Hello peoples, I’m in the need of some serious help. Where can I post a question that will get me the most exposure. I really need some advice about this Jointer. It seems that noone really wants to respond with the correct information. Dont take this the wrong way I do appreciate the comments that I’ve gotten thus far. but none of them are definitive enough for me to make a decision on what to do here. I’m sorry, and If I need to wait a few more years to get more experience under my belt before I join a site like this one then thats what I will do. I can assure you one thing though. If I see a question that I know something about, ” which probably will not be much” Ha Ha then I will be the first to try and help. I read a comment a little while back and It talked about people bickering back and fourth instead of helping one another just over someone speaking there mind. come on guy’s were grown adults here. Think about this. With all the crapt we get from buying products thats made in other countrys thats not worth diddly and then the dealers that dont want to stand behind what they sell isn’t that enough hardship to deal with. This is the problem. People in our own country are enabling this way of doing business. Let us be the one to stop it dead in the tracks and help one another with pride in what we say and do. Our hard earned money is leaving this country and we sit around and do nothing. NOW I said what was on my mind and I feel better atleast for a minute anyway uh. Somebody out there out of all these people have to have a Delta DJ30 12” jointer and would know what I’m talking about. This is a prime example of what i was saying. The people at Delta cant even answer this question about these knives being too long. There 12 1/4 “s long . and there isn’t enough room between the pillow blocks to allow for this. The blades stick out into the rabbit groove by 1/4”. I know that certainly they would’nt send you new knives that you have to grind down just to install them. Where can I post this question that will get the most exposure. Thanks alot. Christopher http://i1218.photobucket.com/albums/dd401/flatboarder/100_0659.jpg!

I do not own a DJ30 but will attempt to help. Are these direct replacement knives from Delta or after market? If from Delta I am wondering if there is a possibility of the knives being missed in quality control. If after market where did you purchase the knives?

Nor do I have a DJ30, but I would check the cost of a new set against the cost to take then to a machine shop to be ground to size. If you decide to grind them yourself, DO NOT over heat the ends. If you do you will screw up the heat treat and possibly warp them. All depending on how hot you allow them to get. Those can’t be a cheap replacement.
Just my two cents worth. Rand

The correct answer to my question was they overhang a 1/4” on this jointer for people that want to bevel the ends there is plenty there put the knives on and shut up. Ha ha that would be great in that perfect world. In the world of me my next question is who knows a simple method to install these rascals. Man there kicking my butt. the center always want to stay low @ 3 thou. I made the jig that the DELTA”S owners manual has in it. It’s kicking my butt also. This woodwoorking business is hard work sometimes. Hopefully I will get my Jointer working tommorow. Thanks for all the advise I really do appreciate them!!! yiaaak uhhhhh yeah all of them

Just a theory as I don’t know anything about your particular jointer but, does the DJ30 mean that the knife length should be 300mm?

ok I gotcha Yeah I have button tips for my dial ind. I have the one way plus another smaller shop fox mag. kind. I made a jig out of a piece of 3/4 birch plywood it’s 10” wide with two ears 1 1/2 wide by 3” s long one on each end. The problem I’m having is when I pust down on the board to put the knives down I’ll get the sides close but the center of knife goes too far down , the only way I know how to get it back up is to release the screws. This machine has the springs onderneath the knives. christopher

I like the dial indicator with the button, but I don’t have one. I did purchase one of these from Woodcraft to set my knives. I have an older, 1928 Crescent 8”, jointer and it works fine. I can change knives in about 30 minutes with this jig.

Oh I see I do remember seeing those tips before on some video. The knives were straight yes. This machine doesn’t have adjuster screws but it does have the springs. Esta Knife retrofit where do you find that. Yes I agree about the porchop cutter guards. I guess I would be looking for a job If I had worked for you that would have been short lived ha ha. I’m disabled anyhow so I’m safe from getting fired. Woodworking started out as a hobby four years ago and now its my life. I dont have a computer at my shop so If anyone wishes to give me some advise on how to set these knives they will have to call me @ 850-712-3876 I do appreciate very much any and all help I can get. This trade can be extremely trying at times for a newbe. Are you saying to take the springs out? Christopher

Yeah your right I’m sorry about that I got the knives in as per the owners manual and It didn’t work so well. I got the knives within .002 of each other. When I made a cut It felt like it was banging on the bottom of the board. I think I need to raise the knives up to .030 above the locking bar ” GIB’ and then set the outfeed table according to that. The manual says to set the out feed table .015 above the cutterhead body so this it what I did. I’m using a OneWay Multi gauge with the flat tip. after I finnished setting everything up I then dropped the outfeed table .003 below the top of the knifes arc. Is this correct so far?

What I did was I set the outfeed table .015 above the cutter head as per the owners manual, I then set the knives even with outfeed table after that I dropped the outfeed table a few thou .003 and then ran a test cut. and It was terrible tear out, ripples If felt as if the knives were beating off the wood instead of cutting it. When the machine came in it was set up differently than the manual. The out feed table was set at .035 above the cutthead and the knives were set within .001 even with the outfeed table the cut was ok and smoothe but the knives were coming apart at the lamination also whoever had put those knives on had cross threades the gib screws so I wanted to change them. This is when I looked in the manual for the directions on setting the knives and noticed that the outfeed table was suppose to be at .015 above the cutter head body. I’m not sure what to do I reset everything last night to the .030 and It cut better but It still isn;t right. I’m about ready to sell all this equipment buy a harley and go on a sabatical.

Just a figure of speach there about the harley. These Knives were dead on when I set them even with the outfeed table. I not using the cutter head as a refrence to set the knives I’m sorry as if sounded that way the outfeed table is set at .015 above the cutter head body so when the knives are set even with the table there at .015 above the cutter head body as well right. something wasn’t right cause I could feel it in my hands. How tight do these gib screws need to be I’m wondering if that could have been the problem. I hate problems like this there so small but yet so big

To each his own. I no longer use gauges or jigs for jointer knives. A true 1×2 x12” piece of soft pine works great. Adjust the knives so they just catch the wood. Do this on each end and the center. Yes, you do need to develop a bit of a feel for this, but once you get it this particular job goes from frustrating sweaty hours of playing with feeler gauges or jigs to about twenty minutes of relaxed calm work. By the way, is the Delta outfeed table flat across the 12” width? If it dips, then that might explain some of problems your encountering.
