The wire 2mm I used was only just strong enough for this so I'd use 2.5mm or even 3mm wire if I made these again. The front guard is perfect but the back one rattles a little.
I've entered this into the inner tube reuse contest so don't forget to have a look at all of the entries and vote for your favourite ones, when the time comes.
Here's what you'll need :
- Steel wire 2.5mm - 3mm (if using 3mm wire, a small amount 2mm wire will be better for the cross pieces)
- Scrap steel sheet about 1mm thick
- Old inner tube (thick MTB tube is best)
- Washers to suite the bolts
- Leather punch
- Eyelet tool
- Allen keys to suit bike
