8” Bandsaw – Replacing lower wheel bearings

Having completed the upper wheel, we now need to dismantled some stuff around the bottom of the saw to gain access and remove the lower wheel.

When I removed the lower wheel I noticed the bearings, like the upper lot...were completely stuffed.

8” Bandsaw – Bearing flanges continued

When making bandsaw wheels there are three basic things to keep in mind; wobble, run-out and lastly wheel balancing.

Continuing on from the last session I bored four holes (each side of the flange) to allow for  quick clamps to be passed through to clamp the flanges to the wheel - for wobble alignment.

Mounting the bearing flanges on the upper wheel.

Pressed in the bearings and pre drilled the flanges.

ALDI Shopping - Castors

Got some hardware stuff from ALDI this morning including a couple of castor sets @ $10 each, Bunnings price would be like 3 times that.

8” Bandsaw – Bought more hardware

Some of the stuff I need to use larger 10mm ID bearings.

Including M10 nuts and lock nuts…and M10 rod and threaded rod.

8” Bandsaw – Tyres for the wheels

Dropped into my local tyre place in Scoresby and asked the guy there if he had any used inner tubes. I was lucky as they are not used so much these days, he came back from the bin with a truck inner tube from a job the day before...and it's a perfect fit!

With much haste cut out a section...will it fit?

8” Bandsaw – Larger wheel bearings

The 608 skateboard wheel bearings are breaking down, the MDF wheels are pretty small and light so I suspect the bearing can't handle the blade tension forces. We need larger bearings and...mount them in flanges glued and screwed on either side of each wheel.

You can see the debris at the bottom of the wheel shaft slot from the ruptured front bearing.
