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 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.
