[Public-List] Strengthening Soft Bulkheads.

[Wes Gardner via Public-List]

Here's what I'd do, assuming there is no rot but maybe just softness-remove all the plam (plastic laminate) in the area, clean all the old glue off and get the area of the bulkhead where the chain played were ready to lay some cloth both sides. Before this, inject all the "end grain" of the plywood in and around where the bolts holes were using west system or sim. Fill the old bolt holes with thickened epoxy. Run a couple of layers of glass mat on both sides. Redrill the holes for 5/16 bolts. Either make backing plates or use big fender washers on the bolts.

You can do all this with the rig in place.

What do others think?

I suspect at minimum the laminate has detached from the plywood substrate.  There is relatively little apparent water damage in this area, but there is evidence of water intrusion.

If there is no wholesale rotten plywood, i.e., delaminating plies, missing pieces or punky holes but perhaps some soft or tender but intact plywood, would it be possible to consolidate the exposed plywood with some sort of penetrating epoxy product?  Git-rot (R) comes to mind.

In other words, if the damage is not extensive or covering a large area, can the bulkheads be repaired/strengthened without wholesale replacement?  Has anyone attempted to do this in lieu of replacing the bulkheads?
