The Home Machinist!

From the original development team of Solidworks comes OnShape. Worth a look, as it is essentially the same but free for education use. The commercial use "professional" version is also much less expensive than SW. Plus, it will open Solidworks files.

Time for some test prints! I promise to print them in gray next time, as the black makes it difficult to see the details. The laser cut wood frame is next. ADK thumbnail_file1-7.jpg thumbnail_file-10.jpg thumbnail_file8.jpg thumbnail_file3-5.jpg thumbnail_file2-5.jpg thumbnail_file6.jpg

We haven't been resting on our laurels with the Kozo project either. Here you can see a low-res print of the split journal with the roller bearing shown inserted. This journal will sandwich a laser cut steel frame for a durable assembly. More soon. ADK thumbnail_file2-4.jpg thumbnail_file-9.jpg thum...

Nice CAD model! How do you like working with MoI?

Love is not a strong enough word. It is excellent for work like this.

With the help of some serious period scholars, I have heavily revised the pedestals and springs. The pedestals include the interior springing for the journals, and there is now a proper transom casting.

Enjoy!

Hi folks. As you can see, the prototype model continues to be refined as new information is brought to light. Here, I was given a small photograph that illustrates how the pedestal was cored. I was also shown the transom casting that attaches the side beams to the spring plank. These trucks will be ...

Railroad Model Craftsman had drawings many years ago. Not sure when, but most likely the 80's.

I have found that Bachmann plastic couplers while being too small for 1-1/2 scale are just the right size for 3/4 scale and oversize for 3/8 and G scales. Ron, do you mean their G scale couplers, or their 1:20.3? Very interesting, as I build narrow gauge on in 1 3/4" scale on 3 1/2" gauge. Thanks! ...

Some test prints from the new SLA machine. These are low-res proof of concept prints, the production run will look even better. I'll fire up the laser in a day or two and run the wood parts. more soon. ADK thumbnail_file3-3.jpg thumbnail_file2-3.jpg thumbnail_file4-1.jpg thumbnail_file-8.jpg

UPDATE: This project is moving to the forefront while parts for the Kozo trucks are printing.

Here is a quick snapshot of the revised leaf spring assembly. Even though it is mostly hidden, it still needs to be beautiful.

More is better.

Today's installment: journal boxes. You can see how the roller bearing slots right into the piece for a perfect fit. If you look very closely, you can just see the tiny NBW that attaches the lid to the box. ADK thumbnail_file1-4.jpg thumbnail_file3-2.jpg thumbnail_file-7.jpg thumbnail_file2-2.jpg
