Designing a bracket

After I mounted the dynamo to the marvellous machine it had a little shake which gave me some pause. Because the piece is to travel many thousands of miles in the back of a transport truck I became worried about a failure. The solution was to create another bracket which attached to the top portion. As I looked at the space it became apparent that if I added a bracket here it would interfere with the next gear I was going to add

Telling a story with paint

Yesterday I mounted the dynamo armature to the largest gear on the 'MARVELOUS MACHINE'. I then designed and cut a bracket to mount the outer housing. I painted and aged the pieces prior to assembly. It was pure magic to watch it all turn. It was looking pretty good but I wasn't finished quite yet.

Dynamo

As I thought about what my 'MARVELOUS MACHINE' would do I decided the steam engine would power an electric generator which would in turn power the next device. With a little research I discovered they were called a DYNAMO when they were invented. On further research I found a photo of one I liked. I did a sketch to visualize how it would fit on a heavy duty bracket and have a gear to drive it. Then it was time to guild the routing files

Gearing up for fun

We've made plenty of projects with gears through the years but this is the first time they will actually move and interact. That meant they had to be accurate without any fudging. A friend sent me a link for a simple gear making program a while back and using it made it easy to create the DXF files for the gears.  I made five different sized gears all with the same sized teeth

Flying at the flywheel

The flywheel for the 'MARVELOUS MACHINE' was a fun little project. Creating the file took a number of steps but it wasn't overly difficult. The entire file was designed using EnRoute. The spoke vectors looked a lot like giant tear drops I designed one, then duplicated it and flipped it

Full throttle story telling

A simple electrical on-off switch would have done the job of turning my MARVELOUS MACHINE on and off. But a simple switch wouldn't have told the story I needed to tell. My MARVELOUS MACHINE is 'driven' by steam. To properly control suck a divide we needed a mechanical throttle, much like what one would find in an old steam train engine. I had built a similar throttle for our train steam engine last year
