<cut>... the MFTC has a standard workbench height of 900mm, same as an MFT so i would avoid making it much taller!
Hmmm, I don't know about this 'standard bench height' comment.
Yes, 900 mm is an ideal working height for people of a specific height- but that ain't me... You see, I'm 6' 2" tall and as a working height 900 mm (roughly 35 3/8") is just plain uncomfortable. At 900 mm I find I am in a constant stoop and develop a back ache or strain over an extended period of time. I decided long ago I would not stoop to work, if I didn't have to. Everyone has their own ideal work height; a work height that is comfortable to work at for an extended period of time without undue strain. And it is a very personal choice.
For me I have settled on 1050 mm as my standard bench height.
This is both for the workshop and on site.
Every bench, infeed and outfeed table, etc in my workshop is at 1050 mm. This uniformity of height has greatly improved my workflows and at this height I can work comfortably for much longer and do not 'tire' for an extended period of time.
I have a love/hate relationship with my MFT. I love the concept, and really love the design elements- being the top itself and T rail extrusions and of course the interaction of clamps, etc... but for me the table is too flimsy to be at true workbench, it is too small to handle sheetgoods, it is too low to be comfortable to work at for an extended period... So I have taken the design elements and incorporated them into all my other (self-built) work surfaces.
And indeed, that is what Timtool has done with this magnificent bench.
It is a cracker of an idea- but I just wanted to say if you are going to build your own workbench- of any type- you should build the bench to your preferred work height....
Not the other way round and try an conform your work practices to a 'standard' height that may not be ideal for you...
Sorry, I got a bit long winded getting to my point....
