IOM Bulb Clamp

I needed to extend the fin slot on my IOM keel bulb so required a means of holding it securely while I ran the vertical mill along it. This was a quick and dirty solution which also holds it if you want to work on it manually in the vice or on the bench.
Fits a Dave Creed bulb but is probably forgiving enough in fit to hold others.
You will need suitable screws (I used woodworking ones from Screwfix) and some neoprene foam sheet (which came from a pack for children's art that I found in the supermarket). Cut the foam to fit and stick it in with double sided tape.
