Jim Shaper,
Thanks for that, I understand that issue. I have 6 engineered glue-lam beams in my shop that are 8"w x 16"t that span the width of the shop, which is 20'. It was my intention to run a "I" beam down the center, then have a simple trolley to roll the length. Even if I mount a manual chain hoist to it, I am sure it would be a huge help. If I find a electic unit, I may get it. I have an engineer friend that should be able to spec it for me, but the bench comes first! Say, do you use that metal circular saw quite a bit? I have a slow-RPM Milwaukee chop saw... I only used it for 1 job....paid $550 for it, now it's been sitting for 3 years. Is yours a Milwaukee too? Seems that it is pretty handy unit, especially for straight cuts....much better choice than using my plasma...
Just went to the steel yard today for a few items for my current project. Started to get prices for the "C" channel...Getting excited

Say, what size "I" beam did you use again?
Jimmy
