Thanks to our large group of volunteer instructors, we can hold these mirror class and give everyone the individualized attention they require. Several of our instructors work professionally in the optics industry, and many have competed dozens or mirrors and more complicated optics as amateurs.

Officers, Trustees and Full Members of the club have had to successfully make a mirror or other quality optical surface.

Final Report

Students: This year saw us have 11 new students and 7 returning students start out the year with us. First couple of classes everyone was very enthusiastic but we saw a large drop off around Christmas with only 11 total students pushing thru to the end of the season.  A couple students had some setbacks, scratches during figuring and such, and one damaged his mirror beyond repair. We had only three completions, one of the returning students and two from this year’s class. Several are “soooo” close to being done and will either return to us next year to finish or find another means such as Dave Kelly house.

Instructors: I would like to thank those instructors who helped out and showed up nearly all the time and always offered to help out. There seems to have been a big drop in member participation this year, we need to improve on this in order to keep the class going, we cannot depend on four or so members only to provide a good learning experience, especially during the first couple of classes.

Equipment: The barrels Jay and Dick made up have withstood the beating and multiple moves to date and only need some cleaning and maybe a fresh coat of paint to keep them going for a couple more years. We need to develop an improved travel testing system as I intend to put the tunnel into the bunk house; Rick Hunter has expressed interest in helping me do so.

Facilities: Mirror Lab #1 in the Pavilion is working out to be a great space for rough grinding. Though a little tight with eleven people starting at the same time, hopefully we’ll have a warm fall and can start some outside next class. McGregor for polishing and figuring has raised some concerns about the library not being an appropriate space for such tasks, I agree. John M and I have put a plan in place to renovate the bunk house into a better space for fine grinding and finishing mirrors, and will end up being the permanent home for the test tunnel after this year’s convention. Fletcher House as always is a godsend for us during the long winter days when our home is closed in with snow and they should be thanked for offering the facilities and the storage space.

Future: Hopefully next class will see us with a better space in the Bunk House and many finished mirrors that have carried over the last two years and those that started with the new class. For the 2013-2014 class I would also like to see us get some new potential members and instructors.
