A review of the Jet JJ-6HHDX Long Bed Jointer. This is a 6 inch jointer that comes with a helical cutter head. Helical cutter heads offer many advantages over the traditional jointer's 3 knife setup.
Extremely helpful, thank you! I just upgraded from a benchtop jointer to an 8" Jet (with helical head) I found very reasonably priced at a surplus store. Although I am not new to using a jointer, moving from a tiny 6" benchtop to this beast is a whole new ballgame! You are a great teacher and I also subscribed before the video was even 1/2 way through. Looking forward to viewing more videos from you in the future!
Thanks for the kind words. I was a school teacher for 40 years. in that time I hopefully learned a few things about breaking things down into smaller elements and explaining them to others.
*Just as I expected I have nothing bad to say about this jointer **MyBest.Tools** make a solid clean and level cut and adjusts in increments of 1/8ths and 1/4s I ran stock 2"x4" x8" at 12' long and had no issue.*
Thanks for the video. I'm getting ready to purchase this same jointer just not gonna spring for the helical version just yet. Any tips on installing the power twist belt? Maybe it's pretty straight forward.
Best tip I can give is to use a needle nose plier in order to add or remove segments to the belt. Way too hard to do with bare hands. Really worth the cost and effort to upgrade.
Thank you. I was having removing the blades on my Delta 6" and have started shopping for a new one. Just can't get the bolts to budge. Called Delta up and they want me to remove cutter head before they can help.
+Fred Davis Is this the first time you tried to remove the knives from the Delta. If so be aware that the bolts turn in the opposite direction than is normal. You can get a close-up view of this in another video on my channel entitled "How To Set Up a Jointer". If you are considering replacing it with a helical head jointer you will never be disappointed. My only regret is that I did not do it sooner. Good Luck!
Hello Dave, thanks for the video. Question for you, have you checked face-jointed boards against a straight edge? I have the same jointer and I've tried and tried and tried over several months and many adjustments I can never get a board to be 100% flat over an entire face. I usually end up with board with a bow with a 1 or 2 thousands of an inch dip in the middle for example along a 36" long board.
Interesting. I have never noticed that problem. My guess would be it is a problem with feeding the board. Do you use push blocks? the middle of the board is where it is most likely to exhibit flex and if you exert downward pressure there while feeding the cut this could be the cause of your problem. Next time I am using the jointer I will do some tests.
Belt is from Harbor Freight. A lot of their stuff is pretty bad but their segmented belt is a great value and equal in quality to anything else out there. I use it on many of my tools for years without issues. www.harborfreight.com/vibration-free-link-belt-43771.html
Dave hello, I'm from Mexico, and here we have only one Jet store in all the country, I'm gonna buy the 6" JJ-6SDCX and the Jointer came with the regular 3 knives head. My question is: is the same Jointer that the one you have only with diferente cutting heads?And other question is: later I can buy the Helical Cuttinghead to my jointer and how much cost only the helical head? Thanks for your response. Your video was very helpful to make my mind about which jointer buy.
The JJ-6CSDX and the JJ-6HHDX appear to be the same Jointer with 2 differences. First one is obviously the Helical cutter head. The second difference is the JJ-6CSDX has the on/off buttons mounted on the base while the JJ-6HHDX has them mounted on a paddle above the bed of the jointer. I don't know if Jet sells the helical head as a replacement part but even if they did I'm sure the cost would be more than if you purchased the JJ-6HHDX in the first place. You can buy Byrd or Grizzly Helical heads but they will cost around $400. Hope this helps.
Hi Dave! Do you still have this jointer? Are you still happy with it? Have the beds sagged any? Are you still happy with the 6 inch size. You have a new sub by the way! Thanks.
Still have it. Still very happy with it. Beds are as straight as the day I got it. Still very content with the 6 inch size, I don't make large projects very often and this jointer fulfills my needs.
Enjoyed your video for the first time. looking at others. But I do have a couple of questions about the helical knives. In order to rotate a knife does the screw have to come completely out or can you just loosen and turn? Secondly. where does the screw fall if you drop it in the machine? Will it create a problem and hurt the machine in any way?
I just did a test to confirm. Yes, you can loosen the screw and rotate the carbide insert without completely removing the screw. But ..... this may not be the best approach. If you have any dust particles that get under the insert in will not lay flat and cause ridges. I usually completely remove the insert and clean both it and the cutterhead with a firm brush before re-installing. Ans yes it appears to be relatively easy to retrieve a dropped screw.
Hi Dave! Great Video! Liked & Subbed! Quick question: Do you know of a source that I can retrofit my existing Delta™ 6" jointer, with a helical cutter head srtup? Thanks in Advance!..... Gus
Because you are dealing with the axis of the cutting from the cutterhead and a different axis direction to the center line of rotation of the cutter block; you need that radiused 4 edge of each cutter knife just to do a flat plane. Any knife will cut smoothly giving the cut we need, but, overcoming the different axises angle is done by the knife radius and this is the mathmatics and physics of it. When we have a Tersa knife in operation and are about to mill some questionable wood; the Tersa shines as quickly inserting some old knives comes into play. This is my reason for going with Tersa. Chrome metal Tersa knives are worthless, whereas, M42 or carbide is the horse to ride in the race.
It depends on the make and model of your jointer. Companies such as Byrd Shelix make carbide insert cutter heads for a variety of jointers. Go on their website and see if they make one for your jointer.It is a pricey upgrade but worth every penny.
The problem I see with those quiet helical cutterheads is that you can Not drown out your wife's "command" requests when she comes to the door and wants you to stop your doing and go get something for her. So tis best to keep atleast one noisy machine going most of the time. Just a thought. thanks for the review
@@daveswoodshop782 I have the 7.5hp Oneida twin filter cyclone sitting outside the shop with a 10" intake and 10" return port. Funny world: when I installed the return (rather than heat Chicago in the winter) I had so much vac pressure on the door to the house (bathroom) I could not grip the door knob and open the door. I thought the wife was on the other side and jokingly she was foot-at-the-door trying to keep me in the shop. I said begging loudly, "honey, let me in; I've got to go!!!" But, she would not budge! So I gave it my all and the door began to open!! She was not there after I broke the vacuum. At 3400 cu/ft per min I had created a monster; almost a wet-Monster. The Oneida gage says 2.2" of vacuum. So stay away from those larger cyclones.
