I think this has run it’s course now. The great reveal🎤🤫

It is for recutting the valve face seal for engine valves.

The valve is held in the jaws and moved forward with the fine screw thread against the cutter. It is then rotated by the handle clamped to the valve stem until a smooth shiny seat is formed. It sounds quite ‘agricultural’ but I can assure you it works. Think. BMC, Ford and earlier vehicles.

I am sure it would not work on moder very hard engine valves.

Would you like another one ?? NO. as Pompey– says. I will get my coat.😁

    Flat_Eric It is the only one I have seen, there are a couple of similar items on the I/net but not the same.

      Believe it or not, I was actually wondering whether it was for refacing valves the other day. Unfortunately, I didn’t commit my wondering to type.

          For blowing a variety of different sized bubbles by waving about ??

            Wow that was a quick resolution! I was imagining something to do with woolen yarn or crochet or something. Doesn’t look substantial enough to deal with dough, but I stand corrected!

            Yup, I wouldn’t have known that was a dough whisk.

            Anyone know what this is used for - possibly quite niche, but no more so than the last two. I use it regularly and think it is genius.

            Nope - added another photo to show scale.

            It looks like those T-piece splitters for greenhouse irrigation, assuming it is hollow.

            Nice pen BTW.

              Hotmetal Thanks, work desk and work pen. Just noticed how manky my scabby work keyboard is!

              Not for irrigation - it is hollow though.
