I’m sure you’ve all heard that horrible noise you get when you put a sheet of metal upright in a vice and try to saw through it.
The noise is cause by the sheet vibrating as it’s cut. As well as the noise there’s a few other issues with this approach. Firstly the metal is not very well supported so could buckle or twist as you are cutting it. It’s also not very easy to keep the line straight.
If you put the metal further down in the vice it provides more support and you’ll not have the squeaking or buckling. However it does mean that you’d need to keep adjusting it if you had a long cut to make.
So the solution is to clamp it differently. You can clamp the sheet to the bench with a batten. The longer the distance the stiffer the plank you will need. Ensure you position the clamps to avoid clashing with the saw. You also need to ensure that it is secure and won’t move. This approach means that your metal is better supported so does not buckle or whine. The cut should also be straighter as there is more of the saw blade in the slot so it follows the same line as already cut.
There is another advantage which is the shallower cutting angle means that there are more teeth cutting on each stroke. This means you should complete the cut faster and with less effort. This should make up for the extra setup time.
So remember when cutting sheet metal with a hacksaw.
- Secure clamping
- Supported work
- Leads to straight cuts
I’d not actually done much research into if anyone else had already done built a weather house similar to the Enchanted Cottage project. Following the project I had a check and it turned out that there is at least one
Today was the final day for any submissions to the Enchanted Objects Design Challenge. As well as completing our projects we were tasked with blogging about the challenge on the community website, hence why you’ve not heard more about it
For the Enchanted Cottage project I wanted some spacers for between the Arduino Yún and the shields so that it would be securely mounted on the chassis. There’s not a lot of space so I designed some in OpenSCAD with
This book endeavours to teach you what they don’t teach on an electronics degree, the process of turning your prototype circuit into a product. It does so by selecting four key topics; design issues, design for manufacture, compliance and project
I do like working with a wide range of materials but there’s a few that I don’t know that much about. One that I’d like to experiment with a bit more is concrete. Priority Plant a top tools manufacturer to
A few years back we were given a pair of decorative birds for the garden. Before too long, the small one’s legs became detached and more recently the head of the larger one has come off. When you look at
My old Antex soldering iron is about 25 years old and although it provides a good service it is a bit beaten up. The cable is held together with self amalgamating tape and the element is looking a bit corroded.
