Here are several pics of the Jet planer/jointer combo machine in planer mode. Conversion from jointer to planer is really very easy. Loosen 2 lever locks, lift the beds ( which move in one piece with fence), swing dust shroud into planing position, then finally activate the feed rollers. The only time consuming part (20-30 seconds) is raising the bed up to desired position. The bed has to be lowered to about 6 inches for the dust port to clear, so to plane 1 inch stock, you have to raise the bed 5 inches or so. The bed was not quite parallel to the knives from the factory, but easy to adjust to plane to a uniform thickness. Dust collection was very poor initially, until I learned that my 5HP cyclone tends to pull closed an internal baffle, but after placing a small bolt to hold the baffle in place, the dust and chip collection is excellent even taking very thick passes. Given the time for raising the bed, the dust collection issue, and the fact that the planer is only 12 inches wide, I gave the planer mode a 4 out of 5, but actual function seems to be a 5 out of 5, no snipe and a very uniform surface.
This machine is a quantum leap from my Dewalt 735 planer (much, much quieter) and my Jet 6 inch jointer. I really appreciate the space savings (both the space of the machine itself and the required work space around it for stock to pass). I feel that is an excellent value at around $2000, as I would have never justified the cost of a 12 inch stand alone jointer, but some might argue that a 12 inch planer is on the small size.
Overall, I am very happy with this addition to the shop.

I have been considering a similar upgrade. I have a Dewalt 735 and a 6” Powermatic Jointer. This Jet is certainly on top of the list. I’m also considering Laguna’s new combo units. I’m going to give it a little time and see how happy people are with them. If money was no object, I would either buy a Mini Max or Felder.

Hi Gary
I presume the baffle is in the swing dust shroud? Is there any way to show where you put the bolt? What type of mobile base are you using?I have a 5 HP cyclone and am considering getting one of these machines. Thanks!

Tom,
If you look at the first picture, you will see a small black chain connected to the on/off switch housing. Follow the chain up to the bolt sticking out of the dust shroud. There are two holes present, if you place the bolt in the lower one, the internal baffle can not move up. This trick really works. I am using a HTC 300 mobile base with some 1/2 inch BB plywood. I will not be moving the machine often, but I may need to shift it around occasionally for longer stock, cleaning, etc.

How did you determine the planer beds were not aligned with the head? If I go this route I would love to know how you checked for this…
Thanks,

Chris,
Nothing magic, I just planed a board. I measured that one edge was about .001 thicker than the other, indicating that the planer bed was not quite parallel with the knives. Before making any major adjustments, I may try locking the bed height to see if that changes the bed position.

Sounds like a good solution for my shop, don’t have the room, budget or room for both… and I’ve put off a couple projects for want of a jointer. (Yeah I know I can use planes or make a sled for my router…)
