Are these wheels for the loco or tender?

These are the tender wheels. The Loco has is drivers, it all goes around on air, boiler in the frames etc, but the trialing pony wheel set is yet to be done.

I think you mentioned a while back you will be installing a SSP Slomo in the tender?

Terry recommends using ball bearings on the axles of wagons or tenders fitted with a Slomo, info below:

He is a top bloke, I have been very happy with the units I have purchased from him.

Yes, Terry has been very helpful, I have his supplied ball races for the axles.The Slomo will be in the tender, because I know more now than I did back then and it was too late to fit in the frames and be done with the water pump which is not needed for the wet leg coal fired boiler, but it is going to be there for a trickle feed for extended runs. The tender wheels are just over the recommended minimum diameter and I have RC car ball in bronze steering pivots for use as the draw bar between loco and tender for full movement with Zero back lash/play so hope fully no jerky jerky. The draw bar length will be adjustable to suit the track curvature. The POR curves are tighter than I would have liked but at other railways I can couple up closer for better appearance. Well that is the plan..............

The draw bar will make a difference as shown in my early experimentations with inerita devices (before SSP Slomo was a commercial product):

I like the idea of the "slomo" in the tender. While I greatly appreciate the contribution it's made to the realistic motion of small steam locomotives, I find that one thing I do not like is how difficult it is to hide the unit between the frames of a little 0-4-0. On a six-coupled locomotive like Lady Anne there is a good hiding-spot between the centre and back axle; it's not as visible. But on an 0-4-0, where one would expect to see quite a bit of open space 'tween the frames and axles on a "real" locomotive, there's a big clump of gears and chains. Putting one in the tender I think is a great idea.

Yes, the bulk of the Slomech is obvious, but to my eyes far less offensive compared to seeing garden railway locos doing their best impression of 4468 going down Stoke Bank in 1938. :cry: I discovered the Slomo mech after I had started on this loco build, so a tender was added to fit it. Also I sourced a method for Zero back lash for the drawbar. More on this later. However with the tender Slomo there is still sprockets and chains between wheels and the two axles.

So far nothing has surfaced that fits the need of the Llewellyn Loco works No1 tender. So senior management have been working on the drawing for an investment casting for the dummy tender axle box and spring. These are being cast by Mike at Stannier Engineering in NZ. The drawing is created via 3D CAD then an STL file is emailed and he 3D prints the wax and has them cast (white bronze) and will ship to Australia in the near future.

Senior draftsman at the Llewellyn Loco works has also worked on the drawings for the Pony truck. It will have bronze split bearings so a 45mm axle set can be quickly installed via 10 BA bolts. The workshop team will tonight make a start on the frame stretcher that the truck pivot bolts to and the grate removal pin.

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:
