I didn't want to throw out something that was still usable or use it so mangled so I did what we do.? I drew and printed 2 combs in a few minutes to try to fix it in two steps.? I might try another round with tighter tolerances but I can live with this.? I did not take pictures along the way but this should explain... ? tap the first comb down into the fins before the damage.? using a wood block (or you could print something) so you don't do more damage, drive the comb all the out the damaged end.? repeat with the second comb. ? ? ? Happy to share stl's if anyone cares.? This is the heatsink ? I bought the 150mm variation that will eventually go on a K9HZ 20w PA. ? Doug AC9RZ |
