For this homemade product you will need a small soldering iron with a capacity of about 60 W, as well as a piece of a blade from a stationery knife and an M5 screw. Homemade knife for hot cutting is widely used in the process of manufacturing various DIY crafts.
In particular, it is very convenient for them to cut ribbons and fabric, while the edges are smooth and fused. You can also cut plastic, polystyrene and plastic bottles with a thermal knife.
Moreover, to make a homemade knife for hot cutting, you do not have to violate the factory design of the soldering iron. It will take literally 5-10 minutes to remake it into a hot knife. If interested, then read on!
The main stages of work
First of all, unscrew the fixing screws at the end of the soldering iron and remove the "tip". Then we take a bolt or screw M5, clamp it in a vice and cut it along about halfway to the middle with a metal hacksaw.
Then, one segment must be broken off from a standard clerical knife blade. The bolt is inserted into the file, and a broken segment of the blade is inserted into the slot. We press the elements with fixing screws.
Now turn on the soldering iron, wait until the blade heats up with the bolt, after which you can proceed to thermal cutting of plastic, fabric or other materials. The process of manufacturing and assembling a knife for hot cutting can be viewed in the video on the site.
