Can't do alum as the arbour is metal. I did try a drill in my dremel. But was unable to hold it secure. Need a lathe. Still thinking about one of those 9 in 1 lathes on Ali. -

All the seitz anvils and pushers fit the 4mm clone and I use my Star stumps in the clone base as well. Its not a definite answer but Bergeon and Star lathe accessories are compatible so its possible the staking tool is the same fit. Try contacting Cousins for an accurate measurement. -
Thanks @VWatchie - I didn’t know that, I thought they’d be suitable for wrist watch sized cannon pinions, but maybe not. What’s your experience of the Bergeon 4733? Big expense for a set of end cutters with a threaded screw, but no-one else makes them, there aren’t any clones and I might not succeed in my quest to build @Canthus’ toenail clipper tool to do the job. There’s a B 4733 sitting in my Cousins shopping cart but I’m exploring other options before I buy it. I’d love to hear your experience of the 4733.

Yes, Nev, that’s exactly what’s happening. The bit is sliding all over the chrome surface and can’t get a bite into the underlying steel. I’m using a cobalt bit. I’ve used a punch. They’re quite the tough toenail clippers. I might have to dig a bigger pit through the chrome with something else and see if I get some tooth that way. I was hoping there’d be a bit to deal with this, but I’ll keep trying and might swap to a tungsten carbide bit and see if I have any luck. Thanks for your comments.

I can't answer your question right now but I have these in my Seitz jewelling tool and my impression is that they are made for large, pocket watch size, cannon pinions. I prefer the Cannon Pinion Tightening Tool, Bergeon 4733. Perhaps the pusher and stump could be dressed to work better with small and normal cannon pinions!?
