Hahaha - I just built a unit with 32 bolts all cut to length by hand. It really didn't take very long and was a whole lot easier than getting out all the heavy equipment... You've got nuts no the back side you can use as a cutting guide, no? That is what really makes it easy. But you do need a good blade. I used a 24 tooth bi-metal Lenox blade. And I have a really good hack saw. If you've got a cheapy hacksaw - go find a power tool... Not that Dremel though - that will be far more work than a good hacksaw.Well, the obvious answer is "just try using what you've got", which I'll probably do. If it were 2 or 3 bolts, I'd do the hacksaw thing, or use the bench grinder. We're talking 4 screws per wood strip times maybe 14 strips, and I'm less enthusiastic about doing that the slow manual way...
