Thanks much, I appreciate all the positive feedback from this project. Even though the quality of technical writing was probably from somewhere between the design news editors and spellcheck, not any specific skill on my part.
I would definately agree that a synthetic material or metal would make a much sturdier device, though as it is now, the mill itself would not be able to mill aluminum, or anything beyond hard woods with any accuracy or speed. Plastics might work, but it would probably be better to use another mill designed for greater precision or strength, as this design was only used because it is very easy to make using only the tools in my schools woodshop. Something smaller, and some type of linear bearings would probably keep everything from bending and turning as much as it does now.
Thanks for the comment, 78rpm. I'm sure John will apprecaite it. As for editing, John's submission required very little editing. This is one of the best Gadget Freak submissions by anybody, and I've seen them all from the start.
I agree, 78RPM. This author is an amazing inventor, regardless of age. His past inventions, an LED flashlight and LED lantern, were equally impressive. I agree with you -- he could have a great future in engineering, and the engineering profession would be glad to have him.
I've read a lot of Gadget Freak projects in the past couple of years and this is about as impressive and as useful as any of them. It's hard to believe this comes from a teen inventor. He has a bright future in engineering. I was also impressed with the quality of technical writing. I'm not sure if he had a good proof reader or editor, but the writing was flawless upon my first reading, and I'm usually quick to pick up typos, grammar, spelling, and punctuation errors. So many technical articles look like they were written by someone for whom English was a second language.
I might actually try to build this project myself. I might consider other materials than wood, e.g., Corian® or aluminum. Hey, how about making a wood version for the first cut and using it to make a second version of itself for the Corian or aluminum version?
Nice use of an encoder. Good mathematics knowledge for a teenager.
At this year's MD&M West show, lots of material suppliers are talking about new formulations for wearables and things that stick to the skin, whether it's adhesives, wound dressings, skin patches and other drug delivery devices, or medical electronics.
The US Congress has extended an important tax credit for solar energy, a move that’s good news for future investments in this type of alternative energy and for many stakeholders in the solar industry.
