Model Forum / Radio Controlled / Water Models / November 2005Paperscale to plywood-conversion
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!  SignatureSincerely Ruediger > Hello! > [quoted text clipped - 4 lines] > up > my prints. Try searching for "multi-page poster printing" or something similar. Zdnet lists several: http://downloads-zdnet.com.com/sort/3150-2088-0-1-5.html > 4) I have an old Parkzone remote control-set.

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. -Wm >> Hello! >> [quoted text clipped - 9 lines] > several: > http://downloads-zdnet.com.com/sort/3150-2088-0-1-5.html 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. >> 4) I have an old Parkzone remote control-set.

Thank you very much! SignatureSincerely Ruediger 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.. Tim > Hello! > [quoted text clipped - 23 lines] > > Any help or hints welcome! > Do you have access to a video projector, or even an overhead projector? > [quoted text clipped - 5 lines] > > Tim 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 >> Do you have access to a video projector, or even an overhead projector? >> [quoted text clipped - 23 lines] > shortening into the paper to make it more transparent.

Thanks a lot, guys! SignatureSincerely Ruediger Ruediger, if you want to go from paper to plywood and save your orgina plans, first trace them onto construction cardboard, then cut out th drawing on the construction cardboard, this gives you a template t trace onto the plywood. I save all my orginal drawings and all m templates in case I want to build another model of the same thing o share them with a fellow modelers. As for fibreglassing over the paper model, try using a releas agent which you apply to the paper model first. You can usually get th release agent from craft stores. I have also used latex paint, appl several coats to the paper model and the resin won't stick to the pape model. Then again, why not just apply resin and fibreglass to the pape model and leave the paper inside the model, it's a great conversatio piece. Good luck......fatboy99 -- fatboy99 |
