Just finished 100 22x22" shop drawers of various heights with the Whiteside bit (1/2 ply, B/C, normal big box quality). Comments:
- Nice joint with occasional tear out. Use a sacrificial pushblock to avoid tear out on back of cut. Typically the tear out was in the middle of the cut, so it glues up ok and isn't visible.
- Easy glue up. I used ratcheting straps with outside rounded-over corner block (x4), pulled up nicely and completely. Was able to glue 8 drawers at time (I'm cheap, only 8 ratchet straps, which have gotten spendy).
- Strong glue-only joint, looks nice, covers the drawer dados completely.
- Protip: the Rockler Silicone glue brush is genius for this, quick and easy glue spreading, easy cleanup, even if you 'forget'.
- The Whiteside bit is a 2 setup bit, one for fronts and another (fence only) for sides. Not a huge con as the depth is the same for both.
- Tedious to rout each side of all joints (100 drawers x 8 = 800 router passes)
