Let's see your home-made spin testers...

[J. Cook]

Okay guys -- let's see some of your home made spin testers (not spine testers - spin testers).  Just wanted to see what some of you have come up with to check broadhead and nock alignment, straightness, etc.

a board and 4, 16 penny nails. two crossed at each end kept as close to the same height to each other as possible. about a foot long board.

From a thread last Feb, 2012:

 

I know this has been covered but this tool I made has helped me with getting very straight woodies. Checking the TG how-to's and searching here I got the roller tip. It just helped me one step more using mine as a truing checker (spin tester) and  a straightness checker.

I have several wood arrows; POC, Poplar, Douglas Fir, and some that I believe are hickory shafts (got'em in a trade).

I had a hard time straightening them and bought an ACE roller straightener. Great tool, but testing the shafts by rolling on the countertop was not very productive for me.

I also had a hard time truing field tips and broadheads.

In my quest to make a truing aid I also ended up with a straightening aid as well.

I took a 1x3 of good straight oak from the local hardware store and cut it to 19". I bought cabinet roller catches and used the roller half of the two I bought (make sure they roll...I had to open several packages to check for free rolling rollers).

Once I had the point truing tool I thought it would make a great way to see if an arrow was straight.

Using the tool I roll the shaft on the rollers and look at the gap between the wood base and the shaft. Especially if backlit you can easily see the gap. If the arrow is not straight you can see the wobble in the gap. Roll it to where the high spot is up and then roll it with the Ace roller straightener against the hard oak board. Check with a quick spin. Hit the high spots again if necessary.

So, an easy truing check tool and a arrow straightness checker in one. The Ace Roller helps tremendously with straightening.

   

   


You can see the gap with the help of using backlighting.

Modeled after Bub B's it also works well as a crester.

I never thought of using cabinet or closet door hardware, looks perfect!

Never needed one put it point down on a table and spin, look for nock wobble or broadhead wobble. It has never let me down. Shawn

Very clever.  I like it.

I also never used a spinner before last year and would just spin and adjust, spin and adjust, spin and adjust etc... But I seen a thread last year and made a simple crossed nail spinner/Broad head aligner and boy did it cut the time down!

Thank you guys. It is good to see soo many different designs.

As others mentioned you don't really need one but when you use one you will find they are really accurate and quick to align a point or broadhead.

For arrow straightness I spin them or use an old aluminum arrow straightener with the dial.
