My Camera is dead and my phone gives me a "DSP Error" when I try and take a picture.
If all you need are the speeds, I will try and give you that information:
The Heavy 10 has a two speed countershaft. (2 groove motor pulley)
The low speed is 300 rpm, The high speed is 579 rpm
The spindle speeds are as follows:
300 rpm countershaft 700 434 277 back gear 129 79 50
579 rpm countershaft 1357 837 535 back gear should not be used with high speed
I have a VFD on my lathe so I can vary the speeds. The plate on the lathe (1968 Heavy 10) says that the maximum spindle speed is 1400 when using power feed and 250 when using back gears. I looked on Ebay and found a tachometer that uses a reflective strip. It was shipped from Hong Kong and cost me somewhere around 10 or 11 bucks including shipping! Arrived in 11 or 12 days! It works great. just point at the reflective strip and push the button and read the rpm. It works up to about 2 ft away. I put 3/8 inch squares of the tape on the motor pulley and my outboard spider on the spindle. I have had this for a few months so now I have the reflective strips on just about everything that moves. Have you ever wondered how many rpms the rollers on your garage door turn when the door is moving? I don't anymore.

I guess I bought the same one or similar Earl. Mine lasted till I tried to use it the third time in about that many months. Seems to be a problem in the push button. Can't find the original supplier on eBay. It's a DT-2234C+ and it did work great when it worked. Only cost $5 per use +/-.
Is this it? http://www.kerncoinstr.com/lasertach.htm
I'd like to get one of these. I think this would help a newbie like me.
