Re: Back plate

+1 for Dennis’s suggestion of boring the internal thread to fit.

Also, from prior experience, using weight lifting weights often gets you into working with the poorest, low grade materials you’ll ever work with. ?Also weight often have sand intrusion and impurities, due to cheap and dirty foundry practices. ?Profit margin is based on the lowest priced production methods and the cheapest grade materials available.?

Much better to go buy a proper, high grade iron backing plate, then face it and bore it to your requirement.?

Just my 2 cents worth...

I've not seen one anywhere with the right threads.

Best I've found is either a blank or one with a smaller hole that could be bored out and threaded.

Steve Jordan on Youtube suggests using an exercise weight as a source for a blank.? I don't know whether that's a good idea or not.



You can also get taps of that size, but IIRC, Dennis said the spindle thread is a little off from 1-1/4x12 and it's best to cut it to fit.
