Re: Turning radius

do you have a CAD system available to you?

it is actually easier to draw than explain

you need to know the fixed wheel base, the side-2-side play in the axles and the 'nominal' rail spacing.

Re: Cast Iron Steam Water Pump

either option will work...been there done that on several occasions.

Advantage to bronze sleeve and O-rings is that you can virtually forget them.

If you don't like pressed in liners, you can always glue them in with high-temp Loctite (done that also)

Re: Cast Iron Steam Water Pump

I have honed cast iron bores to size and they are still rough on O-rings.

'tis the nature of the beast. A thin bronze liner is well worth the effort.

Re: Jet 1336 PBD Lathe

I had exactly the same thing happen to my Select 1024 -> but it was with a QTCP attached and a cut-off tool dug in and "off with it's head"

the marketing of Taiwan machines under multiple names was/is not limited to the 1980's - they are still doing it

Re: Harpur/Allen Mogul Smokebox Configuration

soft balls are generally not a good idea unless you have a broad, flat seat at a 45 degree angle....even then they are short lived.

Re: Using a steam indicator

the water filled pipes restrict the pressure changes which come VERY QUICKLY....and give very funky readings as a result.

You have the same problem with very small pipe connections to / from a 'model' indicator.

Re: Harpur/Allen Mogul Smokebox Configuration

slick but not very useful as a feedwater heater considering that it is not actually in the flow of hot air..

yes it will add temperature to the incoming water but...is it worth the nuisance?

Re: Ed Perry

I cannot imagine any reason why a person would want a copper firebox in a steel boiler..especially when the copper probably cost more than my house, farm and all the equipment combined. pictures of two full-size steel boilers with new 1" thick copper fireboxes being installed copper firebox in steel...

Re: Surface plate lapping

The last plate that I had reconditioned was done by 'Rock of Ages'.

I know that Starrett also provides (or used to) that service.

In reality, you are most likely going to have to crate it up and ship it off. Places that provide this service are not as plentiful as car dealers.

Re: Stress Relieving

the difficulties of straightening are proportional to how crooked it is and what tolerance is required.

I would put a center in one end and a follower rest behind the lathe tool and have at it and pray that it stays straight.
