Posted some pics of a spine/FOC tester I was building a few weeks ago, thought I would post some finished pic's. (http://i567.photobucket.com/albums/ss115/earljeff/spinetester2003.jpg)

It looks very nice to me! Would like to see the FOC part in action. Hap

FOC in action Glynn nothing more than a balance point a tape measure and the math formula.
Earl, how do you zero out the dial indicator before lowering your weight?
That is slick! Hap
Old York - The bezel on the gauge rotates and then you can lock it into position.
Thanks Tom. It has to be adjustable for different dia. Arrows
I know the bezel can rotate, but one still needs to get the plunger
dial under the shaft with no pre-load :banghead:
I'll re-phrase my question - Earl, how is your jig adjustable for different diameter arrows?
How do you move the dial indicator up and down?
now that looks awesome!
Old York, on mine, I made my right post adjustable up/down/in/out to help zero everything up. Course, mine's not slick built like Earl's for sure. ART
Hi Art! HA! I know what you mean...that's
a nice piece of work Earl did with the copper piping and fittings.
Least that's what it looks like to me. Pretty dang clever he is :D
Mine looks like something from the Red Green School of Engineering,
but she's accurate. I learned how to null out the dial indicator influence,
thanks to your support!
I WOULD LIKE TO TAKE CREDIT FOR THE GREAT PIPE FITTING BUT IT WAS PART OF A OLD SCOOTER MY BOY DISGARDED, AT LEAST I HOPE HE DID. :confused:
