Science

HUH?? Are you even speaking English? There's no place to sit a frequency meter on my wall phone. You must be from another planet or something way off in the future.

You are me from 4 months ago. Bit the bullet and bought a smart phone. It's come in handy for more than Facebook and talking.

When trying to figure out the RPM's of Charlene, my 1956 Farmall 450, I was told to get a photo tachometer. They're on Ebay under $10.00. They come with magnetic tape you put a small piece on the flywheel and then point the Tach at the tape while running and you get your RPM's.
Just a thought.

What ETAModel said...
Here is a really handy tach I got on Amazon which works on any rotating surface. Just stick a small piece of reflective tape (lot's of it comes with unit) on the front pulley where you can see it when the engine is running. Point the laser, read the RPM. Not to mention it comes with a nice zipper bag to keep it in.... Chap

Hmm, I wonder how they did all this stuff back in 1931. [smiley face]

Exchanged the old battery for a brand new one today. Took a reading on it before I put it in the car and it's measuring 6 volts. Stick it in the car and it fires right up like it's nobody business. I mean you can instantly feel the difference as soon as you push the starter, very strong turn over. Now if it would just stay that way I'd be happy. I gotta take some more measurements but ran out of time today, but "I'll be back".

With any luck that battery should last you about 10 years. Have fun!
