I am looking at having a go at a Stirling engine the plans i am looking at call for a test tube 15.6mm OD 54.5mm long.
I realise that if i got a test tube 16mm OD a small change to the drawing would not be a problem but all the tubes i have seen on the Internet either have a rim around the neck or are to long.
So my question is can i get a tube that is to long and have a rim and cut it down obviously without breaking it to the desired size. And if so how do i go about it. Any advice would be grateful.
Thank you.
