Re: Llewellyn Loco Works #1
Senior management works on her loco
Close to the test steaming, maybe this weekend.
There is some pondering over the plumbing and boiler fittings.

Lady Anne chassis:
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:

Re: Llewellyn Loco Works #1
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.

Re: Llewellyn Loco Works #1
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 .............................

Re: Llewellyn Loco Works #1
I think you will be satisfied with the flywheel device being mounted in the tender. With the device not being on a driven axle, of course there is the possibility of wheel-slip on the loco itself when starting, just like you would get with a full-size locomotive. Depending how you feel about it one could argue this is even more realistic, requiring some finesse on the regulator while starting up.
I have a momentum device mounted in a weighted wagon and it seems to work fine with only one axle being geared to the flywheel. I prefer to run without R/C so mine is only there to stop it running "like a whippet" which of course is even more of a problem without R/C.
I too find videos in which the locomotives hurl themselves around masslessly almost unbearable to watch, especially when a great many of them also seem to suffer from badly adjusted valve timing. How the operators find the lumpy chuffing sound bearable is beyond me.
The only time I have noticed "dragging" being an issue is when I have allowed the rails to get very greasy. On greasy rails the locomotive is quite capable of dragging the momentum vehicle but it seems to be a transient effect and again a deft hand on the regulator would mitigate this.
With a hard coupling between your loco and tender I predict you will be quite satisfied with the "Slomo" being in the tender.
With respect to the tender by the way, I have never seen such nice, clean castings as those axle box/spring details. They really look good. That tender will be quite a handsome vehicle in its own right.

I will have a zero play coupling for the loco and tender, more at that later. The castings are all the witch craft of Mike Jack in NZ who does a lot of this for the ME world. I just supplied the drawings and as usual I see later with a fresh eye, mistakes and things I would change. The thing that tickled me was the spring leafs, I was worried about getting the impression correct for the individual leafs. I feel I got that right, yay!

Re: Llewellyn Loco Works #1
Management's cunning plan is to have simple and quick draw bar unhitching from the tender to loco via a special M3 cap head under the timber cab floor.
"Management said, one year, no worries, it will be nice simple quick Loco build job, eh Preston. Three years later here we are making draw bar drag box blocks"

Re: Llewellyn Loco Works #1
Where did you find M3 heim/ball joint
or are you making it yourself as well
when I tried to source some, the smallest I could find in steel was M5 or M6
anything smaller was either plastic or aluminium...

Re: Llewellyn Loco Works #1
To be honest I cannot remember now.
They have an aluminum body with bronze and stainless steel joint, M3 thread and 3mm diameter pin hole.
I thought I got them from https://knupfer.info/shop/
but I just had a quick look and could not find them.They might be there. (I use http://itools.com/tool/google-translate ... translator)
They are for radio control cars and planes etc.

Re: Llewellyn Loco Works #1
The ball joints are still available from Knupfer, from 2 - 4 mm.

Re: Llewellyn Loco Works #1
thank you guys,
so it is aluminium body ...
I was aware about aluminium and plastic ones, but was hoping to find steel body ones.
It will be interesting to see how will aluminium perform long term in this particular application.

Re: Llewellyn Loco Works #1
It should not be a problem, unless one thinks corrosion might be a problem , the aluminum encapsulates the bronze / brass bearing, the centre bearing is steel, could be even stainless ? I am sure it will be certainly strong enough.

Hi Darrell, I’m new to the forum but having dabbled in bicycle frame building myself I have come across your work before, I must say the railway side of things is equally impressive!

Thanks Garethh, of course you use Llewellyn lugs and castings for your frame making

I don’t do much in the way of lug work but pretty sure I’ve used some of your dropouts and bits and pieces!
