Precutting Bevel on Chesapeake Triple Sheer Clamp

[Yummyipa]

I’m planning out my Chesapeake Triple build from plans. Since it doesn’t have a rolling bevel, I’m considering cutting the bevel on the table saw before I attach the sheer clamp to the hull panel. The two potential issues I see are 1) the deck radius is relative to the ground, not the hull. In checking the plans, it appears that the angle of the hull changes slightly from bow to stern but not a lot (2-3 degrees; see image where I’ve overlaid the foremost cross section with the aftmost). This seems very manageable, I would just cut the angle a little steep and plane down a small bit to get the correct angle throughout
2) I would need to be spot on when epoxying the sheer clamp to the hull panel instead of attaching proud and planing down to fit. I’m not sure how much harder this would be as I’ve never down a 21 ft glue up before.

As I’m writing this I’m thinking it’s probably not worth the trouble just to avoid some planing, but I’d take some opinions anyway!

i would plane it.

while it may not have a particularly dramatic rolling bevel, the bevel does change and that’s all a ‘rolling bevel’ means….that it changes between some of the stations and you will be gradually adjusting (rolling) the bevel smoothly between stations to acheive the right bevel at the station locations.

i think you pretty much sorted it out when you talked abour your plusses and minuses above of doing it. if you have a sharp block plane, its not a big job…and definitely good practice….getting good with the block plane is a really important skill for boatbuilding and other parts of the build yet to come.
