Kyle; there is all kinds of 1/4 pins available. Do you have a Hobby store or Lowes near you? They most likely have 1/4 brass rod at hand or stainless, though I recommend nickel silver pins just cause I like them LOL. If not them, every knife maker supply I know of has 1/4 pins, screws and Loveless bolts. There are 5/16 corby's for sale as well to fill in the 1/4 holes with the screw. Here is just one example amongst many.

There are many more. PM me if you need more references as there are at least two dozen that clog my poor old mind at the moment. Use USPS shippers if you can as UPS is more expensive. Just FYI.
I could add welder suppliers, but they sell by the pound usually, but bronze rod is different than brass so it's worth a call to call and ask as they have many different rods for sale.
