Pathetically I cannot remember how to post the other way. More research

If you want to post a pic when you talk about your boat, which you should, follow the instructions here http://classicaquasport.com/smf/index.php?topic=12725.0  - don't attach them - you are limited by file size and guessing what size to make the file will usually reduce the pic too much. Uploading them into your "member gallery" is better for viewing and the system takes whatever size you upload and resizes it to the best size.
Spend a few minutes to absorb the instructions. It's really easy. Remember if using a phone to take pics, to hold the phone horizontal with the lens to the left.

I think you are looking for "webbing solution" for the splatter effect.

Posting pics is a little different now.  Tried the mold idea I had for a transom cap and it worked and it didn't work.

I ended up not us8ng the cap because the quality was poor, i.e. I really don't know what I am doing. Good idea though. Used the packing tape release method

Look at you making a cap.  :thumright: That looks great. The way to install it is to use thickened resin but don't crush it into place.

If it was only one layer, that was the problem. I think you didn't make it out of CSM, correct? You can use the tape method but use CSM: 3/4oz at first to get the shape and then another layer of 3/4 and work your way up to 1.5oz and a couple layers of that.  Try to do multiple layers "wet on wet" - in other words don't mix the resin so hot. Get 3 layers of 3/4oz on the whole transom top and let it kick. Obviously you have to pre-cut the CSM and have it all ready before mixing the resin. If you have someone to help, use them.

You're experiencing the "1708 doesn't like corners" problem. Use CSM, you don't need 1708 for this.

I didn't try to wrap the 1708 in that last pic, but it was about the same when I did. So far I have a layer of 1708 9n back, on top and on front. Then a layer of mat that I did get to wrap pretty good at your direction. Then another front top and back treatment of 1708. I think it will work as is but I'm going to do another layer csm like you suggested. The front lamination on the transom is easy 1/4 thick at this point and everything is solid. Pretty excited about the whole thing.

Was fitting the drains in for the stringers. Cut 2 inch pvc in half lengthwise and was going to smear thickened resin  down each side to attach to floor . Is that the norm? I assume the goal is water tight stringers.  I am leaving an inch or so out either side of the pvc to allow for glassing. I did not put them 12 inches out from transom like the drain. Hope that's not a mistake.  Thanks as always for everyone's input.

Yes on the water tight stringers - but hopefully theres never water in the hull where those would be needed. I did the same thing, left about an inch of pvc sticking out the side to make a good seal. During the build before the deck was on I did manage to get water in the boat that needed to drain, there was always a little that didn't drain because of that 1 inch. Ended up trimming as close as I could to the stringer without messing up the seal.

So far I have asked about almost everything and everyone has been very responsive. Thanks. My instincts are usually close to what all of you recommend, which is encouraging, but sometimes complete mind blank and always a little off.  this bunch is quite the security blanket.  Here is where you saved my rear:
    × would have screwed the stringers up badly
    × and the drain too
    × csm between the Coosa transom boards
    × many many more

Thanks

Stringer lamination port side. Had about a foot plus of overlap of old stringer under new which I smeared thickened resin on. Should be solid as all get out. On the inside had about 6 inches of overlap but they were separated by about 3/4 inch so a piece of Coosa smeared both sides  went in there. Then laminated stringer to floor with 6 in strip of 1708 on both sides.

On another note to would be rebuilders, if you can rig some roll up like the pics for your 1708 and csm do it.  I  always forget a piece and have to race in there to cut .  Can't imagine not having those rolls like they are.
