fun with kadees?
obviously you folk haven't had the benefit of springs going into orbit?
or a sudden droop in a coupler,plunging an entire express train over the incredibly high cliff that is the edge of the baseboard...or off a trestle?...( the droppers can drop, snagging on points etc..]
or the last train from the hidden sidings ending in a solitary kadee coupler and its box.......
or even forgetting the coupler height gauge is still o the layout....creating that mysterious short circuit that you've taken 14 days to look for?
Kadees, unfortunately, are not 'fit and forget' couplers.
they require 'servicing'.
spring replacement is the usual chore, in my experience....although on the No5's, sometimes troble can occur with the 'copper' centering spring in the box.
graphite lubrication is another chore....
to gain better operation, the actual moving jaw needs examining...if there is a rough outer face, this needs careful filing to smooth it off...otherwise mysterious problems occur.....kadees are good quality, but like all manufactured goods, that quality may vary.
I have had the pivot pin drop out, thus the coupler separates into its compnent parts...ackwardly!
I think most US modellers probably have a spare packet of couplers at hand....plus those surplus springs....
In the US, I got the impression most rolling stock was held together with small self-tappers....a problem with screwing a No.5 box, or others, to the underside of stock is that care is needed to ensure the screw doesn't pinch the box top together, thus restricting freedom of coupler movement.
since for years, the kadee was the only effective coupler in the US.....despite what most stock used to equipped with out of the box....folk put up with its idiosyncracies.....
incidentally, I found Kadees were pretty much inflation-proof....a 'used' pair selling for the same price as a new pair?
thus, at NMRA regional meets, one usually bought a pair of used kadees for a couple of quid..the same price as a packet of No.5's......but the used one's came with a free freight car attached!
thus, one's surplus freight cars had a fixed market value...the price of the couplers!
don't forget the 'weight' the goods wagons!
with todays free-rolling wheelsets, you might find your empty coal wagons have a peculiar affinity with the nearest uncoupling magnet?
Having a couple[r?] of old Peco wunderbar vagons (for DB)..with the old Peco Simplex couplers, I have to admit the actually look a lot less obtrusive than even the tiniest of hook-and-bar couplers from bachmannnn......especially if the drop arm is shortened...
I don't know why this coupler has been ignored so much.
It has many of the attributes of operation as the kadee, without the obvious drawback of looks that a buckeye coupler has......plus fewer moving parts.
plus, it is/was home-grown?
Hornby-Dublo used it successfully for years......Peco threw its mighty influence behind it....yet the horrible hook and bar won through?
