Hello, thanks for your replies! I know that you can buy something for cheaper, I just didnt "sell" the versatility/ uses of this device in a work shop. I only listed it as a straight edge type device.
Ill snap some pictures and post a video soon. Yes you can buy (*insert random steel here) cheaper :) But it is all the details in a server rack that has already been done for you that make it a "steal". haha. The amount of pre-tapped holes is rediculous, and each one of those tapped holes can be used for clamping, as a stop for repeated cuts, etc.
For example, 45u = 45*(1u). Any guesses on what 1u = in measurement? :) :) Yup 1.75" / 44.45mm . in a two rail rack system like this, every rail has 6 pre-tapped holes per 1 u, (3 on front of 1u, 3 on back of 1u, per side) so... 270 per side, 540 total. I think the holes are #12/24. FIVE HUNDRED AND FORTY PRE-TAPPED HOLES! haha.
The other great thing is: you can take the base, which is stupid sturdy, and using the 8 pre-drilled holes in the bottom, you can get 3/4" thread x whatever length you want, and turn it in to a portable / versatile and super wide bench clamp as well. And these are just the uses I have come up with so far.
I mean, if you wanted to, you could use them as ski's. who knows?? hahah.
Have a great day all!
