Alright, I don't know how ambitious this is, but maybe there are enough of us that could work together and get something rolling.
I have a welder and a plasma cutter at my disposal, and I have a good amount of sheetmetal around (I would have a bunch more but one of my customers scrapped out a bunch

), along with experience drilling and tapping metal.
My thought is if there are a cople of people around that we could get the materials together and over the course of a saturday or sunday weld up a few slider rails for some libbies.
Either we can work off a blueprint, and everyone can bring their own metal stock, or we can delegate different material purchases to make the project go smoother.
I can probably get the steel pretty easily from my old job at the sheetmetal fab shop, but I figured that it might be a good excuse for a NE ohio LOST meet.
If anyone has better ideas, let me know, here are some pictures of some of my gear:
(well sort-of, my welder is the red one in the foreground, and my plasma is the smaller red thing in the foreground, the picture was a sheetmetal guard I installed in chi-town)
I wish that the miller in the background was mine...
Anyway, my thought is that this coulud go really well if we can bring cut to size parts to the table, and just weld them together... I am good with AUTO CAD and can host prints for peer review.
