Machining, making parts and equipment... My cider-maker / cider

So not easily, perhaps shortening a bolt but not to the full custom extent I
would otherwise suggest, like the small piston in the cylinder end cap.
Experimenting is difficult when you are limited to only what you can afford
to buy. My shop is what an inventor would have dreamed of in 1960 though
perhaps not today, after 50~60 years of wear.

How about electronic test equipment? Capturing the brief peak value from an
analog pressure sensor during rapid cycling will be difficult without a
digital storage oscilloscope.
