Bryce I would like to see pictures of the locomotives you built? Do you have any?

Anybody can bend .250" or 1.00" 1018 in their hands if the given material is long enough. Try bending the material that is 1.00" in lentgh in your hands and let me know how that works out for you. I think you may be confused about my position. I am not disagreeing that the vertical stays on a crown ...

I just spoke with a good friend of mine who is a mechanical Engineer who got his bachelor degree from CSU Sacramento. He said the shear strength of .250" dia. 1018 steel is 4080 lbs. .375" can handle 6300 lbs in bending and 9,150 lbs in shear. That would be a lot safer. A 5/16" diameter would give y...

Does anybody know anything about the copyright infringement laws? There is a concern about posting some pictures of drawings from Allen Models and Kozo. If it is an issue, I can email the photos to whomever wants them. I do not want anybody to get in trouble

just resent them to the correct email address

As far as my welding capabilities go: I used to work for a company called Barrier Systems INC www.barriersystemsinc.com, and was a welder/fabricator. We built highway safety products and machines and were certified through the state of California for doing work for CalTrans. All of our welds and equ...

I just sent Chris a few photos to post for me. The boiler drawing for the CP173 is from RRSC and is for a copper boiler using. We used 5.500" DOM with .250" wall and has an OD of 6.00" and has been honed for use in hydraulic cylinders. The real larger section is 7.500" OD with .312" wall. I have the...

Will do buddy. I'll send em tomorrow morning when I get to my shop. Thanks Chris.

I have a few drawings for 1.5" scale boilers. I can email them to someone if they can post them. My laptop isn't the greatest and I don't think I can do it from my iPhone.

I'll have to email some pictures to you. My laptop sucks and I cannot resize pictures to fit this forum.

The girders on the top of the crown sheet are .375" x .750" x 7.00". The amount of pressure to bend the girders, distort the crown sheet and bend the stays is much more than what is generated. The second reason why we went went this design is that the throttle body lies right in the center of the cr...

The shear forces again are much greater than the operating boiler pressure and even the pressure the boiler can produce. Gene Allen boilers do not have any vertical stays on them either, they have the girders on the crown sheet. They are relieved on the bottom to allow water circulation. So are all ...
