John, sorry for the temp hijacking of this thread.
You posted a link on the NCRS site regarding overheating. That link in your post has a virus. A bad one. As soon as I clicked the link. My anti virus software went off like crazy.. I couldnt log onto the NCRS site right away (Forgot my password).. So I thought I would get you here.
You may want to pull that link and investigate your computer. My anti virus software caught it.
If anyone gets a flag? Do a forced shutdown imediately.
DO NOT CLICK OR EXIT ANY BOXES.
FORCED SHUTDOWN ONLY.

Generator Tach?
Ray,
I replaced my bushing as you describe and the chatter is gone, at least while I am turning it with my drill. I still need to calibrate it, my drill speed is supposed to be 1200 RPM which would mean my tach needs to show 2400. I can't adjust it to get it that high, my next step is to verify that my drill is actually turning 1200, we have some industrial tachometers at work that I can use to do that.
Thanks,
Brian

drive tachs show cable speed. 1200 RPM shows 1200 RPM on
the tach.

Swap meet tach
People buy old tachs at swap meets and don't know what
they are buying. A distributor tach is usually stamped on the
outside (tach shows twice cable speed). I have not seen
a generator drive tach that was stamped. However, I have
not seen that many.

Does this same ratio hold true for midyears?

I'm not sure if all drills are like this but it is worth checking out.
Thanks for the help,
Brian
