Pipe bell mouth


The plan is to use one of Keith's 3D printed pipe bell mounts from high temp heat treated PLA. Keith has been using these pipe cones for a couple of years with great success. This cone is sized for the K-45 and is designed to use the rear holes of the turbine mount to index the proper spacing from turbine tail cone to the leading edge of the pipe. As the photo shows here the K-45 mounts are larger than the X45 so Keith sent me a new CAD file for the X-45.

Printing started with regular PLA since my high temp filament had not been ordered yet


Pipe cone for X-45 indexed to rear turbine mounts for a 20mm spacing from leading edge of pipe.


The design had to be adjusted slightly for the inside of the cone mounting arms to clear he turbine mounting clamp bolts.
