Well I could build you one but shipping would be prohibitive. Have you considered finding a 'normal' height table with legs that would lend themselves to cutting shorter?

What sort of tools do you have access to? It really isn't that difficult. Often all one needs is a circular saw with a good sharp blade, and put one layer of masking tape on the cutline, both of which will give you a splinter free cut. A 40 tooth blade preferably, at least 24 teeth.
I say one later because more than that can gum up the sawblade and lead to the edge splintering.

A Tablesaw would be better, if ya have access to one.
If you find a suitable table and tell me what tools you have access to, I could be a bit more specific.

Thanks so much for the info, Ron. I did wonder about that, but wasn't sure how to go about it. We've got a good circular saw, a jigsaw, a nail gun and drill. My dad's got a drill press, but nothing else shop-wise.

I'll keep my eyes open for a suitable table, and post back when I've got an update.

Thanks again!

I regularly cut down tables and chairs to a lower height. I find a good pull saw is the tool to use. I can cut all four legs in just a couple of minutes and have it sit perfectly level. I would not begin to try this with a power saw of any type. Too much risk of things going bad much too fast.
