Ok-- here's the scoop! About the mid '90's( don't rightly remember), I bought a Delta 6" Deluxe jointer with an open stand, mobile base, and 4" dust collection. The jointer has a "shute" that's built-in to extract the dust and chips to the d.c. Some of you out there may have this same machine. I hope so, so you might can help.
My problem-this sucker has thrown dust and chips all over the top beds, and the shute clogs up and backs up the chips so bad, the d.c. can't keep up with it. It's done this from the get-go. I called Delta then and relayed the problem(they were in Memphis then). The guy said" You need to replace the foam strip just below the knives, and that'll fix it. Come out to the plant and get a couple". I did. This foam strip had a sticky backing on it, and you had to reach way up in the shoot, take the old one off, and put the new one on. What a P>I>T>A>!!! Being somewhat suspicious, I got out my manual (before I got the strip), and sure enough, it showed that piece of crap on there. Ok- now I'll try it. It held till the water got hot, came off, and went somewhere!!! Three times I tryed this- b.s.!! So-- after all these years, I've put up with chips on the beds, clogged-up shute, and dust and chips all over me!!! That's been years. Now-- I just let the chips fall on the shop floor, and still have to vacumn them up. Another P>I>T>A>. Besides selling this sucker, tell me how to fix it, IF possible. What can I use in place of the so-called " foam strip"? I ain't puttin another one in there!!!
All answers will be weighed heavliy, and questions answered. Come on-I'm waiting. Hurry up-I need to get to making sawdust.

papadan, it is a 2 hp. Delta 1200 cfm. It's about 20-25 ft. from the jointer. There's not a problem with d.c. It works great on all the other machines-it's just the jointer backing up w/ chips and sawdust. Crazy.

I used to have a Delta benchtop 6" and my 2hp grizzly couldn't keep up with it. It works great on my 13" planer and all other tools, just not that jointer. Being so small, I got rid of it anyway, I can use a router and straight edge quicker and have to sweep up anyway. LOL

Well, it's not a benchtop, it's a floor stand model, witha 4" d.c. I'm thinking I might do the same thing-get rid of it and get an 8", or possibly a DJ20. This works works real good, it just that clogging thing that bites!!

Jim: I've cleaned, blowed-out and waxed that thing trying to get the chips to flow to no avail.

Rick, I had a 6" Delta jointer that one day began clogging at the chute as you described with the chips blowing back from the cutters. I would clean out the chute, but it would soon clog again. What I discovered was that I was taking too deep a cut when jointing. I adjusted the depth and it solved my problem. I don't know if this is the case with you, but thought I would pass it along. pkennedy

Thanks Chiefk: No-I don't think that's the problem, because I take very slight cuts. Most times the cuts are around 1/32", and some only about 1/64" I've never took more than 1/16" at a time. I've never even took an 1/8". I've cleaned, waxed, cleaned some more, and it still does it. Mine is a 190 model-older type. But it cuts smooth and accurate, except for the clogging. I just leave the d.c. off now, and sweep up. Thanks for the input.

yarydoc: I'm beginning to think that practically all jointers do this according to feedback.. It just seems to be jointers and not much other tools.. I juat tape a garbage bag under the shute and let'er rip!!!

lcurrent: It's not clogged at a joint or have an obstruction, cause things like the t.s, planer,etc. work fine and good flow seems like. I guess I'll just haver to live with it. But thanks anyway.

If someone else has any ideas, pass them along. We'll do it til "the last dog dies", or the jointer !!!

I occasionaly have ths problem with softer woods like pine or poplar. Does not happen often with oak, cherry or maple. My jointer is set to take 1/32" off per pass. Softwood shavings tend to be long ad stringy while harder woods produce smaller chips. Could also be feed rate related.

FWIW:

I've been watching this, and while I don't know anything about your particular jointer, I've been wondering if the the chute is plastic. If it is, possibly a static charge builds up on it, thereby attracting the chips.

If so, maybe you could fabricate a chute from sheet metal, or coat the plastic with an antistatic spray.

Another thought - if the chute is metal, since it is attached by sticky tape it may be electrically insulated from the rest of the jointer which could allow a static charge to build up on the chute. Solution: Attach a grounding wire between the chute and the jointer frame.

Also check the seal around the edges of the square plastic vac attachment. I have a comparable model and the amount of play in the cover along the bottom edge is fairly high. Since it only has two wing-nut bolts (on either side) to hold it in place there always seems to be a gap on the bottom edge that provides a lesser resistance point where most of your DC suction escapes.

I've found that 2 sided foam tape works well to increase the suction which lessens the above table chips.

Vincent: Doesn't seem to matter what kind of wood you run-they all do it.

Hey Joe: Like I said. it's an older model 190, and it has a metal chute, not plastic. I put a ground wire on it a while back-same results, backflow, clogging, etc. The foam tape is right at the bottom of the cutters, and suppose to eliminate this problem, according to the rep at Delta. These guys couldn't hit the ground with their hats! After about 5-6 calls, I gave up.

Nathan: The plastic cover at the bottom of the chute where the 4" attachment is built-on has a big gap that clogs up bad. It has the two little wingnuts that hold it on. The whole d.c is a piece of crap on this thing.

Rick: That gap is the issue, or at least it was with my 190. I love the beds, cutters, and fence on mine, but the DC has been a lession in frustration.

The passive DC on it is so bad that it regularly clogs the top of the chute. The trick is to make sure the suction from your DC is actively pulling the chips/dust down instead of just clearing out the absurdly small area at the bottom of the chute.

Sounds like an air leak which is what I think NathanAllen is pointing out. The air is not passing over/through the chips. Put Duct tape around the plastic cover and seams of the chute.

If that does not work let the chips fall in a box. Cut a hold in the side of the box and put your DC house in the hole. Should reduce sweeping.

Good luck.

Hey Joe: Who is Papa? Is that you?

Hey Rex: I've tried everything else I know-might as well duct tape it, too !! lol. AAAH-duct tape-America's answer to all your problems, and will fix anything. How do we live without it?
