- How can I put a pressure gauge on a metal cylinder while maintaining vacuum, using only a lathe and/or a bench drill?
https://www.flairespresso.com/product-page/flair-signature made a manual espresso machine and specify using 30 lb of pressure in the manual. In order to determine the correct pressure, they literally tell the user to push down on a kitchen scale. I'm considering a competing product, and that seemed like a rather obvious oversight. Surely there's an economical analog pressure gauge on the market that can be attached to the assembly? For instance, a cheap blood pressure monitor costs ~$35. Surely it's sufficiently accurate?
Now, the system I have in mind uses a cylinder that may or may not have pre-attached valves. Assuming even the predrilled valve is the right size, how do I attach such a gauge without compromising working pressure and volume? If there is no valve (a solid cylinder) do I have any way to attach one using only a lathe and/or drill press (ie no welding)?
Many thanks in advance
