The Stony Point line.

Well here is my first attempt at 3d printing. Future looks very promising. Just a few changes for the next print. Just have to make the gear smaller. There is ment to be a hole in the centre. Have now fixed these issues, so the next print should be ready to go. This is a gear for my 03 shunter with split chassis. Once cured the print seems very strong. Fingers crossed

 

I had a broken original gear and axle. I just used a rubber ruler. And a bit of a guesstimate. Took 3 printouts to get it useable. The gear maker in Free Cad made it easy to make the right size gear. Just have to nominate number of teeth, then divide diameter, by number of teeth (ie. 10 dia ÷ by 22 number of teeth). I made the axle a bit longer than needed on the long end, then sanded to the required length. Its a nice fit, but I super glued it as well. Will put it together tommorow, and see how it goes.

Really enjoying the 3d printer. I have now finshed the gear with the correct dimensions. I also downloaded a couple of models from cgtraders.com I was recommended this site by Marklin of Sweden on you tube. Cost $5:54 au. For several cad designs. Will put the 03 shunter back together tommorow and see how long the gear will last.

 

Hi Gormo as they say proof is in the pudding. The 3d printed gear is brittle , but it takes a lot of force to brake it. As long as it last a fair while I can always print another gear. I just hate seeing models go to waste . As you say very poor design.

After testing the gear too destruction by running it flat out. the gear meshing with the original plastic gear, no problem. The week point was the axle which failed after 45min.
Much like the original did. Have now tweeked the gear, and fitted to the shunter. Runs very smoothly and I am now confident the it will last a long time, under normal operations. Will keep you posted.

Todays project. Painting and tarping all my british wagons, too make them feel more like VR wagons.

 

On the Facebook group, Gary wanted to know what we were doing over the weekend. Inspired by his warehouse builds and Gormos building marathon. I wanted to build warehouse for the steel rolls. So I started with a mock up. Using 2mm coated cardboard, made the front and sides. Then downloaded a image of steel siding. Reduced the size to suit. Printed out on matte photo paper and glued to building. I used balsa for the roof and front of the overhang. So 3 weekends later here is the result. Will add some 3d printed detail over the coming weeks.

 

3d printed a crane from Thingyverse. Had to print in parts. Used Elgoo Mars pro, with water based resin. This is the biggest item I have printed so far. because of the small build plate. I had too print the parts in four goes, The long section just fitted diagonally, and took 11hours too print. Very happy with the end result. Still have to lay some tracks for the wheels, and add a bit of weathering. Very slow progress here at the Stony Pt line. But better than no progress. Too busy running trains.

 

New addition to the Stony Point line VR Derm Railmotor RM 62. From IDR models. These ran on the Stony Point t line in the 70's. It's the most expensive item on the layout, but I have to say it's fantastic. Great detail, interior lighting. Front light and two red lights on the rear. Runs very smoothly.

 

New station platform made. Just used 2mm balsa wood from local hardware . The sides and supports made from 2mm screen board, and covered with scalescenes brick paper. Painted with cheap acrylic paints. Total cost $14 for both platforms.

 

Screen board is a white coated board used in the printing industry. I used to be a Screen printer and was able to source offcuts. Luckily my son is in the printing Industry and is able to supply, me with offcuts. You maybe able to get it from a printing supply company, but I'm guessing it would be expensive.
