Hi Christophe, Its hard to keep up with you :O)

[wizard69]

Well done! Just goes to show there is always a fresh approach to an age old problem.

You certainly deserve it. This is an approach I never thought of even in my more wild dreams. This is somewhat like a linear actuator we use in automation except that you put the human in the loop, very impressive way to do something fresh.

That is the coolest human stepper motor I have ever seen
This has to be the coolest semiautomatic fingerjoint jig out there. Good job

[Paul Alciatore]

That looks very clever and it seems to work perfectly. Great job.

One detail that I did not see explained is the encoder disk you used for the optical sensors. You might say some things about how you arrived at the number of holes that you used and how you located and drilled the holes. I would think that any roughness or fuzz on the edges of the holes may make the readings erratic. Did you have any trouble with that? Did you do anything special to clean them up?

I know this is a wood project, but I would have been tempted to make that disk from metal (aluminum) or plastic.

Congratulations Christophe.

Quite impressive work. Tailor made to the small size of your shop was a challenge you've overcome in spades. RR.
