We are nearing our tremendous breakthrough, guys! The components of our miniature wooden roller coaster are being machined and will soon be assembled.
From our design files we made in AutoCAD Civil 3D, even the largest of obstacles were overcome.
The design files are still in the works, but that doesn’t mean that we haven’t started fabricating our li’l working ride. We tried machining the wood that was ordered a few months ago in anticipation…yes, we were excited. However, Basswood proved to be too brittle and created way too much dust.
We soon found out that machining Basswood would produce an error. Shortly after the above photos were taken a piece of track broke off cleanly. Since we had one more operation to perform, drilling the track mounting holes, we cut our losses and decided to inspect the ALMOST track sections.
Since a roller coaster design incorporates hi-order spline curves, the CNC milling machine provides the precision necessary to cut the track accurately. Basically fancy circle like bends along the ride offering smooth ups and downs.
Since our Basswood attempts failed repeatedly, we began our search for new building materials. The wood we have chosen to use due to its strength, availability, and cost was “Poplar.” So, we began to cut our designed supports out of the Poplar wood planks.
After building a fixture plate to machine our wooden structure, we began the machining operations one by one.
The machining was executed flawlessly. The Poplar was a success, and we made more of the supports. Each support took approximately 10 minutes to complete. This included spotting, drilling, and profile cutting.
Our next update will show the machining of our aluminum track brackets, more track sections, and possibly a rolling test of our miniature PreFab Wooden Roller Coaster!
