Well, had the one pine scrap with a groove along the bottom edge, much like the side of a drawer......hmmm, these would normally get a dado at one end, to house the back of the drawer.   Sooo

 

Off to the shop!    I grabbed a 1/2" wide cutter.    reset everything on the plane, more or less.    Pulled the spurs/nickers....one needed a few trips along an oil stone.   Both are as sharp as I can get them.  Installed with the cutter lobe down.   Set the 1/2" cutter into the main stock.   Waxed everything on that side of the plane.  Slid the sliding stock over, to the edge of the cutter...

I had both depth stop lowered...only need the one.  Set the fence about a 1/4" or so from the cutter.  Another look?

You can see how the spurs stick out.   Now, as with any plane that uses spurs/nickers...the first three or four passes, you are pulling the plane backwards.    That allows the nickers to cut the grain's fibers, and makes for a better edge.  Once that is done, then try a forward pass, or two, to check on how the iron is cutting.   Use as shallow a cut as you can....

On the drawers I make, I usually clip the corners, more to aid in installing a drawer into a case.   yep, I get those chipouts when cutting a dado here with other tools.   One has to keep the fence tight against the edge, or the cut will wander around a bit.   You can add a strip of wood at the far end of the dado, and let it blow out instead of the "good" part of the wood.   Takes about as long to cut one dado, as it does to set up the plane, but, once it is set up, you can do an entire run of drawer sides, without any fussing around with the plane.

Not too bad.  Those clipped corners?   I can either cut them with the bandsaw, or, my "new" mitresaw...

Finally have the Stanley 358 set up in it's new home.   Had to move things a bit closer to the front edge......that be a LONG saw sliding around there. 

 

Next time?   Well, this plane also does Fillister work.    I don't really need any sash work.    As for slitting....meh, we'll see.  7 planes in one.....I have done..Match, Groove, and Dado so far.  I just might get used to this little plane..

Awesome plane!
