I received my Gen 4 irons with SW of C9. I would like to change to D1 at least. I understand the weight port screw can be removed but it in there with red loctite. I tried briefly to remove it by applying about 30 seconds of the small butane torch flame directly on it. I stopped because I was not sure if that is the right way and I just have to heat it longer to melt the loctite.
If there is any other way to do it with lesser effort would appreciate any feedback.
Thank you in advance!
excellent idea regarding the solder gun sloppytypist.
