Thanks, it encourages me to keep posting the pics of the journey of this loco build.

As the late Douglas Adams said,

The chances of finding out what’s really going on in the universe are so remote, the only thing to do is hang the sense of it and keep yourself occupied

while I mention Mr Adams, I like this one as well

There is a theory which states that if ever anyone discovers exactly what the Universe is for and why it is here, it will instantly disappear and be replaced by something even more bizarre and inexplicable. There is another theory which states that this has already happened.

Working up my boiler drawings to take to Mr Inspector. The usual 3D then to 2D working drawings.
I am blind in one eye and I cannot see out the other, but going over the AMBSC Cade Part 3 Issue 2.00- 2017 Sub- Miniature Boilers ,
I cannot find a mention at all about barrel wall thickness. Only part 2.3.2 which mentions Max diameter 63.50m . No mention of wall thickness to comply with. :scratch:

I will be using 1.60mm wall, 50.80mm diameter. The original drawing which was in the May/June Issue of Australian Model Engineering has a barrel wall of 1.20mm.

Tim, the next installment should be the final erection of the locos motion by the Llewellyn Workshop crew, and said with apprehension, testing on air.

Eccentric rods are on, and all goes around, a wee tight, set the valves, all seems to be in order, the covers to go on tonight.

That's really impressive. I wish I'd learned more workshop skills in my life. Too late now to teach an old dog new tricks.

I'm also looking forward to seeing it run on air.

I hope it moves. I am genuinely apprehensive. :| So far, it all is going together OK, I did pay a lot of attention to accuracy so I hope that has a pay off. I am not trying to rush this stage.
I used Loctite Flange goo for the chest to cylinder and the back cover, but to give easy pull down if required I am intending to use the good old oiled brown paper for the steam chest cover and front cylinder cover.
I hope it all pays off. It might be Kero lube for a while as it gets a good running in.

You can’t go wrong with the old oiled brown paper though. :thumbright:

Looks very tidy so far, now fingers crossed for pressured air testing!! :thumbright: :thumbright:

Yesterday I took the afternoon off and caught the Sparky into town and attended a presentation of the "Sydney Mail" by Queensland Rails rail historian Greg Hallam. Met up with friends and after we paused at a cafe to tell stories where I noticed the brown paper bags for placing slices of desert into. I requested one paper bag along with my cup of tea, tossed some extra coin into the tip jar. After dinner, in the Red Room the paper bags use is realised. It was .06mm thick when dry. Print off the steam chest over and front cylinder covers in 1-1 scale. Some cello tape. Line up one of the previously made shim punches in the little mill Drill. (1.70mm for the 10 BA, 1.75mm would be better if I was into production mode) . Pressed some holes, then out with the sharp pointed scalpel. An oil soak and then fitted up the chest covers. It was fun.

Yes, I can see it..... no I can't. Fun must come in a variety of ways and that isn't one. However, if it works for you then that's fine and I really appreciate the attention to detail which will be completely hidden and unappreciated by non-techi morons like me.

ABC jazz digital radio is on low, we have eaten and showered, MAM is down the corridor in her art room watching a utube on how to fit the Slomo to her Lady Ann frames. I click and drag the 3D model onto the 2D page a few times. I print this off. I ponder and experiment a few times, settle on a process and away I go. The results seem to have worked. It was all simple. The punch is made from a drill shank and a previously drilled piece of steel, used for making holes in brass shim. It was relaxing, enjoyable and a nice result. That is satisfying. That is fun. More fun to be added maybe next Tuesday as a good friend of mine does the hot test of # 967's new welded boiler and I will be attending, learn a bit more about the testing process and I will get to toss some black stuff onto its grate. That will also be fun, even if I have to get up at 3.30am and drive for 2 hours to be there for the match to be tossed in and after a long day of fun, the drive home again, but the drive home goes well as one reflects on the day and the things learned. The day will be chased with a couple of glasses of red. :P

Not a lot done last night, phone calls, customers and heritage railway related, however the front cylinder covers gaskets were cut out and the covers were fitted.
I read in the book that Brian Wilson suggests setting up the exhaust T before the steam T, I take heed of this and as I have not made the exhaust T I will start spinning some brass in the Myford tonight, before I knock off to watch Endeavour. (the only TV I watch all week) Maybe this weekend will be the air test.


Image

I used an old compass that kicks about the workshop that I used circa 1978 during my schools days, I sharpened one the points to be a bit knife like and used it to scribe the circles, then a touch up with the Exacto scalpel.

The Viton O rings did not sit well in the back of the exhaust sealing nuts,

Image

So I grind a piece of 1/*" HSS to clear out a relief inside the nut. That went well.

Image

MAM meanwhile is working on her Lady Ann frames.

Image

Unlike me, she likes to paint

Image

I assemble, the big event is getting close

Image

I had to make a trip to that dreadful place called Bunnings, to get some 1/8 ID vinyl tubinng.
Rummage up some air fittings I had, turn a piece of brass and braze it into a fitting, rig it all up.


Image

I call MAM to come and witness what is about to happen.

To be continued.
