Re: diy spherometer
If you can manage with the current f5.5, you can go straight to polishing. This will save you a lot of time, having to glue glass facets to the tool then grind them in to match the surface then remove the facets afterwards prior to polishing.
How important is that extra 1/2 stop?
Will be following this project with interest.
Good luck
