Dave,
Skip over the idea of using "foundation" grade ply if you plan on any coatings. It's been treated to a higher level and will not like the CPES and resin. |

Pete, what our your feelings on foundation grade ply, the stuff does well below grade on a house. Price wise it seems like a good compromise over marine grade for panels, not sure what it is treated with and what the treatment does to fasteners over time or how it interacts with cpes

Thanks ~ Thought I was having trouble with my search.
I will look to make it work with the ply and butt blocking. |

Michael, I did a search and couldn't find the thread where the member did his coaming pads. He's the one who discovered that butt blocking was used by the factory with 8' lengths of ply. He ended up doing the same but did go through the scarf idea like you did. I'd stick with the ply rather than a solid due to the plys cross grain veneer layers. I feel it will be more stable. |

Thanks Pete,
I'll go search for coaming pad backing. Are the easy to find big box store long boards a no no? Butt block like this one at glen-l Scarf joints look cool but might be over kill unless I can find a trim guy who needs auto work. |

Exterier ply is fine. The CPES treatment will really soak in so the stapling won't hurt the treatment. There's a thread on coaming pad backing which is longer that 8'. The factory simply used a butt block at the joint. It gets covered up and not noticed with the foam padding.

When it comes to WOOD ~ I'm lost my wrenches don't fit and it doesn't weld very well. HELP !
I'm searching for a suitable wood for interior trim panel backing ~ (Simple?) Skimming the BOATBUILDING WITH PLYWOOD, by Glen L. Witt CHAPTER 5 - LUMBER didn't do much for cleaning things up. Searching the site has not hit a home run yet either ~ probably just me. I'm worried about rot / splitting / weight / flex / swell - expansion / compatible with trim staples. I have CPES and plan to coat 100% 2x before covering (I realize staples will cause holes in the epoxy coat). I've looked at generic 1/4 plywood but some of my narrow trim pieces are longer then 8' and I can't weld 1/4" plywood. Thanks, Michael |
