So it's been a while and I've been off thinking more than playing. About a month ago I got a break in the cold (yes, I still haven't hung my heater) so I wondered out and started working on my workspace plan. A little background - I only have a 3 car garage and I need more surface space when working on a variety of projects. One thing I miss not having (in regards to the business years ago) is assembly and fabrication tables. I had more than a few and many of them were fairly big (4x4 w/ 3/4-inch thick tops and a few a little longer). I needed something a little lighter and more mobile. Something that could be moved to where i need it when I need it and then put away when I'm done.
The months I spend in the garage usually result in restless moments filled with research and thinking. At some point I ran across this guy Ron Paulk who came up with this really cool twist on a torsion box assembly table that's specifically designed to be a mobile work bench. Ron calls it "The Ultimate Workbench" and justifiably so.
The surface uses a grip of thru-holes that are used for a variety of purposes (like clamping, filtering, etc) which I found to be an incredibly interesting idea. Woodworkers have used these in thick assembly tables for years to accept bench dogs which were also used for fixturing and work holding but recently a company named Festool came out with a system they call the MFT (Multi-Function Table) which incorporates many perfectly (CNC) spaced holes similar to Ron's design (which is the chicken/egg I have no idea).
If I had a shop big enough to support it, I'd certainly build one like Ron's plans make (4' x 8') but I just don't have that much usable floor especially when I have a car in the garage so I decided I want to build 2 (or maybe 3) of these in a variety of sizes so I can use them when I need them where I need them. As with any of my projects, the project I set forth to do isn't the only resulting project so I decided to document what I've done thus far.
The first table is a 4 foot long by 30-inch wide table. I wanted a smaller one that I could take inside or use in conjunction with a larger table for smaller fabrication jobs.
The top is constructed using 1/2-inch ply for the surface (and the bottom once I attach it) and 3/4-inch sides and bracing to add a little more strength.
It's much lighter than I thought it was going to be and it will be easy (even once the bottom is installed, to move it around. the surface as a mess of 3/4-inch holes drilled 4-inches on center for fixturing. Festool actually makes clamps that are specifically designed for clamping through the holes.
I've always used the edge of a table or counter top to clamp to and I've never found a better solution until I was able to use this setup for the first time. It makes assembly of just about anything extremely easy and is only limited by the size of the clamps you have. As you can imagine I'm not all that happy that not a single clamp I already have fits through a 3/4-inch hole.
