I'm pretty much self taught when it comes to trim carpentry, and even though I've asked many more experienced trim carpenters this question, their method isn't much different than mine. What's a good repeatable way of cutting sharp (55-75 degree) angles on a job site? I usually use a shim against the fence to compensate for angle past the max of the miter saw. This works for the situations I usually find myself in (mostly paint grade house trim, nothing fancy, and never a miter, usually just butting an angled wall or something) but I was wondering how you guys that do really high end work accomplish this if a job is expensive hardwood molding and involves many or at least multiple miter cuts where the profile must line up correctly.

From contributor W:
We make a jig and it starts with a piece of thin plywood the same size of the chopsaw table. On the plywood attach a fence to the right and left of the blade where you set the fences - it depends on the angle youíre looking for, maybe 20 degrees off the blade. Now your moulding end will be out towards where you stand. Move the blade left or right to dial in the angle you need. Itís simple and safer than shimming off the fence.
