LNER Class Y7
Kit Composition. The main body and chassis components are etched in
brass with cast white metal fittings. Cab interior is detailed and a cast
backhead is provided. Alternative castings are included to cover some of the
modifications and differences between members of this class of loco that
existed during their working lives. The etched brass boiler is pre-rolled and
wire, screws, bearings etc are included.
This kit has been designed to provide a set of quality components that will
allow the modeller, who has basic kit building skills, to build an 0 gauge
model of the prototype to a standard of detail that is suitable for operating
models on most 0 gauge layouts.

  • Page 2: General Instructions

    GENERAL INSTRUCTIONS Please read this section carefully especially if this is your first etched brass kit. Many modellers fight shy of working in this medium but the basic skills are relatively easy to acquire. Once you’ve learned how to form and solder brass you’ll find all kinds of modelling possibilities will open up for you.
  • Page 3 than 145°. I sometimes use it for small spot joints on handrail wire, lamp brackets HMRS transfers, sheet number 18 contains NER loco & coach insignia. Details etc, but still use extra liquid flux. and an order form can be obtained from HMRS Transfers, Brian Webb (volunteer sales officer), 8 Gilpin Green, Harpenden, Herts, AL5 5NR.
  • Page 4 Three-dimensional parts are formed by folding. On an etched brass kit the fold 22. Painting is a vast subject that cannot be covered fully here. The important thing lines are normally half-etched on the inside of the fold. You’ll be able to fold most with a metal model is to get a good base coat of primer.
  • Page 5 Forming Parts. While the boiler in this kit is pre-formed, other forming is best Fit lubricators, hopefully you have already decided the type you wish achieved as construction progresses as this enables the parts to be adjusted to to fit and have drilled the required location holes as you removed the each other.
  • Page 6 21. I prefer to fit the roof permanently with solid NER Class H, LNER Class Y7 solder joints along all of the top edges of the cab. I will then paint and fit interior 19 members of this class were built by the NER, with a further five being added by components through the doorways and back the LNER for dockside and light shunting work.
  • Page 7 20. The cab roof provided represents the sheet steel roofs I think that these improvements have refreshed my Y7 and moved the standard of 7mm square the finished model up a level. Although I have learnt much and improved a lot over ventilator fitted to the locos in later years and reflects what the roof looked like on the preserved locos in 1988.
  • Page 8: Footplate Assembly

    Footplate Assembly Fold up the lamp brackets (parts 35). As Front these are a little vulnerable to damage I footplate 1. First fit the buffer beams (parts 2) to the footplate (part 1). These protrude about reinforce the folds with 60/40 solder. Hold 1.5mm above footplate level.

  • Page 10 Solder 3. Pre form and then Make final adjustments In common with the other kits in my range I solder length when soldering have included split pins to support the beading (parts 5) around Into position handrails. These are fairly easy to use and the cab openings.

Check all round that you are happy with the alignment of the two assemblies. Then with an equal amount of footplate either tack solder together so that smokebox and side.

I the best shape that then pass drill shanks through the crankpin holes to you can align the laminates. Check by eye that the drill shanks are parallel and square to the rod.
  • Page 15 Once happy with the spacer solder it into place. Then fit the smoke box back (part 17) When happy with motor again positioning the top at the etched centre position tack solder marks. Work from the top around each side mount to frames and soldering on the outside face.

Before folding motor mount I the first choice for the majority of modellers and these would recommend checking can be used on the Y7 very successfully after a little screws for an easy fit. If required modification work on the chassis etch.
