Technical detail.

Select technical detail to view a description of our steam kit design.

     In 1926 Gresley responded to the urgent need for a very large 0-6-0  with the J38. With it’s large boiler and small (4’ 8”) wheels it proved to be a very versatile loco being deployed on both goods and passenger duties. They survived into BR hands, classed as 6F. They were only painted black although some of the early production carried a simple red lining. The last one was withdrawn in 1967. Sadly none of this class or it’s very similar sister, the J39 have been preserved.
      Our STARTER KIT is designed for ease of assembly and robust mechanism for reliability. It will enable the novice to build and run a working steam loco and learning about how it works and how to run it before embarking on something more advanced.
        To keep costs to a minimum it has a single working inside cylinder with ‘O’ ring seals. This will haul a good load and has the advantage over multiple cylinders that when tracks get oily, as they often do, wheelslip is very much reduced often allowing a single cylinder model to haul a heavier train than a  multicylinder loco. (This is due to the fact that at two points in each revolution there is zero torque, thus allowing the wheels to regain a footing.)The slide valves are driven by a simple, robust, and easy to set, slip eccentric gear. To further keep costs down and ease of assembly up, we have kept detail fittings to a minimum and omitted axledriven pump, bypass system and sprung suspension. A retrofit axlepump system and some detail fittings may be available at a later date.
      The tender carries the Methylated Spirit fuel and a supply of water. A hand pump is located in the tender which allows the boiler to be topped up whilst still in steam.
     These are ideal for those whose machining facilities or skills are limited or whose modelling time is at a premium. They are a good stepping stone from the 4mm and 7mm kits into the world of gauge one live steam, before tackling one of our more advanced designs.
     The loco kit is assembled using nuts and bolts and glue with no soldering required.  This will be done by ourselves where needed.  The boilers are built, tested and certified in house. The steam chests and cylinder units come part assembled with pistons and valves in place ready for you to carry out the final assembly and seal them up. Laser cut steel frames, rods etc will need a little cleaning up and some piloted holes opening out to size with a drill. The etched brass components are supplied as flat sheets with only the simplest of bends left for you to do. Where these bends are required there is a fold line etched half way into the brass, allowing a neat, sharp bend. The boiler wrapper, the cab roof and the footplate droppers will be formed by us.  All essential pipework will be formed with the fittings soldered in place. The wheels will be on axles and quartered.  Detail castings are in brass, nicklesilver or if only cosmetic, whitemetal.  
     All machining is done. Pressure gauge, screws ,nuts, rivets, ‘O’ ring seals, springs etc. are included to complete the assembly.  You will require some hand tools such as some fine files, small screwdrivers and spanners. Small pliers and tweezers are essential to position screws and nut where fingers cannot go. A drilling facility (which could be an electric drill on a stand) may be useful.    
     The model making hobby is littered with part built projects which have been abandoned because the modeller has hit a problem. We offer a ‘Get out of trouble service. It could be advice on the phone, a practical soldering training session in our works, correcting a mishap or setting valve timing. We include two hours free support or training session in our works and will try to advise over the phone during normal working hours. Over and above the two free hours there will be a nominal charge.
