Atari Yolk 14 tooth gear Repoductions

I will be happy to continue to provide updates in the future, but I have somewhere between 40-50 games on each of Randy's gears. I pulled and photographed them again.

You can see the slight discoloration I was talking about on the fully printed gear. I was very ginger about the set screw only finger tip snugging it down as I did anticipate that it could be a problem without a threaded insert or anything. I don't think it is a problem since I would much more highly recommend the half-printed version anyway. That's the one that I put back in my yoke.

Attached photos are in the same order as before and I added a broken factory one because it was on the bench next to me.
A: Fully 3D printed from a different vendor
B: Randy's fully printed version
C: Randy's half-printed version
D: Repro of the original (from them that shall not be named)
E: Original broken gear

RandyT:

The fully printed one is definitely getting stress from the set screw.  I wasn't kind to this part when I made it, attempting to thread the screw into it directly, before deciding to use a tap.  Could have introduced some "slop" and made the hole too loose and/or compromised the structure.  Either of these would allow the set screw to act like a lever.

Honestly, the way the fully printed one is done here, was not my preferred approach.  As I mentioned to Chad, I think the better approach would be to make the collar portion to be in  the same "D" shape as the shaft, which would better distribute the forces to the collar, rather than directly onto the section around the set screw.  Unfortunately, I don't have one of the pots here to use as a reference/gauge.  The size of the set screw was probably too large as well, reducing the size of the plastic area, but it's all I had on the shelf.

If I can get one of the pots in here, or determine whether it is an industry standard shape so a substitute could be employed, I'll give the fully printed version another go.  I still think the replacement gear on the original hub is the best approach, but it may not be an option for some.  Thanks for the photo documentation! It's very helpful.

Honestly, I wouldn't hesitate if I were you. Us KLOV'rs can be tools just like some of the contributors over here, but everyone is still looking for workable replacement parts.

I wouldn't hesitate either. The other guy who started 3D printing some of these gears wasn't a klov'er at first (I think a friend posted for him) but subsequently joined klov to post about his stuff. I don't think anyone had any issues with that. If you limit your posts to reproduction parts and don't bump your threads I think you'll be fine. I don't come to these forums much anymore so if I didn't happen to stumble across this thread I'd have never known probably. In that case, I would've been glad to see you post a product announcement for this over there.

Any ETA on putting these in your web store?
