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.

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.

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