John will ask this question anyway: how did the watch run before your service? -
I have demagnetised. I would say the hairspring looks fair, mostly evenly spaced though not perfect, no coils touching. I don't have the skills or equipment (an adequate microscope, a good way to remove and replace the hairspring from the balance wheel to work on it) to improve the hairspring so I would need to source a NOS balance complete. I will give it a closer look though. -

Haha ok so let us begin . Yes the oats tin is a temporary modified heat reflector/ retainer until i find something more..... lets say " the part " looking. No not mcgyvered but an A Team special reconstructed spinney thingymabob whirlygig device. The speed of both the drill and hairdryer are controlled by a very sophisticated and complicated piece of apparatus called a " SPEED CONTROLLER " at the extortionate price of £15.99 . No i dont need to hold anything the drill is in a cheap drill stand ( cost £5 for both from a carboot sale ) the travel on the press is 85mm which is enough to lower and raise the basket in and out of the cleaning jars. The " speed controller " 😄 is just a voltage regulator and usable on just about any electrical device to control the speed of a motor or heat output within the full range of a domestic AC electrical supply. Shellaced parts i hand clean and dry separately, i dont risk them at all, shellac will start to melt at around 65 °. The timer , yep an old Smiths timer, i think that was a quid and the white appliance is a food dehydrator, i rarely use that now, i think parts need to be dried quicker than that can achieve. I think thats covered everything. Feel free to ask anything else. Besides the basket you are looking at around 100 quid in total for everything you see here including the ultrasonic and the dehydrator. The ultrasonic i also rarely use , combined with an ammoniated solution ( elma wf pro , which i desperately need to use up and not buy anymore ) and it's cavitation action it is too bloody aggressive imo. I also have something even more diy-ish, simpler, cheaper and more portable that i like for cleaning right next to where i work on my bench. What do you need for cleaning ? A solution that cleans and rinses well that leaves no residue and a device that spins your parts round and around through the solution with some added method of agitation, there are a multitude of ways to achieve that and it does not need to be complicated or expensive, trust me . What you are paying for mostly with the average proprietary machine ( I don't mean 1000's for automated) is mostly a little bit of convenience, i bet i could swap my jars out as quick if not quicker than something like these machines you are looking at. -

Good then looks like the plan is a video of tear down and reassembly and lubrication of the ST36. I like the video too because I can show to my family and friends what new crazy hobby I have. -
Great piece of kit. Is that a tin of oats? I see it looks like to be a macgyvered power drill. Nice. How did you control the speed? Don't tell me you hold it while it does all the cleaning cycles? Where did you get that nice mount and stand for the drill? Why was there a need for a step down transformer for 230V to 143V?? Does the hair dryer not get hot enough to melt the shellac on the pallet fork and such? That's a repurposed oven timer right? What's the white appliance? Cool.
