As you can see it's a 2x4 to clamp the oak too, and a guide rail for the circular saw.
The 2x4 was not square (who would have thought it?) so I had to set the saw at a slight angle to make a square cut. For once easier done than said.
I need to tidy up the saw burn, but otherwise, happy days.
As always the question, Epoxy or Balcotan Marine PU ? It's a nice smooth flat surface, that I can clamp good and tight and it will be above the water line. I'm leaning towards Balcotan PU. The test peice that I glued together with balcotan and left out in the weather, left in the shed, and generally abused is still holding strong.
Gluing it straight is just means I need something to clamp it too.
