There's a horizontal mill on CL that looks great, and comes with a bunch of tooling, which is good, because it can cost more than a used mill. It's pretty affordable $550, and not too big to move with coordinated effort, about 1200 lbs I think.

If anyone can contribute funds that would be great, it's not the best timing for me, but I'm will to lead the funding. We'd also need:
  • to get 3 Phase power running ASAP. The seller doesn't have it under power, but will guarantee it runs for a week, so we'd need to power it up right away and make sure the motor is good etc.
  • Having a 1 ton engine lift or similar to pick it up out of a pickup and get it onto the dock
  • Alternately If anyone knows if Jepsen has a forklift and could be hired for a few minutes work, that would be great too.

So if you can help fund it let me know.
If you have an engine lift we could barrow, or know where to barrow one, that would be huge.

Lastly, a show of interest would be good. It's not a huge tool that takes up a ton of space, and I think it would be very useful for numerous projects, but that's just my opinion. I'd like to hear from others. Also I won't be in Weds, so if someone can spread the word Weds Night that would be great, I know not everyone reads the forums.

I'm waiting to hear back from the seller, it could happen this week potentially if there's interest.

UPDATE - I believe this is the same model, there are much better pictures here.

There are dozens of good quality horizontals on ebay for about 30-50 cents a pound.

It's a pretty limited type of machine. You can't drill holes with it or mill a t-slot. You can't add servo motors to it and cut out profiles. It shines on a few specialized uses, like making custom press brake dies.

For a first mill, the Bridgeport style vertical is pretty hard to beat. You get 2 axes of rotation in the head, plus power downfeed for nice smooth finishes while boring. Adding CNC is pretty easy. Heaps of cheap used parts readily available.

Yep, but as they tend to weigh 1000 - 4000 lbs so shipping is more than the mill. This is local, is .45c a pound and has tooling up the whazoo.

I'm not sure why I can't drill holes, or mill t-slots with a Cat40 holder and an endmill, but as to cutting out profiles, that's true, it would be painful, thus the vertical head option to pursue, and CNCing if desired, but probably not for this one, it has auto x feed already with it's built in pneumatics. You can do nice work with tubing, sloting / keyways, slitting stock into smaller pieces, making big stuff flat and square in a hurry in addition to what's mentioned above.

Yeah these would potentially be nicer, but they are projects, as opposed to working systems, and we've got a fair number of projects piling up. They are also quite a bit bigger, and more expensive, but if your buying and moving them, I'll be happy to help :) Ditto for helping to bring your mill in!

Thanks for the input Jim.
So far no response from the seller on this one.

I guess my point in mentioning the abundance of low cost horizontals on ebay was simply to point out that the reason they can be had for so little is that they aren't all that versatile.

That said, an ingenious and obsessed individual such as you or me could probably figure out how to mount the work on a "tombstone", adapt a collet to the spindle to mount an endmill, and add a camera so you could see what's going on at the bit on a display screen from the front of the machine...

The Bridgeport looks like a diamond in the rough. I'd recommend at least looking at that one.

Yeah, unfortunately my understanding on that one is that MDI was a record / playback type CNC. An operator did the first part correctly and the machine could playback the sequence. Not a big deal if you use a new controller, but BP was very frugal and decided that one drive channel was enough, so it only has one, thus you can only move one axis at a time, no contouring, no circles etc. The servos could be kept, but you'd need 3 new drives, so thats $400, plus encoders potentially.

HoffHilk had a half dozen Interacts in one auction a few months ago, I think that was the golden opportunity to score a cheap CNC. Ah well.

Actually, if the iron is in good shape $1000 is a pretty good price for a manual Bridgeport.

I'm personally more interested in getting a manual mill than a CNC mill, at least for a first mill. A used Bridgeport knee mill with even barebones tooling would really expand our abilities.

CNC is awesome, but it requires an understanding of the basic underlying concepts, which are best learned on a good old fashioned manual mill.

I'm definitely interested in contributing to the purchase of a Bridgeport-style manual mill. Something pretty big would be better than a smaller, flexier type. If you're going to get a milling machine, you might as well go for a little overkill rather than be disappointed by limitations of a lighter machine.

I appreciate the learn manual first approach, and I'm not opposed to it. There is a populace that wants to produce parts, not become machinists, that's not me, but I think the users and uses is something to consider. I've put the horizontal aside for now.

Size wise I go back and forth, I'd love something small enough that it could go in my basement, without removing the house first, if for whatever reason that's what I needed to do. For a HF specific machine, I think big would be great, but I'd like to know if we might move before committing to something that can't be moved with a pickup, or lifted with a pallet jack. Compromise size wise is a Clausing 8520 size machine (think 3/4 sized BridgePort maybe 700 lbs) There's one on CL and one in an upcoming auction. The work envelope is 5 x 15 or so, so its comparable to a HF mini mill or RongFu Bench top, but better made, and should be as or more accurate if it's been taken care of.

There are giant mills that aren't hugely expensive out there too, saw a 5HP K&T that would dwarf a Brideport and be much rigid and powerful, its in IL though, so shipping would be spendy and we couldn't move it once inside the HF (5000+ pounds)

I'm glad we've got the conversation going, if your interested in milling, and or making metal parts chime in.

ooh this looks interesting, a short drive into WI

http://www.hoffonlineauctions.net/cgi-b ... ff77/320/3

Looks like it's in nice shape, 5HP Vertical and Horizontal, under 3000 lbs, more beef and power than a BP plus bonus horizontal milling, and extra travel, what's not to love? (Oh and they seem to have a pretty good reputation online)
It's an auction, so tough to know the price, it uses standard (#40) tooling, but doesn't appear to come with any. Thoughts?
