Re: Bearing Fits?

If I buy a new bearing and the dimensions don't match the ones in the manufacturer's catalog it's going back.

I've only read part of the chapter on filing but I'm hooked. That book is great. Here is a link to a pdf:

Re: pulley size, variable speed

> The motor pulley has 2" 6',7' and 8", the upper has 10,8,7,6. This is not clear. Normally the motor would have a single small pulley driving a single large pulley on the counter shaft. The counter shaft would then have three pulleys opposite three complementary pulleys on the spindle. If you can g...

Re: I want to make new lathe feed dials

Sorry I was unclear. I was thinking of the teeth on the saw as divisions on the saw.

To be clearer (I hope) using the 100 tooth saw blade as an indexer put a mark on the new dial for every four teeth on the saw blade. You will then have marked every fifth desired dial division.

4 teeth on your 100 tooth blade is 5 divisions on your dial. Mark every 5th division using the 100 tooth blade and then interpolate.
Every *4th* division.

Re: Metal Working

I may make myself one of those turf tools. I have some silage forks that I really don't have a use for.

I would do something crazy like check the run out in the bearings, put a straight edge on the ways, check the gearing, clutch and shift forks, take a look at the lead screws, check back lash. Then decide if it is worth bringing home.
That's basically what I suggested he do.
