On my Basa 1 I managed to have the back of the blade cut into the rear guide/thrust bearing (whatever it's called). It wore a groove and snapped my blade. Not 100% sure what was going wrong but it didn't seem to want to rotate properly when the blade touched it.
So instead I bought a small sealed bearing and took a piece of 10mm bar and drilled a hole off centre. So my rear bearing is now a proper bearing. I can rotate it to move it left or right a little as it's off centre. Seems to be working ok now.
I did intend on re-designing the entire holder to have 3 proper bearing running with the outer edges touching the blade rather than the sides of the bearing, which has never made sense to me.
