I bought two Cuttech planers, one of which I’m going to turn into a jointer. The general idea was similar to other homebuilds online, but using dual 13” models with 3 feet infeed/outfeed tables. The whole thing is build out of 3/4” plywood. Each table is double layered ply with a 11ga cold roll steel top, and 8×1/2” threaded rods for positional adjustment. Roller bearings on end for loading long pieces The long beams are triple layered with built in spacings in the middle layer for the bolts to ride through. The jointer is stacked above the planer, and the whole thing rides on casters. The entire footprint is about 7’x2’. I’m military so had to be 120v and mobile with minimal takedown for moves.

Questions I had.

1. Am I going to regret stacking them and having to bend over to load the planer? Side to side would take up twice the floor space, and Ive only got a two care garage.

2.Not sure on the build for bearing housing. Thought about getting some pillow blocks vs building them out of wood like others have done online.

3. I designed the infeed table for the jointer as a fixed table instead of a parallelogram thinking Ill most likely just set it at 1/32 or 1/16 and leave it there anyway. Is the ease of parallelogram adjustment worth it for frequent changes?

4. The fence is still up in the air. Thinking either on/off magnets or some method to the frame at the ends.

I am big and clumsy. I wouldn’t like to deal with the planer so close to the floor. You have to decide that for yourself. I agree that the best way to achieve the accuracy you need for a jointer is to fix the infeed table and make the outfeed table and planer head so they can be calibrated. The construction is going to be extremely challenging in terms of construction accuracy and rigidity. You probably already knew that.

Nice idea for saving space but it might be a bit of a pain having the shavings from the jointer falling all over the planer. It also seems rather inconvenient to feed either really long or really short boards. For long ones, you will have the have room at both ends to maneuver around the legs. Normally, you just have to slide the board over the top. Power switch is not exactly in a convenient location if you need to shut it off quickly. Did you consider designing 2 separate bases that you can simply nest together in a similar way when not in use?

Personally, I would want to have the ability to easily adjust the infeed table. For significant warp/twist, you might want to be able to take larger passes at first to speed things up and for highly figured wood, you might want to remove less per pass than usual. I guess it depends upon how often you need to do things out of the ordinary.

BTW, I’ve been thinking about making a jointer like this too but instead of buying and dismantling a perfectly good planer, my thought was to buy a Shelix replacement head for the Dewalt 735 planer and just finding a good motor for it.

There’s a guy who posted here who made a
jointer and used 2 Sawstop extension tables
for it. Price of the iron wasn’t too extreme and
it came out looking really good.

I have done some refurbishing of vintage jointers and all of the cutterheads for jointers are much wider in diameter than the heads for planers.
Someone else might know the reason but even if you go to a shelix site, you will see the difference when looking at aftermarket heads for planers vs jointers.

Just something to keep in mind when using a planer head for a jointer.

As for the main question, there’s no way I would want to get down low to run boards through a planer like that. Large boards are heavy as it is and trying to move them around down low would be inconvenient and might be a recipe for throwing out your back.

Forgot to mention something regarding the fence.

Not sure I would go magnets. If something were to slip when putting pressure against the fence and your hand is over the blade, that could be bad.

Have your say...
