This video shows how to fix a plywood boat. More accurately it shows how I started to fix some of the rot on my plywood catamaran. I cut out the rot and replaced it with new wood, watch the video to find out how!
I believe you are supposed to coat your plywood with resin before you do any joinery. It keeps the dry plywood from absorbing the resin used to join pieces. Which will weaken the Joint.
Dude! I wasn’t sure I’d ever see you start the project…thought something happened after the first and second video…missing in action for a while…super super stoked for you now though. Yeah bud. Hell yeah. Get after it! Don’t forget how some good music while you work totally changes the vibe and increases productivity by at least 317%.
I'm looking forward to seeing more work on your project. Am not an expert but have done some building with marine ply/epoxy. Using backing plates/doublers/internal framing where the repairs are joined seems like a wise thing to do. Also, I hope you consider a thicker glass lamination schedule compared to the original construction. If your budget allows, maybe some carbon fiber in the outer hull lamination to reduce weight.
I would have done the stringers first as that will be much easier, and more support .Also consider smaller screws, those were overkill, and as has been said prime the glue areas with straight epoxy just before you glue up. It will stop the timber sucking the glue epoxy in causing a dry joint
Cut your paper shape first and then draw it the boat side, it's easier than cutting out and then tracing the cut. Also use a spatular instead of a brush when applying the thickened epoxy as it will go on better, be snoother and fill any low areas.
Your stepped joint is a good idea, but not as strong as a scarf. If backed up with lots of grp both sides ok. Did you consider using backing plates, with a plain butt joint. Lightly glassed outside.
Tip, I get 3 or 4 goes out of a paintbrush. Wipe well, then clean with alcohol. Alcohol good for cleaning everything, fingers included. (Acetone is not good for you)
@@markthomasson5077 It’s interesting as a problem to solve I suppose, call it a learning experience at best……but for most it would be a money suck. There are many used boats better for the investment… All opinion of course
