OK guys, no pictures to share, but then there isn’t much to see as these are covered by a metal hub.

We have a little metal cart that goes behind our yard tractor and about once a year we have to replace the OEM tires at $10/ea. The new tires come with wheels and bearings, but the bearing are really cheap and wear out within a couple of months. A pair of bearings is about $11 and wears out just as quickly, even if I pack them every couple of weeks.

I got tired of this so I decided to make some wooden bearings with the thought that they couldn’t be much worse than the metal ones, the problem was, the OEM wheels had a cone shaped hub so only the end of each bearing would contact the hub and the axle at the same time.

Enter Harbor Freight:

I bought 2 13X4 2 ply knobby dolly wheels rated at 300 Lbs each. These had bearings for a 5/8” axles but mine was a 3/4” axle so I decided to take a page from the old wagon builders and use wooden bearings.

I grabbed a scrap of white oak and using a 3/4” Forstner bit, made a hole about 1/2” deep then removed that bit and used a 1 1/2” hole saw that centered on the pilot hole the Forstner bit made.
I cut the round out, (the 1 1/2” hole saw cuts a 1 3/8” ID plug), then finished the center hole with the Forstner bit.
They are a bit loose, but the tractor never moves or 7MPH so no problem. I’ve regreased the bearings 2 times this year and hauled close to 50,000 pounds of green oak trees cut up in chunks that I can lift.

I miked the bearings each time and have found no wear yet.

I did have to replace one of the bearings due to driving it off the axle and I had accidentally cut it on a knot.

All in all, I am a happy camper with this and it has saved our employer a couple hundred dollars, besides it makes my little wood shop more valuable to him!

If you want pictures, I can take some but there isn’t much to see.

Jolly good show old chap. Always nice to redesign something that works better than store bought I say. And I have no idea why I’m typing as an English gentleman. I’m just feeling it.

Somewhere in my 77 years, I came across wooden bearings for gristmill machines made from lignum vitae wood.
It is supposed to be self lubricating.

Bois D’arc (bodock here in the South) will work too.

Harryn, I have never run into Lignum Vitae but I would like to.

Bill, I use ‘Bodark’ (here in Texas), for a lot of stuff. I only have a cheap Dewalt Bimetal hole saw and a Porter Cable Forstner bit set.

It takes nearly 4” of bearing to cover each side and my HF drill press doesn’t go any slower than 660 rpm. I would hate to wear them out with high speed heat.
