Edge Trimming Question

[John Myer]

Need to cut both edges of long 1x6s to fit peak of sloped ceiling. Included angle for both edges would be 30 degrees. What method would you recommend? Doing this on construction site, so portable tool option would be best.

[Jamie Buxton]

Crude and fast: circular saw freehand.

A little less crude: circular saw with an attached rip guide.

Precision: router with a 15 degree bit, with an edge guide.

festool saw with rail would make this a snap - done this a number of times on both ply and studs
