The puller is the easiest thing to make with a lathe and mill here's where a photo of the device is located. https://www.chaski.org/homemachinist/vi ... sure+gauge probably a 15min little project and pretty crude at that.
As for the duplex gauges. I thought it was covered earlier here but the issue became finding a donor gauge that would work in a scale that would be useful, as making bourdon tubes and gearing is something beyond my knowledge or what I think look the market could even bear. Maybe I could make one for the larger scales but definitely not 1.5". If someone's interested in working on the project to make a few let me know. I would be happy to help with the art work needed as well as trade notes on a donor gauge to use, but I just don't have the time right now to make it all happen.

Any update on the next run for the 200psi version?
Re: Model Steam Pressure Gauges
I was interested in a duplex gauge for air pressure - reservoir pressure on one side and brake cylinder pressure on the other. I spent a bit of time trying to find someone that made them in scale or nearly scale size. The closest I came was a 2" gauge. These were made in India and I suppose available in various pressures but I didn't followup to find out. https://www.indiamart.com/proddetail/du ... 49230.html

Re: Model Steam Pressure Gauges
Duplex would be very interesting, Especially if they could be made like the prototypes. Ive not seen many duplex gauges in the hobby.jkimberln wrote: ↑Tue May 31, 2022 10:05 am I was interested in a duplex gauge for air pressure - reservoir pressure on one side and brake cylinder pressure on the other.

Re: Model Steam Pressure Gauges
Something like these would be cool, but likely a lot of work/$$ to make.

Re: Model Steam Pressure Gauges
Here is an English Smiths gauge, in a 3-3/4” 2-6-2. It reads main res and brake cylinder.

It took a while to make them, but I now have some more of the original and most popular 2" 200psig gauges available to sell at the following website;
