Brycey boy I suggest you look at the cheapest version that Ace sells. Clint gave me one and I love it. Its super simple and only works for wood or boo. It mounts to the wall.
Only when the last tree has died and the last river has been poisoned and the last fish has been caught will we realize we cannot eat money.

Make one yourself Bryce.I made this one years ago from a book called Bow Making Accessories.Very quick accurate tester.A dial indicator costing 20.00 was used with spare pieces of wood laying around.Nice on and off switch with a nice zero out option.26" width between the posts[not sure if that's ISO] with a 2# weight to hang onto shaft.

I use a micrometer attached with a clamp, and made my weight with lead ingots, and found the charts on line.  Set it up to be not collapsible but it can easily converted to breakdown mode.  I think I am going to make an arm the will support fletched arrows, too!  I can send you a base and upright (walnut)' you  just have to make and set the yardarm, and mount the pegs.

Thanks Chris I’ll look into it.
The one I have now is one that I made. It’s accurate as all hell but I hate having to check my deflection sheet the cross reference the actual spine of the shaft.

My dial indicator reads out MM to the poundage of the spine shown on a converstion chart taped onto the spiner for very quick reference.Easy peaszy and very fast.
