Re: Atlas shaper

Mike, the ratchet assembly isn’t that simple, there’s an internal gear that would be nearly impossible to duplicate; I believe the entire assembly is die cast in Zamac. The cone pulleys have four steps with a fifth step in the rear pulley for a brake. I use mine from time to time, there are a few th...

Re: EMD F7 in SCALE

Steggy, I have a question about the pivot link in your diagram labeled item #2. Does that link hang vertical when the brakes are off or is it at some angle to vertical? Thank you John

Re: EMD F7 in SCALE

Steggy, I’m using a 24 volt motor and gear train to for propulsion. I’ve been working on a prototype Blomberg truck that I’ve been revising and adjusting to eliminate problems and interferences that I encounter as I work through the build. I’m trying to stay true to the Blomberg design with the bols...

Re: EMD F7 in SCALE

Beautiful work Steggy, I’m going to try and do what you did but in 1” scale. 🤞

Re: 1” scale air brakes

So last night I went through my bucket of scrap plumbing pipe and fittings and cobbled together a 1 cubic inch air tank with a pressure gauge and ran a test on the air pump this morning. Using compressed air starting at 100 psi and dropping to 80 psi the pump produced 1 cubic inch of compressed air ...

Re: 1” scale air brakes

Thanks Keith! There are only a handful of guys running 1” and 3/4” at NJLS these days, never saw a track brake. Thanks again, John

Re: 1” scale air brakes

Keith, track brakes are something I never saw nor heard of, do you have a picture or drawing? Thanks, John

Re: 1” scale air brakes

I guess the first thing to do is determine the productivity and capacity of the pump, but regardless, it doesn’t seem like the best way to go. Steam, air or vacuum, none of my cars are equipped with brakes, and with the variety of obsolete truck brands on the cars, fitting them with brakes isn’t som...

1” scale air brakes

Has anyone had any luck with 1” scale air brakes? I acquired a very nice 1” scale duplex steam driven air pump that may produce 20-30 psi and I have a 1” scale Atlantic that has a functional steam brake system. The steam brakes are more trouble than they are worth, but since I now have an air pump w...

Re: Blomberg Truck Castings

I’ve been working on a 1” scale version of the Blomberg truck and I’m looking for information on the brake hangers and linkage. I’ve been scaling off the IBLS drawing and using photographs to supplement the drawings which has worked so far, but the drawings are not clear enough to duplicate the brak...
