HI Rene,


I'd concur. If it's really necessary later, we used to mount vibration sensitive hardness testing equipment in industry (steel mill) next to a processing line that vibrated the whole floor noticeably, by simply sitting the machine onto a bit of plywood which floated on a 'sheet' of 8 x 6 = 48 tennis balls trapped in an appropriately sized plywood frame.

Worked perfectly and removed 99+% of serious vibration as a simple damper.


This would be a simple addition to the slab later if vibration is an issue.


The issue with the under-concrete mounting is that if there's any dirt, the swelling of wet soil might cause an issue with slab cracking or out-of-level.



(I bought that Meade LX90 off you a while ago, but new streetlight plus neighbours floodlights plus a 40kg pup have completely stopped any observations.)


Regards,
