How to repair a car tire. Making a cheap tool for cutting tread

If your car or motorcycle tires are worn out, you can manually retread them with a very easy-to-make tool. This will save you a lot of money by extending the life of your old set of tires.

What you will need:

• wooden strip or block;
  
• safety razor blades;
  
• clamps with a worm mechanism – 2 pcs.

Tool making process

The lath or block must be planed so that the workpiece fits comfortably in the hand. One of its ends must be rounded to fit the diameter of the clamps.


It will also need to be split lengthwise in two places.

2 clamps are pulled onto the workpiece. Then you need to divide the blade into 2 halves and bend one of them into an arc.


Its ends are inserted into the crevices at the end of the wooden handle, and the clamps are tightened.

Now with this tool you can cut the tread along the old worn out contour. Its depth is regulated by the reach of the blade.
