    Looking good Bernd.

    What is the reason for a plexi version and a plywood version ?

      Is that all 'Z' scale Scott? wow...
      even 'N' scale would blow my mind, amazing.

        Thanks Karl. I'm testing what materials will work best with the ROBO configured as a router. Although you can cut think stock such as the plywood, 1/16" thick, it's a bear to hold down as I will explain when I get the post written up in the scratch build forum. The Plexiglas was a bit tough also. Explanations and observations coming soon.

          This is Good already. I'm going to learn a lot here. I will play too. I'll finish my guard shed.

            My first Challenge project is to scratchbuild a model of our house. It's a trilevel raised ranch. The lowest French basement level is concrete and Indiana Limestone. I'm still think about which routew to take on that. I did start in the main level framing and the South, East. and Northeast 2 X 4''s (.584mm X 1.168mm) studs are in place. CAD drawn and 3D printed so far.

            I thought that I would show all the parts of the Mack Truck before their date with my files.

              Like Bruce, I too have a date with my files to get things right.
              To assemble a white-metal kit, you do not need any special skills, tools or equipment. Every modeler that has ever built a plastic kit probably already owns the recommended tools:
              - several small files
              - sandpaper
              - brushes & paint
              - superglue
              - filler
              Clean parts of any flashing using a fine file, sharp razor knife, fine sandpaper, and 0000 steel wool. Small amounts of flash may be scraped away just using a razor knife.
              When satisfied with parts, wash them in soapy water to remove any mold release agents (talc powder for pewter, spray agent for resin) along with your finger handling oils. Rinse and allow parts to dry. (This allows the surface to be clean of any chemicals that may not allow paint to adhere evenly or smoothly).
              Assemble the cleaned-up parts but do not use glue, just test-fit the parts first. Do not use force to put the parts together, but use a file or sandpaper to
              carefully remove excess material to reach a proper fit.
              If all parts fit perfectly, examine the surface of the parts. Look for holes caused by air bubbles and other surface defects. Use a nitro-filler to fill the holes and defects. After the filler has dried, carefully use files or sandpaper to smoothen the surface. If you work carefully, you won't be able to feel where the metal stops and the filler starts.
              Determine whether to paint first, or assemble first (if in doubt, paint first), keeping in mind that glue used for assembly may not stick well or hold parts tightly when glued to a painted surface.
              You can carefully scrape away paint from gluing surfaces if needed.
              Use quality hobby paint ‐ not cheap paint. Quality paints use much more finely ground pigments which give a thinner coating ‐ thus will not hide details as likely.
              Assemble per instructions using ACC, resin, or epoxy type glues. Note that ACC type glues do not normally have good strength for large wall panels or other large or heavy assembly areas.
              This is what my Chevy Impala looks like from the package. (Picture below) Flash is indeed present. Some kits come very clean, others like this one needs some TLC. When it comes to the white metal kits, Alloy Forms wasn't the cleanest casting kits made.

                I've posted the SBS on scratch building Fredric Testard's Critter Shed in the "Startin' from Scratch Forum".

                LINK: https://railroad-line.com/node/1022584

                Major updates will be posted here in the Challenge thread with a link to the SBS critter building thread. This way down the road when somebody want's see what I did they don't have to wade through many posts of other participants on this thread. makes it easier to find information.

                I see we're off to a good start with many projects.

                  After missing the Challenge last year I decided to jump in this year. The first item is to scratch
                  build a piece of rolling stock. I "borrowed" an idea from Louis and wanted to make a blacksmith
                  car to use on the CC&W RR. In the future I plan on adding a few horses to the layout so that will
                  be the reason for such a piece of rolling stock.

                  Even though I model in On30, I use HO track and mechanisms then build the On30 on top of that.
                  Have an assortment of old, 70's & 80's, HO cars to steal the frames from since I hate to waste materials.

                  So here's the start:

                  ​​​​​​This is the chassis from and old Caboose. The end tabs were cut off and sanded the ends even. Also cut off the one set of steps
                  on the one end; I'll leave the other set to get aboard the car. The underneath details will be painted when I weather the trucks.

                  Added a weight sort of in the center to make the car "track" better. The sides and end are made from scale 2x1o's which were
                  grained and weathered with a combination of black/dark tan mixture. Not sure what I'm going to do with the stairs end but
                  I'll figure it out. Also will be adding some bolt casting on the sides.

                  Next will be to add the decking before making the blacksmith shed on the non-stair end. This will be done in between finishing
                  the new Machine Shop for the layout.

                  I'll be adding updates here with a little more in depth detail here: https://railroad-line.com/node/40907/page52

                    Not what you would call major progress, but I started the 1959 Chevy Impala, first picture, and filed away the fins at the middle section, second picture, to give it the 1960 Chevy Impala style. Also, filing away the 1959 teardrop style rear lights to make room for a new light bar across the rear for a 1960’s style look. This is the first ruff filing to get the contours and style I’m looking for. Continued filing and a new set of rear lights are yet to come.

                      Good start Larry, I'm also a believer in "waste not want not" I look forward to your next steps.

                      Very impressive start Louis, seeing things beyond what they originally are is the first step, but,
                      being able to see, and then create what they could be is an art and a skill, and one you have mastered and
                      shown us all many times.

                      I'm looking forward to seeing and learning from your work as always.

                        Karl thanks. With the price of things now days, including modeling, I try to get the biggest bang for my buck.

                      Thank you very much for the kind comments Karl. Now you have me under a great amount of pressure.

                        Lots of cool projects going on here.

                        Well - full disclosure, I started my project a little earlier in December. It is, however, a big undertaking and so still has a long way to go! Here is my quick sketch as I prepared quantities of timber for staining - and I mean quantities! The 830mm length has been increased to 880mm (34 1/2") and the tallest bent is 465mm (18 1/4") tall. Its a short line, logging/ mining railroad, so bridge building rules may be broken. Inspiration was taken from the Percy Burn viaduct on the Port Craig line at the bottom left of New Zealand (now a walking track).

                          I did a small update on the Critter Shed build. I show how I used the plans to do a CAD drawing that then gets used by the CAM program to tell the machine what to do. Still need to put in the parameters in the CAM program. That's next.

                            Hello all: I intend to join the 2023 Challenge with a scratch built structure (the "Ghostbusters" movie Firehouse).. However, I can't begin yet,
                            as I am in the middle of an unexpected & uncomfortable dental procedure, that includes meds.

                            Once I'm through this thing (hopefully mid-January) - I'll start immediately...appreciate your understanding.
