      Hello folks,
      I’ve been looking at purchasing a set of smoothing and cutting broaches for clocks and pocket watches. I’m not sure of the size ranges I should be looking at. If someone might throw me a clue, I’d surely appreciate it.

        Ren I started with these for cutting. http://timesavers.com/i-8944714-10-piece-cutting-broach-set-for-large-clocks-031-188.html
        Bought this set for smoothing. http://timesavers.com/i-9530638-6-piece-swiss-smoothing-broach-set-047-118.html

        From there I added on a as needed basis.

          Hey Ren, I think the same as Bernie, 0.05mm – 3mm
          I’m not too familiar with clock pivot diameters so maybe you’ll need a larger size than 3mm

          Ain’t tool buying addictive and loads of fun, or is that just moi 😆


            Thank you guys!!


              That size range is good, french clocks can go smaller than .5mm on some of the pivots, the fly pivot I did for Jan which has gone missing in the post was around .4mm. Some centre arbor bushes are much bigger than 3mm. If you intend to mess about with lever platforms you will find a lot of those are not fully jewelled and will need bushing, you are then going down to watchmakers broaches(which will also be handy for a lot of early european pocket watches). Barrel bushing uses around 6mm broaches and I now have a nice collection of tapered reamers for bigger holes too.
