Lake Oswego has been having a heat wave; we had a high of 82°F yesterday, 80°F today and an expected 85°F tomorrow. For most of the boat build the temperature in the boat shop has been in the 50’s. At those temperatures I use a fast hardener designed to cure between 40°F and 60°F. As the temperature started to climb I switched to a slow hardener designed to cure at 60°F and above. Yesterday I used all of my extra slow hardener designed to cure above 70°F. I have very little need for the extra slow hardener since I don’t do much boat building during the summer so I had just enough to primed the inside of the hull. I was able to finish fiber-glassing the inside of the hull by saturating the fiberglass cloth using the slow hardener.
So far on the build I have used about 3 gallons of epoxy and hardener; I expect to use at most 1 more gallon. I have gone through 22 yards of 6oz, 50 inch wide fiberglass cloth and I should use a another yard to a yard and a half. For peel ply I have gone through 16 yard and I might go through 1 more but I have 4 spare yards just in case. I purchased different epoxy fillers per the designers recommendation and I will have enough left over for two more boats. It is better to have a little left over than to run out and waste time and money getting a little more to finish the job; actually the time cost from running out exceeds any savings by buying just what is needed.
The thwarts, bridge deck and anchor deck don’t have any anti-skid coating so I am thinking of using Dynel fabric which has a texture similar to coarse cotton duck. By not filling the weave all the way I will be left with a very abrasive resistant non-skid surface.
