Yiyong Leng's homemade jointer

Matthias:

Hello again! :) I bought your plans a long time ago, until now, I have finished my homemade jointer building. Thank you for the genius of your design so that I have the courage to complete such a complex project step by step! Your plans are excellent both in drawings and 3D models.


I took apart my previous thickness planer and reused the cutter head, bearing seats, induction motor, pulleys, belt and switch from it.


According to the shape of my bearing seat, I think of a best way to put it on the jointer's frame. There is a block of wood be placed between two feet, so the bearing seat can’t be moved right and left. And the foot has a M8 thread hole on both side bottom, I screwed a short thread rod into there through the wooden frame, then I locked it with a nut. There are two boards behind and up against the bearing block, I think it's helpful to increase its stability.


When I turn the shaft, I find it's not too smooth. I think this may be caused by the two bearing seats are not parallel enough. I inserted two thread rods for parallelism adjustment with nuts. There is a pair of nuts on each side, one is used for adjustment, the other is for locking. So two thread rods have four adjustable positions for Parallelism adjustment. and finally, it becomes smooth.


The reason why I didn't make wooden bearing seat is that I can't find available high quality plywood at all in my city. The body of the jointer and the in/out feed tables are made out of cheap plywood.

Frankly, I painted the jointer after finishing the assembly to hide the ugly materials actually. I think it does not affect the actual use of. It looks like a test of what a poor material can do.



The way to tension belt is to move the induction motor horizontally, and then lock the sled of motor by tightening the blot from the bottom.



I added a half round nut be touched the table for reducing friction when the guard returning.


My fence was cutted from a hollow inside MDF floor( I picked it from a dump by the roadside ), I put a few of plywood into the back of the floor for better screwing.


After jointing, the board is to be flat enough. And also the edge of the lumber, I think it's no problem with edge jointing board.


I have a vedio for showing the process of this jointer's making
