Some pipe fittings... Here?s the second set I made, the first one went flying in direction of the scrap box when I realized I had
left not enough space to fit studs and nuts.
Later, I recollected them all: they might do with SH screws, on the ?modern materials? Bernay. I have not checked, yet.
While I was making them, I made myself a tool I should have made ages ago: nothing fancier than a short parting tool,
0.8mm wide, ground so it protrudes from the left of the bit. Works a treat when cutting the runout groove for a thread
against a shoulder.
..and pipe bending.Material is 6.2mm external dia. 4mm bore copper pipe: first of all, I straightened that short piece through forcing a
4mm steel rod through the bore. Results were not that bad.
Next, I chucked the cored pipe into the lathe, and reduced the ends to threading diameter: no way I could do that without
some support into the copper, then used a die to thread one end M6x0.75, the other end M6x1.
When it came to bending the pipe to a ?nice curve?, I wrapped a length of strictly coiled masking tape over it, put a couple
of marks where (I thought*) the curve should start and finish, inserted the 4mm steel rod on the long arm, till it reached
the start position and fitted a flexible core (plastic brushcutter wire, brought to diameter by wrapping some more masking
tape on it) into the other end.
Bent it over a 30mm rod set in the vice, using hands and a piece of 8mm inner dia. tubing to add some lever.
Here it is without the masking tape.
(*) It is obviously too short on the longer arm and too long on the short one, but that can be fixed.
Somehow.
