How to cut in half a golf ball? We have it at TechShop.

Background:
You may be wondering "why would wonder why someone want to halve the golf ball?"   In basic, the final application is often secondary.  Is the question here, how it can be done?

Problems:
I have to keep a permanent fixture on the golf ball, so I could insert the drill holes to the LEDs display tilt switch.  The golf holding fixture worked well I had it with the MakerBot, but it is much faster way there on the Epilog laser cutter do then I glued the layers
I tried the nickel cell battery cavity milled but the router is too short and it would take days for the longer one be available.

The second attempt was laser-cutter use to deepen the slot.   After 5, the laser-cutter could make even a slight progress.   We later found that was the rubbery compound as the golf ball not for laser cutting.

The 3rd attempt is a wooden mounting wood band saw and metal of band saw use, when the teeth on the wood band saw, were too crude, and it ruined the surface to make.  If you on Metal Blade not cutting.  The ball moved and rolled.   If I support a PIN behind the golf ball to wood insert the PIN bent only.   It was a big mistake.  The challenge is that we could hit the golf ball not at its terminals, because it would jam the blade

Solution:
I approached a colleague who worked on a project with the water jet cutter.   He offered to help me cut the golf ball.   So I used the laser cutter cut a hole slightly smaller than the diameter of the ball.  I have attached a larger piece of wood and this plywood on the larger wood.  Then I stuck hole on the golf ball on the plywood perimeter.   My friend set the water jet in a cut 3-inch line pattern moving and aiming to be the golf ball on the path of the water jet.

Search results:
The golf ball can be cut in one pass with the right slow speed.   The cut edges and the surface is so smooth.

Comment:
It is unthinkable that the water jet cutter first and foremost with the 8 inch cut metal and hardwood would be same machine can halve of the golf ball so smooth and gentle way.

CNC submitted a fingerboard - TechShop on the occasion

This is the fretboard I have for my carbon fiber acoustic guitar project, part of a special event at TechShop. The fretboard is ebony with Maple, and it was on the ShopBot CNC machines at TechShop cut. The vertebrae are located in the national brands are usually placed. The first picture is the finished inlay, and the second image is the cut pieces available, which are glued together. I kept the design simple this time as it was my first time trying, inlay - but I plan to play more with him in the future.

The method to which the deposit is to create standard with Vectric V-carve Pro CAM software. Here I will show how I to make the method my deposit, but a more detailed step for-step description, see this article on the website of Vectric applied. On the last picture also see a different deposit over the first - the name of the guitar "WindSong" - you that through any other method description here is inserted.

Before I get started, I would like to say that I not experienced luthier (stringed instrument). I tried my best, to do my own research, and follow the plans for my guitar design, but only time will tell whether I was successful. If you decide to make your own guitar, please do your own research with professional guides. There are several amateur luthier communities online, and good books. I personally build your own acoustic guitar - by Jonathan Kinkead, found at my local library.

Milled guitar bridge - TechShop on the occasion

I will show in this instructable you how the bridge base for my carbon fiber acoustic guitar, with the ShopBot CNC machine and software available at TechShop made. I designed the bridge bridge of Munger is based on the signature guitars, with some minor changes. I copied the bridge slot and pinhole camera layout by another student in my workshop.  I've included that.STL 3D model mean bridge, as well as a 2D tracing the shape on the photos.

You don't need access to a CNC machine anyway, to make a beautiful bridge. I make many discussions to bridge with hand tools online and traditional routers. There are also many good books, the detailing of the traditional process of building a guitar, including bridges. Your own acoustic guitar - by Jonathan Kinkead building a book that I at my local library found, helped understand me, and was installing the bridge.
