Mirror Making Class?


Recommended Posts

I am thinking about starting a telescope mirror making class in Stockton-on-Tees, in the north east of England. If anyone is interested in attending such a class please get in touch with me. I can provide mirror blanks etc if required. At this stage the whole thing is just an idea, if I can get enough interested parties I will finalise details. I do not have a start date in mind; again this is dependent on the level of interest.

PM me your email address if you are interested.

John,

I'm a secondary school teacher in Scotland (Physics) and I run an astronomy club. Our club is fairly active and this year we aim to complete our build of a 12 inch dobsonian. We've already made the mirror cell and upper OTA, just the mirror box, rocker and of course, the mirror itself to go. After much thought we have decided to grind our own mirror - we are all new to mirror grinding but what we lack in experience we will make up with enthusiasm.

I followed (lurked) and was greatly impressed by your previous thread on mirror grinding and was certainly planning to make reference to the guidance there as we go along. Again, distance would preclude our direct involvement but if you are able to make anything from your classes available say on-line (videos, tutorials, blogs etc) it would be greatly appreciated. I know this would place an extra burden on you but the knowledge and experience you have is invaluable.

Yes, I think a tutorial on making mirrors would be very good. And if you could include some info on the turntable, such as the rotation speed, that would be very useful too. Links to sources of materials would also be handy. This is something I'd quite like to have a go at sometime.

I second this. I'd even pay for the online lessons.

For those that want a turntable what I did was use my drill press and 2 pulleys. One was a 1" and the other was 8". I could set the RPM by the belts on the drill press it work good for me. Instructables is holding a contest for space related how-to guides. I put one up on there you might want to check out even vote for if you like it =). Like all the instructables on the site its not a complete guide but a good overview that can fill in the gaps where you might get stuck or give ideas on what route to take.

Glasspusher - most people here can send images, post KE readings etc., is it not possible to do a distance learning thing with this ? I've made a few mirrors but would like to do a 12-inch.

Just a thought

Francis, I am more than willing to help any aspiring mirror makers either through this forum or via personal email. I do have the aim of producing a tutorial video sometime in the future. The mirror making class did get off the ground, started with 5 students, ended up with 2, both are progressing well and enjoying the process.
