OK, it’s time to get back to the Turbochopper!!! I have really been able to make some serious progress on this project in a short amount of time. I am just about ready to put the bike on it’s wheels. However I must take care of a few items before I am ready to get her rolling. One of those items is the seat back/inducer shield.
If you have ever heard a large turbocharger gas turbine run a full power you will know that there is a lot of energy being converted into heat, air pressure and kinetic energy. If anything should come out of balance while the engine is running look out!!! It really is something to be taken very seriously especially when in close proximity to a running engine.
From the very beginning I have planned on positioning the GR-7 behind the jet bikes seat and not under it for this very reason. I definitely want to stay out of the rotational plane of the turbine in case of a catastrophic failure. However just being near the engine is a risky thing so I must try to minimize that risk within reason.
To help reduce possible exposure to ballistic engine parts I fabricated a steel protective seat back that will hopefully protect my “assets” from any possible mishaps. The seat back will not guarantee complete safety but definitely help reduce the risk of injury on this already “dangerous” ride. I used some .090” x 1/2” square tubing to make up a frame and welded it directly to the front frame as seen below.
