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.
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.

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.

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?

I agree, they look excellent.

What is expensive ? Hard for me to answer, as I do the drawing via Solid Works and I send them to Mike, I requested high resolution for the wax prints and white bronze . (I am self taught in Solid Works, I got the 600 page text book and from ground zero to the end over many evenings some years ago)
Previously I did the steam chest covers, then the expansion link supports. These were in silicon bronze. The smoke box saddle was in white bronze and I was impressed.
Mike takes care of the shrinkage allowances.
Chat to Mike about your possible projects. I have found him most helpful and the results most pleasing. http://stanier-engineering.com/page/our-contact-info/

Looking at this Gromit I can see that senior management will have the red editing pen out again on these tender frame drawings.

I was hoping you'd indicate the price you've paid for these beauties so that we can all individually decide whether it is something for us as well (we all have different pain treshhold ), but if you cannot (or do not want to) go public with this, that's no problem at all. I can ask Mike directly

Best to ask Mike what a set of 4 castings like these will cost you and postage.

The lads get stuck into making swarf. Took them all day. The red editing pen was out frequently and the 3D and 2D CAD drawings updated.

The lads put some hours in the Red Room. There was hope to have the tender frames wheeled by the end of Monday, but nah, too much gossiping.......
A few mods and additions to the Tender frame mill fixture for drilling the axle mount back plates and castings.

What is the distance between the axles on the tender?
I ask because you may be able to fit the Lady Anne Slomo that does not use a chain.

Food for thought.
88.9mm however if you fit a loco mech then only one axle will be driven, unlike a loco where the driving wheels are coupled so perhaps one wheel connected to a slow mo may have problems with skidding ? I certainly did not think of fitting a loco mech and Terry never mentioned this in out phone chats.
As I learn more about this little steamer construction I would have never bothered with the pump and fitted the Slomo into the loco, but alas I was too late when I discovered the value of the Slomo, so the tender was added to this freelance design.

Senior management works on her loco
Close to the test steaming, maybe this weekend.
There is some pondering over the plumbing and boiler fittings.

The Lady Anne SSP Slomo fits between the rear axle and middle axle.
All the locos I have fitted with this type of slomo have not experienced 'skidding' while pulling a dead loco that exceeds the weight of the loco pulling:

More holes, no threads in the backing plates was a recent decision from Senior Management after some discussions with the workshop head foredog.
Then the Tender frame was wheeled and placed next to the loco chassis for the first time, just for kicks and giggles.

Interesting, however I have had the tender Slomo on hand here for many months so it is too late for a new mech and redesign. As usual when one learns more with the passage of time, however if it helps others in the future.

Looking at your video, that is how locos should move. That is sweet. When one reads of people fussing over details, being critical of details and realistic modeling and then their locos look a whippets chasing cats around the track .............................
