It was not until I started building the top that I discovered a bit of a sticking point with the FWW article. The vise hardware used in that article actually will BARELY fit based on the dimensions in the article, but you would have to make some sort of modification somewhere along the line to get it done. In order to get it to work, you have to do basically one of the following:

1. Leave all the dimensions as-is. This would leave just enough room for all the hardware to fit, but you would NOT be able to make the front vise 18″ wide as stated in the article — you would have to make it about 14″ wide. No big deal, but I wanted a wider vise jaw.
2. Cut off the screws of the twin screw vise about a couple inches. This would work, but I ain’t doing that!
3. Drill holes in the right trestle top to clear the twin screws. Again, this would work…. but with a standard twin screw spacing, you would end up drilling very near or even right through the mortises!
4. Carve out the left trestle top. Alternatively, you could carve or rout out a big rabbet in the left side of the trestle top to clear the front vise hardware (or combine some limited carving with one of the above solutions).
5. Make the trestle base shorter. This is a good option, but it requires that you know ahead of time that the dimensions in the article won’t work. I didn’t.
6. Make the top longer. When I rough cut out my pieces for the top lamination, I cut each piece just a bit longer “just in case”. Turns out it’s a good thing I did…. this extra length was almost enough to fix the issue for me.

No big deal, really, but it was sort of annoying that the dimensions given in the article won’t work as published. The only reason I realized that this would be an issue is because I spent time playing around with the design in CAD. Anyone who does this, or draws up their own plans or full-size drawings, would catch the problem too. The problem is, if you DIDN’T do full-size drawings or CAD, and you trusted the dimensions in the article, you would be stuck with one of the first 4 solutions above (or having to use different hardware).
