Topic tags/keywords: delta jointer

I have a Delta DJ-20 8” American made (90s era) Jointer.

Alright, so here is what happened. I was pushing a medium sized log over my jointer, when the table height adjustment knob came loose, and the table dropped. It was so dynamic that it crashed the replaceable aluminum in-feed lip into the blade. The log wasn’t all that heavy, but I was pushing pretty good on it.

So, I inspected the jointer after the crash, and found that the aluminum lip was chewed up pretty good, and two of the casted brackets that hold the bar linkages together had sheared through. I ordered some part from an outfit online and they arrived 8 weeks later from china after having to call them a few times to check up on the order… Apparently Delta doesn’t support with spare parts for their old machines anymore. In fact the parts that I got back are power coated green, and I’m willing to bet that they are Grizzly clone parts.

Long story short, I went out to start fixing things today, and my heart dropped when I flipped the jointer table over and discovered that the infeed table has a crack on each side of the table

that have propagated up from the bottom gusset to the table surface. It is one of those times when you just sit there speechless for a few moments.

Wow, that must have made one hell of a noise… Maybe someday you can find a donor machine to get an infeed table from? I would guess it wouldn’t be particularly economical to try to order a replacement

Bad luck. I feel for you. Although…... It does justify ( even in your own mind) a new toy, I mean Jointer.

Has anyone heard of this happening?

I figured out that Grizzly G0490 is an almost identical clone to the DJ-20, and a few others out there. They sell the indeed table for around $220. I can’t wait to hear how much shipping will be. I’d like to find a salvage unit that I can buy locally..

I’m considering buying a new machine.

That was a wow moment I am sure. Upgrade or fix, hard to say which way to go.

One thing you and other have mentioned is Delta no longer supplying parts for older machines. Heck of a way to instill confidence that when current generation of machines need parts they won’t do the same thing.

Doesn’t seem like a good design that would allow the table to fall like that. I can leave my infeed table unlocked it might move do the vibration but it would never just fall like that.

Well, if your looking for design problems, check out that notch they put in the casting with an internal chamfer. Thats called a stress riser. It focuses all of the load at that small point where you see the crack. There is one just like it on the other side of the table.

Clearly you need a heavier built machine. My first jointer threw a knife and bent the out feed and infeed table,opened the knife slot like a can of tuna fish.
Don’t even try to fix it lots of great deals on heavy built jointers.

Sorry about the damage.

Is it normal to run a log on a jointer?

One suggestion you might try…if there is a welding shop you know of that has a TIG machine…..they make a special {expensive} TIG rod for welding cast iron/cast steel with a TIG welder . We used to call it “99” because it is 99% pure nickle. It is expensive, but the rods are 3 foot long and it is sold by the pound. It wasn’t good for welding big intricate castings like cylinder heads or engine blocks, but for small to medium sized machine castings it worked pretty good. Talk to the welder, if he has used it and is comfortable with it then I would sure give it a try. He might have to order the rod and might want some money up front because not every welding shop or supplier keeps it on the shelf because of the price. It’s not crazy high, but when you consider a pound of aluminum rod or chrome moly steel, the whole bundle cost less than one nickle rod {$20-$40}.
It works better if you pre-heat the parts first and put them back in an oven afterwards to cool slowly. Once done it is as strong or better than the casting before it broke. Used to use it all the time when I ran a machine shop. Many welders don’t use it or even know it exist. Not sure if they are still in business, but an outfit called “Palco” used to make an excellent cast rod for use with a DC shielded metal arc welder. It was expensive too, but again, not crazy.

Wow… that’s a catastrophic failure. You might be able to have it clamped back into shape welded, but welding cast iron is tricky and you’ll need to find someone who’s good at it.

Sorry that happened to you. Must have scared the heck out of you.
Delta has been through several ownership changes so that might explain why they are not carrying old parts anymore.
I’m agree with others. Time for a new Jointer. There is some pretty good iron out there these days and Christmas is very soon.

If that had happened to me, I would probably be looking to get some clean underwear !!!! Good luck on getting it fixed.
