Revell (Revell of Germany and Monogram)

[zenrat]

Quick question.  Does anyone have the Revell vintage/fit the box-scale B-57B, and if so can they confirm the kit is 1/80 scale and the fuselage length is just over 9 inches, please?  Happy for a metric value, will convert.

Not in one piece.  And the pieces are on separate models.  I could measure from wingtip to engine for you though.  Let me know.
I could also measure the fuselage but as I replaced the tail with that from an Me 262 it won't be representative.

IS there such a thing as a 'Metric Scale'? 

It's just a number and is unit-less, by definition, surely?

1/10, 1/100, 1/1000 etc?

I meant a centimetre/millimetre measurement that I'd convert to inches.  If it's 1/80 then the fuselage could be a good basis for an Avro 729 build (https://www.secretprojects.co.uk/threads/avro-729-rocket-fighter-to-or-329-f155t.29980/).

1/20, 1/25, 1/50, 1/75, 1/100, 1/150 because they are easily decimalised; 1/35 is the outlier because it was created to compete directly with the Imperial 1/32.

1/18, 1/24, 1/48, 1/72, 1/96, 1/144 are their Imperial "equivalents" & are combinations of simple factors of 12; 1/32 is a bit of an oddball but Imperial rulers usually have divisions of 1/32 of an inch somewhere.

Many thanks and yes please (do you mean wingtip to nacelle edge or nacelle centreline?).  Could you measure the engine nacelle length as well (if possible)?

1/96 was a popular scale once, 1/48 is twice as big, 1/32 is three times bigger, 1/24 is four times ---

An engineer's scale is all 10ths but not metric -- 10ths of a inch or foot. So using the '60' scale is the same as 1/72 scale, just in tenths, not eighths

Sometimes when I read all these pieces on Imperial/Metric and various scales etc I'm just glad I spent most of working life with statistics. Basically made it up as you went along

No, scales are JUST numbers, they have no units so they can't be Imperial, Metric, or Dodecanese, no matter what the number is.

Sorry, I've only just seen this query. I've got a stack of the things. The box on this one says 1:80, although IIRC one of the others in the stash says something else (1:81? 1:82?).

Fuselage PIECE length is 232mm, but the tail cone is part of the one-piece tailplane assembly. Put that on, and the overall fuselage length is 239mm.

Wingtip to outboard edge of engine nacelle at approx 1/4 chord (remember the nacelles taper) is 175mm.

Fuselage to inboard edge of nacelle at 1/4 chord is 25mm.

Length of the engine nacelles, including intake and exhaust parts, is 82mm.

Hope that helps.

You're right, but Old Wombat's point about some scales making it easy to work in metric sizes while others make it easy to work in Imperial sizes is a valid one.
For Imperial scales, 1" on the model is a whole number of feet on the original, while for metric scales you can move the decimal point and maybe divide by 2 or 4.

[Gondor]

Imperial rulers usually have divisions of 1/32 of an inch somewhere.

I always thought that Imperial rulers could decide what they wanted

"1/32nd" scale is the architectural scale of 3/8" = 1'.

Most of the common inch-foot scales are architectural scales.
1/12 (1" = 1' or 1" = 12"); 1/24 (1/2" = 1' or 1" = 24"); 1/48 (1/4" = 1' or 1" = 48"); 1/96 (1/8" = 1' or 1" = 96") etc.

1/16 (3/4" = 1' or 1" = 16"); 1/32 (3/8" = 1' or 1" = 32"); 1/64 (3/16" = 1' or 1" = 64"); 1/128 (3/32" = 1' or 1" = 128") etc.

1/72nd scale 1" = 6' or 1' = 72" or 1/6" = 1' and it's relations (1/36, 1/144, 1/288 etc.) are a different animal.
Interestingly enough on a typography scale 1 point = 1/72nd of an inch and 1 pica = 1/6th of an inch, which
makes me wonder if there's a connection.


As Kit notes these are ratios and as such can be treated as unit independent.

However if using inch-foot rather than metric units it is convenient that one can
use simple ratios for scaling when you have dimensions in feet which means you
don't have to convert the dimension to inches e.g. 1/72nd is 1" = 6' a ratio of 1:6
so simply divide the dimension in feet by six and the product is your scale dimension
in inches. 1/48 is 1:4 so divide feet by four etc. 1/32nd (3/8" = 1') etc. are slightly
more complex meaning first multiply the foot dimension by three then divide by eight
to get the scale dimension in inches, or multiply by .375.

Many thanks Weaver old chap, extremely helpful.  I thought I saw 1:80 on a box in LHS last week, which prompted me to do the intial maths.

Assuming I've done my maths (and scaling up) right, your measurements have the kit's fuselage and nacelles slightly shorter than the Avro 729's fuselage and engine nacelles at 1/72, but nothing that can't be rectified, especially as mucho chopping will be required anyway.  But I think Ye Olde Revell B-57B coul provide the raw plastic.  I feel a trip to LHS while SWMBO is at her Mum's (and eventually a build) coming on!

Should sell well in the Ukraine. 



Of course this might well be only a rumour............
