Got the Plank Strip cutter up and running today. Ended up with a Dremel timber cutting blade fitted to a Dremel Ez Lock quick release mandrel.
Mounted it in a drill press rather than the Dremel and then just a matter of setting the plank thickness as the gap between the blade & drill plate and using a pine block to keep the timber pressed against the blade while cutting.
4mm x 4mm strips are required to mount the deck as there is not much clearance between the hull & the safety rail posts. As long as its well epoxied & sealed all should work out OK.
Starboard strip has been fitted & epoxied, now for the Port side & the stern
