Re: [CAD_CAM_EDM_DRO] Gorton mill

Jeff,
If you were to pay $3500.00 for a Bridgeport BOSS, including shipping to
your door, it would be cheaper than retro fitting the free Gorton. The BOSS
already has steppers, power supplies, ball screws and some at that price
will still work as is.
Darrell
PS you can often get a BOSS much cheaper than $3500.00 delivered.
