thank gawd
someone else who KNOWS how to use a ratchet
the perceived use that i found for ratcheting open enders was with the 4 engine mounting bolts on my 2 scott bonners
there's not quite enough room for the l.h. rear mounting bolt to fit my ratcheting ring spanner
so, cracking them all with a normal ring spanner, i couldn't do aforementioned bolt. it looked like the ratcheting open ender might have been just the ticket
or maybe it's just a bit more chrome for my toolbox ;-)
t/y again mr G,another well reasoned reply
