I haven't been doing much watch wise, but lots of work on watch tools.

I ended up needing to make a bunch of parts for a lever action tailstock for a small Schaublin lathe.  I have the factory main casting and quill (the critical parts) but all the auxiliary bits are missing.  The lathe is a duplicate so fortunately I had a set of parts to copy from. 

First is the tailstock drawbar.  Toughest part was it’s a 11.75 mm metric buttress thread.  For those not familair, look at the collet; the flanks are 45 and 5 degrees vs every other thread that is symetrical.  It took longer messing about grinding the tool than cutting the thread, but it worked out well – its for a W12 collets

Next up, is the tailstock lever.  Not particularly difficult, but man, it was a lot of whittling!  Files and die grinder mostly after roughing to shape in the mill.  The turned portion I did by measuring the existing one, making grooves every ½” to the right depth, then roughing and finally finishing by hand turning.  I stuck the dull end of a 1” boring bar out in front of the work grabbed a large radius nose tool (maybe 1.5” radius, ½” tool bit) in a pair of vise grips and went at it as you would with a graver in a watchmakers lathe.

Paint is sprayed via airbrush, with talc in it to reduce the gloss.  In the last pic, I have some touch up to do….the quills were slightly different dia so I had to grind a bit out of the inside so it would fit.

Its watch tool related, but for a sure little different for this site so thought you might find it interesting....now back to the salt mine!

      I'm going to be setting up a decent little workshop here at home.

      By Michael1962 · Posted

      Well I put the spa on Gumtree (selling service) to try and sell it as it only needs a recirc pump to get it going. However, it weighs circa 250kg, so there's 4 fairly strong guys, and I would have to remove the sliding door in the room completely to be able to get it out, as well as clearing out a multitude of potted plants and the Alfresco outdoor setting to be able to get it out. Then move nearly everything in the back of the garage to be able to push it through to the front of the house. I would also need to hire furniture skates to be able to shift it around as carrying it is out of the question. Then someone would need a trailer to get it to their place as you won't get it on the back of a ute. So, the only answer is, out with the reciprocating saw and cut it all up into manageable pieces. Crying shame as it is in really good nick. I was only asking $1,500 and only got two bites, but it would only take something to go wrong with removing the sliding door etc that everything I make on the sale could go out the door on repairs etc. It would have been nice to be able to turn it into tools etc, but que sera sera. I don't know about the rest of the world, but there just seems to be very little interest from people wanting to buy things secondhand.

      I would like to see the movement. The watch is the movement. Anyone can print a name on a dial and sell it as "the maker".

      What are these Seitz B-Jewels?

      By VWatchie · Posted

      Thanks for your answers! There seems to be a contradiction between these two answers, so perhaps I need to clarify. The flat and convex jewels look identical on the side facing away from the pivot shoulder. That is, there is an oil reservoir. I don't know if that changes anything but I thought it was safest to clarify since I didn't include a picture of the jewels from the opposite side.

      unfortunately paying attention to details bumps up the cost. Which is why they shortchange on manufacturing steps if they can.

      Introduction

      By oldhippy · Posted

      Thank you for your introduction and welcome to this friendly forum. We all look forward to your contributions and continued involvement.  When it comes to tools buy the best you can afford a good set of watch makers screwdrivers if you look after them will last you a life time. I recommend Dumont tweezers Number 3 and number 5 for fine work, you can build up from there. You will need different strength eye glasses. Some now like to work using a microscope. Pliers the box jointed ones are best they don't go out of line.
