Alas, his site has become almost impossible to search unless you already know what you are looking for…so an email might be be...

Re: EMD F7 in SCALE

BDD, makes sense now. Thanks! Here’s a couple of photos I took last month unit in Hawaii, when I was studying brake systems, these are a brake system on a Whitcomb 44 toner center cab. Although in this case there Is only one brake shoe per wheel each side, not two, I suppose because the Whitcomb is ...

Re: Safety valve location

Harold, poor choice of words on my part. Iam happy to accept boiler pressure is generally isothermic, throughout the stream space. However, in a hobby boiler, this pressure is far from static. Boiler pressure changes rapidly and repeatedly due to repewted introduction of feed water, cut off and thro...

Re: EMD F7 in SCALE

BDD, I like the way you have modeled your trucks and brake rigging to represent the actual prototype. This is exactly the kind of brake assembly I would like to replicate on my Center cab rebuild. One thing I missing, and don’t understand fully, is how you would connect your brake cylinder to the br...

Re: Safety valve location

Mike, Iam no expert, but I’ve always heard the safety should be located at the highest point in the system- which allows it to gauge highest pressure. Hence the steam dome is the ideal location. Maybe someone expert in boiler design can join in and clarify...

Re: Anybody experienced with P3 .035 wire?

BDD, Iam traveling at the moment, won’t be able to double check until next week. But Iam sure that’s what the Airgas guy told me to do when I picked up the machine. I did see a welding forum comment that said smaller welders with 1/2” nozzle diameter used 15 cfm, and larger ones with 3/4” required u...

Yep, I misspoke. It is indeed CFM, not psi. So set up at 50cfm. What Miller recommends for this particular machine...
