Hello group!

I've been looking for a CNC victim mill for a few years and came
across a Bridgeport on Craigslist for 650 near Seattle. I'm going to
go look at it tomorrow. What should I be looking for?
I've only worked on lathes, mills are a new to me. It seems like they
might have different kinds of problems.

It has hydraulic cylinders in place of screws and handwheels for the X
and Y travel.

Also wondering about moving the thing.

Thanks in advance for any tips/advice.

Sounds like a Moog Hydrapoint.
If so they are more trouble to convert than a manaul mill by the time you have bought ball screws and maschined up for mountings.

I'd seriously keep looking.

That also seems a little high for a Hydrapoint. They were selling for
around $400 at auction four or five years ago. I guess scrap prices
have gone up.

If you check out the practical machinist board in the for sale section,
there's a fellow in California that has a BTC-1 he wants to sell. I
think he'd take any reasonable offer (i.e. anything more than scrap).
That's a pretty decent machine as-is, but you can always retrofit if
you want.

Comes with a complete set of manuals and an assortment of toolholders.
If you buy it, you can lend me the manuals for copying :-) And if you
retrofit, you can sell me the old controls, so it's a no-lose deal :-)

No financial interest, but I have been trying to get him to scrap it
so I can get the manuals and controls :-) It's too far for me to
ship the whole machine.

If you're interested, drop me a note and I'll send you his e-mail.

If everything is working, then just having a manual mill would be a
great addition to one's shop.

On a manual mill, one moved the table into the center then snugs the
lock ever so slightly, then runs the the table to the end. if it
binds before it reaches the end, the table has worn. the closer to
the end, the less wear.

If you have the room for two machines, it is a good price.

If you want a more CNC ready machine, look for a Series II CNC machine.

A couple years ago the strategety was to phone around to all the
machine shops to see if anyone has one. At one time, they were
getting rid of them for machining centers.

IF you have not figured a budget for the conversion, get prices for
the whole ball screw kit and the whole stepper/power supply side.

for a Series II, you probably only need the power supply, so your
purchase price would be the value of a manual plus ball screws.
Although, some on here said that the Series II might actually sell for
less than a manual if the electronics are shot.

Sir,

You should get in contact with Jim Glass

www-dot-outbackmachineshop-dot-com

He did a Series 2 Bridgeport.

Jack C.

Thanks for the info. I'll pass on the hydraulic series-1 and wait to
find a mill with broken or obsolete controls.

That one is Orange County CA seems like a great deal with the
electronic positioners/motors in place already. Npt sure how much
shipping or truck rental usually runs, but I'm afraid getting the
thing to Seattle would be too much $$. One should come up around here
sooner or later.

Thanks again for the advice!

Cross town moving is about $250.00 here in So. Cal. From So. Cal. to
Seattle will be way more obviously. You can get qoutes by calling the
800 numbers on many of the freight companies.

If you are interested in my series one conversion saga it is at:



In that same forum there are 3 - 4 other actually better conversion
projects. It's the Bridgeport and Hardinge forum. Sort by views (count
of views) to have them come to the top of the list.
