I would buy a dado stack. You can make that in 2 overlapping passes. Should be easy enough. Clean up with a router if it needs to be perfectly smooth, but if it’s the inside then it doesn’t need to be.

If it doesn’t need to look good such a cut
can be made with 2 setups on the table
saw, one with the work flat on the table,
the second with the work run on edge
against the fence.

A dado blade is a good way to do it too,
especially if you want it to look good.

I’ve never seen a rabbet so wide in a picture frame. The board will likely bobble as you exit the cut, because you’ll have such a narrow ledge to support the board. I usually make rabbets 3/8”-1/2” wide for picture frames.
I would look to redesign the frame if possible.

If you must build them this way, start with extra long stock and use push sticks. Then you can remove the bobbled end when trimming to final length.

Sometimes to think small you have to start thinking big.

Use your TS with a dado stack, but start with 1×2 1/2 or 1×3 stock. Cut the rabbet as a tunnel so you always have a solid point of contact on both sides of the dado blade.

Once you have the rabbet, flip it over onto the wide side and rip off one of the legs, leaving you with the L shape you want, but still with all of your fingers from not trying to hold it steady.

If you have a buddy with a jointer, this would be fairly easily done as well using the rabbeting ledge on the jointer, but it would take a few passes.

The other way is to use wider stock than is required. Route a channel or use a dado stack to make a channel and then rip the extra off.

Edit: What Mike said above. Sorry Mike didn’t read your post :)

This is the method I think will work best. Except I will use 1×4 and run the board across the dado twice, so that I have two uniform “legs” and then clean out the middle. Then I will rip down the middle and the two halves will be two frame pieces. (“Ripping down the middle” is probably not the ultimate solution, better to set the fence and rip with only leg against the fence and then rip the other side with the leg against the fence so that I am effectively cutting a bit out of the middle, leaving two identical halves.)

Thanks all!
