8” Bandsaw – Larger bearings / relocate motor

Not happy the way the saw is running, there’s to much wheel wobble – why ???

Removed the blade to check the wheels and was shocked to find they are just flopping around, something drastic has happened to the bearings.

For V1.1 we will use the larger 6200 2RS (12/32) bearings, two per wheel mounted in flange blocks.

The motor will be moved closer to the front (reduce footprint) so the V-belt will directly drive a Vee pulley fixed to the back of the lower wheel.

Meanwhile made a hinged blade cover for the left and also added the third thrust bearing to the guide assembly.

BTW: Grabbed another ALDI LED lamp reduced to $10 from $15, last one so don't make fun about my colour choice.

8” Bandsaw – Motor mount assembly

As posted pulled out the nice brushless motor from the Simpson washing machine and yesterday spent some time thinking about how make the motor mount assembly.

The motor needs to adjust in all four directions, front to back for pulley adjustment and left to right for belt tension.

The motor runs at 1400rpm, perfect for this type of application and has ample power.

8” Bandsaw 14 – Video of running saw

Doing some test cutting on the saw which is powered by a Simpson washing machine motor.

8” Bandsaw 13 – Test cutting video

Finally doing some test cutting, the filming abruptly ended but is was simply the drill chuck coming loose on the drive shaft. I think we need a better solution to drive the saw.

The bench setup and ready to turn on 240V power.

8” Bandsaw 11 – Testing the motor

Working out how to wire up and bench test the Simpson washing machine motor.

A very nice brushless 3-wire capacitor start motor on the left and the wiring loom on the right - how do we wire it up ???

8” Bandsaw 9 – Bench grinder

We need something better than a electric drill to drive the saw, what about a bench grinder.

Took off one of the wheels and was preparing to make a pulley for the grinder shaft to drive the saw with a Vee belt when I thought of the Simpson washing machine in the back of the van.
