Hey guys, I just keep coming up with questions. I’m looking at a 6” Delta jointer sometime this week, and would like to know what to check for. I’m mechanically inclined, but I have absolutely no experience operating or maintaining a jointer.

The guy is asking 75 for a older, belt driven floor model. Not sure exactly how old. I figure the belt and knives are both easily replaceable, and I know the table needs to be flat flat flat. Other than that, is there anything that should make me walk away from the deal?

I asked him how heavy it was, and he said he didn’t think it was over 100 pounds. That’s a lot lighter than my research is finding for the weight of a cast iron floor model, but he says it’s been quite some time since he’s done any woodworking, so it may well be he just doesn’t remember how heavy it is.

Update: This is dead, the seller totally misrepresented the jointer.

Critical things are that the fence, infeed, and outfeed tables are flat (not twisted or warped). It’s important that the tables are coplaner. A decent straight edge can confirm. Check the overall condition…severe rust flaking and pitting indicates neglect, but light surface rust is normal and cleans up well.

Less critical – Spin the cutterhead and listen to the bearings…if they grind or are noisy, they’re replaceable. Check the belt, run the motor. If you buy it, you’ll probably want to sharpen the blades.

$75 sounds like a nice deal if it’s in decent condition. Odds are good that it weighs over a 100#.

Good advice above. Hard to go wrong for $75 bucks unless the motor is shot, the bed is very pitted, the tables are not flat, or the mechanisms for fence or tables are broken. Even if it is not coplaner, you can probably shim it using a couple of feeler gauge shims, though it is kind of a pain.

Thanks for the advice scott, and the reinforcements bellow. So I drove a little over 70 miles round trip to find a 4” Delta-Homecraft benchtop model bolted to a ridiculously big base. Walked away from that, with my osb sleds and bungee tie-downs unused.

Only redeeming bit is it was a nice drive, and my happy hatchback only used 2 gallons.
