I had a little too much friction in my print or the spring was too weak for extended running so decided to motorize the escapement .
Thanks again NOB21 for a brilliant design and sorry to hack your work. I'll post details on request.
The self tapping screws for assembly of the tourbillion mechanism were all US specification found at a local Ace hardware store. The parts fitting the motorized base to it fit so tight I didn't bother using screws to assemble them. It snapped tight enough together to be handled with some care. I guess once you are satisfied everything is working fine they could be lightly glued or print a long pin with a close fit to stabilize the assembly more but still allow for disassembly.
where did you buy the wood screws?
wood screws M3x16
wood screws M3x8
wood screws M3x40
I printed a single AA battery holder I found on Thingiverse and used Velcro to attach it to the base to make it easier to change batteries. The rest of the wiring should be clear from the photo.
Can you post more pictures of what the inside of the motor box looks like? I am looking for a few more details on how it's wired, type of battery, etc.
Great idea. But you're running a 12V motor on only 1.5V? And would you recommend the 15 rpm motor, if the 30's too fast?
The 30 rpm 12 v motor is one I had on hand and it has lots of torque to run the escapement. However, when I ran it on 12 v it was way too fast. I kept reducing the cell count till I was down to one cell which works fine. A little slower however would I think be better. 15 to 20 RPM would be ideal.
Thanks for your prompt response, George!
I use a single AA battery to power the 12V, 30 RPM motor though a toggle switch. The escapement runs a little fast so you might try a slightly lower RPM motor (you can select the speed motor you want from the Amazon link attached.
HI, I am building one for myself and found the spring not up to the task as well. Can you post some details about your modification? Thanks! - Justin
