Word of caution when drilling thru boiler shells, make sure the drill bit can't grab as it breaks thru and go in deep enough to poke a hole in a boiler tube. And that a tap will not project thru and do the same. Saw it happen to someone once on a copper boiler and the tube had to be replaced.

Re: Water pressure gauge
I pipe my bypass line back to the tender and position it where the discharge can be seen thru a port when the bypass is open. Puting your finger against the line shows if its pumping pressue as well. Not a gage, but works well for me on 3 locomotives.

Re: How to increase tightness between splined pieces?
Is the splinded shaft
Large enough to drill and tap with NPT thread. Spilt the shaft with 2 or 3 saw cuts and then put on a pipe plug to rap and the shaft into the female part. There are flush pipe plugs that would not stick out when assembled.

A used one inch wide x 42 inch belt sander, invaluable for deburing, chamfering and rounding edges on parts.

Re: Ash Pan Latch Ideas?
I built a ash pan with the sliding sloted dump simular to Steve's. I extended the slider on the back side and added a screwed on boss that lets the sliding for to be pulled open and pushed shut with the poker.
Works great.

Re: Bad vibrations; is it in my head?
I have had that happen to me on my 1928 9" South Bend. It happens when the cross slide was set at very shallow angle to the bed. That ment the tool holder was almost 90 degrees relative to the crosslide, in which case it is not very rigid. I had had it set to do a very shallow taper on a valve ...

And then checked for same when set i...

Re: Eye bolt rating
You can get next day shipment from McMaster Carr or the other major suppliers. Little more cost but fast service. I agree with not using bent eye bolts for lifting. Nothing but an accident waiting to happen. I would bolt on a piece of angle iron drilled to make a lifting eye in a pinch. That I calcu...
