Hi everyone, I just got the rhinehart x50 today. I read the entire book but I can not find out how to put the pygmy tip on it. I have nigerians. It also has a switch that has a position for S or for D which position should the switch be in and what are they for? Also when you disbud is it better to pull the top of and re-burn for a second or should you just burn until you see the copper ring and leave it be? I have heard of doing it both ways, which one is better? Thanks everyone going to disbud today if I can figure out how to get the tip on lol..
