Ball screws
Bought a small section of ball screw with the associated nut, nut housing, and end block
SFU1605 300mm - 16mm diameter and 5mm pitch
Trying to work out linear forces and the RPM range if it were to be driven from a stepper motor or servo
Mechanical engineering is tough
CNC work
Cut the first actual project on the CNC
Movable cradle for holding chassis - makes working on them super easy
Had to spend some serious time working on getting the machine to cut 90 degree
Iterative process
Flex in the machine - 0.02” accuracy
Going to cut some speaker cabs next
Added a simple fan radiator
8020 catalog arrives sometime soon….
ARP 2600 repair
A client found a unit that was put in a closet in 1984
It was only pulled out last weekend and is now in my hands to do some repairs
