Hi Dave, Easy, It's a small rectangle of P280 wet-n-dry paper that I use to clean off rough edges
and fettle plastic mouldings. The smaller whiteish piece is the slide top to my fine drills box.
I've just used some super fine scales and what's shown is that wheel sets themselves vary by quite a lot.
My fully finished (except decals and a little paint) with the lead infill and chain and Alan Gibson wheels -- - 17.94 grams
The damaged one with the lead infill, but no chain due for a little more paint & decals with Dapol wheels - 20.18 grams
The almost made, again needing more paint and decals, no lead infill or chain fitted with Hornby wheels - 19.05 grams
A running session on St Oval with all three. The forwards speed of scale 15 mph and 20 minutes fine, reversing 3 full circuits
at a scale 6 mph again no problems. As can be seen these are very light, yet in reverse were pushing between 8 & 10 wagons,
due to being wagon numbers 9,10 & 11 in the train.
I was never intending to have an engineers train, but now have 2 x Catfish, I crane, 2 match trucks, a mess van, 3 soon to
be 4 Mermaids, a Borail with a load of 60 ft lengths of rail and still to build a Dogfish and Shark brake plough. Perhaps another
Borail with sleepered track load ?, or even a Whiting sleeper wagon ?
Oh and out of boring interest I believe the first 89 Mermaids were ZJO DB989000 - 989088 with no vacuum braking, the ZJV
were DB989089 - 989638. On checking some pictures it would seem that many if not all ZJO's were given vacuum brakes. This
is guess work, but noted patches of red-oxide paint on sides over painting something ? probably the ZJO code ??
If any reader knows better let me know.
