The Bottle Bit has been relaunched!

Cut the top off of a glass bottle: http://www.wikihow.com/Cut-a-Glass-Bottle
Use the Bottle Bit to sand it down and shape it smoothly and evenly.
Hi, my name is Don and I've been up-cycling bottles into drinking glasses. When I first started doing this I noticed that there are many resources out there to help cut the bottles, but when it came time to finish them off most resources just say, "Start sanding."
Cutting the bottle is only half of the project. Getting a smooth. rounded off edge is the hard part.
I thought there must be a way to spin the bottle around to make the sanding even and smooth. After much searching, I decided to make one for myself. It worked so well, I've now decided to make it for other upcycling hobbyists.
Thus, the Bottle Bit was born.
The bit itself is made from metal. It is 3 1/2 inches in diameter and will ship with a foam rubber holder (like a can koozie) to go around your bottle to hold it snugly. It will hold most standard sized bottles from 2" to 3". Standard sized wine bottles are 3" in diameter, so they fit perfectly.
After the bottle is secured in the Bottle Bit, you will then attach the bit to a hand held drill. You can either hold the drill with one hand, or secure it to a workbench while you spin the bottle and sand it down.
Along with the holder, I will ship several thin strips of foam rubber for those bottles that almost fit, but are just a little loose. You will then wrap one or two strips around the bottle to snug it up a little.
What comes in the package:
- Bottle Bit
- Foam rubber Shim (can koozie)
- 2 strips of thin foam rubber shims
How I will use the money:
I had several prototypes made by a US manufacturer. They were hand made and roughly welded together. The shop will need close to $1000 to set up the jigs and fixtures so that the production run will be straight and balanced. Each piece will then be produced at a fixed cost per piece.
The shims (can koozies) will be purchased from a manufacturer who can print a logo on them. The cost depends on the quantity purchased, but it should be around a dollar each.
The bits are fairly heavy so shipping will cost just over $6 each.
Demo of Bottle Bit:
I have asked for feedback from a number of hobbyists and experts in the area of cutting and finishing glass. Here a are a few of the helpful tips I have received:
1) There is a bench mount available http://www.amazon.com/Dico-541-41413-Switch-Drill-4-Piece/dp/B001F7AJIA that will hold your drill while you work on the bottle. This frees up your hands from holding the drill.
2) The Bottle Bit will ship with a koozie and several other pieces of foam rubber to be used a shims to hold your bottle in the bit. You can also use any other material that will hold the bottle firmly in place while it spins.
3) Please use protective eye ware and possibly respiratory protection. Very small pieces of glass will come off as you work with the bottle, which can fly off at greater speeds depending on how fast you run the drill.
4) Start with large grit sand paper or (as you can see in the video) a grinding stone. Progress to finer grain sandpaper as it gets smoother.
5) Check out my web site at www.theBottleBit.com for videos and tips. I'll be adding new information and tips often.
Risks and challenges
I'm using a professional designer and fabricator in the US to make the product, but the production will be out of my control. My plan is to have a small lot built and shipped to me so I can examine the quality. There will be costs associated with making sure the production units are strong and balanced.
If all goes well, I can then order the entire shipment.
The shims (can koozies) are made from prefabricated foam rubber. I've used several different brands and sizes, but I have to mention that I have not purchased these in bulk yet, so that is a potential risk.Learn about accountability on Kickstarter
