Right then, bit of an odd questions:

I purchased an Alpa style shutter button, like this:


To used on my Graflex XL. It does not fit, far too loose, the thread of the shutter button rattles around in the Graflex.

So basically, other than glue, or maybe building up the thread to accept the Alpa shutter release, is there any other type of 'thread expander' I can use?
