i need help!

[cosworth34677]

ok im about done with turn tables. i hate trying to make them and make something fit! and when i do it work for a while the boom breaks or skips!!

anyway i need something that will fit around this slew ring and use the setup i got here. maybe fit around the the one bruder i made? im going to put a metal frame in excavator when i go on vacation, but for now i just need a easy fix. try not to show me anything that will cost lost of money as i am on a budget and can't spend hundreds of dollars on stuff. as always thanks for the help
