The beveled glass lens in the antique barometer was cracked. The tolerances are very tight fitting the glass in the brass bezel. The glass is friction fit . It is not glued in .
The old glass was repaired so it could be use to cast a high temperature mold . The mold and an old piece of glass went into a kiln to form a glass blank.
The blank was cut to size , beveled and the dimple was ground and polished. The dimple is use to add additional clearance for the center stem.
I hope to update the post with a picture of the restored clock. I have made many lens for old clocks but this is the first one with a additional polished bent and dimple.
A clock shop sent me the front and back bezels from an antique clock. They needed the beveled glass replaced. I used vintage glass. It is very important to use antique glass when restoring a clock. Using new glass will greatly effect the value of an antique clock.
The bezels look round but very rarely are . I have and use old glass from the period the clock was made. The equipment I use to bevel the glass is all so period. Most of my machines I use are as old if not older than the the clocks. The machines are run by leather belts and use lead babit bearings. The beveling and polishing equipment are power by electric motors not steam engines as originally.
Note the small pitts in the glass .
The beveled glass lenses are made to very tight tolerances and are install in the bezel . They are not glued in.
The clock on grandmas mantel fell and broke . It was a basket case and I had no idea how many pieces were missing. I started the reassembly and hoped for the best.
I told the customer I would do my best but it look like there were a lot of pieces missing.
Filling in were needed for missing pieces.
I have repaired many types of glass clocks most of them crystal. This was my first antique amber glass mantel clock. I have made many kinds of custom beveled and custom bent glass for clocks. Clock shops send the bezels to me to install new glass. I use old glass when necessary to maintain the value of the antique clock.
The antique clock sat on the mantel since the beginning of time . One of the kids went to wind the clock and broke the glass . I save old glass for clocks like this. New glass is a different color green and is very flat. The antique glass has a yellow hue and a distorted finish. Sometimes the antique glass has bubbles and blisters . This is important when it comes to the value of the clock. An antique clock with new glass doesn’t retain its resale price.
I have antique beveling machines that run on leather belts. The same type used to make this antique beveled glass lens originally. The fitting of the antique replacement beveled glass in the bezel is very tricky. The tolerances are with in thousands of an inch. I make replacement beveled clock glass for clock shops all over the the country most of them in New York and LA.
The lamp fell and two pieces of beveled glass were broken. The front lens was a diameter and I used a piece of old mirror because of the color. The newer glass has a very dark green color to the edge. The antique glass has a yellow not the green edge. I have repaired many Rail Road lights over the years. I used cast iron grinding mill to rough in the bevel.
I cut the antique glass and rough in the bevel.
Hand beveled replacement glass
Out door light with four broken curved beveled glass pieces . The hard part is the metal it got bent when the large piece of ice fell and hit the light. First with a hammer and a piece of wood I repair the metal . On to the glass I made a mold and bent 1/4 inch glass to the pattern needed .Test fit each piece then hand beveled each glass panel. Installed the new beveled bent glass panels and gave the light a bath.

Old old clock came to me from a clock shop . It needed a beveled glass installed in the brass bezel. This is a tricky job because clock bezels are not round so the bevel is hand made to fit the out of round bezel. Its very easy to chip the new beveled glass during the installation .
