I will need a faceplate to make modifications to a specific watch case to fit the movement or just to broaden my capabilities. It must be DIY of course :) Looking for simple designs like these:

But it is not clear what the cranks at the outboard of the clamps are used for. Are they necessary?

"But it is not clear what the cranks at the outboard of the clamps are used for. Are they necessary?"

They are like small toolmakers clamps and are used for clamping thin plates.  The slots in the faceplate allow easy positioning of the clamps/job to be turned.

If you know how a toolmakers clamp works it should be self explanatory.

Hehe, i only know that it is used to turn plates and such. Never used one before.

I just think that the screws at the back are to tighten the workpiece. But those other screw??? What they do?

Here's one off my Boley lathe.  

You adjust the clamps until they gently grip the part that you wish to machine.  Once you have positioned the part correctly, you tighten the knurled nuts at the back of the plate to grip the part really tightly.

AAhhhhhh!  Now i got it :) That nut at the front is to adjust the clamp to the workpiece thickness, that the clamp will stay parallel to the faceplate! Thank You for the excellent pictures. Now i can see that spring as well. :woohoo-jumping-smiley-emoticon:

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

      If you are having counter tops ( i think thats the amercan term ) and some cupboards underneath where you dont require working legroom then that corner doesn't have to be a difficult access void. Lazy susans , we ( kitchen fitters ) call them cabinet carousels or you could just have two adjacent doors with a corner post fixed to one of them, though it does make for a long reach to get to the very corner. But a carousel is a good access solution, also there are sliding steel baskets available but these are bloody expensive and typically problematic, i really think they are a crap idea. What i like about fully fitted worktops, very tidy looking, no loss of space, and sidewards pinged parts are hopefully going to stay worktop side and not end up crunched on the floor.

      Aren't corners of rooms a bugger though as it is really difficult to use the space underneath the intersection of the two benchtops. Lazy Susans are an idea I suppose. Somewhere to be able to put tools/soldering iron/testing machines that aren't needed on the bench top all the time. It is a bit tight in there, but at least I won't have to move great distances to get to another area. I need to get hold of another chair to have at the cleaning bench. I'll stand all the time at the lathe and I already have the stool for the workbench. Need to get the power sorted now and move the LED lights for over the workbench. There are four downlight in the ceiling that are currently halogen bulbs. Really quite bright so that's good. Ceiling fan as well. What else could one hope for?

      AS 554 from 1930

      By Neverenoughwatches · Posted

      So all that glitters is not gold when it comes to buying from ebay ( in fact very very rarely) i bought this as554 a few months ago. It was it's dial that attracted me to the joblot, which turned out to be printed on a postcard, that was the first red flag. During disassembly many faults were discovered as listed above,  but i was prepared to soldier on and see what i could achieve. I managed to make a setting lever for it which was a great learning experience and also correctly shape and de rust the hairspring.  Turning my attention to the balance assembly i have hit a road block. The staff broke when removing the roller but that wasn't so much of an issue as it was quite deformed anyway.  I also had several AS554 staffs that I could replace it with, problem is they dont measure up the same. I thought i had identified the movement correctly but what i think has happened is some heavy modification has taken place to make an incorrect staff fit. A nos staff is a slack fit on the balance wheel, the roller and the collet. The balance wheel has also been filed to within an inch of its life. I'm starting to doubt my identification of the movement either that or someone has converted the movement into a pure nugget of trash. Bit disappointed as i managed to get the train to spin lovely and put a good few hours into the setting lever. A balance complete might be the only option if one is available but you know when you are just wasting money. My thoughts are to make and modify something else to fit and work if that is possible, any ideas anyone ?

      My second iteration. Cleaning to be underneath the towel rails. That makes sense. Moved the fridge and the maching/printing table around to the right. Changed the lathe to be used over the end of the bench. Not much room in front of the 3D printer, but you don't have to stand there while it is doing its thing. I may swap the fridge and the machining/printing bench yet. Not sure. And the 'doing' area. The power that was brought in for tha spa was 30A I think, so there will be more power than I need. I will have to check how level the benches are as well as find a spot for the movement testing rig to go. The tiles do have a fall toward the drain so I will have to work something out to be able to level the rig easily no matter where I put it. I'm also going to cut some slots in the bottom for pendulum clearance and some squares in the top section to be able to better see the movement. I'm getting more excited now.
