I’m a visual thinker. Could you attach an image showing what you mean?

I just posted a picture. The difficulty is the 1.85 degree angle that I need for the transom

It would be helpful if you share the .skp file with us but my guess wiothout seeing it is to model the three boards as solid components or groups and then model a cylinder as a “drill” and objects for the other cuts. Then use the Solid Tools to make the cuts.

I am not familiar with the solid tools
Seems I need to learn them
thanks

Ok, that helps a lot. Which direction does the 1.85 degree slope need to go? Vertically (so the top of the whole assembly is narrower than the bottom)? Or horizontally? And if horizontally, is the front meant to be wider or narrower than the rear?

Looks like Steve will help you so I’ll stand aside.

Thanks @DaveR! I can see what to do but I’m on my phone away from my computer right now, so it will be a while before I can make a model to show how.

I have done a lot of research to make this. Cannons are the widest in the rear, as I am sure you know. The carriage will be 6 1/4" wide on the inside width in the front and 8 1/4" wide in the back. This is where the angle comes from. Therefore, the transom (the vertical front piece) will have this angle on the edges of these three 2 3/4" x 3" x 6 1/4" boards.

There will be a “bed board” which is the horizontal platform on which the back of the cannon will sit. Because it is horizontal it will have the front of it smaller than the back at this angle. It, too, will have three through holes to pass the long bolts to connect the upright pieces (cheeks). So this problem will exist here as well.
I have not yet attempted to draw this piece yet.

Hope this helps, thanks so very much!!
