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...

Re: Johnson 920SS Furnace questions

It looks like you’re missing the blower, the two inlet pipes carry a fuel air mix and fire simultaneously. Attached is a photo of my furnace which is an older model, but is similar in design

Re: Johnson 920SS Furnace questions

Johnson is still in business, they’re in Iowa, search them on the internet and contact them, their representatives are very helpful and can provide a parts list. Then check out Acme Controls in Chicago for the parts.

Re: Could an end mill be used for slab milling

Climb milling is certain death on my mill. I missed a scribe mark on a side rod I was working on and figured I’d sneak up on it with a little climb milling to the mark. Bad idea, with the lost motion in the the table lead screw, the cutter grabbed the work and ruined the part, bent the arbor and chi...

Re: Could an end mill be used for slab milling

‘That’s why they call them end mills’, got it! I have plenty of horizontal mill cutters, but I also have 3 milk crates of large end mills that I’ve been tripping over for the last 25 years, thought that I’d be able to use them for something, guess not.
