Mike's 77 22-2 Rebuild

I think the latter is probably best so you can "set" the shape - definitely wet on wet. Maybe Chris (dirtwheelsfl) is around and can offer his insight.

[Tampa Bay Mike]

Yeah, the more I consider it I think the convenience of laying it all up at once will outweigh the small extra cost of the MDF for the form.

The cutting and glassing is the easier part, keeping everything nice and fair is the tricky part.

The shape really wont be locked in until the vertical coaming is glassed on. Id also say use some type of solid core, the honeycomb will be a pain with all the open cells to deal with.

Another way is to glass in some knees every few feet, cut a bit of crown in them relative side-to-side of the boat (2-3" crown is good for a boat this size) and use that as a sort of permanent jig (you will want a few knees under there anyway). Then take a fairing batten and draw a nice shape fore-aft on those knees and cut them vertically on your marks. Then put your coaming on first, and proceed with the top.

If youre using a "floppier" core you will need more beams in your jig to keep it nice and fair. Youve obviously gotta get rid of the jig to put the coaming on if you go the temporary jig route, so make sure its well supported somehow to keep shape.

Did one on a 25 Bert recently.

Any questions just ask!

[Tampa Bay Mike]

Awesome, thanks for all the info. I never would have thought about doing the coaming first but it makes sense to help keep the shape. I will check out that link for sure.

[Tampa Bay Mike]

I went through a bunch of those pictures and you do awesome work. Thanks again for sharing that.

What did you use for the core on those?

[Tampa Bay Mike]

Got the leaning post 95% done last night as well. Just need to screw the rod holders down and add a catch for the slam latch.

I've been doing some more research on the cap and I'm about to get started on it. I decided to go with foam over the honeycomb and I picked up four sheets yesterday to get me started. I also made some cardboard templates of the support cleats that I transferred to some scrap coosa.

Before I start cutting and gluing, should I core the hullsides or do anything else to stiffen them up a little more? I added one new layer of 1708 months ago when I did the bottom and they got almost another full layer overlapped last week when I did the second layer on the floor. They don't necessarily feel flimsy but I can flex them by hand in the middle if I try. I have no idea how much stiffness the cap will add but I also don't want to have an issue if I bump a dock, etc.

With as high as you raised the deck, itll be plenty stiff without coring the hullsides...

Good to hear, thanks.

Getting started on the cap. Got the cleats taped in along with the front and rear bulkheads. Plan to get the coaming strip done next and then the top, but first another supply run. I've about killed a roll of 1708 and am running low on resin.

What material and size for the bulkheads? How far apart is the rear bulkhead from the transom? The boat looks great! I hope I’ll be able to make mine look half as good. Keep it up.

Thanks, Joe! I used a 5/8" 4lb foam from FGCI. On paper it's comparable to Divinycell h60 but about a quarter of the price. It's 16-18" from the transom, don't remember exactly offhand. Enough to make three small compartments and leave access to the thru hulls and engine bolts.

Man. That thing is looking amazing. You are moving right along.

Thanks! It's still a while away but I am starting to see the finish line on the horizon. Trying to stay on it.

Great progress
