Garage Works - 2/5/2026

I ended up taking another rest day (waves weren't supposed to be that good).

But in the interest of getting prepared for the next few days, I knocked out a project I've been wanting to get on for quite some time.  The AFS UHM 75cm Skinny mast had flat (pan head) bolt holes.  I use countersunk bolts - so that was a problem.

If you use countersunk bolts in a flat hole, all the pressure the bolts transfer to the mast are done so in point loads 

I dug through several spots in the garage until I found this - a countersinking drill bit.

Here's how the countersunk bolts sit on an unmodified bolt hole - proud by a long shot.

And here are the bolts in a hole that has been countersunk.

Nice and recessed.

The load is now spread out over a much larger area.

Just in time to setup a prone foiling session...
