    It's a milestone. Still lots of time until Spring. Are you planning to finish the transom on the trailer? It's going to be a tricky job.

    I'm sure the time will fly by. I do plan to finish the transom on the trailer. Unfortunately car repairs come first.

    Still need to add the skin back on the transom... in some places my transom is slightly further forward than others.. but when I put the skin back on I want it to be flush.. my plan to compensate for this.. I took a yellow plastic spreader, looked for the deepest recess and using a sharpie marked it on the transom. I then moved the spreader all the way around the transom looking for any spots that might be deeper.. found none... I extended my mark all the way across the face of the spreader.. then using some good scissors, I cut notches out of the blade of the spreader to the line I drew. Now I can use my notched spreader to apply the thickened epoxy to the transom thus setting the depth of the epoxy prior to putting the skin in place. I'll probably use some packing tape to hold the "skin" in place while the epoxy cures. I hope it works..

    in the meantime.. I've been meaning to add a bow eye to the boat.. I never liked how the winch cable rubbed on the bow and put a lot of downward pressure there when you are pulling the boat onto the trailer.. so throwing caution to the wind.. I marked and drilled two holes in the bow last night...I had planned for this some time ago when I installed a triangular gusset attaching the forward chain plate to the hull. In the forward edge I had inserted an oak backing plate for the bow eye. Unfortunately I never had a good plan for marking the spot for the holes in the bow... so when I drilled them, I missed the backing plate and went into the end grain of the marine grade plywood used for the rest of the gusset. I sent in Number4 Monkey with the oscillating tool and he removed the gusset/backing plate that I thought was so cool and now we are re-designing that to accomodate the two holes I drilled. I'll let you know how that progresses as well.

    That's all for now..

    My bow eye had bent bolts. I had that fixed and then reinstalled it with a ton of 5200 and a hardwood block. I used one of those blocks from a set that children play with (my Mom was a nursery school teacher.) Now I'd like to remove it because all together it must weigh 7 pounds but there's probably too much 5200.

    That transom project is going to take skills. After the skin is replace, there still might be some fairing to do. The transom will look really good painted though. I remember that you mentioned something about painting over the orange gel-coat around the hull. I've painted a few areas of my hull and found that gel is much much tougher and more durable than paint.

    I put the skin on yesterday, few words but here are a couple of photos.. so thousands..:)
    The notched spreader I made.. taking cues from laying tile... Then in pic 2 you can see the "legs" in the thickened epoxy to make up for any voids, or depth issues putting the skin back on.
    and in the third pic, you can see the skin is applied and held in place with some machine screws I had.. I hope they're going to back out ok. I plan to fill that seam all the way around with more thickened epoxy and will then sand it all down and paint it.

    That must have used a lot of epoxy.

    I think it was 8 pumps and a lot of silica. Probably 2 or more to fill in the seam. Then one corner seems a bit low so I may need to fair that a bit as well.

    Looking forward to seeing it all fared and painted.

    One thought. If you use the silica to make a faring compound, it will be as hard as nails to sand. The filler for faring in the red stuff (micro balloons.)

    More thoughts. It's my understanding that epoxy will adhere to gel coat. But you might consider sanding it down as much as possible in order to remove the oldest (oxidized) layer. It's an interesting project. Did you run a batten over the surface and get an idea of how much work has to be done?

    I spent about 20 minutes on it yesterday. I removed the screws and sanded off most of the excess epoxy that I managed to get all over the place..I still have some cleanup to do with that. The top corners seem to be slightly recessed so I may need to do some buildup there. The rest of it seems pretty flush and I think will blend nicely with just filling in the seams (but no I didn't run a batten on it). I think there is some filling in to do around the cockpit drains, and I might have some alignment issues there which will require some cleanup prior to installing the brass drains. I had thought about using fairing compound instead of silica, was leaning towards the silica as I have plenty on hand, but with respect to your opinion/suggestion. I just ordered some fairing compound.

    The silica is good for the biggest depressions but it's very hard to do the final coat and fare with it. It sands like iron.
