Thread: myford motor

With most of the single phase AC motors one has to change the polarity on any one of either the running winding or the starting winding. This is done by means of either a reversing switch or 2 contactors with an interlock. Make sure the centrifugal operated starting switch is operating correctly.

We seem to have the same "shortages" of bugs and birds in South Africa. I am wondering how much is contributed by genetically modified plants.

The engineering drawing for late 30's Rudge cam followers give the heat treatment spec as

HT 7/04/Pc HT16

Can any knowledgeable person explain this is simple terms, please.

I suspect the numbers represent another factory engineering drawing or heat treating process.

Thread: Dovetail cutters
08/12/2014 08:58:00

The Russians still use 55 degrees on their machine tools. Other than that basically all small machine tools use 60 degree dove tails and the larger machines use various other systems, from square slides to in house bearing designs. Round bars used be used on older type small machine tools like the older version of the Emco unimat.

Hi guys, is there no heat treatment that will soften the titanium?

Peter,I had success with exactly the same repair. I used lard (pig's fat) as a lubricant and fed all three the taps from a set of hand taps through from the bottom (back side) of the work piece . It worked like a charm.

I have already built 2 of the clutches, one for me and one for my son. They both work perfectly. I had to change the spring, used one a bit harder.
