    Default Vintage Mizuho

    I managed to pick up a machine off eBay for $100 in pretty rough shape that I want to fix up for my Dad (story at bottom). I am coming into this completely new so I haven't been able to identify it. Can you guys offer any information.

    Patent Tag:
    PXL_20220720_235908003.jpg

    Story:
    Growing up I needed to know how everything worked and took apart anything I could be alone with for long enough. One victim of this early engineering curiosity was my Dad's vintage pachinko machine when I was all of three years old. Now that I'm older I thought this would be an excellent project for me to work on, get in pretty good condition and get it together as a Christmas gift. I am primarily a woodworker, but I have some electrical training and I think this machine is a pretty good candidate considering it's mechanicals are all in working order and the wiring is still all attached, but shows some amature mistakes that are easily correctable (I may just run all new wiring anyway, but we'll see).

    Appears to be a 1979 Mizuho Seven Dwarfs - VP0075 Front.

    Starting out, I found this YouTube channel informative. There are many how to videos.

    Thank you all for the welcome, and thank you @Bowl987 for the video referral. I've watched a few of Dan's videos, but I had not come across this one. I really appreciate it.

    The play tray is in rough shape on this machine. Is there any realistic way to get a replacement without buying another machine, or should I just look into fabricating my own?

    I have a rough idea that it could look really cool to hand-shape a similar shape out of something I put together from some curly cherry or ask my hardwood dealer to keep an eye out for a good burl.

    If it was a more common brand like Nishijin, you would probably be able to find a replacement, but with this one I'd think you'd probably just have to be super lucky to find one!!


    One person several years ago made a front tray out of wood, but I just can't find the thread.. So wood is definitely an option!!

    If you can supply a better picture of the front tray, I have a Mizuho that I believe has the same tray and is also broken. I don't know if I can compete with a hand carved exotic wood tray, but I would be willing to make finding a resolution such as a repair, or 3D printing a replacement a current project. I have a big chunk missing right in front of the ball discharge. When the winning balls come out they go right over the front edge as soon as the tray gets one layer in it.

    Finally got some time to get some additional pictures together.

    PXL_20220731_180519774.jpg

    Someone definitely tried to "fix" it with some sugar, or something similar.

    Two other things I've found are the weight arm for the ball-out light contact:

    and the feeder tray:

    Finally, there appears to be a spring missing here that I can't identify:

    I figured out that the last picture is just the front drain trigger, and was not missing a spring after all.

    Ok. So the front tray will be the big thing of course. The upper rear tray can be patched and I'll post some info on that soon.
    The low ball ramp is no problem, I just created a Sankyo version a couple weeks ago, and I have a counterweight solution I'll post also.

    I have a Mizuho that I fixed up about 2 years ago. As you have already pointed out the last picture is the ball drain and is powered by a spring under the track. I also took a picture of the counter weight for the ball out light for your referece.

    On the rear upper tray, flex the plastic in the broken corner enough to spread it open and see if you can match up the broken edges some. It looks like it is only a small hole that needs to be patched.
    If you are able to get them to line up nicely, the next step would be to flex it again just enough to put some superglue in the cracks. Then clamp it together with cloths pins or something and let it sit for an hour or so to make sure everything solidifies properly. Superglue used in abundance takes a lot longer to set.

    I actually have a small DLP 3D printer so i may just use some of the UV-reactive resin and a UV flashlight to make the plastic bond. I may be able to make small layers to plug that hole in the same way as well.

    I'll post my attempt either way.

    Oh! I have that spring! I was actually looking for where it was supposed to go, thank you.

    I use styrene plastic to make patches on trays as I have it already on hand, and it's soft enough to bend around curves with just a little heat and super glue works well with the original ABS and the styrene. I guess I should post the how-to thread like I've been promising to do.
