Truing tool

[rogart63]

Is this some kind of truing tool ? 

Found it on a swedish auction site? And this Seitz press is it anything to buy? Could you buy the stakes for it? It's only the press on auction.

The truing calipers look quite large - maybe more suited to clocks (or maybe bicycle wheels) than watches. The next item is for drilling out staffs to fit a new pivot. See here http://mb.nawcc.org/showthread.php?118580-Escape-wheel-pivot-repair and you will note that there are some key bits missing.

The jewelling press looks to be in good condition, but it's very rare to set sets of stakes second hand without the press. You can buy stakes new, but they are not cheap. https://www.cousinsuk.com/category/jewelling-tools-for-bergeon-kif-inca-seitz.

I bought a used set including press for less than £100 about 18 months ago

Now that you mention it i see what you mean  Very small bicycle wheels . I was thinking if i could buy some broaches to broach out the barrel hole in the mainplate in Seiko movements? And put a jewel there instead?

Be careful buying Seitz jewelling presses without stumps. At some point Seitz decided to change the size of the locating peg on the bottom of the stumps from 3mm to 4mm. You won't be able to fit the new stumps to the press without enlarging the hole in the base. The new pushers will fit as they have always been 4mm but they are expensive, as are the reamers for which you will also need to buy the spindle. These items seem to rarely turn up used unless with a press, however you may find stumps from a staking set will fit. I have a Japanese MKS staking set and the stumps are a perfect fit in my Seitz press (4mm base not the older 3mm). Favorite jewel press stumps also have 4mm pegs and so fit.
