Dunno about pollution, Frazer.
I reckon it was coffee grounds............
Finished the re sleeving. All went well........
I decided to house the bearings, inside the flywheels.
Opened out with end mills, in 2mm steps.......
Final pass, with 13mm slot drill, 5.5mm deep.........
Should be a nice shove in fit, probably..........
Sandwiched the cam, between two 5mm thick cast iron discs. Drilled & tapped m3. All held with sleevelock........
Slips in here, nicely. Plugged the grub screw hole, with it's annoying click........
A bit of clearance, here........
And there........
Screwed it all together. First flick, away it went!
And the video. Cos, I know
someone will ask.........
It's now in lots of pieces, for final finishing and assembly.........
Thanks for looking in!
