Serving tool

Small update
The alligator clamps are not always perfect to use. They sometimes loose grip on the subject. Something you don't want working on your rope.
So I made new ones, I used wood. Not normal wood, something (I think Ipe) very hard and old. you can't scratch it or put a hole whit a center point in it. Perfect as clamp. See the pictures, if you have questions I hear.

Nice bit of development Stephan,

Cheers,
Stephen.
 
Hello Stephan, that is a very interesting thread, particularly because I am embarking on a similar route.
It appears that the pitch of the serving thread on the parent rope depends on the ratio of the gears between the driving rod and the rope turning mechanism. And the ideal pitch of the serving thread will be dependent upon the diameter of the serving thread. Yes?
On your machine the only method of altering the pitch of the serving thread would be to alter the ratio between the two gears?
If you alter the diameter of the serving thread you will need to change the gear ratios. At least, that is the way it seems to me.

I am designing a serving machine which will alter the pitch of the serving thread in the same way as in making a metal working thread on a CNC lathe. Waiting on parts to arrive before assembling my machine. Will post when I have something to show.

Thanks for visiting my log John. No the pitch of the rod have noting to do with serving. You can also use a unthreaded rod for this. Because it's the yarn that turns around the rope and the tension will make it push forwards at every turn. The small hole in the spoolholder is the clue in this. It avonds that the rope makes double turns. Slow speed is better then high speed.

My bad. OK, so the serving thread being wound onto the rope determines the pitch. Does it ever create gaps or double up?

Yes, that's why there is a speed control on the engine and a adjustment on the sewing machine spool. And wobbling of the spool is another cause. That's why in the middle I made that support. I think the best thing to use is a brass tube for that. A tube is stronger and less flexible.

My serving tool is ready and working precise, fast and is automatic.

See the pictures and movie.

Most parts come from Ali express and the motor and power supply are scratch from an old Canon pixma printer.
On Ali I got a direction unit for 3 euro, left turn or right turn just by pushing the button, even the speed is adjusted.
Most parts are cnc parts
If there are questions let me hear.

In post #13 you find an exact description and part list to make one on your own.

I think you enjoyed making the machine as much as making a model. Nice, accurate manufacture. Well done.

Thanks, yes your right. I love to make things with my hands. Making a ship is fun but design and making such tools is fun too.
