Anyone know how to make a home made spine checking tool and how to go about making one?

I have one that uses a dial indicator that was very simple to make. Send me an e-mail or PM and I'll send you a pic.  Basically it's a board with two uprights, 28" apart and the dial indicator in the middle, and with a 2# weight suppended in the middle the deflection is measured in thousanths(.00) and compared with a chart that gives the spine weight.

The website you are talking about is:  http://www.jamesmhill.com/spine_tester.html
   I'll have to scan ta pic of the one Art Butner made. It is simular to Hill's but done with more wood and easier for me to make. I'll get it scanned in a bit and post a pic.  I'll also scan and post the deflection chart that goes with it.      Pat

Someone send me an e-mail address so I can e-mail this to you. I can't get it to come up as an attachment.   Pat   marciaandpat@citcom.net

Well, I sure can't post decent pics. Maybe the one I sent to Justin came out better.    Pat

That spiner has wheels on the end where the arrow sets so it should double as a arrow spinner or a hand spun crester.  Save us all a lot of space. Justin

Justin, I got my roller bearings from a skateboard shop for only a few dollars. They work very well for this application.   Pat

Brandon, Those 2" will make a heck of a differance. Test a arrow with a known spine and adjust your spine chart to that. I'm not an expert on this. I just go by what was told to me.   Pat
