Renewing Trailer Bunks
The bunks off the old trailer were in terrible shape. The aft ones were cracked along their bottom flanges, and were getting crushed by the boat. I looked at making altogether new ones, but decided to refurbish them instead.
Once I peeled off the rotting carpet, and sanded off all the old contact cement, I ground away at the failed areas with the Kutzall ball and the pneumatic 90. Upon closer inspection, I decided the solution would be to build carbon "L" channels to beef them up. Rather than directly glassing the bunks themselves, I decided to fabricate these parts on the workbench. I made a quick and dirty mold, which was a skewed "U" shape, as the angles involved were not a true 90. After bagging, I split the U and glued everything up. From there it was just a little bit of fairing, some primer, and a nice Awlgrip topcoat.
