Hi Guys,
Many times I have had to clamp something but unable to get the angle I wanted.
So I have come up with this idea.
I don't know if it Will work as I have not got anything to make it with at the moment.
The idea is you make a frame around the object using different length pieces of frame at different angles and tighten the frame using bolts and wing nuts tightly.
Then use a long bolt to clamp the object.

Using a combination of lengths , bolt holes ,and angles it should be possible to clamp most things. Hopefully.
