I'm a hobbyist cue maker and have never had a jump break cue, so don't destroy me for not knowing. I have a house cue that the points run high enough to make a j/b out of, so I was just wondering what the specs should be? Mostly where the two joints are to be put in and how much is the jump sectoin suppose to weigh. Is there any special taper for the shaft or anything else I should know before cutting? If you can help that would be great, thanks.
