« Part 4: Finally some color Part 5 of Walker Turner restoration series Part 6: Starting to go back together!! »

As part of the COMPLETE restoration of the nice Walker Tuner table saw I have been working on I ran into a little problem with the arbor bearings.

I have completely disassembled the saw and have it painted and now its finally time to start putting it back together. I wanted to replace the old arbor bearings with new, sealed ones. The old bearings were open and had to be greased and I want to take that out of the equation.

I measured the shaft and the arbor itself and asked a few questions of the guys at and came up a suitable replacement, or so I thought. I ordered the bearings for $12 ea and they arrived a few days later. As it came time to install them I found that they slid easily on the arbor shaft, however too easily. The bearing would not seat snugly on the shaft at all, the bore of the bearing actually spins on the shaft. So it was back to OWWM and seems that others have had the same problem.

I was thinking the solution would be to take the shaft to a machine shop and have the bearing surface of the shaft knurled to raise the metal and snug the bearing up. While at the shop we put a micrometer to the shaft and it kinda surprised me to find out the shaft is metric! Hard to fathom on an American Made piece of equipment from WWII era. The shaft is 19mm, the bearings I ordered are 3/4”. There is only .002” difference from 19mm to 3/4, but enough the bearings spin freely. The machinist said he could knurl it for me but would take about a month before he would have time to get to it. He’s a little busy. We looked for a replacement bearing with an ID of 19mm but to no avail. 19mm is an odd size, I am guessing but I figure the manufacturer did that on purpose.

So I am now stuck with 2 bearings that are too loose on the shaft to be of any benefit. Kinda like a sock on a rooster, it will fit but not very useful. I had to think of another option. I could have a new shaft machined to fit the modern bearings, I could reuse the old bearings, which is not very appealing to me or I could look for another option. I chose option 3.

Option 3 was to use loctite. I went to my local NAPA store and found Loctite sleeve retainer. The retainer is used in the auto industry to install cylinder sleeves, valve guides etc. Loctite states it will bond an fill gaps up to .005”. BINGO!! With a difference of only .002 I am well within the tolerance. I cleaned the shaft and bearing with acetone, appled the loctite and slid the bearing home. After letting the loctite cure for the recommeded 24 hours I went to a local auto repair shop, a buddy of mine, and used their press and pressed the shaft with 1 bearing installed into the trunnion. It slid in without a hitch! I then used the loctite on the 2nd bearing and pressed it in as well. I was very thankful that the cast iron trunnion didn’t crack, after all it is 60+ years old.

Just went through your whole blog series over your saw. Very nice, I love old tools that have been restored. I can not wait to see the final saw and what you build with it.

The only OWWM machines I’ve ever restored that weren’t metric where Craftsman badged. Bearings where international long before it was popular to be a global company so there was basically a standard set.

There are some special bores like the 3/4 you used, but for the most part they’re all metric, even from the 30’s

OWWM is a great resource for info. Some of the people there are helpful and know their stuff. But I ran into one there that was a total jerk. He was very rude and hateful. So I don’t go there anymore. I stick to this site and a few others. This site so far for me has been great. I like to have a couple of site to pop in through the day for a couple of minutes when I have to wait. I find tools to restore and use for myself. I have found out if I think about what my issue I am having with a project I can usually figure out the answer. It sounds like you did just that with this project.

Willy…......I think there are people at every site that can come off as a jerk. I can think of a few here!! In my opinion OWWM IS the resource. I think you should try the site again. With the amount of knowledge and info that is available there why would you let one person turn you away?

OWWM is a great resource for info there is no doubt about that. But without going into the details I gave info on a question and stressed safety. I get a nasty email and was told by someone they would be happy if I left, I think they felt unconfortable with the subject. . Its one thing for a lone wolf to insult someone but when its one of the main ones I felt it was best if I left. I will not be a contributor to a website if I feel like I have to walk on eggshells all the time so as not to offend someone. And by all means if you need info check them out,I wish the site the best. But as for me I was insulted by the person and will not post anymore. I really don’t need the site but I just I enjoyed going there just to take a break. It makes you leary of any site when you run into a person like that. I don’t post on sites much because of people like that.

Have your say...
