"Shop Notes"*
• Inspiration from EEVBlog #493:
• Description of requirements for the design and use
• NOGA base DG0038(?):
Amazon: /
Amazon similar mag but with multiple thread 'cheeseplate': /
KBC Tool:
McMasterCarr (same specs but no brand listed):
• Observance of surface finish on magnetic transfer (grip)
• Moment of inertia and large cross-section members
• Discussion of carbon fiber weave and lay
• Design on camera plate with a 3-bar linkage with detents
• Influence of table vibrations and choice of mounting points
• Build starts @~13m:
• Plate construction
• Chamfering the inside edges on the lathe
• Ball construction
• Architectural steel balls 18ga
Alternatively you can source hollow ball bearings that should have a better roundness tolerance from the get-go. You'll have to contact the bearing house for more info.
Boca Bearings 63mm hollow bearings:
76mm:
Check with your local bearing house.
• Using Stay-Brite to silver-solder the springs

• Creating the radius for seating the tubes to the balls
• Lapping spheres:
Al ring w/bevel, work spun with a cordless drill. Coarse emry paper fitted to ring, then lapping compound
• Using Loctite 243 Blue threadlocker to mount the ring to the base and ball. Everyone that make things with screws should have some blue threadlock.
