Look what followed me home. I think it's going to need some redesigning. I can’t wait to see what you do with this one!

Oops that was the last post, the transom stuff is in the beginning of the thread.
As you will see I'm not a fan of sandwiching new aluminum over old corroded transoms. It is a perfect spot for more corrosion to continue.

I’m having to remove a few ribs to get the rib ands and hull back to shape. After removing the first rib I found a lot dirt, grime and corrosion between the hull and the ribs. It’s cleaning up pretty well, but there is some shallow pitting around the rivets where the rib and hull are sandwiched together.

Any suggestions on reassembly? I plan use 5200 between the rib and the hull. Is there another product better suited for this purpose such as Coat-it or gluvit?

 

[BOYS & TOYS]

Epoxy products should be used after riveting and metal work. Seams are the best applications for them. 3m 5200 for everything else

 

[SHSU]

JB Weld to cover the pits and 5200 to seal the rivet.

Alright, how do I get this thing out?

Not in one piece

Not in one piece

Yep..
Transom replacement requires new drain tubes

I hacked at it with a saw for a while and got it out. Is there a preferred method for cutting sheet aluminum. Angle grinder? Circular saw with metal blade?

 

[SHSU]

A metal sheer machine would be the easiest, but I have done both angle grinder and metal saw. Both work.

I cut aluminum with all kinds of woodworking tools. Jig saw, circular saw,bandsaw and even oscillating saws when no other saw will work.
WD 40 makes a good lube for cutting aluminum. It keeps the cutting teeth from loading up.
