Delta jointer gib screw

Joe Grittani

I have a Delta 37-190 6" jointer that I bought used some time ago. I never tried to use it until recently and the results weren't so hot, so I decided to check out the adjustments. It turns out that both the infeed and outfeed tables were sloped to the outfeed end of the machine (straightedge contact at outer end of infeed table and cutterhead end of outfeed table).

I tried to make adjustments per the manual several times but wasn't getting anywhere when I cranked down too hard on the locknut for the infeed gib closest to the cutterhead and twisted it off. I was able to get the gib screw out, with difficulty, without damaging the threads in the casting. Since Delta parts for older machines are non-existent, I'm wondering if anyone has one of these machines they're parting out. All I need is the gib screw and locknut.

Alternately, a friend has a Jet 6" jointer that appears identical to my Delta other than paint color. Does anyone know if parts are interchangeable? Any other options would be gratefully entertained.

Thanks in advance for any advice or help you can offer. I really don't want this to become an expensive boat anchor.

If I remember correctly, the gib screw is just a 1/4-28 setscrew with a cone point. That should be available from a good hardware store, or there are many online sources.The lock nut is a thin 1/4-28 nut, but a standard 1/4-28 nut will work.

Thank you.

You’re right about the size., but the end that seats has a flat on it. I’ve been to Ace Hardware and Home Depot and neither has what I need, 1” 4/24. I don’t know if the corresponding Jet part would work or where else I might find it.

You might try fastenal if you have a local one. Or maybe granger.

What is 1” 4/24? You sure it’s not metric?

What you need to be looking for is refereed to as a dog point screw. A machinist could modify a straight 1/4-28 bolt to one. If you are handy with a Carolina lathe (chuck the bolt in a drill or drill press and use a file to turn the dog point) you could make one yourself.

Try McMaster Carr. They have the best selection of hardware that I have seen anywhere.

Decoding the typos, I think he meant 1/4"-24 tpi UNF.

Bolt Depot is another good source for fasteners.
