hey whats up all i haven't been around much. on my latest bike i got i put BMX pegs on the frame and welded some brasses onto the frame well the bmx pegs are about 1/4 inch to short and the gas tank hits the ground first. what are those pucks or whatever made of i need something along the lines of what a hockey pucks made of? i know someone that can machine them but where can i get 2 blocks 2 inch's around and 5 inch's long? i have looks at every hardware store and have came up with nothing

 

the plastic is called delrin and i get mine online in 24" long pieces. hook it up in a lathe and mill away
