Re: [CAD_CAM_EDM_DRO] Re: My Logan Clunker & leadscrew compensation

Hello Jon,
As far as I have experience with rebuilding machines (last 11 years)
you are right it is cheaper to look for a good second hand than rebuild
a small machine. Last month I rebuilt a sharpening machine to selfcost of 1300$
and the new machine is 2200$.
It is worth it on larger production machines in good general shape or
rare dimentions where the base is of good quality.
All the rest often becomes a waist of time and money.
Good Luck
Sven Peter
