What throat plate is this

[thowe]

I picked up some BT parts recently and had never seen one like this. Anyone recognize it?

Looks to be one for a Ryobi BT3100.

that's the throat plate that came with the saw on later models.
Finger lift hole, spring loaded tangs for retention (w/o screws) in the front.
Not sure but the two spring fingers at the back, did they go under the head of a FH screw to retain the rear of the plate? No visible fasteners.

More specifically, appears to be a dado throat plate.

sorry pappy, I'm sure that's the throat plate for the regular blade. Its that wide to allow a 45 degree blade tilt. That doesn't mean you can' t use a skinny dado - I've put a 3/8" box joint dado in mine. IN addition, The slot goes all the way to the back to allow for the riving knife. For a dado you wouldn't have that since you don't use a riving knife with a dado.

I believe that is the standard throat plate of the last of the BT3100s. Mine is similar except no spring loaded tang, it was held in by a screw. Yes the tabs in the back are held in by screw heads beneath the surface... Mine you slide the back tangs on the screws and use one screw in front to hold it in place...

And no, it isn't a Dado throat plate, but it is close enough. It sure isn't zero clearance!

What is the surface it is resting on? That looks like it might be an air hockey table... Makes me want to grab some friends a pitcher of beer and a pocket full of quarters!

Could be the Ryobi air flotation table.

That's the first time I've seen that style TP. My 21829 is similarly shaped, no clips or thumbhole, just a flat metal plate with three holes for screws, two in the back and one up front.

That appears identical to the stock throat plate included with my BT3100-1, which I bought new in June 2004.

Loring: yes, those two fingers fit under flathead screws to hold the far end down. The spring clip at the end with the finger lift hole holds the near end down, and can be backed up by a screw through the small hole that's adjacent to the clip.

Thanks for the responses and how it goes in. I thought it may sit on the rear screws but wasn't sure. My BT is much older so I hadn't seen this one.

Looks like I have some more tinkering to do on the saw.

That's the original that came with my saw. The one on the right is the original dado plate. I have a drawer full of ZCTP's, but I do use these occasionally. I use the one on the left for non-45 degree miters, and the one on the right for some odd sized dadoes.
