A great catalog to order raw material and tools is McMaster-Carr Supply Co. P.O. Box 54960 Los Angeles, Calif. 90054-0960. They have the best catalog I have seen and are very helpful in finding supplies.

If you’re trying to make brass bridges for your Telecaster I would suggest using a “Free Cutting Brass”. It’s great for drilling and tapping. For making the vintage type rollers use a 5/16 inch rod. For the steel 1/4-inch rollers use the 1010 cold drawn steel. For Jazz and Precision Bass you can use 5/16 inch 1010 cold drawn too.
