Materials and Tools
- Do not let the magnets slam together! They are very brittle and will break surprisingly easily if mishandled. They are exceptionally strong and will slam together with enough force to break them.
- Do not use "steel" epoxies as many really do contain steel. They'll flow uncontrollably all over the surface of the magnet, which isn't fun to clean up.
- A non-magnetic tool for pushing the magnets into their pockets (a wooden spoon handle or aluminum x-acto knife handle works nicely).
- Do not let the magnets slam together!
DO NOT ream the hole in the top of the carriages!
|Carriage and End Effector Magnet Installation|
- The magnets come in pairs with pairs being identified as those attracted to each others' same face, that is the sides with the larger diameter recesses should attract each other. Magnets should be placed in the end effector such that nearest-neighbors attract rather than repel. Magnets may be placed in the carriages without regard for polarity.
- Magnets are placed in their pockets with the larger diameter opening facing outward. This is the surface that mates with the ball bearing on the end of a tie rod.
