The paint finish looks very nice! How did you do it? Maybe I'm just too impatient to produce a good paint job -- I always end up with runs and sags in mine.

Beautiful!!

What's the sensitivity of the bubble?

I also want to build same. Are you willing to post the list of materials?

Thank you.

How did you manage the verticality of the minim prism pole? How did you calibrate the agreement between the plate bubble and the mini prism pole axis?

Looking good!!!

Looked at attempting something similar myself but didn't have the metalwork skills so purchased something off the bay which works for me
