
