There are never too many clips-))) Of course, you can buy clips in the store, but you can make them yourself, as the master did.
To make a clamp, you need a PVC coupling and a threaded rod. Of the tools a hacksaw, drill, marker.
Instead of the coupling, you can use a pipe, but the clamp will be weaker.
So, we cut the coupling across. We drill a hole. We insert the rods.
The clamp is ready.
Checking the clamp for compression showed 36, although it is not clear in which system the master measured.
If necessary, you can make the clamp even more powerful.
