I think I might be getting hooked on making my own tools. I cut a lot of rabbets and dados on the table saw, but the the dado stack usually leaves ridges. Then I have to use a chisel to clean out the channel. The easier way is to use a router plane. I had been wanting to get one for sometime, but they aren’t cheap. And as a woodworker, I thought why buy when I can build it. After a little research on the web, I came across Derek Cohen’s website and so the build began.
The majority of the plane is constructed of walnut with a piece of hard maple on the back. The iron is a standard router plane iron from Lee Valley. I finished it with Tung Oil.

As you may have noticed there were two blanks in one of the pictures. I made two of them, one I kept for myself and the other was for a tool swap I participated in over on the forum.

Good work. I think that looks better than the one I bought.

Nice tool. You’ll appreciate it more if you make it you self. I also made one of them and it sure comes in handy for things like hinge mortices….........Jim

Very nice project Thomas, thanks for sharing this build with us. I could really use one of these router planes myself, so maybe this will be the inspiration I need to do it. Your video was very well presented and enjoyable.

TNX for this iteration of this useful tool mine was slightly different but I like the way you attached the blade.
my next one will use this method.

+1 on hooked on making your own tools – its amazing the level of customization you can manage when you simply design and fabricate it yourself. Just finished a mallet, and a scratch awl, and working on a walnut/mulberry hacksaw, its addicting

What a fantastic tool you’ve made! – I’m gonna have to make one now ;)

Looks 10 times better than the old router plane I purchased on Ebay.

Usually I find wooden router planes bulky but that one looks really nice and agile. Nice work.

Thank you everybody for the nice comments. It was a lot of fun to make and not very difficult. I encourage anyone to give it a try. I think it will make a nice starter tool for those interested in building their own.
