Excessively Holey I/H beam clamping jig

Excessively that is over the original one shown in the Wood Magazine flyer they sent me recently. I was able to find it online here:

https://www.woodmagazine.com/woodworkin ... -convert-2

I like the idea but needed to make a few changes of course. First this is only a paper design at this point and I have just finished it in sketchup so I might well make a few changes before it is all done. Anyway I wanted to use 20mm holes and 32mm spacing thus providing ways to attach to the 96mm spaced holes on my MFT.

I'm still evaluating all the holes but one could just do the ones you want and eliminate a few. Like wise for the length, width and height.

I have a pair of the non-holey jigs like this and have found them quite useful and these might be even more useful for the MFT.

Not sure when I will get out to the shop to make these, still way to cold for me to work very long out there but I'd like to finish the design and be ready when it does warm up. This and a stack of other projects are all waiting.

So any suggestions or comments?

What are you using your current one for?

I use them for a lot of things but a few examples are in the older post:

The ones in the old post kind of remind me of the torsion boxes that Mike Farrington puts on top of his sawhorses. It could be worth a look at how he uses his to see if you can think of any other design additions for your new clamp beams. Just a thought...

Ed, I just reported pronosoft who repeated one of your posts. He did that to me the other day but I let it go. Now I think it might be some kind of a robot.
