Details ain`t everything.......
I suspect , like a lot of railway modellers, I could`nt see the point in struggling to build a locomotive kit to the same standard of finish as Bachmann and Hornby have been producing since my first purchase of a 4mm Bachmann Jinty, in the new highly detailed standards, back in 2005.
For a long while I drifted away from loco kit building in 4mm, not that I ever made larger locos of 4-6-0 or 4-6-2 types, I did`nt need them for my end to end set-ups.
It did`nt matter that nearly all of the RTR locos purchased with outside valve gear had dog leg coupling rods and trembling piston rods and linkages when powered up on the test track. Binding and poor running did`nt matter either as I needed to change the wheels to 18.83 guage in any case which immediately improved their performance.
Having had a preference for P4 modeling since the early 1980`s there was an added bonus in that the RTR locos I was interested in had one fully sprung driver axle ,so providing a small amount of compensation and maintaining good electrical contact with the track. All such converted RTR stock has run faultlessly through my P4 pointwork.
Sadly, my more recent RTR purchases have lacked the provision of a sprung driver and those with a long wheelbase have proved to be too unreliable when converted to scale profile rims ( Bachmann SDJR 7F).
With the onset of retirement has come the opportunity to rationalise my 4mm loco collection and with it the realisation, to me anyway, that my kit built stock still hold their own with the quality RTR we have had available to us over the past 10years. There are a couple of provisos ,however, and that is the kit built locos superstructure should be in etched brass or nickel silver. RTR locos should have replacement coupling rods ( usually using the Alan Gibson etched replacements).
Etched brass kits emulate more realistically the sheet metal fabrication of the protoype, particularly the edges of footplate and cab cutouts etc which photograph much better in closeup.
Likewise, when looking at the motion parts of RTR locos the coupling rods are far too thin and unconvincing especially the crankpin boss profile. A lot of RTR locos in close up appear to have running plates a scale 1 inch thick or more and overall look `plasticky`
Cast white metal loco kits , for me , do not produce a fine enough finish.
So, for me, I have purchased my last RTR locomotive, sold my last whitemetal loco and constructed my last etched brass kit in 4mm scale at least.
The last Whitemetal Kit.....................
A Kemilway BR 3MT with portescap motor.
Good for it`s time (1980`s) but a lot of errors in bodywork design. Has sprung compensation. A beautifully designed etched chassis kit .
Constructed about 7 years ago and sold last year.
Replaced by the far superior Bachmann Class 3........
Replacement Alan Gibson wheel set and coupling rod set which fit the models wheelbase precisely, enabling me to re-work the movement of the working parts.
She does`nt have a sprung driver, so has no compensation at all. Yet being a short wheelbase is very surefooted through P4 pointwork. All my other non sprung RTR converted stock has been sold.
To me she is the best RTR Bachmann production......perfection would be that missing sprung driver...........
Here she is with the last etched kit.
