I am concerned there might be a better way to put the cast iron wheels back on my 20" bandsaw than what we did - basically hit them on with a hammer, they were unbelievably tight.
I'm restoring a Davis & Wells 20" bandsaw, very very slowly.
I took the wheels off with a pulley with no issues, many months back.
Today I had some time, and so did my machinist buddy, so we decided it was time to put the new bearings on the shafts and re-mount the wheels.
I let him lead the work, it's his area of expertise, though he doesn't work on woodworking machines.
It was tough to get the wheels to go on the shafts. I rubbed a little oil on the shaft and on the wheel, and they went on about 1/8" and then stopped. My buddy picked up a dead blow hammer and tapped the center of the wheel. Nothing. He upped the strength of his blows until he was really beating on those wheels (we braced the other end of the shaft with a 2x4 and clamps to stop it from being pushed through), and I mean really beating. It took a while to get each wheel on.
There was no rust or any visible impediment on the shaft or the hub.
I've googled this and all I find is advice on how to install tires.
Is there a better way?
My buddy pointed out some obvious signs of the wheel hubs having been hit with a smooth hammer in the past, so this wasn't the first time for this poor bandsaw.
I figure I'm going to have to spend some time balancing these wheels.
