Gauge glass fitting

Post by makinsmoke » Tue Mar 13, 2018 3:21 pm

Many locomotives I’ve seen (full size) have a
steam fitting or tube on the engineers side that the try cocks are screwed into on one side.
On the other, two valves attach the gauge glass.

Usually the fireman’s side is installed like most
model locos, top to the boiler top and bottom
to the backhead.

Has anyone modeled them and if not, why not?

Thanks,
Brian

Brian, I think you are referring to a water column. It is on the right in this drawing. Bill Morewood used one on the Raritan.

Hi Brian
I made one 11 years ago. Posted pictures on this forum the link is below . I think the post has received over 16,000 views. There was a big controversy over the use of set screws to hold the face on. Well I didn't make the gauge. I just made the "Serge Column"

ItI worked well but I removed it because the Pennsy locos have small cabs and where I had to mount it was hard to read.

Water column!

Thanks Marty!

Dave, that’s a pretty big piece of equipment for
smaller cabs like you say. Nice work though.

Pros and cons other than the size eating up cab space?

Interesting that Baldwin specified copper pipe for the piping.

Brian,

Yes, Baldwin did use copper tubing for much of the cab needs. It is usually very heavy wall material often with custom ends brazed on complete with coupling rings.

Recently I was tasked with the manufacture of a replacement steam supply line to a lubricator. The supply line was 1 inch in diameter and the wall thickness of the copper was .125 inch. Plenty of strength for the task at hand.
