20 Most Recent Delta Jointer Blades 6 Inch Fits , Jet Jointers Questions & Answers

Lower the in feed table to keep it clear of your work, hold a straight edge on the out feed table, both sides, adj the knives to just touch the straight edge, both sides the same, all knives set the same, should work like a charm, do not answer the phone while you are doing this. check all jib screws twice to make sure they are tight. Hope this helps.

go to Dewaltservicenet.com and with your model number you can download a schematic for this tool and also order the parts online. I tried finding them but there are too many jointers listed in the Delta category.

Go to partsdirect.com and type in your model number. From there, you can order whatever you need for your jointer.

You have to loosen the nuts behind the knife blocks before those allen screws will be able to raise or lower the height. They are only meant as a fine adjustment for dialing in the height. (So the tip of the knife at the highest arc of the cutterhead revolution is in line with the height of the outfeed table, as measured, for example, with a steel straightedge or rule.)
You'll need a small open end wrench to loosen the nuts on one knife only, then replace and adjust the heights, then retighten, then move to the next knife, etc. As you retighten, be careful not to tweak the knife out of alignement, and tighten back and forth across the cutterhead, rather than in a straight line from one side to the other, so the torque is spread evenly across the cutterhead...
Here's a link to a parts guide and owner's manual if that would help you out...If you don't find one there check here and maybe there's something close enough to guide you through the process....
Be careful...If those knives aren't properly tightened you'll destroy the beds, and make sure you unplug the power to the machine before working on it.

go to Dewaltservicenet.com and under the service locator on the right hand side type in your information. The blade set number that I came up with is 37-658 and they show that as qty 3 in one package.

Table may have disengaged from the threads---apply pressure on the table to reengage as you try to lower it

I can send you an exact copy of your model. We repair this type of equipment so if you need parts, please let me know.

I can't get a hit on that number, the model must be other. But it shouldn't be too hard.
Try to find a reliable sharpening service in your area; someone who does saw blades and knives for the cabinet shops will have a source for tool steel and carbide and can make you a set of knives for your jointer. Just get tool steel. While it won't hold it's edge quite as long as carbide knives, it will take a sharper edge to begin with, and should last just fine if you don't run sand through it.
If you have the original knives, hang onto them as they most likely can be resharpened to like new condition, and steel today ain't necessarily what it used to be.
The critical factor is the height. It's usually between 5/8" and 3/4" tall. You want them to be able to rest all the way down on the adjustable pistons without sticking up more than 10-15 thousands above the cutterhead. That will give you the most resharpenings from a set. You might want to invest in a magnaset to help with setting the knives in place.
Here's a link to the sharpening service I use: http://maps.google.com/maps?rls=com.microsoft:en-us&oe=UTF-8&um=1&ie=UTF-8&q=Precision+sharpening+%2B+Albuquerque,+NM&fb=1&split=1&gl=us&view=text&latlng=15322695688682105671
Finally, I would almost bet some contemporary delta replacement knives would work. If you find a place that will return your funds if they don't, you might be able to order them online. These guys will carry them if you can't find someone nearer you: http://woodworker.com

Go to the bottom of the page of this link, under "Product Details", the manual is a PDF:

http://www.amazon.com/708457K-JJ-6CSX-Horsepower-Jointer-230-Volt/dp/B00006ANS5

I called Jet and they e-mailed me a pdf file with the older manual. There is a toll free number on their website.

Check on www.owwm.com. You will probably find your machine on their and resources to help you in your quest. It's a great site for old tool hounds.

Go to the Dewalt service website at http://servicenet.dewalt.com and do a search for your model number in the Find Parts box. Use 37-190 (with the dash) or you'll get a long list of parts. The Type 1 and Type 2 don't list a manual but the Type 3 does. The differences in Types are usually very minor, look that one up and see if it fits your needs for your jointer.

You are looking at a major disassembly to get at the cutter head bearings, everything is built around the cutter head. The motor drives the cutter head on one end of it and the cutter head drives the rollers at the other end. Most of the components have to be removed to get the cutter head and it's bearings out. You can go to www.ereplacementparts.com and do a search on your model number for a good breakdown of your planner and see what you need to remove to get at the cutter head and it's bearings.

You might have the outfeed table lower than the blade. If the outfeed table is adjustable, then you can check it easily with a steel ruler. With the Power OFF, lay the steel rule on edge on the outfeed table so that it hangs over the blade. Rotate the blade by hand in the forward direction. The blade just just barely touch the ruler. If the ruler is bumped up and pulled forward by the blade, then this is the problem. If your outfeed table is not adjustable, then you need to adjust your blades. If this is not the problem it may be that your wood is not uniformly dried.

The most important part of the jointer is that the cutting edge is perfectly level with the out feed table, then, bring up the infeed table, with straight edge on rear, make all adj necessary to get these things lined up flat, not level, but flat, straight, even. Then it will cut perfectly flat and even. no snipes,. Hope this helps.

It might seem obvious, and no doubt you've long since resolved this question, but was it possibly a breaker that threw due to an amperage overload on the circuit the jointer was plugged into?
The online manual (available here) takes pains to make sure the receptacle the jointer's plugged into is well grounded and any extension cords are of sufficient guage.
Assuming all that's in order, I guess you could bypass the switch to check to see if it is in fact at fault. Replacement parts are available from the same link above.

Check to see if your blades are set to the same depth as per your manual. Also you should only be taking off 1/32" at a time for a true cut.

In case you haven't found it, try this...

I'm going to guess that this unit runs on 240V. I would first suspect that you lost one leg and only have 110V going to this unit.

Check that and update this with the model if not the case.

Thanks,
Dan

I assume you want to know how to get it adjusted just right, not how to move the outfeed table up and down. The easiest way I have found is to lay a metal ruler on edge on the outfeed table so that it extends over the blades. Slowly turn the blade forward by hand while you lower the outfeed table. Do that until the blade snags the metal ruler. Then raise the table until the blades just stop snagging the straight-edge.
