Rob Cosman's Drawer Bottom Plane
When I was making custom furniture I made and used my own planes to cut drawer bottom grooves. The plane was easier and more precise than using a machine. When I started teaching I made a few planes for my students and when I featured it on my drawer making DVD I began to get a lot of requests for them. Now you can have one too.
This plane cuts a 1/4" groove 3/8" up from the reference edge and 1/4" deep.
The body is made from Birch or Maple
The blade is 3/16" thick and 1/4" wide.
The iron fits closely in the mortise to minimize set up time.
Easy to set up: get the blade close, set the wedge hand tight, tap the blade to the desired setting and seat the wedge with a light tap.
Tapping the rear of the plane will release the wedge.
Best of all, nice and quiet!
Right out the box with no prep, made grooves for box I am building with little effort. Plane was sharp and very accurate. Professor Cos was right on the money with this plane. Think I will get left-handed one soon. Thanks for your effort Cosman team, well done.
Works like a charm the only problem is it does not remind me to cut the groove on the proper side of the drawer piece.
Very nice and works great. Much better than using the table saw to make the groove. I make the groove with this plane first and then layout the dovetails accordingly. The maple syrup was a real treat too.
These are a great set of specialty planes to have. Why the pair and not just one for hand dominance well I like to always with the grain and although it works with the grain either way, it's easier and you get a btter finish with the grain. Very well made, The plane blade is good quality steel, I didn't even touch it on the stones before trying it out. It cut great. It's the perfect tool for the job. I highly recommend it if you're using another plane for the task. I especially like it being set up 3/8" from the bottom. easier to hide in half blind dovetails
Have only “tested” it on oak and pine. It worked great right out of the box. Love it!
