Is there a way to resize a tube without a reamer for high pressure stuff? I need to use a piston for something (I won't go into details) and I don't have the money for the reamer so I dunno if I could use something else? I have 10mm (inner diameter) and 9mm tubes, is there a way to get one to around 9.7mm? I was thinking about electroplating it but I dont know how that would work, are there any other ways I can make the tubes smaller/ bigger?

If you can't even afford a reamer, you obviously can't afford any of the other tools you might use to do this. You can't do it with a hacksaw.

If you got a gas stove or propane torch. Heat it up.and dip.it in water. Keep repeating it will.open it up a tiny bit every time. It might fuck the temper up but I've done this to.impact sockets and they worked fine.

Just look up how barrels were made back in the day mate, we've been making guns for hundreds of years.
Btw it'll be way more expensive than a $30 reamer

sure OP just first check your calculations through a fluid dynamics app and compare the result to your data.. am sure all is good to go if variances are +/- 50% from your data points. maybe just ease up into the max pressure range just to be sure.. post results OP
