Hi Kerry,

Amazing way to do this mod!!!

As always I have a few questions, I hope you don’t mind.

I see that you wrote that the Lightbridge bearing is 0.155" thick, and the aluminium disc with circle laminated to it is 0.107” thick. But how thick is the aluminum setting circle disk itself?

What grade of aluminum did you use for the setting circle?

What size of thumb screw did you find worked well with the metal tab (bent over the edge of the bottom base melamine) thickness, to stop striping of the threads?

Do you find that there is any side to side wobble of the top and bottom melamine bases to be a problem with binding?

Any problems with the aluminum setting circle damaging or grooving the base melamine, or binding on the Lightbridge bearing?

You must be a NASA engineer or something; your mods are truly professional and inspiring. Thanks for taking the time to share them with all of us.
