I built an arrow crester for about $15.

1 Black and Decker re-chargeable screwdriver

1 scrap 1"x 6"

4 finish nails crossed to form 2 "V's"

1 piece of 1/4" shrink tube as a nock receiver  

Works great!
 
 

Great idea! That arrow looks awesome.

That's creative.  Good one!

Awesome! Thanks for sharing.

What's holding the screwdriver?

Thanks guys!

The screwdriver comes with a charger that you can screw to a wall. I screwed it to the board. That way you can run it while plugged in.

Beats the heck out of using a Hamster spinning a wheel in a cage and stopping whenever he feels up to it!    

Very nice!!!

I like it! I bet it would even do double duty, and you could spin test for good broadhead alignment. Well done!

Where did you/what kind of screw driver is that?? I like the idea.

It's a Black & Decker re-chargeable. Mine is older but, I just looked at their web site and they still have a similar model.
