So, I'm repairing an NCR (By Estes) Lance Beta, to get back to flight status. First, the NC base was cracked up pretty good, so I cut off the bottom and wedge, and epoxied a piece of 3" BT, sliced to make it a bit smaller. To make the shoulder smooth, a piece of thin-wall BT80 was cut to fit the wedge. Lastly, a 1/4" plywood bulkhead was expoxied, with sufficient weight to make it stable up to a 4 grain H. The small hole is where I'll put my RF tracker.
