Something from while the forum was off-air (which is why you get two blogs in a day). Next off the rank is this Hop 21VB/vac’ fitted 21 tonner/HTV (if you insist). So many descriptions for what is a relatively simple vehicle. Another variation for Sharpwit, if he’s watching.

 

This is based on the excellent Parkside kit for the unfitted version, which is much the same, albeit with different end struts and a vac’ cylinder bolted on. It’s easier to go this way than to add more ribs to the Parkside rebodied HTV. The vac’ cylinder was reclaimed from an abandoned Airfix/Dapol Presflo, and the shrouded roller bearings were spares from one of the Chivers 21 tonner kits. The brackets and sundry other details were made from scraps of plastic. Prototype details were – inevitably – taken from Paul Bartlett’s photo collection. This one will be lettered for ‘House Coal Concentration’, assuming the ancient Woodhead transfers work.* The remaining livery elements will come from John Isherwood’s excellent Cambridge Custom Transfers sheet. A version of the scheme (this is ‘Freight Brown’ rather than Bauxite and with the later boxed numbers), can be seen in this shot from 1967:

For anyone else who fancies a go, the photos I used for the brake detail were these:

These shots of the model show the linkages:

Note that the actuating linkage/rod passes in front of the wheel with more than sufficient clearance. Normally, these go down the centreline of the vehicle but can’t on this because of the hopper being in the way. The steps on the ends and the hopper discharge levers come from the Dave Bradwell hopper underframe etch secured with a staple of wire which was melted in and reinforced with epoxy. The next jobs are the end struts and handrails. These look like a veritable cat’s cradle and are slightly different to the last 21ton hopper I did (covered in full on the old forum), despite the ends being similar. The triangular bracket nearest the vacuum cylinder is mounted on the support strut rather than on the hopper plating (this is true of both ends) so as not to interfere with the cylinder. You can see this clearly on the prototype shots. The two photos below illustrate the arrangement on a rebody on an LNER chassis. The technique should be similar:

Excellent -- so it's a 1958 build : one of the 1/149s that was 'cylinders in use' or one of the 1958/59 last Pressed Steel 1/146 batches some of which were also..? (The pre-1/149 1/146s that were built 'cylinders in use' had spindle buffers, according to David Larkin's 'Middle Era' book, and yours look like self-contained...)

 

Good stuff as ever though.

Hi John, thanks. No, spindles (ABS castings), so a '58 build (I think), the shanks on the self-contained alternatives - which I didn't have in stock - would be about twice the diameter. The white background and reflection from the whitemetal is a bit misleading. Just before the weather turned it recieved a coat of red-oxide, and has now progressed to the lettering and underframe painting phase. I'll take a picture next time the light is right, but that might well be in a coat of paint or two's time...

Hello Adam.

I'm doing one of the vac braked versions using bits from vac rebody and a unfitted original body kits. I stumbled across your blog half way through - nice work.

I have a question re. the vacuum pipe run from one end to the other of the wagon - do you have any photos of what happens to this at the platform ends? I presume it just dives under to connect with the hose at the non cylinder end, and does this via the cylinder at the other. Paul Bartlett's excellent photos aren't much help with this (for a change).

Thanks Adam, sorry about the delay in thanking you too! Looks like not much of the pipe can be seen. That photo comes from an interesting set, great that things like that were captured.
