I just acquired a used Delta DJ-20 37-350 model jointer off CL. When trying it out I noticed the cutterhead guard had poor spring action and am now trying to correct that.
I checked a few posts including this one and both there and in the Delta manual it refers to a flat part in the “post” against which you should tighten the set screw. [Note: the Delta parts diagram however appears to refer to this part (#78) as a “support.”]
My problem is that the post/support does not seem to be removeable (not sure it is supposed to be?) and I can’t see or find any flat spot. It will rotate with the set screw removed, but only about 1/4 of a revolution. I have soaked it with WD40 and tried twisting it off with pliers and prying it gently with a screwdriver, but no luck. It still roates only about a 1/4 turn. When I tighten the set screw against it and rotate it, I cannot feel any flat spot. I assume it is the locking of the post in place with the set screw that allows the spring to coil/uncoil during use.
Is the post supposed to be removeable? If you have one, what does the “flat spot” look like and how is it oriented in relation to the post on top?
