With a simple home-made universal wrench, which is made of hand-held clamping pliers and a piece of a motorcycle chain, you can unscrew the nuts of different diameters.
Such a universal chain key is useful in the garage and home workshop. And to make it very simple. Of the tools you need a grinder and a drill. But, of course, it is better to use a drilling machine to drill holes.
The first step is to drill a hole in the clamping jaw sponge. The hole itself is necessary so that a chain lock can be installed. Therefore, its diameter should correspond to the diameter of the pin on the chain lock.
The main stages of work
Next, you will need to make a small semicircular groove on the second clamping jaw sponge. A chain will be inserted into it.
At the next stage, in the previously drilled hole, it will be necessary to install a lock to which the end of the chain is attached. The second end of the chain is inserted into the groove in the second sponge. Such a simple construction.
Then the master welds a piece of metal bar to the fixing screw. The result is a collar - this is needed more for convenience. Therefore, if there is no desire, then you can not do this operation.
