Model T Ford Forum: Forum 2016: Need some help with broken gauge

Was so lucky to find a matched set of AC ammeter and volt meter for the HCCT I'm building. Then I dropped a tool on the voltmeter and broke the cover window.

Does anyone out there know of a source for pre cut round glass gauge windows? The one that I broke is 2 7/16"

Any good glass shop can cut you one. Beware of their set up fees.

Funny thing is that I cut a lot of glass for my day job, but a circle this small requires a different cutter than I have. Not sure a regular glass shop would have it either.

Mark,
I usually get a picture frame glass, as most gauge glass is thinner than normal stuff--broken picture frame glass is somewhat common too--if you can get it before it's thrown out.
I draw a circle the size I want on a piece of paper, then hand cut with a well-oiled cutter, going slowly. Yes, it's not perfect, but with a belt sander (the narrow ones that sit on a bench top) and being careful, you can get it round enough to go in the gauge and not have the edge show. Since you cut glass, I assume you know to cut parallel lines out from the circle to break of small sections at a time.
And yes, a circle glass cutter like you see them use on TV to get into the house would be nice. . .

Yup. Go to a glass shop. They'll probably cut it and give it to you for free, but throw a $20 into their coffee pot fund.

Check the size of the glass you need with a water well pressure gage. If it is the same you can unscrew the water well pressure gage ring and put the glass in your ammeter. Well pressure gages can be purchased at the big box lumber centers in the plumbing department for a couple of bucks.

I would look for a cheap sacrificial flashlight to donate it's glass.

A good hardware (if one still exists) will carry replacement flashlight lenses in various sizes. They are thin and cheap.

Go to the suppliers page on the front page of this website. Scroll down to RMC INC/Bob Casica. He rebuilds them and has the glass.

Mark,

It sounds like you have an Allen HCCT with the two small Jewell meters. The replacement glass will have to be drilled for the zero adjusting screw.
Send me a PM and I will make one for you.

Might try a clock part house like "time savers"
Or there's other essential they 5 sell round glass bezels and might just search for an old gauge these can be had cheaply

If you dont mind plexiglass, get a thin piece and cut it with a hole saw on a drill press with the center drill bit removed and the plexiglass in a vise.

Joe
