homemade $1.25 spine tester

(1/3) > >>

Grunt:
After seeing the $170 dollar price tag on spine testers and getting 500 bamboo shafts I made my own spine tester. I used the 26" across and the 2lb weight so I could use known spine shafts to mark my scale. All I want is to get into the ballpark with this little tool. Hopefully I will learn to spine by feel. I learned one thing right off. If you have 3 or 4 foot boo shafts you can change the spine by moving the shaft laterally back and forth across the rests. Larger diameter stiffer spine, small weaker spine.

     Should work just Fine...you friggin Redneck......... ;D......... ;)......... Just jealous I didn't come up with that Idea........ :P

Justin Snyder:
It should work fine. If you wanted to get a $10 dial caliper to put under the shaft and measure the deflection exactly, you would have a precision spine tester that matches what many other guys around here have.

 ;D Hello grunt I like your spine tester alot,but I got one question for about that cane arrow,is the arrow you have in the picture still green? Cause if it is than you wont have a true spine. It looks alittle green to me.It should be tan to brown. Just curious ,not complaning.
