Hey, Folks. Anyways, when the blade is set at 45* it nicks the throat plate upon startup. Obviously not good for the blade or the throat plate.
It seems too be a problem with the whole motor alignment. I measure between the blade and the fence and I get a difference of about a shy 1/16". The fence is square. I first thought it was a warped blade, so I changed in a new one. Still nicks on startup. The last time I went too Home Depot I looked at a new saw on display of the same make and set the blade at 45*. On the new saw the blade is pretty close too the throat plate as well.
Been busy as hell lately and really haven't had the time too get in there and figure this out. Kinda' hoping maybe someone else might of had this problem and had a quick fix for me. I hope it's not a bent arbor or something like that.Thanks for any info.

This is not an unusual characteristic. If your throat plate is anything but metal of some type, you can lower your arbor all the way down, set your degree of angle to max and if it has an adjustment, adjust it so you get as much deflection as it will give.
Before you did that you should have put on the widest kerf blade you can find. If you have a 10" saw you can buy a 10 1/4" wide kerf blade.
Now raise your arbor with the saw running and it will grind off just enough material that your thin kerf blade will no longer make contact once you readjust your deflection og angle to exactly 45.
Make sure you don't allow that extra 1/8" of blade on each side make contact with anything harder than it is.

If you throat is metal, you are going to have to either get a poly throat or buy a set of zero clearance inserts for your saw. They come with no slot. You have to use the procedure I just outlined excpet no oversixed blade. that way you have an inserrt for 90 cuts and 45 cuts.

If you have a metal throat and insist on staying in the dark ages you can take it to a machine shop and they can open it up a little for you.

I have various insterts I made out of Osage, and you could do the same. Maple and mesquite would work just as well.

Most metal throat plates can be widened pretty quickly with
a regular steel file. Most plates are pretty soft.

Thanks, guys. I considered grinding off a little bit too get the clearance, but figured the saw is not supposed too hit the throat too begin with.
Awesome info I'm gettin' hooked on this site.

I have a 1947 Oliver 270D. I think it is made from melted down Sherman tank parts. Nothing soft about it!

O.K., I'm a 'tard. Fixed it in 5 minutes.
