Made it from pieces of scrap would that would of just been firewood. I took a really simple approach to it. Essential I eliminated the whole need and gauge for a simple broken piece of tape measure and I measure off the weight itself. The weight was made of scrap metal.
I tested some carbon arrows on it and my tester was only off by 1/200th of an inch so its very very close. The 400 arrow on my scale read 405.

Lookin' good. Possible to show us how you're doing the measurement?
-
Yeah I'll get a picture later. I haven't comlletlwy finished that part yet.
-
that ought to work. good way to make a quick easy way to read the deflection measurement

You mentioned using carbon arrows to check this tester you made. Keep in mind that carbon shafts are tested on supports 28" apart using a 1.94lb weight.
Wood shafts are tested on supports 26" apart using a 2lb weight.
Testing a carbon shaft on a wood setup could give you some wonky readings.
Don't ask me why there are two different testing standards.

Him I didn't realize that maybe that is why mine was 1/200th over.
Really since I plan to make my own shafts I'm moteninerested in the number I get on my scale so I can shoot consistent arrows.

If you use the tester as a point of reference then it will work great.
