Materials:
- welding electrodes 2-3 mm;
- PET bottles;
- ear sticks;
- bicycle camera.
Template making process
To make a template, you need many straight rods of steel wire. Welding electrodes stripped of coating are ideal for this.
You need to cut them in half and process them from the ends so that they do not have sharp corners.
You need to wrap paper on a piece of pipe of the same diameter for which the welding template is made. Then the cut-off central part of the PET bottle is put on top and shrinked with a hairdryer. After shrinking, the resulting plastic tube is removed.
A wide ring from a bicycle inner tube is pulled onto a steel pipe. This is necessary to drag it onto the plastic tube.
After this, steel rods are inserted under the elastic around the entire circumference. The gaps between them are filled with plastic tubes from ear sticks.
The resulting structure is placed on a steel pipe, and another middle of a plastic bottle needs to be placed on top of it with a hairdryer.
After this, the template can be placed in place and the rods can be pulled out of the body until it stops, which will allow it to take the shape of the end of the welding tube. Next, it is put on the workpiece, and markings are made on it.
The part cut in this way will fit perfectly.
