Week 12 - 84 days

On Thursday work progressed on our used trawler blister project; it was time for step 3, sanding the bottom.

A protective tent of sorts was again built around the boat to protect other boats and people from the flying resin dust that would be generated.

A 6 inch sanding disk of 36 grit was used to sand the entire bottom to a smooth finish, and yes, it is very smooth.


The next step will be to fill the bottom. In this step, epoxy resin will be mixed with cabosil to a peanut butter consistency and them trowelled onto the hull. This will begin next Tuesday.

You see a photo of me hosing the hull with water; here is why.

When Tom completed his sanding, he found trace elements of moisture just beneath the surface; the sanding released it from the resin.

Although its normal for this to occur, washing daily removes the remaining contaminants allowing the hull to completely dry by next Tuesday.
