I actually love this plan and I think I’m going to try it when I get off work in the morning. With a heavy mouseball. That extra weight could cause some damage but could feel so great. Awesome plan! Thanks!
I’m not sure what’s in the heavier mouse balls. Might be lead or has lead in it. If so, you’d definately want to put some sort of plastic tube in there and expoxy it in place to make it safer. Also, the “skin” might have a tendency to tear once pierced, over time, which can be avoided with the tube having a flanged lip glued over the openings to hold things together.
I think there is this place that makes delrin or celcon balls. I should check that old link and see about ordering some.
