    Union Graduate 1.5HP motor upgrade project

    I decided to treat myself to a clearance stock Schneider ATV12HU22M2 sensorless vector 2.2KW inverter, which should arrive tomorrow. I have no idea how the sensorless control works or how it compares with a drive with a sensor, although I presume sensorless will be at least slightly inferior. I...

    Cladding staircase

    The newels were 90mm square IIRC, so ended up around 125mm square . They actually look better proportioned with the cladding on. The oak is 6mm thick, so will tolerate the knocks it is bound to get.

    Cladding staircase

    I did exactly this 2 years ago, transforming a 1970s ranch style staircase to oak spindles, handrails and oak clad newels. I used engineered flooring for the cladding. took quite a bit of work, but looks pretty good now IMNSHO ;) Detail from above of the newel post cladding: Stringers were...

    Union Graduate 1.5HP motor upgrade project

    I have been doing a little reading up on vfd and as far as I can tell, if you use a 'vector' inverter, the torque at low revs is much higher than a 'non vector' type inverter. I am considering whether for my use, I would be better off replacing my non vector 1.5kw inverter/vfd with a vector type...

    Union Graduate 1.5HP motor upgrade project

    Does anyone know what the cage size of the original 3 phase motor is? I have seen a 'compact' 1.1KW motor which has a size 80 cage and given the ABB motor pictured above is a size 90 cage, I am hoping this compact motor is nearer the size of the original motor. Also are the original holes in the...

    One more question, where did you get the new stepped pulley and what was the specification of each of the pulleys? Many thanks

    Another option - I just mounted my vfd on the lamp bracket in place of the lamp. Lighting in my workshop is very good :)

    Was the cooling an issue in the end, or was everything OK? I ask because I am considering the same upgrade.

    I am considering the same upgrade. Were there any issues in the end with the cooling, or was it all OK? Cheers

    union graduate on castors?

    Do you raise the lathe on all of the castors together with a single pedal, or do you operate each castor individually? One if my concerns was that unless the whole machine is raised in one go, unnecessary stress would be placed on the connection between the lathe head and the bed or the bed and...

    union graduate on castors?

    At least for now, I have positioned the lathe reasonably conveniently. I will see how it goes and if OK in that position I will look to bolt it down. Rotating the bed would not work for me as I don't have the room for that. I will keep my thinking cap on though, just in case I do come up with a...
