Bow Cap
All
Attached are some pics. I only had to do the bow cap but I'm sure the process would work for end caps.
DCP003 is what I had left of the original bow cap. I cleaned it up and coated it with melted Gulf Wax but I'm sure that any type of mold release will do.
DCP004 shows the mold. After the wax coat I laid 6-8 layers of glass and resin over the wax. I did this like you would do paper mache. I cut the glass into small pieces and worked in small batches. I only mixed 1-2 oz of resin at a time and worked with a small acid brush (soldering flux brush .29 at Home Depot). This allowed me to hold the contours without getting wrinkles in the mold.
DCP007 shows the mold and the two halves that I made with the mold. I waxed the inside of the mold and built the halves using the same "paper mache" method. To speed the curing process, I mixed the resin very rich with hardener and used a heat gun in-between layers. You'll notice that one of the pieces has some white on it. That is because I tried using a micro balloon thickener in the resin to bulk it up but I was not happy with the results.
DCP0011 Then I fitted both halves together checking them on the boat as I went along to insure a good fit. Once the fit was good I glassed the two halves together
DCP0016 & 19, Once the halves were assembled I added some body filler to the inside of the arch on the top and bottom. After shaping that extra filler the new cap fits very snug to the bow and head stay tab.
The fit is so close that 3M 4200 or similar will hold it in place.
Finish with filler where needed, a few coats of paint and viola...
All in all it was a pretty easy project and about the only choice I had. It seems to have worked out pretty well. I will not get it mounted until the spring but I'm very happy with it
I hope that helps.
If anyone would like more details, just let me know.
