(I shoot a 45# Kmag that I overdraw to about 29")
Well I got another batch of 36" 23/64 Poplars spined at 56-60, and took a few outside to bare shaft em.
They all snapped on impact.
The first arrow was nock left, so I sawed the next 2 down about 3", the next 2 were only a little nock left, but still blew up on impact (halfway up the shaft).
Am I doing something weird, or is poplar just a really weak wood?
Any tips (including advice on touch wood) would be much appreciated. Thanks.
I have broken a lot of ash shafts that way. Ash ain't known for being easy to break.
I don't bareshaft wood anymore.
I don't think your shafts are too weak, they might even be a touch stiff, at least the way I shoot. I would fletch them up and shoot them, and see if you like them.
A lot of folks go for shafts much stiffer than I do, but I know what works for me. I shoot K-Mags a lot. Cool bows! :)

The main thing with bare shafting is to step back 15yrds - at least. From what you wrote I suppose, you were to close to your target and no wonder, all shafts snapped.
Allow plenty of space besides your target and never ever bare shaft a broadhead ...
I agree with Killdeer, Fletch them and see how they fly... cut 1/4" re taper and shoot again till you get great flight... I only use bareshaft planning to help fine tune... just like O.L. Adcock does on his website.
If those shafts are in fact 36" long and you are not cutting them they spine 26-30# take off 2" and they are still only 36-40# Your Kmag is about 51# at 29". Spine is calculated at 28" not the full length of the shaft. Even cut to 29" they will be a tad too weak, as the Kmag is cut to center.

Good info.
