Same as for tightening the clamps of transformers. Tighten until it breaks, and then back off half a turn. :-)

I can't really believe that you thought that a compression joint would work "finger tight".
It is down to experience and a little bit of knowledge. Experience gives you the feel for tightness and knowledge that finger tight plus
1 1/2 turns is a very good starting point. Last load of compression joints I did I followed the FT + 1.5T ruke only two weeped another 1/4 to half turn cured those.
You are right about that. But for the first few I was undertightening with a spanner. Experience taught me that I needed to tighten up a bit more - and I've now got a feel for when is tight enough.
