I wish I done this sooner!!!
I replaced the straight knives in my old (early 90's model) Jet jointer almost a year ago and I could never get them adjusted correctly. I spent hours at a time trying only to walk away frustrated. I got to the point where I was considering a brand new jointer. While looking at new jointers, I stumbled across these replacement heads and started looking at them. I found this one at Grizzy and I bought this hoping it would for my older Jet jointer/planer. I chose this one because it came with the cutterhead, bearings, bearing caps, pulley, extra cutters, and the tool used to replace/rotate them. All the other cutterheads I looked at were about the same price but were ONLY the cutterhead. I was so excited, I added overnight shipping so I could work on it over the weekend. It was easy to install and it fit perfectly. The instructions to fine tune were not specific to any jointer but were sufficient to outline the process and were easy to follow. The total time to replace and tune my jointer was about 30 - 45 minutes. (That also included the time to clean it all out, lube the moving pieces.) A far cry from the hours/days spent trying to adjust the knives! The results are fantastic!! I ran some test passes on some rough ambrosia maple scrap I had laying around. Maybe 5" wide by 20" long and the passes were smooth and easy. The finished surface was VERY Smooth! So smooth I would say ready for finish.
