I have finally started this build. I found some 1/8 inch dowels at my local hobby store that turned out to be 4 mm in diameter instead of the 3 mm they were supposed to be. This was not really close enough so I did some sanding on one of them to get it close to 3 mm dia.
It only took three attempts to get an acceptable result. On my first attempt everything came out way too large in diameter, so I unwrapped cut off some of the width of each part and re-wrapped it. The first three pics show that second result. It looked pretty good until I started the build of part 7 which is the breech block, I think. In the third pic you can see that the gun barrel is still too fat. It needs to be 9 mm or slightly less to match up properly with part 7. This was probably due the the extra thickness of the brochure paper that I used instead of thinner copier paper.
You can also see in the second pic some damage to the open end of the gun barrel. It takes a lot of handling and manipulation to roll all of the gun barrel parts around the 3 mm mandrel. I managed to put a kink in the thinnest part of the barrel where the mandrel ends. So before rewrapping the barrel a third time, I cut another short length of wood dowel to extend the mandrel and inserted it into the gun barrel end. That extension makes the unsupported open end of the gun barrel much shorter. I think that extending the overall length of the mandrel so that only about 3 to 4 mm of the open end remains unsupported would be a good modification for this kit.
The fourth pic shows the gun barrel unwrapped to a point where it can be re-wrapped. I reprinted the parts on copier paper this time and carefully re-wrapped the barrel to get a much thinner profile.
Finally, the fifth pic shows the final, acceptable part temporarily attached to the breech block. This time I'm pretty sure that it's going to work.
The lessons learned from all this is to put in a little more study of the instructions before starting a model. Waynes instructions for this model are comprehensive and detailed with loads of diagrams, photos and build tips. I think I just got a little overwhelmed with all of this information, so I just kind of jumped in and started building. None of my difficulties so far have anything to do with the design of this model, with the possible exception of the kink in the open end of the gun barrel. I think that can be corrected by simply extending the length of the mandrel as I described previously.
