Not many places stock/sell 1/8 inch aluminum rod. It is too fragile for typical
warehouse handling and there is not much call. But you can find
aluminum filler rod (TIG welding) in 1/8 fairly easily. Unfortunately it
typically comes in too short of lengths (36 inches) to make some of the
longer elements at 2M.
Not to mention that 1/8 inch rod is really too fragile for a 2M antenna. Even 3/16 inch is very marginal. But if you insist on 1/8 inch aluminum rod you CAN get it from Ryerson. Here is the link to the rod page. They have warehouses all over the country--but whether they will have it in stock is another issue.
Stainless steel keepers are also very hard to find in small quantities other than from antenna manufacturers who buy a lot of them. A distributor will have a minimum order that may be intimidating. The last time I bought some I ended up buying 1000 ea of the 1/4 inch and 1000 ea of the 3/16 inch ones. And they still didn't really appreciate my little order all that much.
The following distributor can get them for you. I don't recall the minimum order or the prices but I know that if I wanted a relatively small quantity that I would buy them from Mike Stahl at M-squared, although I don't think he has 1/8 inch ones.
Prospect fastener doesn't make them easy to find but you can click on the Rotor Clip icon: or on this url http://www.prospectfastener.com/tapered_section_rings.htm
Then click on TX: http://www.prospectfastener.com/tx-ty.htm
You'll probably want the TY version--in your case TY-12 SS--because of the slight "coning" of the fingers that helps to get it started.
Other manufacturers besides Rotor Clip include Waldes, I.R.R, and Anderton. But SS versions of these are hard to find at local hardware stores!!!! ;-) As you no doubt have discovered.
This should be enough to get you started, but with minimums etc you are not going to get off all that cheaply.
