Jacob, a great ‘first’ router plane is called an Old Woman’s Tooth and you can easily make one yourself. All you need is an unused, neglected, decrepit Allen wrench a block of wood with a hole in it and a set screw. You can put spoke shave handles on it, or draw knife handles or even knob and tote.
It’s one of the easiest planes you can build and performs almost flawlessly as long as you keep it sharp.
I’ve even made one with a piece of 2” angle iron (actually cold rolled steel) from and old bed frame that worked great until I lost it somewhere.
This would be a great project for you and your son to make in the shop and both of you could learn some awesome stuff at the same time!
