...apparently a pair (or even a single) 5C collet block isn't one of them. :(
I had started a project to make a special pin spanner (wrench here in the US) to adjust the headset bearing on my motorcycle. It's going to be one that has six 3.5mm pins in the face with a center clearance pocket to avoid interference with the crown of the 38mm hex nut on the bike. At the 6 points of that 38mm hex are the mating 3.55mm holes, and I wanted my special wrench to fit both the hex (making it longer and the holes (giving it a secure attachment.)

I've made a blank on the lathe out of 303 stainless steel. I just need to pick up a collet block (hex, square or both) to grab onto the .150" long section of 1" diameter. That will allow me to mill the 38mm hex, the center relief contour and rough out the square drive at center.
I think Jeff @ Tools4Cheap.net has some economy ones that'll do. I just can't believe I've not needed them until now. I thought for sure those collet blacks were something I bought for my dad or he bought himself. If one of us did, neither can recall and I can't find them.
Oh well. Project on hold for a week or so. ;)
