Can I run bolts from the back of transom through transom to the forward part of transom with backing plates on both front and back of transom above the cockpit floor. Sent from BlueMail On Aug 7, 2018, 8:06 PM, at 8:06 PM, Bob Eeg <montgomeryboats@hotmail.com> wrote:
Doug First you have to understand Jerry M’s excellent answer about the tubes.
The Transom has a vertical dimension. About an inch and a quarter FORWARD is the Back of the DECK. Also an almost vertical dimension. This is a Gap. Very tight area to work in. Bob

Bob... not sure what you mean by 'air gap'. Please elaborate.

Wow! That sounds complex and hard to do. My company is called Jury Rig Construction! Get it? So, how about running bolts all the way through the transom with two backing plates, one on the very outside and one on the cockpit side of transom. Both are external and visible with bolts and nuts. Also would use 5200 to attach stainless backing plates on both sides. See a problem with this idea?

There is a technique for putting the interior backing plate in place without cutting large access ports.
I used 3/4 inch marine ply cut to the approximate shape based on the desired location on the outside of the transom. Drill the bolt holes aligned with the transom ladder, backing plate (while outside the hull) and the transom. Then enlarge the holes in the backing plate slightly to accommodate T nuts ( blind nuts) of the appropriate size. Install the T nuts on the backing plate.
Find two 8 ft lengths of reasonably stiff wire. I used house wiring, not striped. Run the wire from the outside of the hull through two of the opposite corner holes. You might hook a washer on the outside end so you don't pull the wire all the way into the inside. Go inside the cabin an capture the wire, then pull them through the corresponding holes in the backing plate with the T nuts on the bow side of the backing plate. Firmly attach a washer and a retrieval string to each wire. A diagram would show the sequence - string, washer, wire, T nut, backing plate, transom, washer. You can then trial fit the backing plate by pulling the backing plate to the interior of the transom using the wire. Check alignment of the holes by putting bolts through the transom into the T nuts on the two holes without the wire. If the holes don't align or the backing plate does not appear flush from what you can see through the holes, extract the backing plate using the string, (without tension on the wire the backing plate will fall down allowing the string sufficient friction to pull the plate back). Trim the backing plate for a better fit. Excess fiberglass near the top of the transom can cause a poor fit so do not try to get the backing plate all the way to the top of the inside transom.
If all fits well, lather the backing plate from the center to just past the T nuts with a thick sealant ( I used 3M 5200). Pull the backing plate into place using the wire and install two of the bolts for a snug fit, remove one wire using the string, install the bolt for a snug fit, remove the second wire using the string and install the 4 th bolt.
Tighten all up and let dry.
Thanks

I was thinking of running some bolts through the transom to the'interior'/ cockpit side of transom for more support. That way the is backing on the back side of transom as well as other side of transom, both with backing plates. The players could be made to look nice with team. What do you think of double backing plates built like you said.
