A Gorton is to a BP what a Chev is to a Rolls Royce. They are an
excellent machine. Do not be discouraged by comments that have little
merit.

I think you reversed that. Bridgeports certainly are NOT Rolls-Royce
caliber!

OTOH, as rigid as the Gortons have reputations for being, I'd want a
tilt-head machine for my 'second-ops' position. My mill is a rigid-ram
machine, and there are things it would be nice to be able to do without
all the fuss and bother of sine plates and complex fixturing.

My I-22 has never had the head swung. And I do a fair amount of
machining.

I hang around industrial machine shops for a living..and in the 16 or
so years Ive been repairing machines..I think..think I remember seeing
one swung or tilted.

Ayup...I do remember (1).

A great deal depends on the shop in which a machine is used. Some may
dedicate given machines to altering head, ram and turret positions. In my
shop, there was but one machine at any one time---it served all purposes.

I've altered all of these setting time and again, and continue to do so even
in retirement. They allow dealing with pieces that otherwise wouldn't be
possible.

Make no mistake---the features of a BP mill are exceedingly
valuable---that's the reason they've been so damned successful. It
certainly isn't because of their high quality. In fact, they aren't even
scraped. They are a very nice machine for the money, but they are not of
high quality. Never have been.

Not scraped, you say?

Please---I'm not open to discussion on this particular subject. Flaking,
which has been provided for aesthetics and oil control, *is not scraping*.
The only portion of a BP that is scraped is the knuckle on which the head
mounts. All other way surfaces are ground.

Look closely. They are ground, so please don't argue. (Not aimed at you,
Gunner. I think you know it, too!)

Indeed. I fix em when they break.
