I am thinking about making some things for my workshop. In among them, I shall need some fairly stiff metal - probably tube.
Trouble is, cost of P&P makes online prices quite high. I can get suitable tube locally at a reasonable price and avoid P&P but, so far, have not found anyone to supply threaded both ends tube.
I've never threaded 3/4" galvanised so have little appreciation of how tough it is. Nor have I found a pair of die and die stock that obviously go together!
Yes, I have seen sets of tools (e.g. 1/2",3/4", 1" and 1 1/4") but they are far more in terms both of bits and cost than I need.
Is it easy or hard?
Many many many years ago I "helped" my dad instal galvanised pipework,
from 3/4 up to about 3". Perfectly do-able but it requires elbow grease,
a pipe vice, cutting oil, and (obviously) a threading tool (seem to be
available for less than £50). Alternatively, could you use Dexion
tubing, with the knock-in joints?
As an aside, for cutting I now use a Rage cut-off saw, bought from the
manufacturer as re-furb'ed. It's brilliant and far better than an angle
grinder or a hacksaw.
