Formed Fireboxes

Post by Marty_Knox » Sat Mar 22, 2014 3:52 pm

Yesterday I picked up a dozen fireboxes I had cut and formed at Weber Steel. From left to right they are Little Engines 1" Atlantic or Pacific, Allen 1 1/2" 0-4-0, Railroad Supply 1 1/2" 0-4-0 or Mogul, and Little Engines 1 1/2" Pacific.

My uncle made one for himself out of 3/16" thick plate, and his has survived many attacks. Incidentally it is also sitting on a 3" pipe dug 3-4 feet down and concreted in... If you used one of those fire boxes... Well it would survive and onslaught from a couple howitzers!

Marty, would the Allen 1 1/2" 0-4-0 box be for Chloe and derivatives?

No, it is for our new 0-4-0 switcher using Mogul cylinders and valve gear, Consolidation drivers, and an American cab.

Sounds interesting Marty. This is the first I've heard of it. Any more info available on the web? I don't see anything on your web site. Will it be Stephensons or Walschaerts?

By comparison then, is this firebox for the 1 1/2" 0-4-0 smaller, larger, or about the same as Mogul and Ten Wheeler?

Best,

-Richard

Where these formed cold? I have often wondered if a crown sheet could or should be heated to ease the bending. Thank you Marty .

These were formed cold, with a minimum inside radius of three times the plate thickness. For example, the 1/4" plate has an inside radius of 3/4". On the 5/16" plate the inside radius is 1", since they don't have any 15/16" radius nose dies.

The firebox is wider than the Mogul, but not as long. Not quite as much grate area, but more tubes.

Years ago, the kids thing was driving over mailboxes in my neighborhood. My father got tired of putting it back up, and since he worked for the power company, he had the line crew bring the butt section of a broken off power pole. They planted it about 6 feet deep, and put the mailbox back on top. Come Friday night there was an ungodly crash from the road, and the next morning there was a car with its front bumper wrapped around the pole. Evidentially the kids hit it at about 60 mph. That ended the mailboxes being knocked over.

Ya, those kinds of things were kiddee amusements from time honored pranks. Unfortunaltely we never TP'ed anybodies house that did not deserve it, or paint somebodies car with white tempra paint, and only blew up mailboxes with M-80's around 4rth of july. The advance of those kinds of things without reason, wound up with either bullet proof mailboxes, or 5 gallon buckets on their side on a post. The bullet proof ones caused the trouble when some drunk ran into one and was hurt as the 40 lb box went through the windsheild. Thats why approved mailboxes are annoying plastic, or some form of light sheet metal. Our County has limits on pole discription, and approved boxes to remove all doubt. several ritzy boxes with a brick surround, have had to be taken down as a road hazard, as they lie on the public way, and individuals have no rights to incommode the public way. (or create a hazard to travelers). So tossing a spike board in front of racers or speeders is a criminal act.

You must call the Authorities, and they have no guarentee to answer your complaint.

Without asking, then the answer is a brake press to do the forming cold. My axle press would be challenged to bend 5/16s material of any length. A perfect example of doing what you can, and farming out tough things to those that can do a better job.
Thanks for the views.

They look far stronger than the welded construction I saw 10 years ago. BN
