I prefer rivets over chicago screws, they're simpler, and less likely to cause problems further on down the road.

Blacksb21, the binding posts kind of look like a rivet. You have a flat head screw and the other part is a threaded tube with a flat head. You can go to McMaster.com and search on binding posts. They have 1/8" in stainless steel, zinc coated steel, aluminum, etc., I have been getting all my supplies from them and they have great service. I see Bent has used the binding posts in stainless steel but now uses rivets because of supply issues. I used the zinc coated steel posts which I hope hold up to the task. I also used Blue Locktite which I also hope holds. I wanted to be able to take them apart if need be for any modifications being this is my first changer. I am starting to see some issues with clearance on the bottom end of the changer fingers and may have to remake 2 or 3 fingers. When I drilled the holes for the pull rods I got a little wide and you just don't have any room to spare. Part of the learning curve I guess. I just saw where Burt prefers rivets also, probably the way to go. I believe they mean actual rivets and not pop rivets or blind rivets and requires a special tool for installation? Thanks again for the input.

What about something like the "Flush-on-both-Sides" countersunk rivets or the "Tamper resistant two piece" rivets?

Steve, I don't know what others use but I used 16 gauge steel which is 0.058" I believe in thickness. Also, the site you reference having make your parts did not come up for me? Is that the complete name? I'll be posting pics in a couple of days at most of my changer, just a couple of little things left to finish. Next up are the endplates :o

Hello dgalloway, the site is e-machine.com you will need to down load the free program a couple of times before you can draw your designs, you then can see it in three D, then you can place your order and they will give you a quote or cost that day you need to give your name and address for them to ship to you, takes anywhere from a week to two weeks for delivery unless you use expidite from UPS, they except Visa master card and American express but sometimes they can cost a little more but worth it.
