Zero clearance - sussertown - 02-22-2018
I'm having brain freeze. If I make a zero clearance saw table throat plate at 45 degrees what happens when I raise and lower the blade.]

Blade will bind up

You'll be fine, I keep one cut at 45º. You just have to make sure your blade is at 45º when you raise and lower it.

But it won't be a zero clearance on the next cut.
I have two throats. One for angle cuts. They replace easily on my Delta.

If you have a cabinet type table saw the blade rises and lowers along the blade axis. Tilt the blade at 45 and raise it and see if it extends along the 45 degree angle. If it does, it will not bind when changing the elevation. Roly

You are not accounting for the thickness of the throat plate. The axis is at the surface of the plate, not any deeper.
You will have to cut another slot into the throat plate at the 45 degree angle. If you tilt the blade with your pre-made zero clearance throat plate while the blade is raised you will put the blade in a bind.
Its best to have 2 plates.

Like Cooler, I have multiple ZC plates that I made. Making one is just as easy as six...six just takes a bit longer.
One for 90*, one for 45*, one for dados, and a few extras for "off" angles or other dado sizes.

May be I misunderstood the question. If you have a 45 degree zero clearance throat plate installed, you can raise and lower on a cabinet table saw without binding. If you install a 90 degree throat plate with the blade lowered all the way and raise the blade it will cut a new slot at a 45. It will no longer be a zero clearance plate. I am not sure how the blade raises and lowers on a contractor type saw. Roly

Yes it is, i only use for 45º cuts, and the blade has to be fully retracted to remove the insert.
