I have been pedal hunting for a few weeks now and have some advise. Could be good advise as well:)

1) Don’t purchase a variable speed pedal from amazon that is from china and claims to be variable. This one looks ok but has only 5 speeds that are set by 5 large bar resistors. Not good for lathe applications.

2) The next pedal is fairly inexpensive (38 bucks) and may work for some, however, i found that all my motors jittered when running. This pedal is based on a small part that controls the speed through either Pulse Code Modulation or some other algorithm that drops the current. This part is the exact one used in hand drills, etc. I think the Company is good and responsive, just think that this component of the foot pedal is low end. I also think the plunger will degrade quickly with constant use. Part is from a Japanese controller company.

3) Sewing machine pedal. This is great if you use a sewing machine AC motor. Need to ti make sure that there was not another controller within the sewing machine between the pedal and the motor.

 

4) BEST Controller is the Lucas #9 Lowboy. This controller is a high quality build all metal with a low pedal that will not strain your foot. Not sure what the electronics are, but it has great linear control and feels like butter. The cost is only $50 bucks US ($100 canadian for me with $25 shipping). A great deal for the quality of the build.8d9aa7aa3c0b8e6e4471865e4c1c341c.jpg

Update on the world of foot controllers. Turns out that the electronics in the lowboy are the same as in the Foredom pedal. On the sewing machine motors, they both work ok but do have a little PCM jitter. The router speed controller i have is smooth and has a circuit board with a knob rheostat. This is not a pedal but works extremely well if you want constant speed.17cf6be4c86fe7f057c64cb647d289e0.jpg
So i must apologize to the Foredom folks as they all seem to use the same plunger Japan component in the foot pedals. I will now investigate smoothing out the power signal to the motors after the foot controller.

      Elgin Grade 315: Runs/stops with dial down/up

      Ok. So given that I had free oscillations DU/DD for roughly the same time, I reassembled with the pallet fork and bridge underneath, and now I can see two more problems.    1. The arms of the balance are nearly flush with the pallet bridge. Bad. I can speculate as to why…the end shake still looks to be too much. Maybe other causes as well? 2. The balance doesn’t spin freely. In the resting position, it looks like the impulse jewel is outside the jaws of the pallet fork. Not by much, but still outside. If it needs be inside in the static position, then I’m guessing I’ll need to rotate my hairspring collet to change orientation by a few degrees.    The journey continues…

      Somewhat as reward

      Hi. I have been touching watches for quite some years, but haven’t before pretty recently decided to jump of the cliff by trying to do basic service for the first time. It is a simple Seiko 6602 I bought as a renovation movement.  To be honest I struggled. Mainly because I wanted to do everything correctly and with all the right tools etc from the start.  From just having basic tools I invested in quite a lot of things in order to dissemble, clean and lubricate the movement parts. I can say it was a journey.  Taking care of the balance jewels looks really easy watching all the great videos, but god damn… I have been lucky and only shot away things that was found but come on. Anyway. I have now managed to “service” four movements and the result is what makes me want to keep doing this.    The first movement was a Seiko 6602 and it was in a pretty bad shape. When I run it on the Timegraoher now I got an amplitude of 270 and in all positions it stays around +-2s.    I have heard some “amateurs” saying this is a hobby you’ll get stuck to and I am already there. It doesn’t matter if it’s a fancy movement or a simple 6602. The feeling after been struggling and you see the result… it’s amazing! I am still in a state where I am confused and don’t know which watch press tool is best, or if I need the most fancy hand tools etc, but to be honest. This is so stimulating.    Sorry for not really adding anything new to you all pros.

      Casio normally put the movement number of the case back. Edit So it's a 709 Module (as Casio call then) you're looking for.
