Evaluation 3 of 5

First, the author took the old sprocket on the bicycle and cut a piece of 2 teeth. He then welded into the fragment length of small diameter pipe. Thereafter, the tube walls opposite to each other have been drilled holes sized to pass through them repairable circuit.

Further, the pipe on one side leans metal plate and cut to size the pipe. In this plate is drilled hole into which the bolt is screwed.

The end of the bolt to grind sizes up to about pin connecting links of the chain.

In order to disengage the chain links, the chain must extend through the holes in the tube walls, and fix the units on the teeth. Then gently spinning bolt, pin squeeze. I think that with this tool everyone will quickly and easily disassemble the chain.

However, due to the design features of this device you will not sever links in a closed circuit. That is, its scope is limited. So I lowered the estimate to 3 points.
