New motor for Pillar drill?

Postby TobyT » 26 Feb 2021, 11:32

A few years ago I bought a Meddings floor standing pillar drill off ebay and proceeded to strip and repaint it. And then as with many things I get invovled with I ran out of time and it's mainly been sitting in bits waiting for re-assembly. Which I've been thinking about doing now the garage has started to get into double digits on occasion.
I did take the motor apart (A Gryphon Brooks which I think was original) and put new bearings on. But when I started to put it back together I realised the wiring is probably not up to snuff. I can't see how to easily re-wire it.

Is it possible to do this myself, or do I need to go to some strange backstreet finangler who can do this? If so how much is it likely to cost, and does anyone know one West/South Bristol?

Or will it just be easier to buy a new suitably sized device? The original didn't seem to have any form of capacitor and when I saw it run before I bought it it had to be started by spinning by hand.

Let's see if I can get pictures to work

You can quite easily get motors rewound, they'll re-do it all and test. My old firm used to get them done occasionally on relatively low value products. It's not significantly expensive. Don't know anyone Bristol way though. Have a Google. If you find one, they'll advise of its worth it.

Looks like you have enough connections there to make it reverse. The wiring doesn’t look all that bad, but I would get it meggered at the very least - a decent electrician should be able to do this.

Sorting out the configuration will be a combination of visually tracing the wires, eg you should see a couple going to a centrifugal switch, and using a multimeter to establish the location of start and run windings.

There’s no harm in tracing the wiring while you’re finding a sparky. Do you have a multimeter?

Motors of that age can often have perished insulation so probably worth getting someone to look at it. It needs High temperature insulated wire/sleeving and proper lacing cord which a rewind shop will have to hand.
It is important that the centrifugal switch is in good condition as these are not available as spares.

If you end up replacing the motor give consideration to a three phase motor and inverter combination as this will give continuously variable speed control which once you have used such a machine you will wonder how you ever did without it.

I have rewound a motor for my own needs and would not hesitate to do it again. I ẃas short of money and could not afford to have it done professionally so I did it myself following instructions from my uncle who rewound motors as a side income in the late 50-ies and 60-ies. At the first try it burned out again but my uncle told me what I had done wrong and the second time it worked.
However this is a rather time consuming job that requires a very systematic approach when you do it first time. You also need to get proper materials from somewhere.
In your case with a shortage of time I think you should have a professional rewind it for you.

Thanks all for the advice,

apologies for the delay in response, time is in short supply, so as suggested I will try and find some rewinding specialists and give them a call. Unfortunately the most likely option is a 30 minute drive away in a direction I rarely go, but I will dig and see if there is anywhere else.

I do have the centrifugal switch and pictures of where the wires went (somewhere, I know where they ought to be...)
