    Notching drawer boxes for Blum undermount slides.

    This has been a little side project of mine for way too long. I bought this shaper in 08' or 09', and hadn't set it up anything until yesterday. I picked it up at an auction for $200. It just sat under a pallet rack for a couple of years until I moved into the building I'm in now, back in 2010. I'd tinkered with it a bit here and there.

    I made the red plastic top for it, (I can't remember what the product is called, the shop next door uses it here and there), a few months ago from a piece of scrap the neighbor shop had. I had to run a tap through some existing holes on the shaper deck, either it was some oddball thread, or they were just really gunked up. I couldn't get a bolt into it.

    I had to have collar spacers made by a local machinist, since it came with none.

    The dado head I had custom made by Freeborn. They normally come with a 5/8" hole to go in a tablesaw, this shaper has a 1" spindle. So they had to bore out two sets for me. Had I been thinking, (and this just hit me now), I would've just had them do the blades that I would've needed for this operation, and the other set could be set up in a tablesaw in the future just for cutting the dado to accept the drawer bottom. Dang it.

    Now a shaper typically spins at 10,000rpm. Way, way too fast for a dado head meant to go into a tablesaw spinning at 6500 rpm. I made the mistake of switching it on with the dado head in it. Scary. I covered my man bits, switched it off, and quickly shuffled away.

    My $200 Rockwell/Delta shaper didn't come with a fence of any kind. That was the last hurdle, and I just hadn't gotten around to doing it. Yesterday I had some time to kill since I was waiting on material. So I made a fence for it. It was a pain in the rear, and took all flipping day to get done.


    I bent a piece of uhmw into what would make up the structure of the fence. This is purely for dust extraction.


    Sorry I didn't get more "during" pictures, but this is it completed, sans a hole for dust collection. I just wanted to test mount it, to make sure everything was going to work out well, and to figure out where the hole for dust collection was going to go.






    I posted these pictures of it on Facebook, and a non-woodworking friend, (smart boy), asked what does it do? So I made a quick and dirty video to explain things, and show how it works.

    That's great Karl. I always enjoy your posts. You seem to have a gift for merging the creativity and shop-made innovations of a home-shop woodworker with the needs of a pro shop. Very cool setup.

    Nice solution Karl. So how did you slow down the spindle?

    I changed the drive pulley on the motor. I determined the size using an online calculator that Google found for me. McMaster-Carr had what I needed for a pulley.

    I'm a long ways from big time.

    Made in Minnesota, I like that. I need a cnc dovetailer to the tune of about $18k before I need that.

    Excellent conversion of a shaper to a dedicated notcher for your shop. Scary though, I got a little nervous watching the video ...

    My hands are never anywhere they'd get clipped. There's no way to put a guard on it, a carriage of any kind makes no sense to me from a time cost perspective, and I don't know how you'd make a powerfeed work at all.


    That drill and notch combo that chuck posted looks fast, simple, and safe. Definitely less awkward as you don't have to flip the drawer.
