1 There’s no room for a ‘wrist’ on the olive that goes with this threaded sleeve, leav­ing very lit­tle sur­face area for sol­der­ing – the joint may not be strong enough.

2 So I de­cided to form an olive with a brake pipe flar­ing tool in­stead. This old Sykes Pick­a­vant kit flares pipes from 3/16in to 3/8in di­am­e­ter.

3 The pipe is gripped in ta­per-bod­ied, ser­rated chucks which tighten into the frame, then the flar­ing arbor is pressed into the end of the pipe with a T-han­dled screw.

4 It’s worth an­neal­ing the pipe first by heat­ing to red hot and quench­ing. The re­sult is a very neat dou­ble flare that can’t pull off the end of the pipe.
