Small Ba box spanners

[Speedy Builder5Participant @speedybuilder5]

Following on from my enquiry about small head Hex bolts, I needed a 9Ba box spanner (Nut runner actually). Sorting through the come in handy metal stock box, I found a snapped off telescopic car ariel. One of the sections was about the right size to make a small box spanner. I took an old hex key and ground it such that it would enter the tube. I 'drifted' it into the tube to form the right size hex, then sawed the tube off to length. Cross drilled for a tommy bar and silver soldered it into place. Magic. Perhaps not the strongest, but suits my purpose. I suppose I could get the next sized section tube, slide it over the hex portion and silver solder into place etc.etc

What about a screw with a hex hole to fit that key you used, theres your nut runner. Ian S C

Yes, good idea if you can find one the right size. I forgot to mention that its probably best to find some stainless steel ariel – not the brass ones.

If you have access to the digital archives, there are articles in issue 10 page 72 and issue 71 page 19 of MEW, on making BA spanners/nut runners.
