I bought this little Harrison Vertical Milling Machine a couple of weeks ago, supposedly out of Pembrokeshire college when they axed off the practical engineering department. It appears to have very few miles on it as everything seems to operate smoothly with no discernable slop anywhere.
Done a little looking around on the forum and while there are a few posts on these they don't seem to be as common as the standalone horizontal or the combined horizontal/vertical machines. I just need to get it powered up properly, it runs off my 3-phase diesel generator fine (inconvenient for the mill, costs about £8 an hour to run! As well as having to run an extension lead from outside to the mill) but it really does not like running on an old Motorun Convertor (which is what the guy was running it off, his was much smaller, but mine is situated about 15m away from the mill which probably doesn't help), the motor makes hell of a racket and cuts out after a few seconds. I've got a DrivesDirect Digital Convertor but I'm not sure how much that will like running the main motor, feed motor, and suds pump at once though the combined power of all three is less than 2kw. DrivesDirect reckon it will run it but said I would be best changing the coils in the contactors for 240v ones and running them off a separate supply, the only issue with that is the contactors are long obsolete Danfoss contactors which the coils aren't replaceable, so it seems I'll have to replace the contactors with new ones fitted with 240v coils which will be a pain-in-the-neck exercise. Open to alternative suggestions on that.
One thing I've tried my best to find is a manual for the machine, I can get one from Lathes.co.uk, but paying £42 for a photocopy seems a bit excessive, I can find cheaper horizontal mill manuals but that doesn't help me much. I was wondering if anyone had a spare they would sell or a PDF? I may just have to open my wallet for the photocopy.
