After hunting around the auctions, I have managed to pick myself up a 240V Hafco Metal Master HM-50 milling machine for $2500.00. My plan is to first learn some basics before I convert it to a CNC.



The Mill also came with a 4" 3 jaw chuck, two sets (metric/imperial) of slot cutters and end mills, large set of clamps, a face mill, 8" rotary vice and mill vice, drill chuck with collets (cheap one I have been informed) and 3 other arbors + a few other bits.

and a 240V Hafco Metal Master AL 960-B digital lathe. Larger than I was looking for, but with the near new condition and again for $2500.00, I would have been a fool not to get it. Very happy with the purchase.



The lathe came with 3 and 4 jaw 6" (I think) chucks, some arbors, two center guides, and a few cutting tools. There was also a small all steel bench with a 6" vice mounted on it, I cut the legs down on it today and added some large rubber caster wheels to it today.

To get both machine's home, I also purchased a large all steel tandem trailer that was also at the auction. The trailer came with steel ramps and a large frame for supporting glass or alloy door/window frames. I currently have the Mill and trailer still stored at a friends place, but once the mill comes off (probably a couple of weeks time), I will put the trailer up for sale again if anyone is interested.

I come from Rye on the Mornington Peninsula and am looking for the following if anyone can help;

(1) Tafe or similar course suitable for a beginner, needs to be on or close to, the Mornington Peninsula.

(2)Any hobby machinists on the Mornington Peninsula that are interested in meeting.

I have also just purchased an electric kiln so I can try my hand at casting alloy possibly bronze. Again, interested in meeting anyone down this way for some advise or to just meet.

Cheers
Eddie

G'day Bernie and thanks for the reply, I will definitely send you a PM. I know very little about machining full stop and EDM has had me wondering just how it works. I saw your other post, looking for a machine for EDM, only saw a couple of machines marked as edm, go in a recent auction. I will keep my eyes open for you (would help if I actually new just what you are after).

What type of machine did you convert and are using now?

if you don't mind sharing, what auctions did you pick em up at?

I didn’t take any measurements, just made it up as I went
The steppers and drivers I got form here. 12 N·m (1700 oz·in) 3-Axis Stepper Motor CNC Kit :: Large Stepper Kits :: CNC :: Welcome to Ocean Controls

I think I got the ball screws from eBay
