So i bought a new motometer for a discount knowing one of the face plate/rings didn't fit quite right. You couldn't get the 4th screw in. Well I got the screw in and thought all was well and good. Well, i got it out and found one of the face glass pieces broken. Now, I had to put some pressure on the screws to get them in. So it must have snapped in storage. Does anyone have any ideas on how to repair this? Im more concerned about the actual motometer itself than the glass. I know you can get replacement glass pieces, but if the fault is in the actual meter then it wont do much good to get a new piece only to break it again.
i have not fiddled with it since i got it out. When i get a chance id like to take the glass piece out and see if it tightens up without the glass in to see if the glass piece was oversized or something.
When i put it together to 'fix' it, it seemed that the screws were too short and did not want to bite into the threads enough to hold.
So im thinking its either;
Maybe the face ring is too 'dished'
the countersinks in the dished face arent deep enough.
The glass may he too thick
The screws or the holes in the motometer 'frame' are stripped or both.
Or the glass is too thick.
Anyone have any ideas?

Looks to be a reproduction. Check with Restoration Supply Co. They may have the glass and gaskets that go under the glass. Or you could buy another non working one and barrow the parts from it.

Yes, its a reproduction.

Just a thought, no idea if its a good one for this need. Watchmakers who work on old stuff may have a machine that is used to precision grind a new crystal to fit it to the bezel of a pocket watch.

Restoration Stuff.com has the repair kit you need for that jr size repro Motometer. 2 bevel glass lens 2 die cut gaskets, and 8 stainless screws.
Part No. ACC069. $17.00. The other kit with brass screws is $3 extra

Appears your repro was re-worked to use an original midget black face dial, have done several and some need a bit of finesse to fit the old plates to the new Motormeter, and most times use the original screws off an original Motometer or the new screws if you are using the original Motormeter rims. The repro rims are different.

Thank you very much!
I was looking at the Moto meter on our 1925 touring and the the face rims looked a little different than the one on my brass reproduction motometer.
I appreciate the information, and the tips with the pictures!
