Circular Saw - better support on the other side of the angled blade
I'm going to be building a fence soon and looking to point the tops of the square posts by cutting around it at 70 degrees
From what I'm seeing online, to avoid having to levitate posts to the perfect height, most people cut the topa after the concrete is set by clamping a square 'sleeve' around the post and using it as a guide rail for the circular saw... this sounds easy enough but i then realised that putting the blade on an angle, the bulk of the support provided by the shoe is actually on the waste side of the post, and the shoe will basically be touching the pst with only 1-2 cm of the shoe.
Am i missing something here? is there a better way to do this or somehow get a shoe 'extension' on the side opposite the motor?

Screw a piece of 12mm ply to the base of the saw (large enough to provide a good bearing on the post) with the edge that will sit against your guide parallel to the base plate. Set the saw to the required angle in the fully raised position, turn on the saw and SLOWLY lower it until it bottoms out on the base plate. You could also get the angle you want on the posts using a reciprocating saw or the just use a normal hand saw if you have the energy and stamina, its murder on the arms and shoulders.

Have done what it quite a few times, basically as you have explained, yes you are relying on the small side of the foot plate.
But mark out well keep above the line, an if need be touch up with a belt sander if your brave, or use a file.
The Option it to use caps on the posts.

Hi DC. The process you have described is correct and you actually have plenty of support. Assuming posts are 100 x 100 or more, the saw blade doesn't cut all the way through. Even the 4th (last) cut is still supported for most of its travel, just let the saw blade stop in tbe cut as you come to the other side of the post. When you say 70° do you actually mean 20° from the horizontal? As in a shallow peak. The traditional peak for pickets was around 60° but only some circular saws can cut 55° at best, and at this angle you will be finishing off the cuts with a handsaw. A reciprocating saw will require a lot of sanding to clean up faces of cut afterwards.
