What you need to know about clamps
- Screwing – as is the case with C-clamps, tightening or loosening a screw adjusts the opening of the clamp.
- Striking - think of mason clamps, which are hammered down into the substrate beneath the masonry to secure it.
- Squeezing – most hand clamps can be done ‘one-handed’ either using a spring or a ratchet system to apply pressure.
A few words about the main clamps
- The spring clamp: these will meet about 40% of the needs by themselves. It is the most robust and powerful variety. The spring, which provides the force to the clamp, is usually completely protected from blows or dirt. Look for models with sturdy metal handles, as this will extend the lifespan of your clamp. Longer handles are also an advantage as they allow for easier use or for high clamping force. These clamps are perfect for glueing or fixing an assembly of parts.
- The screw clamp: a little less elaborate and less powerful. Tightening or loosening a screw adjusts the opening or the force of the clamp. The clamping force of these models is only actually limited by the strength of your arm.
- The masonry clamp: as indispensable to the mason as the wheelbarrow. Tightening is carried out by striking the slide which moves along a steel rail.
- The "one hand" or hand-pump clamp: as the name indicates, it can be operated with one hand. The hand pump operates a ratcheting system which tightens one side of the clamp. These models are limited in their power (roughly a hundred kg).

After having installed loft isolation, and having refurbished the bathroom, the toilets, the kitchen, the bedrooms… I built an extension, installed a new fence with a gate and kitted out the house with a solar panel to make hot water. I have poured tens of tonnes of concrete into slabs or into the foundations and renovated the roof… I can say that building materials and tools are no stranger to me!
If I had a pound for every hour spent looking up information in forums and DIY magazines to find solutions to my problems, I'd be a millionaire! So passing on my knowledge on tools and home equipment is natural, as it is just giving back what I borrowed.
