Thank you, and yeah I should have been more specific about the joint. I knew that the top was mitred but I meant the joint joining the base to the top. (The one that we can't see, underneath)
It's for school, so I have the tools the school provides - Tenon/Coping saws, screwdrivers, drill, band saw, hammer, mallet. Not much else.
& For the wood, I'm gonna' need two dark woods. Whichever my school can get, I was thinking mahogony for one.
It does help to phrase the question to be specific.
Many methods to attach the table top to the pedestal base. Here are a couple of suggestions.
a) Is the apron for the top solid or hides a piece of plywood? If so screw through the apron/plywood into the side of the pedestal. Alternate is to cut a rectangular hole in the apron/plywood and glue in the pedestal.
b) Glue or screw some cleats to the side of the top of the pedestal and then glue / screw the cleats to the table top.
You do not need to purchase dark wood, it is common to stain light coloured wood to whatever colour you need.
If you do not want to stain, black walnut is typically darker than mahogany, more readily available, and less expensive.
