Hey all,
I'm working on building a spine tester from plans from 2Jays link here:
http://www.bambooarrow.com/tester.html I have printed the dial and glued it onto a backing board. Now I'm ready to follow the directions below, but I'm not following them.
2. Drill two holes opposite one another around the rim. Be sure they are the right size to epoxy your spokes into. Install the spokes into these holes. Don't trim them yet. Be sure not to plug up the axle-hole.
3. Bolt the needle-hub through the hole in "Line A". Make a 90?bend outwards in the short spoke at the other end of "Line A". Be as accurate as possible. THIS LENGTH IS MOST IMPORTANT MEASUREMENT ON THE WHOLE DERN THING!!
3. Remove the hub and put a washer on the machine screw, install the hub to it, another washer, and a self locking nut. Tighten the nut so that the hub spins freely but has a minimum of side-play.
4, Put the axle through the hole in the dial and mark where you want to cut the indicator end of the needle. Cut and shape it to a rounded point.
5. Now locate and make the bend on the other end od the needle assembly. Measure "Line A" on the dial. Whether you enlarged the dial or not, this line establishes the correct ratio. It is important that the length of this line "A" is the distance from the center of the axle-hole to the bend.
6. Then install another washer, the dial, another washer and another self locking nut. Here again, tighten the nut so that the dial spins freely but has a minimum of side-play.
My question is has anyone built this tester that has some pics, I'm thinking that a picture or 2 would help me greatly with this.
Thx.
