Hi there. I've just joined this forum and I am hoping that someone can help me out about the electrical circuit for the M300 (UK). The electrics in mine are...
Sounds like it may have been set up to run with an inverter at some point and then quickly converted back to 3-phase, perhaps for sale. The no-volt circuits...
Niel Thanks for the reply. I may have set you off on a wild goose chase. I looked at the circuit for an hour or so before posting, but still didn't spot the...

Would it be possiable to make a lever start switch for the carriage? possiable location a square or hex rod under the carriage tied into main spindle...
I think I've sorted the problem. There is a different layout of the bits in the electrical cabinet consequent on adding the fuses. The problem was the no-volts...

I have an L6 with taper attachment. It may be different than yours. The lead screw telescopes into and out of the front hand dial assembly on a set of mating...
Lee. Thank you for your reply. By the looks of it, the basic mechanism is the same. The difference is that I can't find any clamping screws, either on the...
Jeff I have thought about making a block with a rib that would fit tightly in the guide bar slot and lock into the casting, the one on the back of the saddle,...
Hi again Lee I'm sorry for the delay in answering, but the hard disk on my computer failed and had to be replaced. However, I now have the answer to my problem...
Hello im in the san antonio texas area and im in need of a lathe bed reground for a m250 or a replacement if anybody has parts - i bought the lathe for 1500...
Commerce grinding here in the DFW metroplex (Dallas) can do it for you. Several members in our local metal workers club have had it done to their lathes. It...
Hi, I have a Harrison M300 its about 15 years old. It is 3 phase and I want to convert it to single phase. How do i do this? I know machine mart sell motors...
I have a Harrison AA and the motor is 3-phase. I run it off of single phase with a phase convertor.. There are plenty of web articles on phase convertors. You...
Dan, Thanks for your reply. I have looked into a phase converter. Could I not just get a 3hp single phase motor and mount it in the place of the orogional? Do...
Not aware if anyone esle has done this, but you have to remember you couldnt use lathe onboard overload circuitry, have to rewire start stop & cut out switches...
I have an M300 and had to make a similar decision. I would forget the change to single phase unless you are willing to accept degraded surface finish and ...
VFD is the ticket and they can be had used for $50 to $200. Soft start, brake, and variable speed capability included. Size and weight is much better than a...
I have an M300 thinking of running it on a VFD. The motor on the lathe is 3ph 415volt. I want to run it from single ph 240 volt. According to the motor plate...
Have a look under the connection plate and see what terminals are available. If there are six wires terminating in the box then it should be just a matter of...
Thanks Neil for your help. If I can I would like to wire the motor to delta this will enable me to buy a cheaper VFD. I have looked across the net but canot...
Matt, I very much doubt you'll need to rewire your motor. Virtually all motors since the sixties have had the six wires (the start and end wires for the three...
Unfortunately I don't think it's as simple as that. There are 4 areas that need to be resolved: 1) As indicated previously, the main motor is 415V – but also...
Hi guys (and Neil especially-thank you for your help). Since I no longer have a Harrison lathe, I have no place here. My damaged M300 was bought by the...
