Careful with the salt lens.

This project is awesome. I'm not understanding how the glass fits and how exactly the bending is positioned and why. Newbie.....

You are doing a terrific job! I'm great at glassblowing, electronics etc but my mechanical/plumbing skills are horrible. Me too! I really want to hear how it performs. When I was getting my degree one of my friends built a traditional one as part of his Master's degree and it produced about 8-10 Watts. When I did undergrad chem research before going to physics I did a lot of IR specs and we'd use cylindrical salt xtals. While trying to learn new things while I was working well after school one of the things I studied was laser th'y. The author of one book made a nearly field improvised CO2 laser and his output coupler and mirror were creative genius! Old glasses with the right dioptres. He used the toothpase soln, dam and steel rod trick to make a small hole in one lens then coated them with gold under vacuum (I'm sure we all still can visit our old depts and ask to use the vac deposition stuff ).

This is excellent! I like the use of the salt. Never would have thought of that. I can't wait to see how this thing performs! Keep up the good work man!
