This time of year, the discussion on CD dies down a bit. It's a great time for people to post CAD pics and designs. Please keep doing this.
Lewis is CADDing some pretty cool stuff here, and I hope he continues.
Travis also has a good point.
My advice to Lewis and others who post their designs is this:
Be clear about what you are posting. Give reference to what inspired you or gave you the idea to make this design. In some cases, it will be a unique design that is an improved method of doing what somebody already did, or it may be a CADded copy of someone else's design. Both are perfectly fine to post (especially at this time of the year). Confusion won't happen if you just give credit or reference to what helped you get to the point of where you are.
Issac Newton was a genius, discovered and proved many things, and still gave credit to those who inspired him.
He famously wrote to a rival, Robert Hooke:
"What Descartes did was a good step. You have added much several ways, and especially in taking the colours of thin plates into philosophical consideration. If I have seen a little further it is by standing on the shoulders of Giants."
The Giants he is referring to are Copernicus, Galileo, Descartes, Hooke, and many others. Each developed new ideas that would not be done without the previous study of a Giant. While Newton did great things, he still gave credit to those who gave him ideas so he could come up with improvements.
We can all follow Newton's example of giving credit where it is due.
Kudos to Lewis for having not only the skill to make these CAD designs, but also the guts to post them publicly. Thanks to Travis for bringing up a good point.
