Simple Bamboo Lamp Shades (wall & hang)

Featured

Step 2: Cut them

BEWARE: Bamboo splits and edges can be razor sharp!

This step wont need much explanation..
Just remember to plan your cuts. You'll need to check first where you want to cut to make sure you get nice pieces out of it and less waste as possible. It's better to cut them in slightly different lengths but ending up with nice pieces than precise lengths but not so nice pieces. They'll hang separately so no one will ever see the different lengths anyway.. 

I forgot to take picture of this step, I hope the illustrations and explanations will be clear enough

The first picture illustrate my "planning" for the pieces. Mark 'em and cut 'em up!
It's not easy to cut big bamboo straight, especially with a handsaw..
In the pictures of the final product you can see that I'm not very good with my handsaw.. but hey, that'll do.. 

Joint walls can be easily broken by hammering or using the chisel, then you can smoothen it using a sharp knive. for the wall ones, I'd do smoothen them after cutting the sides. (Pic#2: joint wall still in place. Pic.#3 shows my result, smooth enough for me..)

For the simple hanging one, It' a full tube closure, the cutting ends here. That piece can go to next step.

For the wall-mount shades, you'll need to cut the bamboo along one side (off-centred) that will be touching the house wall. Choose the part you want to show and cut in the other side of that. (see Pic.#4)
The easiest way to cut bamboo along the length is to make a crack and split it down. In this case you'd want to make both cracks simultaneously to prevent uncontrolled crack. 
I used a big knife and a hammer to help me sink the knife down, when it's a third way down I was able to twist the knife and the cracks followed a straight line down.
AGAIN: careful with the edges! they can be very sharp. Use the knife to round the edges and joint walls..

Modification to one shade
As the shades are completely opaque, they were great for my decorative wall lamps and on top of the dining table where I only need the down light on the table. There's also some light coming out from the hole on top which reflects on the ceiling and gives a dimmed glow in the room which are perfect for the bed room and dining table.
The problem comes with the kitchen light, it's too dark to work with the same style of shades. I need to modified that one.
Pic.#5 (last pic) is the solution to my problem. Again - sorry for not taking pictures of the process.

Here's how I did the cuts:
I made cracks with my knife and hammer, two cracks at a time (like the wall shades) but this the knife is positioned in the centre of the circle, and only to a certain length, NOT all the way down. 
The Joint helps prevent the crack going all the way down, I dont think you can do this trick on a joint-less piece.
For my 'design', I needed 8 "teeth" so I made 16 cracks, or 8 times knife-and-hammer trick.
The latitude cut (is that a correct term?) was the trickiest one for me since I don't have any power-toys, oh, i mean power-tools, except for my dear drill.. So I made several holes slightly lower than my cut line. Perpendicular and sideways holes, criss-crossing to weaken the tooth, carefully not to touch the other "teeth". Then snap it off, followed by some knife work to make a straight cut.
