Interested to see how you dealt with this one!

Haven't done anything yet; too much spring yard work plus repairs to my recently-acquired electric steeplecab locomotives (7.25" gauge: a bit big for this forum).

I'll be sure to get back to you all when I either succeed or fail.

Well that's a poor design for replacement... Did you figure anything out with this one?

Thanks, Stoker and Dennis, for your suggestions. The silicon should work nicely.

Of course I can drill a hole! I can either tap the material if it's thick enough or drill both parts and add a hollow carrier threaded externally on both ends; just need a pretty slim gauge glass for this. I'll work it out, and can't do worse than ruin what already doesn't work....

As above. high Temperature silicon
But I would not use JB weld or similar.
Other option but more work would be drill a hole in one socket ,top or bottom then thread a cap onto it .
 And slide glass down but Probally still need high temp silicon.

Cheers
Dennis

With a setup like that I think I'd consider glueing it in with a high temp silicone sealant or possibly even JB Weld.

Got this Harvey Miller Watt Jr. engine last summer. There's not a lot wrong with it now that it's un-stuck, but the gauge glass is missing and I can't see how to replace it short of scrapping the original mounts and substituting a modern assembly.

I'd prefer to keep this original if I can.

Sorry about the poor pictures. I thought I had better ones. Tomorrow I'll see if I can take some more so you can see how the gauge glass was originally fitted.
