- 3/8" steel release pin for use on a large trebuchet
- Designed to accurately calibrate repeat launches
- Easy to install, easy to adjust
- Custom designed by Oakland Ballistics
DetailsHow to use the release pin: You will need to attach the pivot hole to your throwing arm. The hole is ½” wide. Next you will need to attach a turnbuckle to the push/pull hole, again the hole is ½”. This will allow for very small, precise adjustments. You will then attach the other end of the turnbuckle and you are done. We have used this to launch 8 lb projectiles 900 ft. We cannot guarantee the breaking point of this but it is laser cut out of 3/8” steel.
