I found ridgid plastic material that I can increase the height of the foot of the table. It is black and it is really hard material, so this is why I am trying to remove the rubber foot.
Thanks for your explanation. I'm only 5' 8" so I don't need to increase the working height of my MFT for my back to be comfortable. Best wishes for a successful customization!
I replaced the rubber feet on my CS70 a few months ago ( link )
Mine were worn, so I just cut the sides with a utility knife to get them off, but then I had trouble getting the replacements on. I don't think there was adhesive on the original feet, you just have to heat the rubber to make it more flexible and they will slide off easily. (I didn't have a heatgun at hand, so I let them soak in hot water which worked very well)
