Have made some new pulleys with 608 bearings for my Corexy system.
Those are machined? Cool! Looks like aluminum.
I modified the openbuilds pulley design for 624 and 623 bearings, the 624 size I could print on FDM, the 623 I had done on an SLA.
@raykholo Made the pulleys in my lathe from a 30mm bolt 6082-T6 aluminum.
@Jan_erik_Halvorsen what kind of lathe do you have 
@Alex_Krause Chester Model B.
Looks like a handy tool to own 
Are these pulleys made Form Aluminium?
@Sebastian_Schmidt 6082-T6 aluminum
its missing the central flange
@Tiago_Vale Do not see the point when the pulley is heated and shrinked onto the bearings.
