Yoke Proto-Type Pictures (More Pics added)
Xiaou2:
good to hear that theres angled arms now.
Some things youve got there make a little concern tho...
You only have 1" or less ? (hard to tell by pics) From the control arms
to the base mount. So basically, if you mounted this on a control panel, and pushed the arms forward, they wouldnt travel more than 1cm - then would smack into the panel.
The cover shape is a bit odd. Im suprised that the small box will fit the innards. Again a proto with no inner pics?
Another concern is the gear ratio. From memmory I think the starwars controller main gear is like 2" in diameter....and had many more teeth per inch than what I see here.
With a smaller drive gear... your aiming will be less precise... because of a lower resolution.
I realize its not easy to find the correct gears in quantity.... but then again, if someone is going to pay big bucks for the thing, they surely are going to want primo control.
No show of how the springs are mounted also is concern.
Atari made '4wd' type wheel and its poor design lead to the springs eating the metal holder and they would stop working. This process took about 1month of arcade use.. then had to reorder the spring holders and rebuild them all over again.
Obviously, you do not have the springs to show... so I cant fault you there.
All in all, in not bashing your product - just trying to make sure its the best it can be. Better to get all the bugs out than sell them and have them returned + bad rep + having to go back and redo them later.
Edit:
Took a peek at the diagrams in the starwars manual on klov. Seems they used a rubber bumper system (4 bumpers) to keep the yoke from turning too far left or right... and to take the abuse away from the yoke itself when slammed hard. I do not see that on your design.
I can not decypher how they stopped the handle movments tho - as the diagram is a bit hard to see that detail.

Looks like it to me as well.

The only thing one needs to be concerned with is ratio, provided there is no "slop" in the gears. As long as the gear ratio is identical to the original, the number of teeth is irrelevant.
In other words, if turning the yoke 40 degrees yielded an 80 degree turn at the pot, how you get it to do that isn't as important as just getting it done.

Tailgunner:
It's cool to finally see the prototype. I'll agree that the pics make it look like the grips will be really close to the control panel. If that ends up being the case a 3/4" spacer made to fit between the mounting plate and the control panel would solve any clearance issues.
No idea on the springs yet, but the original Atari yoke's spring setup is less than ideal. It works, but in doing so it chews up the post the springs act against. As far as the grip shaft in the originals, there's a 3/8" solid bar in the center that acts as both the bump stop and the post the springs act against.
Looking at the pictures pointed out something to me that I hadn't thought of before. If someone had a set of original grips from a parts yoke, it'd be quite easy to make adapters to fit them to the Gamecab yoke.

Hey Charlie, great to see this coming together!

(I know, I helped a little on this design :) ) Also, the Star Wars enclosure had a LOT of empty space (about 1/2 of it was unused) so I don't think this is a problem. A gear, a pot, a spring, how much bulk do you really need to house that?

True, but then that extra depth helped to get the grips away from the CP.

They were on the first Gamecab yoke, and they worked just fine.

That's possible, then again it might just be an optical illusion caused by the picture. Excepting the first pic the grips don't look angled to me, while I can vouch that the grip mounts have the exact angle as original Atari grips. ;)
