10" GMF Grinder NOS Wiring Issue
Hello from Canada! This is my 1st post on WWF.
Recently I acquired a NOS 10" GMF Grinder and pedestal to suit. It had been owned by an elderly farmer and evidently has never been wired up. So the stones are brand new. It is a 240v 3 phase unit (at my shop 1 hour west of Toronto) and I need assistance to it wire up. Weighs about 100lbs and looks similar to the 8" GMF pictured in the older threads.
Absolutely a qualified electrician will reveiw matters beforehand as I am duly cautioned by the other threads on GMF and matters electrical. Power can kill and I'm not wishing to go there.
There are 2 wheels and a central 2 position switch which I believe controld each wheel individually. Underneath 3 wires come out from the grinder...ALL YELLOW. They are connected to a small white ceramic block and thence to the switch and the motor or 'cap'.
From that terminal block there are 3 cloth covered wires going to the functions of the grinder. Q: should these older style wires be replaced/ they appear in good condition.
How to determine which of the 3 yellow wires are to be connected? Should the plug be a 3 pole 4 wire or a 2 pole 3 wire piece. My shop has 240 outlets that were set up and used for a 240v welder. They are 3 prong style...one U shaped and 2 flat vertical prongs.
What cable wire to use...10-3 seems the likely choice?
And finally how much is this grinder worth...it will certainly outlast me!
Should I exchange one wheel for a 12' buffing wheel will any imbalance problems arise?
Thanks in advance.
Colm
All assistance appreciated.
