Videos of Lamp Making etc
This has got quite long. It starts with videos of specific things or processes, then assembling whole lamps, and finally test procedures.
Drilling a Lamp to Take Fittings
| Here I'm drilling the top of a lamp to take the bulb holder. Normally with a new ceramic lamp I'd do this before the bisque firing, but it had dried too much and become too brittle so I decided to do it after glazing - which is much more arduous as it took 5 minutes to drill through (shortened in the video). For low fired ceramics and glass you can use a tungsten carbide bit, which must be used wet to keep it cool. But for this porcelain I need the extra cutting power of a diamond bit. This one, which has a wax core in the cylinder, can be used dry; others need to be used wet. Don't use water with a drill unless it is cordless, and so low voltage! | |

Repairing an Alabaster Table Lamp
This is an old alabaster table lamp that had had a fall and broken the bulb holder. Here I disassemble it, showing its construction using Allthread, and replace components to make it as good as new again.
Rewiring Table Lamps

Making a Lamp from a Vase Using a Bung Fitting
| This is a porcelain vase made by Bridget Drakeford that I wanted to convert into a lamp, but with the possibility of turning it back into a vase at a later date. So I used a bung fitting in the mouth of the vase, with a side entry tube allowing the cable to enter and go into the base of the light fitting. As it is likely to be used as a desk lamp, I used a bayonet bulb holder to enable the switch to be in the bulb holder. | |
Making a Lamp with a Dimmer switch and Edison lightbulb
| Using a ceramic base with a riser, a dimmer switch on the cord, and an Edison bulb holder. | |

| Taking us through how he made some table lamps using a wooden base. | |
Continuity Testing
| This is on the most basic of lamps, using a metal bayonet bulb holder incorporating the switch. This is the first test that should be done to any lamp. You test all possible combinations of connections, so that you know all intended connections have been made, and no unintended connections have been made. For more complex designs, it can be worth making a test sheet, showing all connection combinations to be done, and the required outcome. | |
Class I Lamp Production Electrical Tests - 1
| This is on the most basic of lamps, using a metal bayonet bulb holder incorporating the switch. Showing you the earth continuity and insulator resistance tests, done after the continuity test. After these, you know the lamp is safe, so you can then test that it works properly. | |
Class I Lamp Production Electrical Tests - 2
| This lamp has a dimmer switch in the cord, and an Edison bulb holder. Showing you the continuity/polarity test, earth continuity, insulation and earth current tests - the latter is normally just used in type testing. | |
