Tools & Fabrication - does anybody on here sell lifter tools?

Ive been reading and almost ready to attempt a cam swap. I cant find a jrp lifter tool online and ive heard there a bitch. Does anybody make these that i can purchase or have directions on how to make my own seems simple but some people claim you have to grind one side of one rod?
