My neighbor brought me this grape press that had been in a fire. I wish I had taken a before picture of it in tack but I didn’t. He promised me wine if I made it usable. I had a week before the grapes were ready.
I tried cutting the compound angles on my table saw and 12” sliding miter saw but ended up using the 16 inch radial arm with a 12 inch blade. It seemed like the safest way.
This is a rectangular based pyramid which requires different angles on adjacent sides. Change one dimension and every angle changes. It takes a lot of math to figure the angles. To make this come out perfect the short side needs a thicker board than the long side other wise there is a lip on the inside of the miter. This pyramid has a lip.
By the way I didn’t do the math on the angles. There is a web site that has a pyramid calculator that figures ever thing. Neighbor used the press and it worked perfect. In one year I get wine.
Edited August 2016: I got my wine.
