Glad to hear you're making progress and even happier to read that Paul calculated the loads before going with pop rivets. I share Neil's thoughts and well wishes for success. I'm counting on you to let us know how it works out.

Best wishes on everything, I honestly hope them rivets don't bite you in the butt later down the river, hate seeing such enthusiasm go sour and cause grief later, just a novice opinion

Yeah. We know they’re not the best option. These are blind, self-sealing AND we added a dab of marine silicone.

The engineer did put some thought into this structurally. I’m good with his call on it. Loads have been calculated.

Yeah, pop rivets aren't the best choice since they won't be water tight, but you might get away with it if they're all sealed up behind the outer transom wood.

Update from us.

While I sit at my desk STUFF is going on out there. I have been told (several times) that there was not a straight area on the transom. It has been... Worked on... And symmetry is a bit up for grabs too. As many of you have said: these are all handmade individuals with their quirks.

So where are we? New T's have been installed, and the transom wood is being cut.

The wood will have a high swoopty doopty section to accommodate the longer foot on contemporary outboards so that the prop is in the right place. Used Art Doc's as a visual guide. Used some old drywall offcuts (we're building a bathroom also) for the template - worked really well. Much better than cardboard.

As for the type of wood. We're sailors, so it's a piece of marine ply - I forget the type of wood exactly - possibly a Sapele ply. It will be stained and epoxied.

As you all know, it's a slow process. But, we're getting there!

Try filing a flat spot on the dome of the head, then center punch dead center, using the next size drill down from the rivet size you are replacing with, drill through as squarely possible, lol, I posted this after I seen Ray's reply, your in good hands

Many thanks - that is very helpful and gets to the heart of the difficulties we were having.

You need a tool to keep the drill centered and perpendicular to the surface the rivet is holding.
The best tool is this store bought one, really works great.

www.aircraftspruce.com/catalog/topages/rivetremoval.php

Here are two examples of homemade ones, the one made from a bolt works good but it's short so you have to be careful to keep it square, the other one is better because it's longer and easier to hold.
Both can get chips built up and usually have to be removed before you drill all the way through, that is the one area the store bought one is better.
The recess needs to fit closely to the head of the rivet.



Ina pinch the next easiest way is to knock the head off the rivet with a sharp wood chisel, the way the cutting edge of a wood chisel is made you can put the beveled side flat with the sheeting and knock the head off without getting into the sheeting(with practice anyway), then you can drill out the rivet through the revealed shank of the rivet.
Don't try to drill from the formed head side (the side that was mashed in the riveting originally) because that side often moves during the bucking process and will usually not be centered on the shank of he rivet.

The ones in the transom braces can be especially tricky, the heads are often sort of recessed in the sheeting from years of the transom distorting in use, a centering drill and a good eye can be the only good way to center on the rivet head. This photo is a little deceiving in scale, the body of this drill is 3/16" the tip is 0.080".
