Greetings,
I recieved many interesting replies on this. The best results in
pouring lead into larger diameter tubes come from filling the entire
tube prior to cutting it into the smaller lengths.
Oh well! Since I had already cut the tube up, I opted for the
simplest fix and used a urethane glue to hold the lead into the
sections. The end was then easy to machine clean.
Now I have 40oz of ballast and a wing joiner 20oz heavier than the
carbon one which should be enough.
Thanks all for your input.
