    Wow Bernd, these axle hung motors are very cool. It reminds me of some of your creations. They look like they really haul.

    Have you tried this technique???? (BTW) I love that little rail truck..........

    That was one of my goals, to show that a rubber band drive can be slowed down. The British have used a belt drive that I can't seem to source over here in the states. Here's a link to the CLAG web site showing belt drives. I believe what's shown is O scale drives, but the concept is there. http://www.clag.org.uk/axle-hung.html

    There is a source where you can buy these belts in England. LINK: http://www.nigellawton009.com/DriveComponents.html

    The rubber bands I'm using I found at Michael's craft store. They are to springy, just like you would expect a rubber band to be. The belts that Nigel Lawton sells don't stretch. I may wind up buying from him.

    I had an epiphany last night that I might try a worm drive on this little critter. Don't know yet. The jury is still out.

    I'll post progress as I attain it on this project.

      That's where I got some of my ideas from. I like to go outside the box of comfort. I look at other hobby's to see what can be used in what I do. Even though CLAG is more for large scale they have some neat ideas that can be used in other scales and gauges. No I haven't try the axle hung motors. To big for HO scale. But there idea of using air plane fuel line (silicone tubing) with a ball bearing stuffed inside to make a CV joint, like what I've used on the eddy current drive, is from their site.

      If you love this little truck, then you might really like the next three waiting in the wings. But first I need to develop this one so it runs better. I think I'm going to do away with the rubber band drive and go for a belt drive. Just ordered a dozen from England.

          While I procrastinate getting a structure started for the "structure build challenge" I made some improvements on the railtrucks drive axle. The original wheels I had on the rear axle of the truck where to large in diameter and would derail on the tight N scale radius track. So I took a pair of 40" diameter N scale wheels and mounted them on the axle. Works much better. I also made a brass floor for the trailer and added the axle. A couple of pictures.





          I'm waiting for a bunch of drive belts to arrive so I can test a new drive out for the truck. Perhaps I'll start on that structure building instead of procrastinating on it.[^]

            I finally have a good drive line. I got small belts from Nigel Lawton in England and got the right wheels and axle made. It now runs much better. check the video out.

            https://www.youtube.com/watch?v=fl9S...ature=youtu.be

            Every time I looked at that truck there was something bugging me about it. I finally figured it out. It was to wide and to high. That P.I.E. trailer is 8 feet wide and 8.5 feet high. Way to big for 30" gauge. A quick search on the net gave me the answer. The Main Two Footers were 6 feet to 6 feet 6 inches wide. Probably will make mine 6 feet high. So a scratchbuilt trailer is in the making.

            A quick bit about the battery. It's out one of these contraptions below.



            It's a 1S LiPo, don't know the millamps, but a fully charged battery last well over 6 hours of running like in the video.

            That's it for now. Got to work on my structure challenge or I won't have it done by the end of the year.

              Wow Bernd, glad you found the tracks....That thing is moving pretty good. I don't see any tires on the truck wheels, and I didn't see any slippage either.

              Looking forward seeing the scratch built box trailer....Nice work. I am far too clumsy to work on such small items. It's phenomenal dam good craftsmanship by you....

                Thanks Ted. I'll let you in on a little secrete. I have very small tools to work with to make those parts. [^]

                  Up-date on the railtruck. I think I finally have a good design for a trailer.

                  I drew up a design on CAD and printed it out. Glued it to a piece of cardboard so see if the design would work or not. It's sort of a goose neck trailer.



                  I then built up a frame using brass square tubing and soldered together using my resistance soldering rig.



                  Don't think it looks to bad. Much better design at 6 feet wide instead of 8 feet. Now to design a shell out of styrene.

                    Looks like we are getting closer to an operating rail truck.... I am wondering, what the trailer will

                    look like as I wait with anticipation.......and Bernd, as you know I am not a very patient man..... :up: [:-dopey]

                      Well then, I'm going to take longer to finish it just to torment you.

                          Ok Ted, since your not getting any younger I better post the latest I've done on the railtruck. Although busy with other projects I did get something done the truck. I shortened the trailer to 24ft. It looks much better shorter. Also added a shell and strips to show the panels used to build the body. That's it for now on this project.



                          Happy Ted?

                            As a matter of fact I am very happy to see 3 current projects receiving well deserved attention from

                            their master. Very good, now keep it up....What are you going to cover up the motive power with on the RT???

                            Just asking.....before you park it on the spur...

                              Haven't quite figured that out yet. I've got some ideas, but no Ah ha! moment yet.

                                Well I finally had that Ah ha! moment after I saw Louis' railtruck and read his thread on building it.



                                Louis, I stole your picture. Hope you don't mind. [^]

                                That picture and his thread gave me the inspiration to come up with something similar. So of to the computer CAD prgrom for a quick draw up of a similar cab.



                                Converted to a DXF file and into the CAM program to generate the G codes. The results.





                                G code file transferred to the computer that runs the mill and the program is dry run (no cutting being done)to check and see if it's what I began with. Looks good.



                                Fire up the mill and proceed to cut out the pattern.



                                I used spray adhesive to attach .020" thick styrene to a piece of MDF. Fastened that to the mill table and proceeded to cut out the pattern.



                                Peeled off the outer part to reveal the sides for the truck.



                                The sides are removed. A bit of clean up on the fuzzy edges and remove the sticky adhesive with some denatured alcohol.



                                I stuck on one side before cleaning off the adhesive glue to see how the design would look. I like it.



                                Now to finish up the rest with end pieces and a roof.

                                Bernd
