Previously I had asked about advice on changing the knives on this jointer. I got some good tips, but still haven't gotten the knives out. They are pretty well stuck, and I really don't think they have ever been changed. That led me to wonder how old this dude is. I am guessing it at around 50 years but have not been able to find a serial number anywhere. I thought maybe someone could give me a rough estimate based on a picture. At this point I am thinking about replacing the entire cutterhead and bearings and anything else I get into that doesn't look to good. This jointer was owned most of its life by a lumberyard that recently went out of business. I bought it from a guy who got it from the lumberyard. Evidently he just cleaned and painted it and sold it to me for $100. I don't think it has ever had any real maintenance. It really doesn't matter much how old it is, I'm just curious. Thanks!
I concur with Loren rockwell/delta 37-220 BTW you can find the cutter head on ebay. One just sold with knives for $80. Shelix also still makes a head for this jointer if you want to go all the way bot $385
Jason - Your 37-220 was made between 1964-65 and 1972. Prior to 64-65 the base they used was the deco style base (not sure exactly which year they changed). Starting in 1973 the logo was changed to the Rockwell "peace sign" logo. If you find the serial number it can be narrowed down to the exact year it was made.
Holbs- The bolts holding the knives in the cutter head will not turn for nothing. I haven't tried to get the cutter head out yet.
tefinn- I did not know what model it was, it doesn't seem to have a tag on it anywhere. I'm hoping the 220 part isn't about voltage because it had a 110 plug on it when I bought it and thats what I've been running it on.
That is a good looking machine, I've always liked and end mounted fence on a jointer. I'm sure you've already use a penetrating oil on the bolts so I won't suggest that but have you tried using an impact drill driver on it. That might do the job, they work wonders on seized up lug nuts.
Good looking machine. Even if you have to buy a new head I thing you did good for $100. Lol
If you can pull the head and can't get the screws out perhaps a machine shop and bore them out and retap the holes. At that point upgrading to the $400 head that was mentioned above might be comparable
