Ragazzi,
ho trovato in rete un bel testo (secondo me) di modellismo navale,
ship modeling simplified e lo sto studiando...
ma purtroppo il mio inglese fa veramente pena e san google non mi ha aiutato molto....
Comunque sono arrivato al capitolo della simmetria delle ordinate dove è descritto un metodo che purtroppo non riesco a decifrare...
vi faccio copia e incolla sperando nel vostro immanchevole aiuto!!
Place a bulkhead frame from your
kit on a sheet of thick paper (manila
folders work best) and trace its outline
(1). Remove the bulkhead frame from
the paper, and cut around the outline
with a pair of scissors to create an exact
paper pattern (2). Next, fold the paper
pattern (3), making sure that the upper
outer edges are matched and clipped or
stapled together before you crease it in
the middle. The crease will produce a
true centerline and show if the lower
outer edges are cut unevenly or if the
keel slot in the frame is off center.
If the outer edges are misaligned,
remove the excess on the pattern with
scissors to even out the edges of the two
halves. Return the folded pattern to the
bulkhead frame (4), mark and file off the
excess on the frame itself, and draw the
centerline (C). If the keel slot is out of
center with the pattern, mark it on the
bulkhead frame.
Now repeat this on the other side of
the frame by just turning the pattern over
and aligning it on the previously drawn
centerline (5). Next, correct the bulkhead
frame's outer profile by filing off any
excess you have marked. If the center
slot is out of alignment with the centerline,
glue on thin strips of wood to fill
one side and remove the excess on the
other side. Finally, draw the centerline
on the top edge of the bulkhead. This
mark will help line up the frame with
the keel during the actual assembly.
Repeat this procedure with every bulkhead
and you'll have a symmetrical hull
profile.
Thanks!!!
