Metamec, the cheap throw away.


Squiffything

Recommended Posts

I had another look and will inform you of the things that stand out.

The hammer is in the wrong place (can be fixed) it would hit the wall.

The pendulum bob and the hook at the top of the pendulum are the only original bits of it and that is debatable.

Looking at the movement, the escapement pinion at the cog end looks bent.

The pinions if you look across the clock are not parallel, the escapement pinion to the fly/fan is way off parallel as is the pallets to the other two above, if this was just and angle thing the latter 2 would be the same offset angle, however they contradict themselves.

If you wanted a clock to keep and be proud to have on your wall then this is not it as you would need to get an original pendulum and fix all that is wrong with it, and the cost would end up more than the clock is worth. 

These clocks come on eBay in Oz a lot so there must be many more in the UK and USA that are all original and cost maybe around 200 quid that still need fixing however you would have an all original clock.

The movement is original so it should give you an idea of what to look for.

Soak it up.....:phew:

Thanks Jimmy, it’s a lovely looking thing and at the price would have made a nice little project but as there is little left of the original not worth the investment. 

As mentioned before I’m after picking up cheap movements to learn about. I have spoken to the guys at the BHI and they recommend that I try and get hands on experience along side doing the course. As there are few clock repair guys around it’s difficult so building up a collection of movements to work on is one way to go.

I’m working on the metemac again. The balance spring is out. It’s deffo cupped as Jimmy said so a complete dismantle and rebuild. It’s now a little more like it should be. 

Damn I enjoy this. I can spend hours pulling these things apart and rebuilding and not even notice the time that has passed. I notice I’m getting quicker as the familiarity sinks in. 

Error made earlier though, I didn’t quite get the main spring ring set properly when I let it go, it pinged a nut across the room like a bullet and shot the cat. He’s old and a little constipated but man did he crap himself. Loosened up a load :)

The cat looks guilty, I bet it is thinking " ignore me and my lunch for stupid clocks will you"

I remember watching a doco about apprentice clock/watchmakers in Switzerland years ago and a girl lost a screw off a watch on the floor, 5 of them looked for it for about 30 minutes and this floor was white and spotless, they did find it, so there is hope Squiffything.

When working on stuff that might fly away on the ISS, they use a glove box. Maybe I need to build myself one of those.

I'm not sure how I would get my magnification arrangements to work with it though.

I found it! Woohoo. It was embedded in the rear section of the dogs hind quarter. Talk about tearing him a new ring! It’s ok he’s settled down a bit now but it’s interesting watching him squirt out a double walnut whip ;)

    • I'm assuming that every time you set the watch you are work hardening the detent spring, maximum hardening is  where it meets the plate due to maximum deflection.   That's why it snaps there.  The Young's modulus may be the same but after it's reached its maximum yeid strength it breaks.  My mechanic engineering is very rusty, correct me if I'm wrong. 
    • Ah ok yes that makes sense to polish it where the arm starts to form from the body of the bridge, i thought you meant the underneath of all the arm.
    • this is something I've never quite understood about the some of the Swiss companies. In 1957 Omega was using 9010 for the keyless parts with epilam. there's been a slow migration towards using heavier lubrication's but still typically oils and epilam to keep them in place. When it seems like 9504 works so much better.  
    • OK, welcome in the world of alarm clocks... I guess the 4th wheel is dished because it is from another movement. If it was not dishet, then it would not mesh with the pinion of the escape wheel, am I right? The marks of wear on the 4th wheel pinion doesn't corespond to the 3th wheel table position, at list this is what i see on the picts. Calculating the rate is easy - there is a formula - BR = T2 x T3 x T4 x T5 x 2 /(P3 x P4 x P5) where T2 - T5 are the counts of the teeth of the wheels tables, and P3 - P5 are the counts of the pinion leaves. Vibrating the balance is easy - grasp for the hairspring where it should stay in the regulator with tweasers, let the balance hang on the hairspring while the downside staff tip rests on glass surface. Then make the balance oscillate and use timer to measure the time for let say 50 oscillations, or count the oscillations for let say 30 seconds. You must do the free oscillations test to check the balance staff tips and the cone cup bearings for wear. This kind of staffs wear and need resharpening to restore the normal function of the balance.
    • Glue a nut to the barrel lid, insert a bolt, pull, disolve the glue.  Maybe someone will have a better answer.
