Very useful in home workshop if on budget
Posted March 2, 2014
Unlike others, mine went together and works well. The outfeed table requires a little trial and error adjustment, but one right seems to have held the alignment. Blades a little tricky to adjust, again needing trial and error, but once set seems to remain aligned. I have had no power issues, even with hard maple, but can clearly hear that the machine is working hard. Waste ejection not very good, but hooking to a shop vacuum helps. I also must occasionally use a blower to clear the waste chip, or cut quality deteriorates.
For an old guy on SS, it is this or no jointer & planer at all. I am happy to have this, and it works fine in my garage workshop. It is clearly not up to production or jobsite duth however.
The Jet 10 inch jointer-planer is...
Posted March 15, 2011
The Jet 10 inch jointer-planer is not capable of properly jointing a board. The in-feed and out-feed tables are not co-planar. This is not a small deviation from parallel planes, but a LARGE one. The out-feed table slopes away from the blades, and the in-feed table slopes up toward the blades. I contacted JET and was promptly emailed the instructions for adjusting the out-feed table. The in-feed table can not be adjusted. The adjustment on the out-feed table diminished the slope by about 1/2 of the distance it was out of position. Obviously, this did not fix the problem. In reality, there isn't really an adjustment built into the out-feed table. Jet is simply using the fact that the holes bored into the out-feed table sides, two on each side and which are used to attach the table to the bed of the jointer, are a bit loose. The four bolts two on each side are loosened, then the end of the out-feed table is lifted up, pivoting the table around the two bolts nearest the blade and sliding the other two sloppy sized holes upward around their bolts. The bolts are then re-tightened to complete the "adjustment." Unfortunately the end of the out-feed table would need to move about 1/2 inch to correct the problem, and the "adjustment" yields only about 1/8 to 1/4 inch movement. As this was not a designed mechanism for adjustment, but rather a stop-gap utilizing sloppy machining, the method is NOT included in the manual. It seems apparent that this is a design and/or manufacturing flaw. If all of the machines have the bolt holes in the same position, then none of the machines could possibly properly joint a board. It is very disappointing, as the idea of a small footprint 10 inch joint-planer was very attractive, especially at this price point. We will have to wait for another company to do this, or for JET to re-design this item. As it stands, it will not joint boards.
I read reviews on this machine...
Posted October 12, 2010
I read reviews on this machine on multiple sites before I decided to purchase and came to the conclusion that it would serve me well. I had what I thought to be realistic expectations from this machine. I had expected a machine that would work well for boards up to 5, maybe 6 feet long. I expected it to be under powered, but usable. Many reviews spoke of the difficulty of getting the jointer tables coplanar. I planned on setting the jointer to take a 1/16" cut and leave it there all the time to avoid the tables coming out of alignment. I knew that switching form jointer to planer would be a bit annoying, but I was willing to accept that. All in all I really expected to make some realistic compromises with this machine, but the size of the machine and the price made me decide to buy it. I received the machine and started putting it together. It went together quite easily and took about 2 hours to assemble. Once I started to set up the machine I started having issues. The knives needed to be set. The first was easy to set with the jackscrews used to fine tune the height of the blade. Upon trying to set the second knife I started to have issues. The front jackscrew would come all the way out of it's threads before the blade was high enough. I was able to get the blades set, it just took a little more messing with than it should have.I noticed while adjusting the infeed table that if I grabbed the far right end of the table, I could easily move it up and down about 1/8". I tightened the adjusting knobs for the infeed table on the back of the machine, but couldn't seem to get one of the rods that holds the infeed table tight. I removed the front cover from the machine and used a wrench to tighten the rod from the front. This started to help, but the rod snapped before the table was tight. Upon inspection I found that one of the square washers that aligns the infeed table in the diagonal slots that keep it aligned was installed crooked preventing a large bushing from seating tightly as it should. I emailed Jet about the parts assuming that with a new rod I could get the machine running. I also asked about the issue with the jackscrews. Their tech had me measure the distance from the top of the outfeed table to the cutterhead assembly. The outfeed table was higher in front than in back making it necessary to set the front of the knives a bit higher than the back. I can only assume that the outfeed table was incorrectly machined as Jet sent me a new outfeed table as well as the replacement for the snapped rod.I started to try and reassemble the machine, but soon found that replacing the outfeed table requires taking the machine almost completely apart. Also while I was working on it, I found that one of the springs that provides tension to the outfeed roller for the planer was loose. I was going to reattach it, but the cast piece it was supposed to connect to was broken, so I couldn't.At this point I requested Jet send me a replacement and I would ship them back a pile of parts as I felt that I shouldn't have to spend this much time repairing a new machine. They said I could either talk to the retailer I bought it from, or send it to them at my cost to be evaluated. I decided to return the machine and go ahead and spend more for a separate planer and jointer.This machine is a great concept, and in its defense isn't underpowered too badly. The planer works great and leaves a better surface than I expected, but as a jointer it is completely useless. The parts are so poorly designed and poorly assembled that getting it to make a straight edge seems like it would be a constant battle. It seems like if Jet had aimed for $500 price point they would have been able to make a machine that would be worth well over twice as much as what they are offering right now for only a slightly higher price.
The design and precision of workmanship...
Posted November 17, 2009
The design and precision of workmanship of some aspects of this machine leave a lot to be desired. The upside to me is the compact size, since I have limited space in my basement workshop. I had a similar issue as the previous poster, with the front edge of the infeed table about 1/16 lower than the back edge, and no way to adjust this. Fortunately the two tables were relatively flat in the longitudinal axis (left-to-right), i.e. just a little bit of a break in alignment across the blades. To fix the back-to-front alignment, I custom machined some small parts to replace the factory-made ones (infeed table spacer, part # JJP8BT-51), and also converted the infeed table from a depth-adjustable one to one that is fixed in depth at about 1/16 , to enable me to adjust the alignment accurately. By design, the infeed table is suspended on two rods that pass between the front and back frame panels and through four infeed table spacers that ride in grooves cut into the frame. These grooves are angled at about 19 degrees downwards and to the right of the machine. Per design, adjusting the depth of cut involves moving the infeed table in or out towards or away from the blades, and in the process sliding the spacers with the rods slightly up or down in their grooves. These infeed table spacers consist of a square side that rides in the grooves, and a concentric cylinder that fits into holes in the infeed table. By machining four replacement parts so that the cylinder part is placed eccentrically with respect to the square part, I was able to lift the infeed table in the front and drop it in the back, resulting in a more level infeed table. Since the two tables were relatively flat in the longitudinal axis, and I had to adjust it only in one plane, I made the two front spacers identical to each other, and the same with the two back ones. Had the alignment been off across the blades in addition, I'd have had to figure out how much to adjust the sideways alignment and make the left spacers different from their right mates. In the process, I machined spacers that fit more snugly than the originals, eliminating some of the loose play of the infeed table in the original design. By also tightening the front nuts on the suspension rods, I fixed the front firmly to the frame, and left the back free to move as in the original. Now, small adjustments of the height adjustment knob rock the back edge of the infeed table slightly in or out and up or down, and allow for very accurate calibration. It took me a few evenings after work to make the replacement spacers, but the materials used were cheap. I used a ¼ x ¾ steel welding bar obtained from a DIY store, a drill press, a handheld rotating metal cutting tool, some files, an electronic depth gauge and an electronic caliper. Assembly requires removing the front and back covers, the drive chain and the two suspension rods with all their little parts (unplug it first!). It may be a little easier to just return the whole thing, but I figured the next one would probably not be that much different.
I have been wanting/needing a unit...
Posted May 16, 2009
I have been wanting/needing a unit like this for several years now and finally picked up my 10" planer/jointer combo unit yesterday. I have yet to use it however! After assembling everything, I found that the infeed table is out-of-square (left to right) across the cutter head. The table slopes down to the left end of the cutter head, taking a shallower cut near the fence. The maunal has a troubleshooting section but there is no information about table alignment anywhere. If I can figure out how to correct this alignment issue, I'm sure I'll get many years of reliable service for my new toy!
