Title: Homemade spin tester
Post by: Cavscout9753 on May 04, 2014, 08:46:00 PM
So I finally got around to making an arrow spin tester. I don't know much about photobucket, but it isn't that original. I used a couple 2 x 4 pieces, attached at a right angle, then melted some heat shrink tubing around 4 machine screws (2 separate cradles). The only thing that I added to the pre-existing design was I added a small bungee style cord that hooks over top of the arrow to apply a slight yet steady downward pressure to the arrow as I spin it.
I have to say I was pretty impressed. I always spin-tested my glued on tips on a counter top. Ones I thought spun well proved to be a little off. Granted, some (many) folks are better spinners than me, but I thought they were better than they proved to be. Ended up re-glueing a few tips and it pays off.
If anyone wants a pic of it to build your own just shoot me a PM and ill send you some pics. Took me about 30 minutes to build and was free since i had all the stuff laying around anyhow.

I've had the same experience with spinning arrows.I don't call my jig a spinning jig because I don't really spin the arrows on it.It's really more of a tip alignment jig.

Mine has a short piece of aluminum angle in front of the arrow's point.I establish a perfectly centered,reference dot on that piece of angle.

I then orient the blade vertically and sight down on top of the blade.That reference dot tells me which direction it is off and by exactly how much.I then move the point till it lines up with the dot.

After that,I turn the arrow 90 degrees so now the blade is sideways,sight down again and make sure the point lines up with the dot.The reference dot takes all the trial and error guess work out of the equation.

After building the tip alignment jig I also went back and checked the tips on some old arrows.Just about every on was off to some degree and more than I thought they would be.It's a good tool.

And from the looks of it you can use the oak base to press your points on.

Well... yours looks a bit more professional than my does.. haha looks nice! Does it work equally the same with field tips or do you pretty much just use it for broadheads? Looks very nice!

That's a fact Charlie.I probably shouldn't bugger up that nice piece of oak but it's just to convenient.I don't imagine I'll wear it out.

Cavscout,the beauty of it is,it doesn't have to be fancy to work just as well.The rollers for mine came with an arrow saw and I had the rest of the stuff on hand.I use it to check all points that I glue on to adapters but seldom seem to need to with screw in field points.I do like to use it to double check an arrow any time I shoot at game,to make sure the tip is still OK.

If you notice that notch on top of the aluminum angle,I use that when I want to find the balance of an arrow.The notch is slightly higher than the rollers so I slide the the arrow forward in the notch till the rear of the arrow lifts off the rear roller.I wish I had been smart enough to build this thing many years ago.Tradgang is where I got the inspiration to do it.
