Re: Hi Tech Details flexible rubber air hoses

Or if you're as lazy as I am, you use your set of fine, tapered reamers
to enlarge holes... Much easier than knowing exactly which drill bit size
to use for each application...

The brass brackets are from Precision Scale, Part No. 39156. I first drill out the hole in the bracket for the air hose using a No. 77 and then finish up with a No. 74 drill bit. The hole for the pin to mount the bracket to the freight car is a No. 73 drill bit...
