Ace 203 spine tester ??

[slowbowjoe]

Leaning toward the 203 spine tester (this will be used only for wood shafts). I see that the weighing system is different on these; the weight is at one end, rather than the middle of the shaft... and the pin the shafts bends on does not appear to be centered either.

Any feedback on the 203, for ease of use and consistency ?

Folks have figured out the geometry to give same results as a weight applied to the center of a shaft supported between 26" pins.

Have to zero the marker every time you change shaft diameters  using the large off set knob on the lower left that holds the shaft.  I found the set or zero mark on mine to be a bit off.  I tested several aluminum arrows of different sizes and had to move the set mark a bit to get known spine values.  Accurate and repeatable as long as you set the zero when changing shaft diameters.

I've got the 'Ace Spine Master' (listed in Kustom King for $118) and hangs on the wall with the weight being applied to the end.  This unit is very accurate and easy to use and I like that it doesn't take up bench space.  I'm not a mass quantity arrow maker, but for wood arrows, I want them to accurate and when I make my own, I find the consistent spine and align nocks accordingly. I've tested this against aluminum arrow deflection and it's accurate, so for a simple piece of equipment at half the cost of the bench models I'm pleased.

I ditto ray on this one. Bought mine directly from ACE

Thanks for the feedback guys, sounds like it'll do what I want it to do.
I'm used to zeroingout for each shaft on my old model 101; the 203 seems to have a better design.

Got this a few weeks back and it should have been one of the first things I bought when I switched to woodies.Well live & learn lol.
  I ordered mine directly from ACE,lot's cheaper and quick service. If you are serious about shooting wooden shafts consistently in to the sweet spot you need this tool.
