Cut the transom again. I'm getting better at ripping stringers as well.
I used about 20 screws this time, and a few clamps around the edges. Tightened (inside screws first) until contact was made then another half turn. Squeeze out all around, but not a lot.
I'll have a look in the morning but it looks much much better. Used about 500ml (over a pound) of epoxy plus fillers and wetout coat.
Thickened to a bit past mayo, just enough to hold shape when spread with a notched spreader.
Used some excess to start plugging the outboard transom holes.

Re: Stringers AARGGHHH!
I'd say you are in great shape. I figured 12 oz was sort of short even...but didn't want you to overmix.OneWayTraffic wrote: ↑Fri Jan 31, 2020 5:53 am Cut the transom again. I'm getting better at ripping stringers as well.

Re: Stringers AARGGHHH!
I have predrilled some hole so could always fill with excess.
Have posted a photo so people reading this can see what worked for me. Hand turned screws in pilot holes the way to go I reckon. Easy to adjust pressure. Clamps for places around the edges where small gaps show.

Re: Stringers AARGGHHH!
You can't fill big holes or the epoxy will exotherm. fyi

You can save the plugs from the cut holes and use them to plug the holes.

Re: Stringers AARGGHHH!
I have a 3 inch hole in the bottom of my dory filled with epoxy and glass threads for a shoot through hull transducer which didn't "exotherm" beyond working. It probably got hot while curing but not a problem.

Re: Stringers AARGGHHH!
How thick is your glass/epoxy there and does it seem to effect the transducer's abilities?
I would like to do a small FF that way too.

Re: Stringers AARGGHHH!
All depends on thickness. 3/4"thick will exo and crack about half time on say a 2" wide hole, so if you are thicker, like 1 3/4; that shit will be smoking if you try to fill it. Mine was just a warning to the OP to avoid trouble. Epoxy can catch fire in a big ball; never saw it, but I have had a couple cups melt..
For a ducer fairing, there is no need to fill the whole hole.

Re: Stringers AARGGHHH!
So fill it in a couple of smaller batches over the course of a couple days. It’s still going to form a chemical link and greatly reduce the risk. Not a hard problem to solve.

You can even just wait an hour and a half or until the last one starts to cool off.
I just know he had trouble, so trying to watch out for the guy!
