Tried a different rasp angle on a tough quarter crack and it actually worked

Had a horse with a deep quarter crack that just would not hold a patch. After the third try, I switched from my usual 45 degree rasp angle to a much shallower one, maybe 15 degrees, and worked it super slow. The idea was to take off less material but make the surface rougher for the acrylic to grab. Left it for a full 24 hours before putting any pressure on it, which felt like forever. The patch held solid for over a month, which is way better than the week I was getting before. Anyone else messed with rasp angles for better adhesion on problem cracks?

A full 24 hours of waiting would drive me crazy, I'm way too impatient for that. The shallow angle makes sense though, you're basically just scuffing it up like sanding wood before glue. I've never thought to go that flat with the rasp, always just did what I was taught. A whole month from a week is a massive win, makes the wait worth it.

Right? The waiting is the absolute worst part of any project. How do you even fight the urge to just slap it together and hope for the best? I have to literally put the glue in another room or I'll mess it up. That shallow rasp trick was a total game changer for me, it feels wrong until you see how much better the glue grabs. Honestly, most of what I was taught were just shortcuts that never really held up. Getting that extra time out of your work makes all the fiddling around totally worth it.
