That sounds like a good deal—assuming there are no major issues with it (Jet JJP-12). Amazon lists that machine for about $2800 new. A new 6” jointer and a new 12” lunchbox planer will cost about $1500.

Having the ability to edge and face joint boards up to 12” is a great benefit. My jointer is 6” and I often need to rip rough lumber to 6” or less before I perform these operations. The combo machine I assume is designed to save space (2 machines in the same space)—which would appear to be in-line with your needs.

Assuming you can satisfy the electricity requirements for that big machine (3hp)—I would say go for it.

I own the JJP12-HH and have been fairly pleased with it. I used to have a nice little 6 inch jointer and a Ridgid 13 inch lunchbox planer, so I have owned configurations similar to both options you are considering. Here is my appraisal.

The bad -

  • The obvious first issue is the changeover requirement. The JJP12 is fast and easy to change over but can be a nuisance when you are in a hurry. I have adapted by planning my lumber prep and build sequence to minimize the aggravation. It really isn’t an issue any more.
  • The second issue is the bed surfaces. They are not smooth but are purposely textured. To start with, the texture almost acted like sand paper to increase the feed effort. I had to sand the surfaces and wax them carefully to address this problem. If the machine you are looking at has been used some, then this roughness may have worn away. If not, it can be dealt with but I don’t understand why the Jet engineers would do this in the first place.
  • The third issue is bed length. It is quite short for a jointer with 12 inch width. It doesn’t bother me in the least because I don’t joint material longer than 4 or 5 feet. I would advise anyone not to attempt that, regardless of bed length, unless it is absolutely necessary to the project.
  • Like most other cast iron planers, it is difficult to plane away only a few thousandths of an inch, because you can see the infeed roller marks. My little Ridgid TP1300 could shave of 0.01” without difficulty. That isn’t as much of an issue with most people but it is in my application (CNC V-carving).

The good -

  • The reason I bought the JJP12-HH was because I needed a 12 inch jointer. It does a fine job for that purpose. Going from a 6 inch to an 8 inch planer would not have helped me very much because of the type of work I do. At one point, I used a sled and the planer to do the job but that is a tedious and time consuming effort and it just doesn’t do as good a job sometimes.
  • I just built a larger shop but the space saving attribute of the combination is really nice. My machine is fixed in position but it was nice in my old shop to tuck away the machine on a mobile base when not needed.
  • The planer is quite powerful, even with just a 3 hp motor. There is a world of difference in performance between this machine and even the best table top units. The finish might have been a little better with the Ridgid planer but I always sand at 220 grit anyway. The segmented spiral cutter head, which the unit you are looking at doesn’t have, does a much better job planing figured wood and wood with changing grain direction.
  • The JJP12-HH is much, much quieter than my TP1300, or any other table top style planer with a universal motor. Loud isn’t a problem with neighbors where I live but it might be where you live. You r-e-a-l-l-y need to wear hearing protection using any lunchbox planer to prevent hearing damage.
  • Some people report having to adjust their planer or jointer before use. I didn’t have to do anything to my machine but plug it in and use it. I might have just gotten lucky.

If there is anything in particular you are wondering about, please ask. I may have already experienced your concern.

I pretty much agree with the points that have already been addressed and they shared a good amount of info.

I originally had my eye on the JJP-12HH and liked it’s concept, though the price was out of the budget and any purchase would have been down the road quite a ways.

I was then able to snatch the Dewalt DW735X (with tables and extra blades) for $350 new on Amazon during a short-time price drop which was something I couldn’t resist. Afterward I was able to obtain a used Grizzly G0490 8” Parallelogram Bed Jointer in great condition for $750. Each are great machines and provide quality results.

Since putting the Dewalt and the Grizzly in use, I have come to appreciate having two separate machines and plan on keeping the concept, though would eventually like to upgrade the planer to a helical head and eventually do the same with the jointer. The ability to swiftly and easily perform an action without having to switch modes on a machine has been a definite advantage.

Having a longer jointer bed is much more useful to me as I generally only joint boards that are longer in length and 8” or under in width. Should I need to joint a board that is wider than 8”, a simple jig and procedure allows it to be done. (example here: https://www.youtube.com/watch?v=-bF5CRSMEHc )

In the end, it really comes down to a personal preference and either way you go, you could likely be happy. For me, while I originally thought the single machine would be best, I found that the two-machine concept actually fits me much better – and I am sure there are folks out there that are the complete opposite.

While my shop is 30’ x 40’ x 10’h, my woodworking space is basically confined to one vehicle stall. The planer is presently resting on a workmate with wheels for easy portability, though I would like to eventually build a mobile cabinet for it at some point. The jointer will handle most of my everyday needs where it is sitting, though for longer boards the built-in mobility allows it to easily be re-positioned as needed.

Thanks for taking the time to share your experiences! This has been very helpful. I have a few other questions that I’ll collect and ask later.

Have your say...
