This forum should have a section for dumb mistakes and suggestions on how to fix them. I could certainly contribute a few anecdotes. For example: I am building a Chesapeake 16 from plans. All went well until I glued on the sheer clamps. Rather than use the suggested back to back method, I elected to use the edges of my long work table and to glue each panel separately. Long story short, I glued one sheer on the wrong side and ended up with two left side panels. ( I was never good on spatial orientation tests)
Realizing my error (after the epoxy dried) I thought about having to buy more ply, cut and scarf a new panel and try to match it to the other panel. I also (briefly) considered making two boats. Then I had an inspiration. I have a portable thickness planer. I figured I could run the panel, sheer clamp up, through the planer and plane off the clamp. If it worked, I could salvage the panel. If it didn't work, I could still use the panel as a template for a replacement panel. Well, it worked great. I created a lot of cypress shavings for the garden, and after about 20 careful passes through the planer, the sheer was gone and ply was virtually untouched. The last 2 passes were done very carefully. I'm going to paint the hull, and I don't think anything from this fix will be visable. So, should anyone else screw up and glue a sheer in the wrong place, find someone with a sharp thickness planer. It will save your day
I've now made a new sheer, and glued it on the correct side. I quadruple checked. Signed, dummy aka Randy in Florida
