It was Kirky correcting me, didnít see you getting it wrong Chris ;)

There are loads of markings on the real thing, I may just do Hanson logos, data panels and the end numbers, save my sanity!  :worried:

Fox do decal packs for the wagons in OO, but not N.

You can use a lot of the small details from the Fox Yeoman sheets

Iíve asked if Fox can downsize their OO gauge JHA sheet, theyíve come back suggesting the PTA sheet, which is better than nothing, but the right ones would make it easier! Already got a load of the Hanson logos cheers!

I think Iím nearly there now, NEM pockets are proving a pain, I drew them to the spec but they seem far too small, possibly because of how it prints, but no way a coupling was going in! Have enlarged everything and need to do another print!

Version 4 of the NEM pockets is now too big, V5 is going to be the one, Iím sure...!  :doh:

One Ďlegí of the bogies keeps failing to print too, bit weird, think thereís some issue with the CAD, but dunno what! May try making it fatter, but the same defect was on all 6 I printed tonight, so canít just be printer settings.

Happy with the wagon though, pending any changes needed to get the couplers to clear the underframe. Hopefully have an assembled one before too long!

In the mean time whilst they print Iíve made a start on the next wagon CAD. [Rolf Harris]Can you guess what it is yet?[/Rolf Harris]



Surprisingly awkward shape, I though itíd be quite easy! that angle makes it look very wide, I donít think it is, but Iím going to print it and compare it to a loco, may end up shrinking it in the X axis a little bit. The holes through the body add complexity too, redrawn them about 5 times, as every time you tweak the body I found they were in the wrong place! Still may be a bit far inboard, canít decide.

Thinking ahead somewhat... Couplers are going to be interesting with these - the bogies are a long way inboard, so I donít think bogie mounted will work, particularly as theyíre buffer-fitted. Something like the kinematic pockets Dapol include with their scharfenbergís would work, but thatís going to be an expensive way of equipping the wagons. Anyone else do standalone kinematic pockets?!

Like the look of the wagon.

On the kinematic coupler, the earliest ones I came across 30 years ago were unsprung, and designed by Roco for long passenger coaches. They worked effectively keeping buffers almost in contact on the straight, and opening up to separate the vehicles on curves down to R1 (9 in./228mm). There was just a single component which was moved by the bogie, and pivoted about a point inboard from the bogie centre. I have several still in service so Iíll look more closely at the principle, and have a think about how it might translate to the biomass wagon.

Thanks Mike, it was your comment on the Dapol ones that UK stock doesnít generally have such a large overhang that made me think of them, but £7 per wagon for totally the wrong coupler seems a bit daft.

Hadnít thought about a sort of Ďactuatorí, that could work. If you manage to dig one out a photo would be great, but no rush whatsoever, Iím weeks away (at best) on these!

Looks like Kato do some for the SP Daylight coaches which look interesting. Canít find a UK source, but may be worth further investigation.

These links: https://www.youtube.com/watch?v=QeDsJcPT46M and https://www.katousa.com/N/Daylight/maint/coupler.html show the Daylight kinematic couplers.  The fittings are built into the passenger cars, and can be added as an upgrade.

They work really nicely, but can be a fiddle to connect together initially.

Thanks, I watched that last night, I'm not sure if they'll work or not, hard to tell how much relies on bits integral to the Kato coaches. The end result is good, although the coaches don't have buffers, so I'm not sure they'd be long enough either. Ideally I'd prefer something I could mount on the end of the body I think, much like Dapol use, with a self contained pocket.

Are you not therefore tempted to just buy the dapol pockets and mount them under the buffer beam, not unlike their container spine wagons?

I would, but they only come in the Scharfenburg packs, which seems wasteful given I donít want Scharfenburg couplers. Iíd quite like a rake of 15 wagons too, and that gets expensive. Basically... Iím tight. :)

30 second glance at the print and it looks alright, drooped at a bit at one end, but thatís unsurprising given the length. Will cure it later hopefully and take a pic. They donít really use the WCML, so dunno what Iím doing building them!  :doh:

Thanks, thereís not enough movement in those, theyíre essentially fixed. Because Iíd be mounting them on the body it wouldnít end well!

Mike (Woodbury22uk) has kindly sent through some pictures of the Roco mechanism he referred to, which merits further investigation.

That might be why I could never get them to work properly  :headbutt:
