Where to find these larger staking punches?

Hi guys, I currently am trying to find a few staking punches but with a hole diameter of between 3.7 and 5.5mm, so 4 and 5 mm would hopefully suffice. Smaller diameter ones are easy to find but not this size. They are for fixing a clock wheel back onto its new pinion.

Note one is a spreader 9curved face) the other 2 flat faced, all hollow to fit over the arbour.

Can anyone point me in the right direction?

Why not make your own?

As Roy, you could well find them hiding, in a piece of suitable bar stock, in your workshop.

Yes am on the case just thought I would ask first but it's one of those that you ask half knowing the answer.

If you are staking brass, they would not require hardening.

Yes thanks for posts, i have made 4, to curved , 2 flat bottomed. I guess I will have to make quite a few more staking stumps despite have over 100...there is never the right one. i have made this 4 out of silver steel so I will tomorrow harden and temper (not sure if i need to temper) as I will be hitting steel (part of arbour / pinion to rivet a wheel on.

"There is never the right one" is why you make them as you need them. Especially for things like clocks which have lots of one-off parts made to fit each other.

If you harden it properly you will need to temper

A little of topic but I have never seen a staking tool for larger diameter punches or is that due to my poor eye sight? They all seem to be for 4.7 mm diameter punches which is not a very handy choice, 5.0 mm would be much more practical. Niko.

Yes agreed you will always need one that you haven't got.

P.S. ... J. Malcolm Wild offers a larger staking tool, which includes a reducing sleeve for standard diameter stakes :

This appears to share some characteristics with the Geo. H. Thomas design which formed part of the Universal Pillar Tool. [but there are only so many ways to skin a cat].

Yes, that is of interest, thanks Michael.
