Maybe, as a service to the forum, we could list plans worth avoiding?
I've got a set in front of me: HMS Inflexible originally from the Nexus plans service at 1/192nd scale. Two sheets, available as MM1246 from myhobbystore. The first sheet is an (initially impressive) elevation and plan view. David Metcalfe is listed as draughtsman. I'm expecting a lot. But wait! There's something fishy here!
The draft looks suspect. Out with the ruler. It's a scale 37.8 feet. The original vessel? From 25 to 28.6 feet.
There's no "step" to support the inner prop shafts that I'm sure was present. And the rudder's well wrong.
Meanwhile Q-turret can't train past the rear superstructure without knocking chunks of steel off.
I've scaled up what I can to 1/96th scale, using Burt's plans as a better guide to "distances" (from the 1/500th scale Invincible in British Battlecruisers of World War One, Excel, a magnifying glass, and some tweaking to hit frame locations) and the Nexus A-turret ends up too far forward, or - rather - the hull would be too long if this is correct.
The angles on both fore and aft superstructures do not come close to Burt's, which seem to allow the 30 degree cross-deck firing available in the original of the class. If I tweak these angles to fit, two of the Nexus funnels would fall off. Or, at least, overhang the superstructure badly.
Ok, what of sheet two? This is a lines diagram. Elevation and plan again. Should be perfect for making a hull, once sections have been drafted. Hey, the "step" is here. But...
While the draft is correct, the bow's wrong. The stern is wrong. The sheer is simply amazingly wrong. These plans do not show shaft or rudder positions (so I can't check the pp length, nor locate prop shafts accurately, nor fit rudders at the right width or angle). There's a plan of the signal deck on here, but no other information regarding the superstructure where it's hidden from view.
There seems to be little sense in looking at these at all. They are over 90% worthless. £12.50 - not including P&P - down the tube.
