A Hot-Wire Cutter With Inbuilt Heat Controller

6 Dec, 2010

If you've ever tried to cut polystyrene (especially!) and polyurethane materials using a saw, razor blade or knife, you'll know that the results are invariably less than satisfactory.

The hot wire actually melts the material and results in a very neat, very fine cut, without the thousands of bits of foam flakes you normally get.

Recycle Your Cordless Drill - Make It Corded

8 Dec, 2010

Handyman cordless drills are very cheap - most readers probably have at least one or two in their tool collection. But their big weakness is the battery pack and associated charger. What do you do when the battery pack dies? Just convert the drill to corded operation. It's a simple conversion and ideal for working close to 12V power.
