Nisonger Instruments Mamaroneck , NY

I need to alert my fellow British car owners about a very disappointing experience I had with Nisonger Intruments in Mamaroneck, NY.
I sent my Smiths gauges to Nisonger for repair.
All my gauges were functioning normally but needed a cosmetic overhaul. Two of the gauges were returned to me with less than desirable results. The oil pressure gauge was not accurately functioning and the Kienzle clock had a cracked lens. I sent them back to Nisonger under their one year guarantee. The oil pressure gauge was again sent back to me not functioning correctly. The clock was not functioning at all. Despite being under a year Guarantee I was charged $35 dollars by Nisonger for some bench testing service charge. I called Nisonger and spoke with Peter Bayer. I pointed out these problems and that my gauges were under a year guarantee. He did not want to take any responsibility for anything that happened at Nisonger. He also addressed me in a condescending manner.
I sent these gauges to be repaired at my expense at a reliable company. They were able to repair the oil gauge but told me that the Kienzle clock was not repairable.
Nisonger also tried to charge me $30 dollars for some unneeded bulb boots.
There are are other choices when it comes to gauge repair. I hope that relaying my my bad experience with Nisonger and Peter Bayer will caution you using this this company.

I know we generally avoid negative vendor reviews on the Forum so I won’t comment on DrD’s experience other than to say if anyone is unconvinced I will be happy to PM my experience with the Boys in the Bronx and Peter B.

I would like to hear of a demonstrated good instrument rebuilder as the main odometer on my car has failed.

Les,

Call Morris Mintz and ask him if he can help

Much appreciated John!

Can they re calibrate a Speedo just by telling them the difference?

Generally they have you measure the number of turns of the speedo cable when the car is rolled 1/100 of a mile (52’ 9.6"). Pretty easy to set-up and take several readings to assure a reliable number.

I’ll second the recommendation for Morris Mintz at West Valley Instruments. He’s modified my Tach to work with a 123 electronic distributor and it’s perfect; modified my clock to use an outside AA battery and it’s perfect and recently recalibrated my speedo. Great work and quick turnaround at a fair price.

I used to use Nisonger but had some unfortunate experiences.

I know but annoying
I can’t believe someone doesn’t has a set calculation from 288 to 307 or 353

I suspect there are just too many variables to be assured of a good result every time, including tire size, tire brand, tire wear.

I don’t know about recalibration, but I had a speedometer shop in Denver make up a gear box that they spliced into my speedometer cable that corrected the speedometer to read correctly when I changed from a 3.54 diff to a 3.058. I provided them with the old and new differential ratios and my speedometer cable, marked where I wanted the gear box spliced in. They cut the cable and put on the correct fittings to connect to their gear box. That box is about the size of a pack of Camels and sits above the transmission. My speedometer reads accurately.

Just had my combo oil/temp gauge rebuilt by Nisonger, they did a very nice job, however their turnaround time was 6 weeks or better [ actually took 7.5 weeks, ] and took 9weeks from my home and back, very slow service.
I have just sent my spare combo gauge to West Valley and they report a two week turnaround, comparison quality of repair is yet to be noted.

Someone here recommended West Valley Instruments a few years back so I had them do my gauges as well. My experience with them was uneventful. Price to do all gauges on my '50 '120 was approximately $1750 in 2018. Turnaround was about 90 days. They look and function great. At the outset and upon receipt of your gauges, they’ll ask you whether you want them to be made functional to full blown restoration. As mine had a lot of flaking paint, a frozen tach, non-functional fuel gauge, frozen odometer wheels etc., I told them to do a full blown restoration on all. Making everything functional again doesn’t take them long as they say they have all parts needed in house – it’s what they call “the art work” (repainting the dial faces, needles, lettering, etc.) that sucks up the time – some of which they have to subcontract out.

Ditto. Yes, a bit slow, but we’re in the middle of the pandemic. Perfect work, I am very pleased with the result.

West Valley have now just mailed my combo gauge , with a 4 day turnaround.
Now that’s service. Calif have a pandemic and fires.
