1. These tools will be used to cut the tubing and finish the ends. Details of this procedure can be found here.

2. These are used for punching holes in the lampshades. This procedure can be reviewed by clicking here.

3. Bending of tubing using external support can be easily performed by using a bolt's threads for side-support during bending, similar to the way a conduit bender works. Click here for details.

4. Flaring of tube end is for lampshade support and bonding. This procedure can be reviewed here.

5. Two-part epoxy is preferred over CA adhesive for affixing lampshades to tubing. This procedure can be reviewed here

6. This soldering iron is used for pretinning the N5038 magnet wire (included in kit). This procedure can be reviewed here.

7. A low-temperature iron is used to solder the wires to the LEDs. This procedure can be reviewed here.
