Re: How do I turn my DeltaCad design into reality? Machine cutting question
OK... I might be able to help out somehow. I happen to own a 20" x 40" CNC Milling machine - it might be a fun exercise to make some sundial stuff. Anyone interested should email me and we can work out the details for transferring your DXF information to me while retaining the "as designed" attributes. >From the message below: #1 I do believe that the DXF format does not use line width attributes. So, when designing your drawing for machining you simply draw the outline of the areas you wish to machine (or not machine). #2 To maintain fonts - you'll have to use a true type font and send the font file along with the drawing. The recipient can then install the font into his/her system. Ok.. hope this helps -Cary Steve Lelievre wrote: > > I would like to take a design made under DeltaCad, and get it cut into a > brass plate.

Re: New California DST
Politicians are idiots! How absurd for them to think that because the numbers on the clock read differently, at the same (well approx.) solar angle, that the laws of physics will change for them and somehow the people will magically use less power While they're on a roll they should work at rounding PI down to make is simpler for the school children to understand. -Cary P.S.

Re: moon shadow
Add to the fact that any moron with a computer and an excess amount of time can easily manipulate the publicly available images. My father actually helped to build the lunar lander rocket motors & Aerojet. I've seen one of the actual motors first hand. My business partner flew an ultraviolet astro camera on the Gemini, Apollo, & Skylab missions. He was inside each of the Apollo capsules before their launch. The astro camera actually went into space and photographed galaxies in the deep U.V spectrum, which does not penetrate earth's atmosphere. It's highly unlikely that millions of dollars were spent and tens of thousands of people that worked on the programs first hand were manipulated in such an manner as to pull off a hoax that even they did not know abount. -Cary Rudolf Hooijenga wrote: > > Please check out the following site: > http://www.badastronomy.com/bad/tv/foxapollo.html > > where the author has taken the time to debunk every single hoax claim.

Re: patents & copyrights
There is so much confusion about patents. There are many myths constantly circulating that just aren't true. It's not extremely expensive, the originator of the invention is the patentor (typically). There are two type of U.S. patents. etc. etc. etc If your are truly interested in learning about patents (U.S.), go get the book "Patent it yourself" by David Pressman. The "common sense" information that floats around is just totally wrong. -Cary P.S. I know these things because I wrote and acquired a patent when I was 18.

Nailed Right on the Head! You have to consider the total "fortune" you are attempting to protect with intellectual property rights legalities. Trying to protect a small niche market will just soak up your profits. It doesn't seem that there isn't very much competition in the dial market and there probably isn't millions to be made - otherwise Microsoft, Coke, GM, Ford and a few others would be peddling dials too. As mentioned before, spend your time marketing and developing your product and don't worry about cheap knock-offs being sold by Harbor Freight Tools. -Cary
