That was my thinking as well...............until I tried a friend's & found that I am not a bullpup kind of guy.
In fact, he has 3 different bullpups (which he rarely shoots) & I thought they all seemed kind of cantankerous. Quickly wrote them off my wanted list. But they are very popular, so................
A parts kit is all fine & well, but the theme of this thread is eye candy. Where are the pics of this dreamy 7.62x39 shooter?
I know I am not the only enthusiast here. Do I need to prime the pump further?
I am aware that some people have an innate fear or dislike of guns (I used to be 1 of you). If so, I bow to your convictions.
However, for those who understand & appreciate the beauty & power of these inanimate objects that can be used for either good or evil -- depending on the intentions of the human in possession of them -- I think it is time for another thread of cool pea-shooter candy.
Here are a couple of mine to start things off............
The timezone course is very good & useful for getting your feet wet. But, as was said above, it is simply an introduction & does not make you a watchmaker. After successful completion of the course, you will be able to overhaul a working ETA movement, but diagnostics/repair will require much more.
Yes & the face should be whiter (less yellowish), smoother (less gravely) & with a bit more space between the bottom of the red line @ 12 & the top of the coronet. The colors should be a bit darker. Otherwise, pretty good.
Most watchmakers' hesitancy to perform routine poising results from a simple cost/benefit analysis.
In order to repair an errant movement, I must occasionally sort out a mangled hair spring. But I do that because I have no other choice. This is not because I lack the skills, but because the potential upside (questionable improvement in timing consistency) is far outweighed by the potential downside (of hairspring damage). & this is amplified when working on vintage Rolex pieces where replacement 'springs are expensive & difficult (often nearly impossible) to come by. Why tempt fate for what is often little or no return since factory-set poising rarely needs to be corrected during normal use. This is why I questioned your watchmaker's choice of routine poising.
I do not know any watchmakers (including myself) who poise the balance as part of a routine service. In fact, unless there is a specific problem with the balance, I cannot think why you would disassemble it in the 1st place. The only time I would poise a balance is when replacing/repairing the hairspring, balance wheel or balance screws.
The 103x caliber is a relatively easy movement for an experienced watchmaker to work on. Trouble is getting parts, since Rolex has not manufactured new 103x parts for decades. But, if you are patient & have deep pockets, they can be found.
If you cannot locate a local Rolex certified service tech, try Bob Ridley.
