Chippy anything like a harpie?
You want a sloped roof for the run off I assume?
Easy way?
you have a square or rectangle right? Nothin fancy?
Here is a pic I just did.
Just make the one cut on either end of the board at the same angle.. make em all the same length.
Use pieces of plywood or 19mm lumber (GOOD stock) to make cleats to connect the two at the peak.
Make em big and cut the peak angle after you nail the fuck outta it...both sides have to be done.
For the bottom? remember the corners of the slab where the boards were layed out?
The bottom of the board should be right on the corner if you are using the slab dimensions as the building dimensions. (no lip around da building)
Make marks, nail a length of material exactly above that mark connecting the two opposing boards and when you set them up, your upper dimensions will match your base with minimal straightening.
Run them long and cut them back to match the truss angle.
Depending on what you have, higher is better to a point...runoff?
depending on size depends on material used.
2" x 4" is really 38 x 89
2" x 6" is really 38 x 140
10' x 10' and smaller?... for the top angled boards (chords) should be 2" x 4" on edge,
larger spans = larger top boards... for anything up to 32' I would use 2" x 6" lumber (on edge)
The bottom chord can easily be 2" x 4" for any application called shed.
Nails?
89 mm for all lumber to lumber connections. 3 nails per (one side of over-lapped boards is fine).
2 1/2" for plywood to lumber
if I confuse you, just say so. I'll clear up the bits.
