Llewellyn Loco Works #1
Re: Llewellyn Loco Works #1
That is an absolutely brilliant demonstration of the value of flywheel devices such as the SSP "slomo". I like the 0-6-0 one particularly: It is hidden much better than the 0-4-0 one. With its higher boiler, and lack of tanks, the Roundhouse "Billy" is particularly unable to conceal a device between its frames. Furthermore, I think it's still pretty useful to discuss the installation of the "slomo" device in trailing vehicles, because this allows it to work with any loco, including non-Roundhouse ones, and ones that have "inside" valve-gear or accessories like axle pumps.
Another device I find interesting for taming hyperactive locomotives is the centrifugal brake, such as one might find in the works of an old rotary-dial telephone. Somewhere online I saw a video of a Roundhouse "Bertie" with one of those in a tender. It pottered about the garden quite sedately, making a really good chuffing sound.

Re: Llewellyn Loco Works #1
I learnt about Slomo's via your videos and others after I had the wheels all done and fitted to the frames. So then it was tender addition. For me the loco must move properly, that is more important than scale details. I hope mine does this.tom_tom_go wrote: ↑Thu Feb 27, 2020 9:09 pm The dummy axle box and spring look great and I sure the tender will match the quality of the loco (the basic looking Roundhouse tenders would not match).
It is a shame the 0-6-0 Slomo was not available when you started building the loco as it does not use a chain drive and the Slomo itself has transformed the running of all the locos I have fitted with these devices.
Try doing this with a live steamer without a Slomo and at a realistic speed without the loco falling off the table:

Pony Truck Frame completed. While the just down the corridor, Senior management was dabbling with her paint brushes.

Re: Llewellyn Loco Works #1
Inspired by her oil on board morning, it was then to the Red Room and up stairs to the kitchen to bake off her smoke box. I am sure this was in MAM's thoughts when she chose the oven.

Re: Llewellyn Loco Works #1
Meanwhile the staff at the Llewellyn Loco works were working of the frame stretcher that the truck attaches to and the grate support release pin will be located.

Re: Llewellyn Loco Works #1
At the Llewellyn Loco Works the staff are working on the pony truck with split bronze boxes so the wheel set can be swapped out from 32mm to 45mm if required. However the parts making process should have been done differently, as it would have been much faster and more accurate. The workshop staff lay the blame at the feet of Senior Management #@^**!!!#@!&!***!~!##

Re: Llewellyn Loco Works #1
In between jobs at the Llewellyn Loco Works, the staff managed to sneak a foreign job in. They blinged up MAM's Round House loco's chimney cap.

Re: Llewellyn Loco Works #1
Yesterday arvo, senior management felt they needed some time in the Red Room, despite feeling like they had Covid 18.5 3/16" silver steel axle ends were turned, then the wheels pressed on. Did not go to plan. SIGH! One edge broke out.
So it was back to the lathe and a new wheel and axle and Loctite and all went well.
Management is dim, in hindsight, why did they not make it 0.01mm inference and heat the wheel to slip it on. Why ? Simply dim!

Re: Llewellyn Loco Works #1
Pony truck is done. The 10BA brass screw in the back of the Cannon type axle box is for injecting oil. Split Bronze bearing. Runs as smooth as silk. Later when the loco is complete I will measure axle loads and fiddle the spring to get the driver loads even.

As one half senior management enters his forth week of coughing and spluttering on 4 of his 6 cylinders the other half of management is working on her Lady Ann. Swapping out the fugly 6BA and M3 Cheese heads for hex.

Re: Llewellyn Loco Works #1
Nothing of great excitement, just making a start on the Rosebud grate and the ash pan to follow. 316 stainless.
Again, the lack of details in drawings to even mention the spacing, keep it all hazy to fudge the story. So I researched as much as I good in regards to 16mm coal fired and will give this grate a go to start with. It will be easy to make different versions if required. I plan using Gunnadah coal with is good stuff in the full size locos, but I am lead to believe not so good in the little grates. The grate is yet to be trimmed to size and to have half holes along the sides of the wet legs.

Re: Llewellyn Loco Works #1
The workshop staff at the world wide headquarters of the Llewellyn Locomotive Works made a start in the Red Room with milling 316 stainless to size and cutting 1.50mm 316 sheet for the ash pan. Meanwhile one half of senior management was plotting the upgrade cab steps on her Lady Ann build.

Re: Llewellyn Loco Works #1
The eagerly awaited shipment from New Zealand arrived at the doors of the Llewellyn Loco works and the staff are quite pleased. As usual, with hindsight some detail changes of the 3D CAD drawings would be welcome, but overall, they should do the trick. Cast in White Bronze from high definition Wax prints. Bravo to Mike, yet again. The staff can make a cracking start on the tender now.

Re: Llewellyn Loco Works #1
These castings are excellent
How prohibitively expensive are they?
Do you have to make shrinkage allowances in your CAD model or does Mike do it?
What other materials apart from white bronze can he produce these castings?
