Re: Vacuum Ejector Drawing / Guidance

I can't remember what I got on the small one but i think 17 or 18. you won't get a total vacuum with these like you would with a pump. With air brakes you only get what the air pressure is so at some point you will loose brakes. On my Hunslet i have just been pulling Mr. Johnson into reverse and tha...

Re: Vacuum Ejector Drawing / Guidance

I've built a couple of them. You may not get 20" at 60#. If you need more power then use a larger diaphragm. I have 2 drawings in Autocad if you are interested. one is from Dcokstader.

Re: Union nuts & cones?

I also have a CAD drawing of these from 1/8 to 3/8 if you like. The tricky part is making the male thread for the nut. all of my dies are split dies and I have to open them up when cutting the thread or else the thread will be too small and the nut will be a really sloppy fit. These are fun to make ...

Re: dual crosshead pump plumbing?

Hmmm. I was worried about the inlet side. He has boiler checks already and will add another one for the injector. I think separating the pumps would be a better way but a bit more complicated.
Thanks.

dual crosshead pump plumbing?

A friend has an American 7+ ga. that has dual crosshead pumps. He is restoring the engine and wants to know the best way to plumb the pumps. As I remember it I think the outlets are connected together across the engine. The bigger question is about the supply and bypass lines.
Thanks,
