I have a job building a screen for a roof terrace deck. The screen covers a mechanical bulkhead with AC condensers on the roof of the bulkhead. So far I have all my layout done and the upper section is done. The wood is cedar.
The lower section will be more fixed panels and 2 small gates (like a french door) to allow access to the steel door in the bulkhead. Each gate is about 90″ × 25″.
Anyway, I’m considering pulling out all the stops and using draw peg joinery for the gates, so today I made a little mockup to see how it works. I never tried draw pegs before.
First I started by ripping a 2×4 to 2-1/2", which is the width of the frames on the fixed pieces. Then I made a mortise and tenon joint. Then cut some 3/8 poplar dowel and put a point on each peg. Then I drilled two holes all the way through for 2 straight pegs. Then I drilled another hold for the draw peg, but stopped at the tenon. Then pulled the joint apart and drilled through the tenon about 1/8" lower than the holes in the mortise, then finished of the drilling of the mortise in line with the first hole. Then assembled and hammered the pegs in.
I don’t know if it’s the lumber or if I’m spacing the draw peg hole incorrectly, but the top of the tenon broke when I hammered in the draw peg. When that happened it pushed the joint apart too. I cleaned out the broken pieces and was able to close up the joint some.
The whole thing is not as rigid as I was expecting. There is some small movement if I tug on one side. That leads me to believe in doing the whole thing wrong. Maybe wrong peg locations? Maybe it don’t need the other 2 pegs at all. I don’t know.
