2 SECTION 1: BRIEF HISTORICAL DETAILS This kit, whilst designed to provide for the flat sided tenders of riveted construction fitted to the V2 class 2-6-2s, will also represent some of the tenders fitted to classes K3, D49, J39, B1, B17 and K4. Variations/Modifications incorporated into the kit Low front / High front: The first twenty V2s were fitted with Low front tenders. The remainder (except for eleven with flared top, low front, tenders not covered by the kit) were fitted with High front tenders. Fall plate: The original arrangement was for a fixed extension to the locomotive cab platform to suit the fall plate, which was hinged on the tender front plate. Starting with No (built 8/1941) the fall plate was transferred to the locomotive cab platform and a wood platform was provided at the front of the tender for the fall plate to rest on. The existing engines were brought into line as they passed through shops. Coal doors: From November 1940 the slatted coal doors, fitted to the high front tenders, were gradually replaced by solid doors. Frame guard irons: These were omitted from NE area tenders from 1938 onwards. Rear division plate: The tenders were built with a low division plate across the water pickup dome. From the mid-fifties onwards most had this plate replaced with a higher plate further forward together with a new design of water pickup dome. The angles, which attached the original division plate to the tank top, (part T29) were not removed. Inside the coal space a sloping plate was provided, probably at the same time. Spring Hangers: All the V2 tenders had short spring hangers. Earlier tenders paired with engines of other classes were initially fitted with long spring hangers. If you require long spring hangers then I will gladly exchange the short spring hangers supplied. Lamp brackets: Tenders for the GC section initially had an extra bracket on the left hand side. SECTION 2: CONSTRUCTING THE CHASSIS Note that many of the components handed left/right and care must be taken to ensure the correct component is used. I have not always identified left/right components separately but with care and common sense no problems should arise. Start by opening the holes in part C3 to accept short lengths of wire for the loco/tender flexible pipe connections. Solder the pieces of wire in place. Open up the holes in part C5 to fit the water scoop (part W3) and 0.7mm in the brackets to fit the water scoop cross shaft. Make all the bends in the stretchers with the bend line on the inside. Now open up the holes in the chassis frames (parts C1 & C2) as follows: 1/16 - to fit the compensation beam pivots 0.45mm - to fit the wire for the brake hanger pivots 1.2mm - for the brake cross shafts to fit the top hat bearings for the rear axle. Fold over the axle slot reinforcing plates, on the chassis frames, through 180 o with the half-etched line on the outside of the fold. Widen the slots so that the axles are a sliding fit. Solder the rear bearings in place. Solder the stretchers in place in the frame slots checking that the chassis is straight and square. Construct the compensation beam by soldering the two halves (part C6) together. Cut a piece of 3/32" brass tubing to fit between the sides of the chassis frames and solder the beam in place, centrally. Fit the beam using a piece of 1/16" brass wire as the pivot. Fit the wheel sets and test that the chassis works correctly. Wheel side control is limited by using the washers, part C19. 1

3 Solder the brake hanger pivots, from 0.45mm wire, in place. Fold down the brackets for the rear water scoop cross shaft on part C5 and assemble the water scoop as shown in Fig.5. Refit the wheel sets and retain as shown in Fig. 3. Open up the holes in the brake hanger laminations (part C7) - upper 0.45mm - lower 0.7mm and solder together. Attach the hangers to the pivot wires. Check the clearance between the brake shoes and the wheels making any necessary adjustments. Fold up part C20 and solder the vacuum pipe (0.7mm wire) to the inside face on the left side. The position of the pipe is determined by placing part C20 over the left side outside frame (part F3) and aligning the pipe with the half etched lines either side of the frame cut outs. Solder part C20 in place over the frames and central in the cut out in the top of each frame. Solder to together parts C22 & C23 to make the rear lower stay and solder in place in the half etched slots in part C20. Add the scoop stays mm wire - as shown in Fig. 5. Solder the front lower stay (part C21) in place. Solder together parts C8, C9, C10 & C11. File the ends of the cross shafts to a circular section so that the assembly can be fitted in place between the brake hangers. Complete the brake gear and water scoop operating rods as shown in Figs 3, 4 & 5. SECTION 3: CONSTRUCTING THE FRAMES / BUFFERBEAM / DRAGBEAM ASSEMBLY Fold over the sides of part F1 and solder the hanging plates (part F2) in position. Emboss the rivets on the frames (parts F3 & F4) including the rivets to locate part F9. Fold over the hornguide ties with the fold line on the outside. Emboss the rivets on part F5 except those indicated in Fig.6. Break off the spring stop brackets, which are only used in 7mm scale. File the top edge of the rivet strip flush. Solder the rivet strip to the top of the frames, taking care to ensure accurate alignment. Solder part F9 in place. Fold up the steps (parts F7 & F8) and solder in place on the frames. Emboss the rivets on the drag beam (part F10) and check the fit of part W7 in the locating holes. Solder parts F12 & F13 in place on the buffer beam (part F11). Solder the frames into the slots in the top plate and fit the drag beam and buffer beam. Solder together the two coupling hook laminations (part F14) and attach to the rear bufferbeam. Assemble the buffers and solder in place. Clearance for the buffer shank is very tight. You will possibly have to move the buffers inwards by elongating the locating holes. Form and fit the two vacuum pipe elbows from 0.9mm wire as shown in Fig.6. Lastly attach the remaining castings (W1, W7, B1 & B2). The locating spigots on the axlebox castings will need to be cut off flush with the inside of the frames to clear part C20. SECTION 4: CONSTRUCTING THE BODY Open up the appropriate holes, which are marked on the underside of the footplate (part T1), for the brake column, scoop column, water feed valve handles, water gauge and scoop indicator. Part L11 or H16 should be used as a guide. Solder 10 BA nuts, for body fixing, over the two front holes and the rear hole in the footplate. For a low front tender remove the first rivet strip from the front on each of the tank sides (parts T2 & T3). Now solder the coping plates (parts L1 & L2 or H1 & H2) to the sides. Accurate positioning is achieved by aligning the top of the rivet strips with the top of the coping plates. The appearance of the beading can be improved by rounding the top edge. Solder the cab door hinges (part T4) in place. Add the beading down the front edge using the wire beading provided. Make up the front and rear handrails. Solder the rear coping plate (part T7) in place on the tank back (part T6) and fold over the handrail. Fold up the rear steps 2

4 (part T8) and solder in place. Fit the rear handrail and lamp bracket (parts T10 & T11). Solder the sides and back into the slots in the footplate constantly checking the assembly is both flat and square. Make the tank top by soldering parts T12 & T13 together ensuring accurate alignment. Fit the lifting shackles (part T22, T23 & T26) to the tank top forming the shackles around a 1.2mm wire. For a low front tender modify the coal hopper by snapping off the shovelling plate extension so that it is flush with the front edge. For a high front tender modify the front corners of the coal hopper using the half etched lines and Fig.9 as a guide. Also open up the half etched slots for the feed valve handles. Emboss the rivets on the coal space hopper. If fitting the sloping coal plate (part T33) do not emboss the rivets that it will cover see Fig.2. Fold up the coal hopper, making the top bends first before soldering the hopper edges together. The next stage involves starting the front plate. The design uses two layers. Bear in mind the following: Open up the various holes to fit the castings first. Emboss all rivets and fold out the brackets for the water valve handles and brake/scoop columns. For a low front tender solder parts L5 & L6 together around their edges, detail as shown in Fig. 8, and solder in place in the slots in the coal hopper. For a high front tender fold up part H9 and solder to part H10 around their edges, as shown in Fig. 9. Solder in place in the slots in the coal hopper. Fit the lifting shackles (parts T24, T25 & T26) to the coal hopper. Check the fit of the tank top and coal hopper before soldering, from the inside, the tank top in place constantly checking the assembly is both flat and square. Solder the tank front laminations (parts L3 & L4 or H5 & H6) together. If appropriate, open up the slots in the tank front overlay to accept the fall plate hinges. Detail the tank front as shown in Figs. 7, 8 & 9. Test fit the tank front and hopper in place between the tank sides. For a low front tender, fold up part L8 and laminate part L9 to the rear. Slide this assembly over the hopper and behind part L5. If all fits properly the remaining soldering can be done to attach the hopper, front plate and top plate. For a high front tender, fold up part L12 and laminate part H11 to the rear. Solder parts H13 and H14 in place as shown in Fig. 9. Solder this assembly over part H9 and against the cut out in the hopper. If all fits properly the remaining soldering can be done to attach the hopper, front plate and top plate. Either fit the raised footplate support (part T34) and the raised footplate (part L11 or H16) P15) or the fall plate (part L12 or H17) and fall plate hinges (part T35). Anneal the hinges on the cab doors (part T5) by heating in a flame, then bend to shape around a piece of 0.45mm wire. The hinge pins have been made too long so that they can be bent over to stop the doors falling off! The brackets to clip the tender and engine doors together can be made from.3mm wire. The remaining parts can now be fitted as shown in the diagrams. I hope you enjoy building and using your tender as much as I have enjoyed researching and designing it. If you have any problems with the kit or any criticisms or suggestions please contact Brassmasters. Martin Finney - March
