I am very pleased with my new jointer now that I've cleaned up the surface rust on the tables and gotten the outfeed set correctly. It's a Jet JJ-6CSX that I got at an auction for about $240 with buyers premium and tax, and it even has a new set of spare knives included. I know a 6" jointer is not considered worthwhile by many here, but 98% of the time it's all I want. I'm glad to have the longer tables and movable outfeed, those are big steps up from my old '70s Rockwell.
My question is about a little pin type of thing on the back of the infeed table. It was fitted into a hole and prevented the table moving beyond a quite small range. I wanted it set up for about a 1/32" cut depth for flattening banjo necks, and until I removed this pin I couldn't get the table that high. I have not seen this type of thing on any of the other older jointers I've had, and I'm wondering if there is some reason why it is needed that I don't know about. I have taken it out as shown in the picture and it doesn't seem to have affected anything. I am guessing it may be to prevent someone from moving the infeed table in far enough to interfere with the knives, but if that was it I would think it should have some more range of movement than it does. I'll be grateful for any advice.
