Greetings!
Wanted to save some $ and made my own ant-vibration pads.  These work great on my LX200 8" SCT.  Parts were from Walmart or amazon.  The anti-vib pads are heavy duty (for HVAC use): DiversiTech MP2-E E.V.A. Anti-Vibration Pad, 2" x 2" x 7/8".  A Pack of 4 was ~$7 shipped. Furniture leg coaster was added to keep the tripod leg from slipping off the pad.  Used a small screw to attach to pad.
 
Parts:
Vib 1
 
Assembled:
Vib 2
 
Final product with mount:
Vib 3

Would be nice if you could tell us whether or not they work. With and without pads in place. Is there a difference? If so how much?

I've been using square pads with cork centers for years but I never found it necessary to use the additional furniture cups.  The rubber surface provides ample friction to prevent slipping, even with the bare aluminum swivel feet on my Eagle Pier.

Yes, they make a difference.  Available on Amazon:

Thanks for the comment Harry!

They seem to damp vibration on my gravel observing site but not sure how to quantitate.  I'm exploring test using a "vibrometer" app on my phone just to answer the challenge.  At issue is determining and appropriate metric - time it takes to dampen the vibration or the absolute magnitude of vibration.  Looking at how this changes with both focus and moving the scope in dec.

 

Appreciate any thought/suggestions you/others may have 

Best

In forty five years of observing I have never used vibration pads with any of my telescopes in particular my vintage Celestron C8. I am not sure that I need them. In my experience with a Tasco refractor the vibration was bad but that was a inexpensive mount. That problem went away when I bought the C8. I do have vibration with my Stellarvue SV110ED since the tube tends to oscillate when focus is adjusted, but I think that is a different issue. The main thing is when you focus, does that cause the scope to vibrate and how long does it take for it to settle down to a steady image.
