Here is the one I used to test run my Wrenn SS as it was my first turbine I thought it might be a good idea to learn about turbines on the bench. A little agricultural but I thought it was sufficiently strong to contain the beast.

The most memorable moment occured when on the second run when I advanced the throttle towards full power AND the turbine moved.

After bending the throttle stick on the slow down I found that it had moved in the holding straps. This was cured by lining the straps with wet and dry sandpaper.
