Topic tags/keywords: parallelogram dj 15 jointer table adjustments delta jointer

These seem to be popular jointers. Mine is 1987 model 37 150. Is there some one who has gone through the table alignment procedures. I am having a real nightmare with this. After pulling the top set screws over the concentric adjusters I apparently backed out the first set screws too far and now the adjusters are pushing in as I try to turn them with a special tool I made for the job. Tech support at Delta told me (too late) that there is a groove in the concentric adjustment rings that the set screw goes into which holds it in place. I didn’t see that on any instructions. The in feed table rocks, it lifts up at the cutter end, I don’t know what to do about that The fence mount hits the out feed so I had to raise it which I don’t like because now its not seated on the castings. I’m not inept with machinery but these adjustment methods seem entirely too difficult. There seems to be no starting point.
Any help would be appreciated. Thanks

Just a thought. I once owned a DJ 20. I believe I remember that there was a section in the owners manual about how to adjust the the tables to be parallel to one another. I purchased this machine new around 2002, to the best of my knowledge. It may be a starting point. Good Luck

I am about to embark on adjusting my parallelogram Delta DJ15 37150 circa 1987 tables as well and would welcome any first hand insight into the process. To make matters worse on my end it seems like someone tried using a screwdriver and ruined the brass fitting around the eccentric bushing. Most the set screws seem to be stripped as well. I don’t fully understand how they work nor what options I may have to fix, adjust, replace etc….

BCO given it was over a year ago perhaps you have an update to your feed?

Here’s a picture of what I’m looking at…

Please Help.

I’m sure this forum can help you with the process of adjusting the tables.
But first you should get those cams fixed or at least usable.
And while your at it start looking for a straight edge.And a level is not good enough.
