I'm on the lookout for a used jointer since my old 6" Craftsman just broke down. I've been using it on my furniture side hustle, and now it looks like I need to upgrade sooner than planned. I found a Delta DJ-20 from 1988 for $500, but I'm a bit anxious about its condition and history since it came from a school auction. It shows some light rust and needs new knives, but I'm curious if it's wise to take a chance on it. I'm weighing this against the cost of a new jointer at over $2200. Considering issues like replacement parts availability, durability, and overall reliability, how does the older DJ-20 stack up?

I've owned a 1990 DJ-15 and can say it was a fantastic machine. The DJ-20 is likely an even better choice! Delta's older jointers, especially the cast iron parts, are great and tend to perform as well or better than modern models. Just make sure to check the fence and tables for flatness. If you test those and the cutter head runs true, then you're probably looking at a good deal! That listing sounds promising, and I'd grab it if I were closer!
Good to know! Any specific tips for checking flatness? I'm planning to bring a flat edge and feeler gauges. What level of flatness is considered acceptable?
