I want to integrate two MTF/3 table into a work bench. I'd like to be able to adjust the two MFT's to be co-planer. I already have the connector bars. Looking at the tables, there doesn't seem to be anyway to bolt them down. I would have thought and number of MFT owners would have tried this in the past, but a web search doesn't bring up anything. My current thought is to drill a hole through the center of the rubber feet and bolt it down. Has anyone done this before?
