Paperscale to plywood-conversion

[Ruediger]

Hello!

Been a while since I last wrote, so I have a couple of questions now:

1) Has anyone experiences with converting a paperscale-model to a
playwood-model? If so: Do I only need to glue the paper to the wood or
should I better make matrices from the paper to be able to reproduce the
ship at any time?

2) Has anyone knowledge of a program outside the Amiga-World that is capable
to enlarge a PDF or a picture and print it out on several pages? On Linus
there is the "poster" program with kprinter - but it continuously fusses up
my prints.

3) Does anyone know how to make a glassfibre mould from an existing
paper-positive shape? that is - I can build the hull from paper, make a
negative somehow and then make a glassfiber mould into that negative form.

4) I have an old Parkzone remote control-set. The servos have 5 (!) lines
for control - ahhh... anyone with an idea where i could obtain replacements
for these servos? I ony know those three-wire models.

5) On mentioned Parkzone Remotecontrol ( from an Mustang P51D ) there is an
XPort-extension - a 3,5" Floppy-power-connector. Anyone knows the pinout of
this connector?

Any help or hints welcome!

Try searching for "multi-page poster printing" or something similar. Zdnet
lists
several:

Sounds like the electronics for those servos is in the receiver. (2 wires
for
the motor, three for the potentiometer.) The most wires I've ever seen on
a normal servos is four - from back in the days when the electronics
couldn't
reverse the motor voltage and, hence, required a center-tapped power
source. I'd try googling for them - or check ebay.

The results were there, but nothing really worked well. One program even
managed to distort the scaling from page to page!

Thank you a lot, though, for I didn't knew zdnet had a download-section.
Guess I gotta network my Amiga to have access to all the other files on my
network, especially the printer itself.

I opened one of the servos: Yeah, no electronics in it - I checked the
wiring and duplicated it for a Robbe servo - now I have a powerfull servo
for the steering control.
Thank you very much!

Do you have access to a video projector, or even an overhead projector?

When I scaled up my model a xeroxed the plans onto clear sheets, then used
an overhead projector to draw them onto larger sheet. Kind of a pain, but
it worked. Otherwise, if you can find a true video projector you could just
project your plan right onto the wall and start tracing..

The classic method is to use an opaque projector - the light source is on
the
same side of the image as the lens, and, thus, it projects based on
reflected
light. You can find them at art supply stores pretty cheaply, but the
cheapest
ones may distort the image. (Test with a grid of lines to make sure it
doesn't
distort the image.) You may be able to rent a much higher quality unit if
you
check around at audio-video and larger art supply stores.

I've had some luck projecting through thin paper by rubbing cooking oil or
shortening into the paper to make it more transparent. (You need to have
an ink or toner that resists smearing of course.) -Wm

I had an opaque projector in my cabinet - ner knew for what to use it - now
I have a working 1:200 ( roughly ) Tirpitz in the make. Thanks a lot, guys!

Ruediger, if you want to go from paper to plywood and save your orginal plans, first trace them onto construction cardboard, then cut out the drawing on the construction cardboard, this gives you a template to trace onto the plywood. I save all my orginal drawings and all my templates in case I want to build another model of the same thing or share them with a fellow modelers.
As for fibreglassing over the paper model, try using a release agent which you apply to the paper model first. You can usually get the release agent from craft stores. I have also used latex paint, apply several coats to the paper model and the resin won't stick to the paper model. Then again, why not just apply resin and fibreglass to the paper model and leave the paper inside the model, it's a great conversation piece. Good luck......fatboy999
