Thinnest I can get is 2mm Dave. Should be OK to cut. A bit easier than 3mm

Keith, The 4 bolts flanges look like table "E" flanges but what are the 3 bolt flanges, please... The boiler front looks tops, well done...Cheers, Peter

There is thinner available but as the thickness isn't really seen once mounted 2mm will work perfectly and is far cheaper than 1.3mm

Also I have 2mm that I didn't use on the carriage

Three bolt flange is my design - Four bolts on the 20mm OD flange just wouldn't work. Not enough space for the hole spacings

Hi All,

Been a bit crook, my son decided to share a bacterial flu with me - on antibiotics. Anyway - can't get in the way of work on the Stirling.

I have made up the boiler water sight glass. This was an enjoyable part of the build. Lots of machining and getting parts to fit together. I worked out that there are 21 machined up components I had to do to get this assembly together. The majority of parts are machined out of aluminium on the lathe.
My glass cutting went OK. The glass on the sight glass is 10 mm wide X 32mm long - 4 pieces. The trick on glass cutting - only one score line and then crack it off.
I masked up the glass and then sprayed with primer. The second coat was "Super Gold". Happy with that outcome.

Painted the firewall in "Domino" and then painted the valve and handle I made the other day.

Next on the agenda is another valve.

Regards

Keith

Gauge glass looks authentic.

As a locomotive fireman/boiler attendant the only thing I would do is change the steamway cock handle from pointing up to pointing down.
What difference does it make you might ask?
While the handle is in line with the glass the cock is open, however with vibration of the engine the cock handle might move (and with a bit of help from gravity) to a position where the cock is part of fully shut, and then you would have a false reading in the glass. If the handle is already in the down position, as is the waterway cock and the blowthrough cock, it is unlikely to move.
I should also add that with the handle in line with the glass the waterway and steamway cocks are open and the blowthrough cock is closed. This is contrary to normal practice of cock handles.

That's beautiful work. The gold really pops! I thought it was brass.

Thanks Kevin,

I put all the cock handles in the exact position they were on the photo I had of the Stirling ???

The Super Gold works really well - but you need to be careful not to touch it for a few days (unless wearing cotton gloves) as touching with the skin "tarnishes" the finished job.
