Projects for a spare refractor lens

[hunterknox]

Having sold the ERF and cell from my original PST mod I'm left with the donor tube. I might try to sell it but to be honest I'm not too fussed whether it sells or not so, on the presumption I'll be keeping it, does anyone have any interesting projects ideas for an excellent 100mm Tal f10 lens?

My initial thought was to make a wooden refractor but I'm concerned about the thermal properties and humidity/collimation issues so I'm open to suggestions...

Two words: SUN GUN

Or one of this design (needs a mirror too):
