What you need

Step 1

              Crack appears
  • Crack appears due to a stress concentration which you cannot decrease due to a strong spring at the back.

Step 2

              Cut lower part of the pinch
  • At first you need to cut the lower (moving) jaw with a saw nd file it carefully.
  • Three wooden blocks would replace the mechanism (blue arrows). You will need to keep the original upper jaw (red arrow).

Step 3

              Use a pressure screw instead of  spring
  • On the lower wooden block, drill a hole and insert a fairly large screw. It should have flat end in order not to damage the support for the lamp (generally a bed or a shelf).
  • It would be difficult to do a thread in the wood (however, you can try). I inserted a nut into the wood to provide for the threaded support.
  • Inserting the nut is very tricky. As I have no special tools, I drilled a counter bore a little smaller than the nut. Then I hammered the nut into this bore.
  • The hammering is the trickiest part. If it is too light, the nut may move eventually, if it is too hard, the wood may break.

Step 4

              The size of the blocks
  • The empty space between the upper and lower block should be a little superior to the size of the shelf where your lamp is to be placed. In my case 40mm.

Step 5

              Lamp placed on the bed structure
  • The lamp has a new system of support.
  • Tighten the screw gently to hold it in place. Do not tighten a lot, the whole system may break.

The lamp has a new system of support.

Tighten the screw gently to hold it in place. Do not tighten a lot, the whole system may break.

It is a lot of work for a lamp which costs 10 euros, but I just cannot accept to buy a new one. The lamp may otherwise shine for many years.
