help please. someone with experience or knowledge.
This is a rough, very rough not to size sketch, from top view, birds eye view of the pedestal style base IM making for my 2 inch thick oak top.
There will be 4 3x3x28 posts, one on each end, 2 in middle with a shorter one sandwiched in so I can put a very hefty stretcher in the center to support the weight of the top.
The 3x3 posts are 4 boards glued up.
There will be 1.25-1.5 inch thick mahogany ends covering up the glueups on each end of each pedestal(2)
In the drawing, again, not to size at all, I indicated where the oak side laminated to the posts will be. Im beginning to think Im going to have movement problems with the mahogany end caps glued up on the solid oak with no room for the oak to expand or contract.
Will this present a huge problem? Should I just use white oak ply and make my life simple?
Im not changing the design, I spent alot of time cutting , milling and glueing up all these posts. I have to live with my design, but Im not sure about wood expansion and I dont want to have to create some type of breadboard end for the mahogany caps, too much work, much too heavy and clumsy a piece to work with for any precise joints like that.
Again, this sketch is rough and not to size, I hope someone understands what Im asking from my sketch.(the end caps of mahogany are labelled MAH in sketch)
there will be more open space than the sketch indicates, since the posts at each end are only 3 inches wide.
I didnt want to call anyone and disturb them today, so Id appreciate any help I can get here.
And please understand, I wont change the design, I sink or swim by how I design things, so I have to deal with what I did. Id prefer to use solid white oak sides for the pedestal base, but will compromise with plywood if it makes more sense.
