Hi all, I just picked up a W?D and like many, the slot reel hubs are cracked. I am working on having some replacements made from new Acrylic (AKA Plexi-glass). If they work out on my machine I can have more sets made, just wondering how much interest there would be out there in community for a part like this.

OK everyone, thanks for the interest. I am probably about 1 month out from having the prototypes done, I'll post some pics after I get them mocked up.

Just a quick update, parts are designed and the prototype run of 6 reels is on order. It will be a 3-piece design, center hub made of aluminum to attach to the motor via set-screw, Plexi hub and Plexi tub.

Does anyone know if the opto-sensor can see through the plexi, or is the "notch" in the original required for it to function properly?

Should have pics in 3-4 weeks with my current work schedule.

I guess I am just questioning if the label is enough to trip the opto or if I will need to notch the plexiglass. I will do some experimenting with masking tape. I have 2 weeks before I get the center hubs.

A couple in process teasers . Still waiting on the aluminum center hub to attach to the motor
The wheels are about 1/8" wider so the decal won't be "over" the hub area. Going to have to do a really good job securing the wires so they don't interfere.DSC07434.JPGDSC07435.JPG

Also for anyone repairing the slot machine; if the decals are installed properly the numbers in the corners get covered up, here is a picture of the proper wheel order based on the seams being aligned.DSC07440.JPG

Since I don't have the hub yet I can't attach and perform the trial.

Update pictures, the thinnest acrylic tube I could get was 1/8" wall and it doesn't fit through the opto-switch. I will be turning down the inner diameter as soon as I can get some open time on the lathe at work, probably a week or so for the next trial.

I finished up the set yesterday, just got them installed tonight, but they aren't working properly yet. Since I was afraid to waste a set of decals I just coped them onto standard paper and used some packaging tape to put them on. With this set-up, the opto trips like crazy in the test menu; and just spins forever on a slot spin. Going to have to try to cut the notches out and maybe try some masking tape instead of packaging tape to see if it can block the opto-switch better.

Update: The opto-switch was reading through the paper in some areas; used some painters tape for the 1/4" that passes through the opto-switch. Got the first set working 95%. The center wheel lines up on the line 100% of the time, but the other wheels go slightly past center and the symbol is correct, but just past the center line. I'll get some more pics over the next couple of weeks.

@Methos - I am going to try another copy of the decals to ensure I aligned the notches perfectly, next I am going to try swapping motors to see if maybe they need to be replaced. Judging by the wire colors on the middle motor it is newer, or at least different. I am leaning towards it being the motors because each symbol seems to repeat it's location, but they aren't all equally below the line; if that makes sense.

I am getting very close, but with how much machining is required on the plastic they won't be cheap to make.

After some trial and error I have successfully made a full set of wheels! Slot is matching the DMD 100%, Wheels 1 & 2 line up perfect, Wheel three is slightly off, like maybe 1/8" away from being on the line. While I was at it I replaced all three motors per this post: https://pinside.com/pinball/forum/topic/15-who-dunnit-and-scared-stiff-motors worked out great. I still only have a "copy" of the decals installed with packaging tape over the wheels; looks good enough that I may just leave it. I will have to get some video this week.

Got a set done and functioning 100%!!!

In order to get the optos to read the slot properly I had two options, a darker color, or use the replacement decals I ordered. The replacement decals don't compare to the originals - it really shows on the extra ball.

I also had to slot the optos a little in order to get the wheels to fit properly.

So I photoshopped the background to purple, printed it on gloss paper, and used packaging tape to attach to the wheels, I think they turned out great.DSC07455.JPG

I've got one extra set of these available for $90 + shipping. Send me a message.
