Re: new machinest and CNC

Hi Jay,

Interesting day,
are you out Texas way ?

You will also find the 7x10 lathes can be fittted by going over to
the TurboCNC list. Dave K, the originator of the TurboCNC program
did it for his HF lathe.

This is a mechanical adventure. you will need to make some parts, but
when you think about it, all you need are the mounting plates and
motors.

I'd recomend you visit the 7x10 group, but I already said hello to
you over there.

You mentioned small parts, the HF/Griz 7x10 lathes are pretty rugged
compared to some of the hobyiest lathes, and may be less expensive.
They may also be a better platform, determine your needs then find
the machines that suit them.

Dave
