AS1903 train assembly problem

[tonydagee]

Hi all, thanks for the insights, very helpful.

I’m fairly certain that in this case, it was down to my lack of patience and skill.

some trains are easier than other, we all know that.But developing skill and knowledge is a journey, and I’m convinced that the only way one learns anything worthwhile is by making lots and lots of mistakes initially.

Watch repair is a solitary pursuit, which is why I  love it…

But it’s great to know the support of the community is there when I need it.

Well, just when we think it’s all over
Maybe I should deem this a new topic,but here goes…

assembly completed, timegrapher showed really good readings(>300degrees)perfect to start the regulation process.

Instead of letting things  be, I decided to immerse the balance one last time in hexane for decontamination and thereafter, well readings went haywire, no more than 150degrees   If measurable at all.

There is good force at the pallets, everything is clean, nothing bent…

How would you proceed.?

Better leave well alone next time,I think…

will Dorothy ever get back to Kansas?

When the timing machine showed greater than 300  Visually what did the balance wheel look like? In other words didn't really look like it was going greater than 300?

As the only thing you supposedly touched was the balance wheel look carefully at the balance wheel. See if hairspring is flat and whether it's touching the balance arms etc.

BTW   The movement is demagnetised
