Hello Michael a standard B&Q (Gamma for our Dutch
readers) pipe cutter has too much lateral play to
actually cut with. I used to use them with Heliax.
However for scoring a nice clean mark they are good
enough. Thanks for the reminder.
Problem is that the 0.25" semi rigid that I am working
with has a tinned braid outer not a solid copper jacket
and as such is quite easy to deform.
Pipe cutters work great with solid copper outer semi -

any lateral movement of the blade during rotation.
Maybe there is a high quality version of the cheap pipe
I don't want to get it wrong too often as it's

this as a guide for a knife or fine saw.

Hello I have some N types to put on some

connectors are the correct ones from
The tinned braid outer is extremely tough
and I need to make sure that I
can cut it very clean and square without any
distortion. I suspect that
a very fine toothed saw of some type will be
