Leveling a billiard table to an exact horizontal orientation requires a very accurate "spirit level" device (also called "bubble level"). In this video I show the complete process, from requirements and design, to prototype manufacturing of the bubble level from 2 borosilicate glass disks. If you need more details on how to make a spherical surface, you might want to check out this previous video: https://www.youtube.com/watch?v=-E058yElkFM The two video's referred to below show the optical contact bonding process in detail, so make sure you check them out. It is quite impressive to see 2 surfaces melt together spontaneously by just atomic forces at the surface: https://www.youtube.com/watch?v=se3K_MWR488 https://www.youtube.com/watch?v=xZTdurPlhXE The link below refers to a Sydor video on their Optipro Glassmaster 520 angular machine: https://www.youtube.com/watch?v=oT2_55QNWUs "Fabrication Methods for Precision Optics" by Hank H. Karow contains detailed information on how to build and operate an angular machine, for those of you interested in building one.
