If Ron is qualified, as you stated he is, and is willing to be and instructor and hopefully develop the instruction materials that would great!
But I've seen people at the Space say "I've been using these for years" ... but really should have said "Hold my beer, watch this."
@nicksilva Let @StanSimmons know Ron Dorst, @richmeyer, @wandrson @John_Marlow and whoever else are authorized user and any others that group may believe are qualified. There is already a AD Directory set up for this tool for authorized users. The same four could be qualified instructors - another AD Directory Stan created.
But until there is at least a syllabus created for instruction and rules as to materials, maximum sizes based on materials, allowable lubricants, etc. then we should hold off using. This is a priority to get done - I'll gladly met with anyone this weekend to help create the materials - just need to know what to put in it. We can immediately have some train the trainer classes and get these going.
Might be wise to start entering classes onto the schedule so classes can begin immediately to show up on the calendar. It would take much for me do a couple Sherline mill classes a couple times a week over the next month.
We would suggest we order some 6061 aluminum bar stock, say 1.000" x 3.0" x 144" ($145 Discount Steel) that can be cut up into 36 small blocks ~ 4" inches long. That would yield 36 pieces and each student could have one, a $5 class fee would get them a piece of material to work with (about $4) and the extra $1 can go towards buying cutters, etc. for the machine.
For the Lathe 6061 1.500" x 144" is $83, these could be cut into 6" lengths at a cost $3.45 for materials, the rest towards tooling. Extra money buys more tooling.
I like the idea of the student getting a piece of practice material (we do this on the Bridgeport (and aluminum block) and lathe (piece of brass) with material I've donated and $5 for a class where most of that is materials seems very reasonable and Aluminum is a very forgiving material to start learning on. The size of the material is large enough to make a small project (or attempt one).
