Machineshop project (belt sander repair)

[hobby]

　
This is a weekend project job I did for a client, He wanted his very old craftsman heavy duty belt sander repaired, it had an unbearable amount of vibration, and he asked if I could take a look at it, and see what can be done.

Once I showed him the problem, I suggested a repair I could do for it, using my hobby benchtop machineshop tools, and he agreed to it.


Video part 1
is the problem revealed and the solution to fix it, and the start of diisaembling the sander to get to the motor shaft

video part 5
in this video I'm using the shaft fixture we made earlier, to align the fan cage and the bearing flange part on the lathe to temporarily glue in place , then start setting up my rotary table, and aligning the whole fan assembly on the table, getting ready to drill the rivet holes.

video part 6
in this video I have the rivet holes drilled, then I rivet everything together to finish the part into a complete squirrel cage fan, then install it back on the sander and run it to check for any excess vibration.
