spool

I wiped up some disks on Sketchup and then cut them out on CNC mill.

I glued them together using craft glue.

I used an 1/8th inch shaft dremel bit as a guide.

The steppers have a 1/8th” shaft (with a flat). So I figured if I made 1/8″ hole in the spool I could put them on with loctite.

I can’t figure out another way than to “glue” the spool onto the shaft.

It seems like a good idea to have the spool directly on the shaft of the stepper assembly as well.

I made the spool diameter 1″ and the walls 2″. That makes the circumference 3.141565″ or so.

I used 8 disks to make each spool.

One concern I have is that the steppers seem to get quite warm. I guess I need to make sure I have the right loctite. I have three kids. Silly company numbers their products rather than describes the differences. I suppose if I google the numbers I can figure out which one to use.
