Jumbo Cretors Oscillator Casting Attempt

<< < (2/2)

CI:
I was trying to get the various parts to look proportional, and was not having much luck.
Each revision of one part required revision of the other parts.
This is the sort of thing I work out first in 3D modeling now before I begin making patterns.

I originally intended to make all of my patterns in wood, including flywheels, and so I was working out methods that worked well as far as making wood patterns.
I learned that you don't necessarily want to try to machine some wood parts in a lathe, especially when the part gets roughed out, and there is not really a good way to grip them.
I had a flywheel rim almost finished, and was spinning the pattern at a relatively high speed in the lathe, and the tool bit snagged, and tossed the entire rim out in a rather dangerous way.
I added a router to the tool holder, and ended up turning the chuck by hand, and that was an infinitely better and more safe way to turn wood patterns in the lathe.

In the end I transitioned to 3D printed patterns, but I learned a lot when making these patterns, and I now I can make wood patterns if desired.

This is fascinating .......following along  :popcorn: :popcorn:

Some rather, um, interesting?  ways to use a lathe on wood...  I'll be  waiting way over that way...   :Jester:




Looking to be a great engine!
