I got more wire, I thought I mentioned that on here but maybe I only mentioned it in a private email or 2.

I used a solid 1 inch diameter steel rod as Thane initially used, no laminations to remove, i could try drowning it in CRC/WD-40 or soap and water (but do not want to encourage rust) but I think cutting it is going to be the easiest solution.

Now I'm just putting off a big clean up of the garage I will need to do to regain some space before i can proceed, but I should have absolutely everything now besides of course the space.
Though I have not tested my Tach yet which consists of an IR led, a small led looking thing which is in fact a photo-transistor sensitive to the light from the former and a multimeter.

Okay, I ended up using the 1/8 thick steel pieces from Home Depot in various size to match the cups.

Let me know how your tach works out. I am using a bicycle pedometer (under $20), which is very  accurate at lower speeds, but when you get above 1000 the rpm range starts to jump. At 1500 the jump is about 15 rpms. Lately I've been reading about model airplane propeller optical tachs that are very good at higher speeds for around $20.

Oh, good info, thanks Larry!

note: actually too many turns isn't a real concern because due to the breakages I have the following ohm choices: 30, 120, 150, 450, 480, 600 all rounded slightly (smaller numbers happen to be closer to the core and ohm for ohm represent a greater number of turns)

A PICTURE IS WORTH A THOUSAND CONFESSIONS.

THIS ENTIRE THREAD IS ABOUT LENZLESS OPERATION - OR DID YOU SLEEP THROUGH THAT CLASS?

thanks for the wake up call, LOL
