Hung a couple axes this weekend, both on 32" link handles I got from ACE.
First was my 6lb embossed Flint edge head. Turned out ok, but I wish I could go back and re do it. 32" total length, the eye was so deep on this head that even seated all the way down on the shoulder i only cut about 1/2" off the top at the most.

The next was my old 8lb maul that I used for years. Before this, I had it on a 36" bent link handle that I put on probably at least 10 years ago - and it lasted for probably 25+ cords of wood. The old handle wasn't great and had crazy run out (this was before I knew what run out was and how to select a good handle - but even back then I liked splitting with a bent handle). but it took a decade and tons of wood for the handle to crack at the runout and that is with an 8lb maul head - so I'm not convinced that runout is terrible on a 3lb axe handle.
anyways, the maul hang went way better and I'm much happier with the hang, really nice and tight with awesome wedge depth. Both handles got thinned and octagonalized with my 4 in hand rasp dude - except the grip which I leave round(oval), but thinned a little and left rough (as recommended by Bernie Weisgerberin the Axe to Grind video). The maul handle ended up about 30" total which I've decided is the optimal length for me.
