When making bandsaw wheels there are three basic things to keep in mind; wobble, run-out and lastly wheel balancing.
Mounting the bearing flanges on the upper wheel.
Pressed in the bearings and pre drilled the flanges.
Got some hardware stuff from ALDI this morning including a couple of castor sets @ $10 each, Bunnings price would be like 3 times that.
Some of the stuff I need to use larger 10mm ID bearings.
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!
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.
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.
