Static Rocket Fire Test rig

*Disclaimer: Use this design at your own risk. Rockets and compressed gas are dangerous and should only be used by adults that know what they are doing and children under supervision of adults that know what they are doing. Check the laws for model rocketry in your country before launching anything. Never stand in front of or behind a rocket and always keep a fire extinguisher on hand.

I am doing a project to observe the effects of drag on rockets and I needed some baseline data. That's where the static fire testing rig comes in. This rig is designed to test thrust without the effects of gravity or drag. The idea is to mount the motor(or compressed gas) horizontally on a nearly frictionless rail system.

For this project, you will need:
* 1 - Push forcemeter, I used a Nextech DSF-200, any of their DSF forcemeters should fit
* 2 - 8mm polished linear rods, I used a set of 300mm long rods
* 4 - LMUU bearings, I used drylin polymer bearings because caused the least amount of fric
