Lives Up to Expectations
I've had this for almost a year, and it's lived up to expectations. Understand that this combo is a space saver, and it's foremost purpose is to utilize space. Is it as good as a long-bed jointer and a 20" four post planer? No, but if you could fit and/or afford those you wouldn't be wasting your time with this machine. There are going to be some trade-offs, but I haven't found any other machines (at this price) that can deliver like this one.

I'm a garage woodworker, so space is absolutely limited and I'm constantly thinking about new ways to utilize space. The JJP-12HH does just that. This is my first jointer and an upgrade from a lunchbox planer. I haven't had any alignment issues, and the table was coplaner right out of the box as advertised. The fitted with digital readout, and I'm within about 3/1000 which is good enough for me. I never used the factory scale with my old planer either, and the digital scale is cheap and highly recommended. Yes, you have to bend down to access the planer adjustment wheel, but that is the trade-off of having a combo machine. I don't know how else it could be designed. Transitioning takes 30 seconds. If that's too much time to waste for you, again you probably wouldn't be looking at a space-saving design like this one.

Now that I've seen the helical head, straight knives be gone. Easy to replace, and I think any helix style will work. Another thing I've found with this machine is that the drive motor, belts, etc. are easy to access as the back is one removable panel.

Plan on plenty of degreasing when you take the packaging off, but as with any cast iron protect it with T1 or something comparable immediately. You will not be able to move this by yourself, so buy the mobile base whether you think you'll need it or not. I got three friends to help me lift it onto the mobile base. I also recommend the Dust Right Quick Fit attachments. They make the change over easier.

If you're pressed for space I highly recommend this product.

Well Designed - easy to understand and align.
My JJP-12HH needed to be dissambled to be taken down two flights of narrow stairs. To my surprise and relief, it was not difficult to remove major parts and reassemble them.

Alignment procedures are in the manual and straightforward - requiring only common hand tools and a straightedge.

Jet Planner/jointer
Overall I'm happy I went with this unit over trying to cram two separate machines into my limited space. The conversion from jointer to planner is quicker than I expected it to be. The Helica cutterhead is phenomenal and having a 12" jointer has been very useful. Only downfall to me is that a 12" planner is slightly undersized for many of my projects. If my bank account can recover from this purchase I will look into an oversized drum sander to help make up for the undersized planner.

Great machine and compact
The machine arrived well crated so no need for realignment. Everything was there except one hex nut that is a sop when jointer table in up position. It was mailed quickly to solve that problem. It is just right in my compact basement shop. I loved the fact that it was 15% off and free shipping over Thanksgiving

Great value small footprint
I have a typical weekend warrior workshop in my 3rd car garage so space is a premium. I tend to do everything from remodeling to small boxes and everything in-between. I was considering the Hammer and Mini-Max but when jet put on the discount for black friday I jumped on this model. The Helical Head rocks! I didn't think I would be one of the ones saying something like this but it does have a better sound signature then straight blade models. More importantly it creates smaller shavings for a better finish and with my DC unit it seems to do a great job getting the waste away. Shipping was a bit of a pain since I live at the end of a dead end cul-de-sac (not a -1 for the product but a consideration for any large shipments) The company Rockler chose as the freight company was very easy to work with and met me around the corner and placed the item on my trailer for me. This actually made it easier since I could back in my driveway right up to the garage (freight companies are not allowed to drive on your driveway). My only complaint with the unit has to do with the adjustments to get the tables co-plainer. There is a combination of set screws and hex bolts to adjust the entire setup in the upper left hand corner of the in-feed table. Perhaps I just had a poor execution plan but it took me the better part of 4 hours to get this item really dialed in and I do have an issue with repeatability due to the locking cam mechanism to fasten the table down to the base. That being said I believe this will be true with any of the combo machines and perhaps Jet would be doing a big favor to its users for a little more clearly written instructions or better yet a video with a sample of their recommend leveling technique and tips and tricks. Once I got everything ironed out within 1/1000 of an inch this thing performed like a champ. Initially the planer was a little difficult to feed but I think I was just use to my worn out in-feed roller on my old planer as the first pass wasn't deep enough to make a cut and once raised the table I pushed a little harder to start the feeding it rolled through like a champ with a nice cut depth. All in all, after a couple of weeks of running everything I can through it it seems to be holding up well. When I change the table back from planer to jointer I find my self rechecking with a depth gauge to ensure the out-feed table is still level to the blade which is why it gets 4 stars and not 5, (but perhaps I am very picky as it is always very close and in the couple of times there was a variance all I had to do was push or pull the lock lever and it will level right out.

Great Function, Fit and Finish Disappointing
If you are reading this you probably are considering this machine for the same reasons I did. Space savings, combination of planer and jointer, reasonable price. In summary, I am very happy with the function of the machine, but the fit and finish is extremely disappointing. Next to my Sawstop PCS, this looks like a used Honda sitting next to a new Maserati.

Ordering this was easy, it came within two weeks of placing the order to Southeastern Minnesota. I set up for a gate delivery, the usual challenges with this arose, meeting at a certain time, not being able to wheel it all the way down the driveway secondary to snow, Etc. These were expected. It comes packed in a crate with the plywood box around it. It essentially unpacks and can be used almost immediately.

***You will need to buy a 240 V plug and fit this on to the three wires coming from the cable out of the back of the machine. Apparently the variability in different plugs lead jet to leave this up to your discretion.

Inspection of the machine was a bit disappointing. I have nothing against China, but the trademark made in China (for the lowest bid) findings were all over the machine. This included beading of the welds, spots of rust here and there, one of the fly wheels for the planer already had a fair amount of rust on it, parts of the metal were scratched, the decals were peeling away in certain areas, rough edges to the infeed and outfeed, pain missing/touched up in some spots. etc. Perhaps most importantly, the connection between the cutting guard and the machine was fractured and worsened immediately upon the attempt to dial the jointing space farther open. This required a call to rockler to replace the part. They were great about it, but the design is questionable and the part is $275 if it breaks again.

After fashioning the plug I moved the machine with the help of a friend directly from the pallet to a sawstop ICS base. I cut a piece of plywood to match the base of the ICS and the Jet fit nicely (at 90degrees, but still). This is a really nice base and is super reliable.The ability to hydraulically drop the machine onto the floor versus locking casters is super helpful and it will be around long after this Thing dies).

After positioning the machine, I cut several pieces of 8’ poplar into 3’ x 3” 3/4”pieces. This was done from rough sawn wood. The machine works very nicely, although it was a bit scary to use without that new blade guard which is on back order. Get ready to put that dust collector on your wish list, it creates and collects a lot of dust (as most planets/jointers) do. To get things to cut correctly I did have to square up the infeed and outfeed with a straight edge and the manual, But this was easy enough. The helical cutterhead cut beautifully, no snipe, no tearout on either function.

Switching between jointing and planing is easy enough, though you have to Drop the planer bed to flip the dust collector ****AND YOU HAVE TO RAISE THE PLANER BED AGAIN TO GET THE JOINTER TO WORK AGAIN (at least on my machine). This is a lot of up and down, but still the best design for a combo machine. The needle for plane thickness is accurate, but many folks (and myself) add a wixey digital to really dial it in.

Overall, 4.5 for cutting ability/use, 4.0 for design (for a combo), 3.0 for the fit and finish, 2.0 for the durability (cutting guard broke in 30 seconds). If you are a hobbyist looking for a big jointer, or just something to take “the next step” in your woodworking from a benchtop to a stand alone, this is a great machine. If you were making cabinets or doing fine woodworking for a living, hold out and buy separate machines of better quality. I doubt this thing would hold up to chronic daily use well, and having to drop your planer bed up and down to joint will drive you mad. I like it for my purposes, But one day I will likely get a higher capacity planer and just use this as a jointer if this hobby continues to expand.

Does Jet have a mobile base that fits this machine well? Is there another quality mobile base that would be recommended for this machine?
Karen K on Nov 18, 2017
BEST ANSWER: Don't know if Jet has a mobile base, but I used the Rockler All Terrain base, which is very sturdy for this very heavy machine. The machine moves around easily with the mobile base and stays in place when the wheels are locked.
Online manual says it doesn't come with a plug just a cord? Is that true? If so, where did you find the plug end?
John W on Mar 18, 2017
BEST ANSWER: John,
That is correct, no plug. As it is a 220V I think they leave the plug end to the customer as there are a number of different plug types for 220V.
I found my plug end at my local Home Depot. You will want to match your plug end with the same style as your 220 receptacle. Home that helps, Kent
