Framing square can be complicated enough. In this case, a client asked me to build a ramp with a modest radius to make it easier to access in their golden years. I laid it out like a parabola, first on draft paper, then creating a grid on a 2×12″ board and transferring the proportions. A thin strip of decking pin-nailed onto the face helped create a smooth, even line.
Next, I cut this piece with a jigsaw and used it as a template to make a total of 6 joists. These were then clamped up with pipe clamps and planed/sanded flat and perfect. The back (deck edge) was cut flush using a circular saw after being marked up while clamped, and the blocking was added, nailed through the sides when possible and toenailed otherwise.
The final piece was mounted into place with ledger locks, stair strapping, and corner brackets for a hold that will last a lifetime!
Now if that extra decking will finally be delivered, I’ll finish up!
