I recently acquired a used Powermatic 8" PJ882 parallelogram jointer. The machine is in fine shape and I got it for a very attractive price.
I am seriously considering putting a Byrd head in it. I would also put new bearings in it while I am at it although the old ones seem fine. Yes, the head is expensive but the cost is not an issue. The jointer will likely remain in my family for many years.
Any insights on doing this job would be appreciated.
