The Diary of the Building of a 5" gauge Stirling Single

    

Completion of the build     Part 11
18th August 2019

Made up an order for parts and emailed to Polly Engineering

19th August 2019

Paid for order to Polly Engineering and then continued with more pipework to the on/off valves for the injectors.

As you can see a set of wheels had to be removed to access the area and tighten the nuts.

I need more 3/16" copper pipe !!!!
20th August 2019

Went to our local engineering suppliers and bought more 3/16" copper tube and some suitable nipples.
21st August 2019

More pipework installed to feed the two injectors and the tender pump to the loco.

As I needed to shorten one pipe as I put the bend in the wrong place hence the use of the straight pipe to pipe link.

The tender pump is a HIGH PRESSURE feed the others are gravity meaning that I need to use a pressure connector for the Tender Pump link.

Until I can couple up the tender to the loco I cannot assess the amount of rubber tubing needed so until then I will press on with the BYPASS from the Axle pump and the feed to the Axle Pump.

Started work on the coal arrestor to stop coal falling out from the coal storage area in the tender. Brass plate cut to allow water to find a way out if it went over the coal, Then sand blasted and then give a sprayed coat of etch primer ready to paint black tomorrow .

The picture was taken on the 25 August 2019, it is not dameages that is reflection - sorry !

24th August 2019

Coal arrester painted Black and work done on the Loco transporter to take loco from storage bay to back of car.
25th August 2019

Securing down straps ordered and should be here tomorrow. The idea for the straps came from Paul an engineering friend who gave me one but I needed more.

The one from Paul has been shortened to hold the loco steady on the lifting unit shown above.
The coal arrester is not fitted and also I have put the tender to loco connector in place and the four 2BA bolts holding the tender in place which as bras now have brass nuts too !


The picture was taken on the 25 August 2019, it is not damage that is reflection - sorry !

It took 2 hours to make this little piece which is part of the reverser system. What with drilling the two 1/16" holes and then milling the slot and finally giving is a bit if shape with hack saw, a Dremel cutting disc  and also a file.
27th August 2019

A day spent helping with the local Engineering club activity days and discussing brick arches and exhaust variation.

In model engineering the "brick Arch" is made in Stainless steel .
28th August 2019

The reverser controls were completed ready to cut the grooves in the radius.

I decided to extend the arm as in the original drawings it was too short and gave me not enough room. So a piece of steel was silver soldered in filed to shape and fit and then assembled the parts.

The spring is over sized but all that I have at the moment.
29th August 2019

So after another 3 hours work on the reverser it is ready to apply Air to the cylinders.

This proved that all was well and I can proceed further.
30th August 2019

A major milestone today I was able to rebuild, with a lot of help from a friend we was an engineer on ship during his working life, the regulator and fit the super heaters.

The super heaters which had been modified by a friend in the Club did not readily fit so the joiners had to be modified with and angle grinder until they did, and then pressure tested which found a very small leak which was rectified by re-silver soldering.

The operating lever in the closed position. It had to be bent up to miss the blower connection and the stop had to be filed a little to allow the correct travel.
Regulator hand in the open position.
The valve in the open position.
The regulator valve in the closed position.

A gasket material has been used with gasket sealant each side.
The valve cover was installed using the paper gasket and some gasket sealant.

I can now progress to installing the boiler on the chassis.
