Hi All,
new to this metalworking stuff, ............SNIP............. trouble
is,
Imperial size tubing was a good fit into the next size ID, so
telescopic sections could be made easily. All thats available now is
Metric sizing, and its too sloppy a fit into the next size up.


Ah, yes!

Yet another "improvement" brought about by metrification of the world......
