Barrel Arbor Battle


tpt

Recommended Posts

I'm having a pig of a time with my first rebuild.

the barrel arbor has a larger diameter than the centre coil of the mainspring and I just can't get it to sit down in position and engage the spring and pop through the case hole enabling me to get the barrel closed.

Are there any tricks of the trade someone could tell me about here?

I must have watched Mark's film of him doing it 20 times now and I can't see that he has this problem in the slightest.

It's the Seiko 5 7009A still.

 

thanks!

I use a small pin vice to hold the arbour tightly.

This lets me manipulate it easily into place by pushing the arbour in at a slight angle while slightly turning against the direction of winding. Once you have it in place, turn the arbour in the direction of winding to ensure that the hook has located properly with the spring before removing the pin vice and closing the barrel. :)

The barrel arbir holder makes this even easier and its not so expensive

Here is the picture ,there are different diameters, but i have bought one and use it for all modern movements

The pin vice will scar the barrel arbor, the barrel arbor has a hole in the middle which will not svar the arbor, if scared you will have wear on the barrel where it touches the arbor and possibly a weak amplitude

    • Hi @Michael20 I am no furniture man my self but it’s just bits and pieces I have picked up over the years. It just takes patience when dealing with things like the cases but most are veneered plain wood. When they get damp and open up that is a problem
    • I often get an amp drop after i oil the stones with 9415, not sure what difference can be achieved with oiling the teeth.  I guess the oiling surface is very small on a tooth as opposed to on the stones a larger drop might have more drag as the teeth plow through it. I oil with a bristle from a brush now, strangely enough the last movement i oiled five escape teeth and the amp was much higher than i usually get , coincidence ?
    • Who'd have thought to look at the supposed compatible calibres ?  🤔 Frank did 😅
    • I recently helped my mentor to service 7 Seikos and he told me not to lubricate the pallets. His reason was from his experience from the advanced classes that he conducted, his students all ended up with worse amplitudes after oiling the pallets. I have to admit that I had the same problem when I oiled the exit jewel, like so many videos on YouTube show. I actually ended up with worse amplitude.  But now I oil the escapement by oiling the teeth of the escape wheel. I think Rolex used to train their technicians this way. I find that I get about 20° -40° increase in amplitude oiling the escapement this way. I've only started playing with epilame recently. I got a bottle from a Chinese seller on AliExpress. It's supposed to be Episurf Neo but everything on the bottle is in Chinese. When the bottle arrived, half of it had evaporated or leaked. And when I brushed on a thin layer on a mirror, it dries rather slowly and even feels a bit tacky. When I did the oil spread test, like my experience with stearic acid, the treated and untreated surface of the mirror yielded similar results. The contact angle of the oil drop looked about the same for both the treated and untreated surface. When I epilamed an actual pallet fork, the escapement was so sluggish that I couldn't even get 180° amplitude. I dunno if I got conned by the seller but the results are just not convincing.
    • I usually just use 2 pair of pliers to remove the roller ( just kidding  🤔 )  I want one,I have an adjustable free standing one. But i really like the little bradux tool that nips under the roller with two tapered jaws that lift it off. You can get under a scope with it to see in detail how the job is going. There is some technique involved to stop you chopping the staff, doesn't particularly matter if the staff is already broken but it naffs up the tool's jaws if you crunch the staff, and the jaws need to be in good shape to prevent damaging the roller. But well worth a try if you've never used one and you can find one that hasn't been misused or buy a one new. The trick is to keep one of your fingers between the two arms to soften the squeeze, with a little practice its a handy little to. I will now prepare myself for an onslaught of negative feedback on it 🤣
