Here I describe the process of making a winder that is both cheap and sturdy.

I tried Grooved Rod, but got mostly normal threaded rods.  Some of them define the threads as grooves.  

There was one called a metering rod but it did not have an empty groove.  Or maybe it has two very thin grooves.  I can't really figure it out.  It might be useful. Here it is:

StopmoNick - you're sport on!! And it was your "tripod centre crank" that got me back on the topic.

Since I came across the cymbal quick-release nut, I can't let it go. I'm sure that I've seen some threaded rod with a guiding groove or a flat side might work as well. And I don't think it was from a tripod. The solution you sketched out has crossed my mind. But I find it raising other issues like stability and friction. Like you, I made one for horizontal use, under and behind the set floor. And I used aluminium profiles as guides, with the threaded rod in the centre, for parallel ease of friction. But this is way too bulky a structure to have on set for most uses.

But I think it's more my lack of English and googling skills that prevent me from finding it. So the question was - how would you describe such a threaded rod? The centre crank for one was not in my library :)

And thanks for the effort of providing such a nice sketch!

Threaded rod with groove?  I don't know if such a thing exists, as an already made object.  The groove is so something can slide along, but not rotate, is that right?

An engineering or machinist shop could probably cut a nice straight groove in a threaded rod for you. 

If I had to make something, I think I would have a plain rod running parallel to the threaded rod.  That would be far away enough so a nut on the threaded rod could turn, pushing something without threads, just a smooth tube.  It would also have a part that reaches the second, smooth rod, to guide it and keep it from turning.

With my track unit, for horizontal movement, the threaded rod rotates, and a nut on it is held by a "claw" shape attached to the dolly, so it does not rotate.  (like an open ended spanner that fits the nut.) As the rod turns, the nut moves along it, and pulls the dolly.   There is also a pair of aluminium tube tracks, one on each side, for the dolly to roll on.  The smooth rod would be something like those, it give it a track to run along. I just did a sketch to make it clearer in my own mind.  Of course, I may have completely misunderstood the purpose of the grooved rod in the first place.

StopmoNick - I've tried to find a 8mm treaded rod with a guiding groove/slid in it. But I can't seem to find one - how would you Google it?

Metalmadcat - I don't think that this puppet will be a part of my contribution to the Halloween stopmo jam. I sincerely hope that some idea will pop up really soon.

It moves really well, I might make one of these!  I usually rely on a rig that has to bend to change the position of the puppet - for heavier puppets, a ball and socket rig, and for light ones, several strands of armature wire.  But this looks easier to control.  Sometimes, if the puppet is flying against green screen with no ground under it, I do the vertical movement with a tripod that has a centre crank, but I could still use the square tube idea for horizontal movement.  The only thing I would add is a pivot close to the puppet, because it needs to rotate around its own centre of gravity, or as close as possible.

Out of curiosity, is there by any chance this puppet going to participate at SJam III? (Stopmo Jam)

Comment by Metalmadcat on May 20, 2021 at 7:25pm

WOW, man. That rig is extremely tight and would provide all types of of ways to work with. Thanks for the insight.

That is a really cool winder. No sprockets and yet it works so well. The research on earlier prototypes seems to've payed off.

If you are going to make one, consider to have a 6x6mm square tube instead of the 4x4 - it will hold considerable more weight!! I'm going to make some further tests on that.
