Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
Contact them before ordering. Most if not all replacement parts available new (other than face plates) are for the Junior size. I used a brass plumbing fitting for mine, then poured the cap base full of epoxy.

I made the brass nut for my mm on my screw lathe.

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
Wonton,
Are they a common diameter & thread pitch? I had a BIG "Universal" MOTO-METER on Minerva & it already had 2 nuts on it I just cleaned it up & it worked PERFECT At swap meets, just test them with a BIC lighter. If the RED separates on the car, cover part of the radiator, when the red connects to the upper RED, it'll be like new! TIP#181: If it cycles UP & DOWN regularly every 2 minutes or so, while cruising steady, YOU'RE LOW ON WATER!!!! Bill W.

do you have a thread gauge you could figure out what size they are? im sure someone in the vast internet someone has some. or if we have a size and a thread pitch we could look in our assorted coffee cans of stuff.

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
They are not a very common thread size. The nuts from Snyders etc will not work. I have been down that road. The tap I got for doing these is a 7/16 27 NS thread. I bought some brass nuts that were large enough but had small threaded holes then drilled and tapped for the JR Motometer I had.

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
John Duden,
If nobody comes up with the correct size for the original Junior Moto-Meter nut. I'll take one off of one of my display meters and mail it to you. I would like to have at least three more extra correct size nuts. Bob-A |

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
Sounds like a straight pipe thread.

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
7/16-27 was an old gas lighting fixture thread size.

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
I just measured mine with a thread gauge. It's 7/16X 20, the same as a head nut. In fact I was able to screw and old head nut down about four turns. If yours is the same as mine, Try lowes or Home depot. Use stainless if brass is unavailable.

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
The thread on an ORIGINAL Jr Boyce Moto-meter is 7/16 27. Someone in the past may have "cleaned" up the threads.

Re: Boyce MotoMeter Mounting Nuts & Fine Screw Threads
Mac's lists a Motometer nut, but just from the picture it looks like coarse threads. I did a Google search for 7/16-27-zilch. Can you just redo the threads on a different nut?-kind of patchwork. John Duden may be your best bet.
