[Public-List] Strengthening Soft Bulkheads.

[Wes Gardner via Public-List]

One thing I've learned over the years having built several hulls using the "tack and tape" or "stitch and glue" method is you MUST saturate the "end grain" of plywood with unthickened epoxy or you WILL have glue-starved areas. Even the surface should be well saturated so you end up with a high-quality lay-up that's not epoxy starved. Read up on some of the Gougeon's epoxy books, good stuff!

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?
