Track Tubes were originally designed to be used with sawhorses, but easily and quickly adapt to the MFT3 and other workbenches to greatly improve your work area. I sold my MFT3 earlier in the year, but was able to borrow an MFT3 from my local Wurth rep., so here's what I came up with. I use low profile "Track Dogs" to hold the table wings in place and the longer dogs make it easy and fast to square up your guide rail or support it at any angle. Quite an improvement!
