Ah, he winged it.

We have a shipsaw with a giant bevel gauge (custom) with extra long bevel arm. The cut man stands at the cut and calls out the bevel gauge numbers written on the timber while the table man stands on the table while adjusting the bevel to the correct number on the gauge slowly. Slow steady constant pressure on the bevel arm gives you a clean accurate running bevel. Changing it suddenly a few degrees every few feet gives a series of angles instead, which requires much more clean up. Still, not a bad solution if you can't find a helper and must cut running bevels on your own.

Im exploring the idea of pretreating with an anti fungal agent such as ethylene glycol. Has anyone here tried this?
Cuprinol is what you are looking for. I have found it to work well. I think there is a clear now. It used to give the wood a green hue. It penetrates well and I have soaked the end grain for a few hours in a partially full coffee can.

Pure EG is expensive and difficult to find. I have used it to kill existing rot spores followed by Smith's CPES successfully. YMMV.

And forget about the glycol. It will only screw up the bond of the epoxy to wood. Just coat the wood correctly and keep it painted. It will last a very long time.
Yes, either paint it or use Cetol instead of epoxy. Cetol is oil based and has preservative in it.

Roy, that is a brilliant idea using a fire hose to clamp a built up spar! Thanks for that.
