Balanced Air Brakes from Scratch: Difference between revisions

Revision as of 22:06, 30 September 2015

I started with the air tank. It is constructed using 2 inch diameter PVC pipe (schedule 40) with a pair of caps. A hole was drilled and tapped for 10-32 threads to accept a Clippard fitting. An adhesive dot was placed over the hole before painting.
PVC glue was applied to the threaded hole before inserting the Clippart CT4 1/16 hose barb fitting. Be careful with the glue. As you can see it will remove paint.
Here is a spread of Clippard parts used for the balanced air brake system.
In an effort to save money I decided to cut brakes from a ring of aluminum purchased from [www.mcmaster.com McMaster-Carr]. The pipe has a 4 inch inside diameter and a 6 inch outside diameter.
A 1/2 inch width of the aluminum pipe was parted off on the lathe. Here it has been blued and marked for cutting.
