Trim rafter tails after placement For a good straight fascia, add an extra inch or 2 to the tails of all your rafters (total length). After they're up, you can flick a line to mark and trim the tails in a nice straight line, to make up for any ridge warp or marking, cutting and fixing errors.

Roof Angle

Circular Saw Bevel Setting Hip and Creeper Side Cut Settings If using a Circular Saw or Compound Miter saw, set saw bevel angle to 45° to obtain Creeper and Hip side angles.
With the saw bevel angle set to 45°, cutting hips and creepers at the plumb cut angle will produce correct side angles.

Circular Saw Hip Cuts To mark and cut hip plumb and side cuts with a circular saw - Print a Paper Template (easy + accurate) OR:
1: Mark the end plumb cut angle line ( back from square) on both sides of the hip. This is the pointy end. (Don't cut yet)
2: Measure back from this line and mark a second, parallel line on both sides of the hip. (This is the line to cut along)
3: Set circular saw blade tilt angle to 45°, cut 1 side along second line, with blade tilted toward pointy end, then flip and cut other side the same.

DON'T BREATH THE DUST If you're cutting concrete, stone or ANYTHING and there's DUST - DON'T TAKE THE RISK
Don't cut it, or cut it wet so there's NO DUST - Silicosis Sucks

How should we spell it?
