For years, I have been using a variety of aids for painting and holding model rockets during assembly. Finally, I realized I could do a little laser-cut plywood jig that would make things much easier.
The NCR Handy Stand helps you during the assembly and painting of model rockets. This set includs supports for use with two 18mm and two 13mm motor mounts. It can easily be adapted for 24mm motor mounts (adapter not included). If you need extra heft, you can clamp it to your workbench for added stability.
