I would be most interested in having a go with them. I know of the half-etch lines you mean as I went through my kit last night piece by piece. The chassis was partially assembled by a previous owner with the top hats soldered in place. I believe I have an email from Roy filed away on this very topic. Craig Hi Craig |

Re: Loco suspension
开云体育Hi Craig
When I built my loco I had a problem with some cylinder parts, and Alan Gibson very kindly sent me a replacement etch including a full set of side frames and stretchers. Whilst these are for a rigid chassis, there are half-etch lines so that the space for the hornblocks can be cut out easily and precisely. I didn't need these, so they are still in my bits box, along with a set of Gibson sprung hornblocks.? Would these be any use to you? (The frames were for SR 188 "Lew" but I believe the etches are the same as for the original locos).

Re: Loco suspension
开云体育Craig,
Sprung hornblocks all sound good, but unless you are able to get springs
that are perfect for the job then more often then not you end up with a loco
that wobbles along the track because the springs tend to recoil causing the loco
to rock side to side, that’s why probably the best suspension system isn’t
suspension but equalization ie: using rocker arms between each axle, which
basically keeps the loco stable but allows the axles to move up and down and
only slightly lifting the loco as they do.

This
is a very interesting topic for me as I have one of these kits.? It was a
fairly recent purchase (at huge expense!) and was described to me as being one
of the original 100 (?) kits that Roy Link had developed. Not so as it turned out - apparently this kit is a reissued variant by AG himself with all the important Roy Link chassis suspension bits discarded as a cost saving measure. While I have no 'cupboard of oblivion' for this kit it is at present languishing in the 'pit of despair,' likely until I can find an original to copy or get a fix kit of parts, sprung horn blocks etc. Craig On, Canada

Re: Loco suspension
开云体育The conical spring design I first saw on the old Tyco 10 wheeler that was
being sold back in the 1970’s it had a conical spring for the 4 pilot wheels and
worked very well. The link I gave you for the spring is about the right spring
to use, as available from there stock spring range unless you want to have a
custom spring made which would cost you an arm & leg, not to mention having
to perhaps buy 1000 minimum. I don’t know how much weight you have in your loco,
but if that spring tend to lift the drivers slightly you may have to add a bit
more weight to the loco, which will make it run better and pull better. And yes,
small end to the top or loco chassis and big end to the pilot or pony wheels
frames.

Hi Brian
Thanks - the conical spring idea is intriguing. Am I
right to assume that the narrow end of the spring is centred on and attached to
the loco frames, with the truck bolster moving laterally under the wide end of
the spring?
Putting in see-saw compensation would be ideal, but
unfortunately the frames, etc. were all built rigid when I started construction
of the loco back in 2001(!). As it was the first etched brass loco I'd ever
attempted, I kept things simple (crude would be a better description). Still,
all part of the learning curve....So, thanks for the offer of etching
components, but for now I'm stuck with the original arrangement.

Re: Loco suspension
开云体育Allan,
I have done this on a number of different loco's over the years, there are
several ways of doing this, the simplest way is to do it is to use a conical
shaped spring, that way it not only applies a down force but also creates a
sideways resistance.
I don't know how much room you have to play with but one possible spring
might be this one:-
<>
Another way of doing it is to set up all 5 axles so they have “see-saw”
arms between each axle meaning all 5 axles carry the weight of the loco, and
then have horizontally mounted straight compression springs to control the side
movement.
Let me know what you want I can probably photo etch some components to make
it all work how it should.

I'm just finishing off an Alan Gibson kit for an L&B 2-6-2t. (I
purchased it from Alan's stand at NEC Warley in 2001, which may be some kind of
record for slow work!).
Anyway, given the short coupled wheelbase and long overhangs on the Lynton
locos, it would be nice to incorporate some form of side control on the front
and rear trucks, so that they do their real-life job of helping steer the loco
into curves. However, my initial efforts have merely succeeded in lifting the
lead truck's inside wheel off the rail on curves.
Has anyone developed a satisfactory form of pony truck side control for the
larger n.g. locos, or is this best consigned to the "too difficult" file?

Re: Loco suspension
开云体育Hello Allan,
You are nowhere near the "procrastination" record, as?my decades old kit is still languishing in the "cupboard where kits go to die"! ?Needless to say, I am unable to offer any "first hand" advice, however I might suggest that you contact Paul Martin ( EDM Models ), as he has spent several years redesigning aspects of that kit, and may be able to save you some time ( and frustration ) with a list of "dos" and "don'ts" from his personal "alteration" experiences.
Good luck with your project.

Re: Narrow Gauge & Industrial Railway Modelling REVIEW
Marion and I are attending the Leighton Buzzard Narrow Gauge Railway Model Railway Exhibition on Sunday 5th August with the full range of RCL Publications and a selection of REVIEW current and back issues.?And there is an O14 interest in The End of The Line The Leighton Buzzard Narrow Gauge Railway will be holding their Model Railway Exhibition on Sunday August 5th 2018 with opening hours from 10.30 – 16.30. Entry is free with a ticket for a train ride (?10.50 for adult return, ?6.50 for children aged 2-17), or ?5.00 adults and ?3.00 for children without the train ride. Held partly in the unique setting of the engine shed the exhibition will feature a range of narrow gauge themed layouts in a range of scales, including 16mm live steam and gauges together with trade support. The exhibition also offers the chance to get a close look at the wide variety of steam locos based at the railway including the Baldwin 10-12-D 4-6-0 loco, one of 495 built in 12 months for service on the Western Front and currently the only working example in the UK. Layouts due to appear covering the larger scales include Cambell’s Quarry, Fen End Pit, The End of the Line, Gare de Brindlle, Papperwick Green, Wilstone. Q Dump, and Mulldale. In 009 scale the layouts include That Dam Railway, Holbeach, Royston Wharf, Achalraj, Castle Works, Heys Wharf and the Pym Valley Tramway. Trade support is from John Sutton Books and Models, Sweet 16 and Narrow gauge and Industrial Railway Modelling Review. A two train service will be in operation on the day giving the opportunity to see trains passing each other along the line. Train tickets which will give free entry to the model railway show can be booked in advance through our website at www.buzzrail.co.uk . For entry to the exhibition on the day only, tickets will be available at the booking office.

Re: Narrow Gauge & Industrial Railway Modelling REVIEW
开云体育I agree that as a complete item, the paper copy is always going to win for me, and I'd never want to replace mine with an ephemeral digital copy. Having said that, I do wonder if making it easy to obtain (for a fee of course) digital copies of drawings that have appeared in the REVIEW would be useful. If I'm modeling something from a drawing I always end up with numerous printed copies I scrawl all over. If it's a drawing from the REVIEW this means scanning the relevant pages. While not a huge chore getting the scale right, and keeping lines straight across double page drawings etc. is a nightmare. You could even limit this service to just the out of print issues, or issues over a year old etc. so as not to impact at all on the paper copies. I have a feeling Roy has offered to make printed copies of drawings in the past, but an easy to use system for digital copies (and yes I know copyright and digital locks etc. are a problem, but the layout issues go away if we are just talking drawings and not the articles) linked to the search-able index would be great.

Roy and I have been deliberating over this for some years. There are some substantial costs involved to ensure correct copyright protection. Digital?editions really require a different layout to support small devices which means double the production effort.

And we have had many people stating they prefer the paper as evidenced here. |

Re: Narrow Gauge & Industrial Railway Modelling REVIEW
开云体育I certainly would retain the physical magazine, that goes without saying, but I would certainly pay to have back issues in digital format on a year by year basis, perhaps something to consider similar to the way NG&SLG has produced a DVD.?That way at least you are adding to the catalogue, and producing something that might only need to be in a single desktop/tablet format, rather than something that needed, as you say, considerably more work to lay out. Regards, Mark.
