KJ 66 Casing Dimension


I currently have a KJ66 with the casing made using a Oil Cannister. Due to misalignment problems and a really tight fit between the combustor and casing, I am intending to machine a new casing.

Hence I thought of making the casing with a variable diameter. For the section between the impeller and diffuser, the diameter will be kept the same as per Shreckling's dimensions(107.4mm). From the combustor section onwards, I would increase the diamter to 118.16mm.

Would this idea be feasible ?

Yup. However since I have the opportunity of a full workshop, I am intending to CNC one. Which definitely be better than a camping gas can

Still diggin' holes...
I don't think it will affect the running properties of the engine too much... but I could be wrong of course.

I have used the Campingaz cannisters, and they work fine, which is a small miracle in itself given the thichness of the material and the forces involved. I had no problems aligning and fitting the combustor.

Have you changed the dimensions of the combustor somehow?
