What a surprise, I have a weak spot for vibes and always pick up any jazz albums with vibes on them when I'm out digging. So nice to see the inner workings of a vibraphone, thanks!
You will not get an appreciable speed increase by overvoltaging an induction motor. The listed speed is usually the nominal speed, a "tad bit" lower than the synchronous speed, which is 3600 divided by a small whole number (3000 respectively divided for 50Hz countries). Without increasing the frequency of the power supply to the motor, or having an external source of power to spin the shaft faster, you can't exceed or even reach the synchronous speed. The former case could be achieved by a VSD. In the latter case, the motor would act like a generator and backfeed power to the network once synchronous speed is exceeded. The "vibra" part is a misnomer because it is not a vibrato effect, but between a tremolo and LFO controlled resonance. But it sounds nice!
That's really cool. Congratulations on persevering and not letting the motor issues defeat you. I didn't even know a vibraphone had a motor. The instrument sounds great, too. Is it a keeper or will you sell it?
Thank you! Nothing was Jenco specific; I just ordered vibraphone specific paracord, and a few foot long vibraphone damper felt chunk that I cut down to size. The motor I found on ebay by searching the model number of the one I had.
Hi Steven, it was a Bodine Electric Company Model NSP-11R speed reducer motor. 1600 RPM, 115AC. Important: 2.7 Torque, the model will read the same but the torque values change
@@analogemma Hi Emma, how can you figure out the torque on these models? most of them dont have it written. And also, does a 208/240 V makes a difference. I'd really appreciate any guidance you would have into understanding these specs with old motors (especially if you have some recommended literature) Im a fan of your work. Thank you!
@@soultrane9074 Shit I'm sorry they don't give me notifications for these comment replies. I do not know the torque and unfortunately I just sold it to someone haha. I just looked up the model number of the motor on ebay and bought one

I'm glad you enjoyed!!
instant subscribe for being such a sweet person and entertaining presenter. really enjoyed this guide
Thanks so much!!
Beautiful instrument! Nice repair job
Thank you!!
Great work as always. I love anything vibe or fender Rhodes. that bell tone is so nice
Thank you so much!! My dad said it was a giant rhodes lol

Yes
home run, nice work!
Thank you!!
Between this and your lapsteels you could make quite the hawaiian album 🏝️
LOL, I don't have any lapsteels though 😋
Cool project! We'll done.
Kroil and flitz are both top notch products. Semichrome polish is also as good if not better than flitz.
Agreed! Thank you!

Thank you! I think I'm going to make some more videos with it hopefully and then see what to do with it. Not the smallest instrument lol
Such an awesome restoration. Sounds amazing. Where did you get the motor, felt, and string from? I don’t see any Jenco specific stuff out there
Thank you! Nothing was Jenco specific; I just ordered vibraphone specific paracord, and a few foot long vibraphone damper felt chunk that I cut down to size. The motor I found on ebay by searching the model number of the one I had.
Thank you for this! Do you mind sharing where you purchased your replacement belt?
No problem, I got it off Ebay. I looked up "Jenco Vibraphone Belt"
@@analogemma Thank you again! Looks like there are no current listings. Do you mind sharing the approximate circumference of the belt you bought?
@@dapatrick Shit sorry they don't give me second reply notifications. Unfortunately I no longer have the vibraphone
Century Mallet Instrument Company in Chicago.
I have a jenco vibraphone but no motor. Can you tell me the specs of the motor that it came with??
Hi Steven, it was a Bodine Electric Company Model NSP-11R speed reducer motor. 1600 RPM, 115AC. Important: 2.7 Torque, the model will read the same but the torque values change
Okay! And do you know the final RPM after the speed reduction?
