Cassese Wedges

You would be forgiven for not knowing what these are.

They are infact Cassese wedges used in a machine called an "Underpinner"

The machine fires these vee shaped wedges in to the picture frame to hold it together.

A brilliant machine when it is working, mine is down waiting for the engineer to call on Thursday.

I now have time to gio and study Photoshop for a couple of hours, every cloud as they say.
