Recommendations for coil on square bottle (Johnnie Walker)

[Dan Curb]

Pretty much said it in the title... I would like recommendations on the best materials and best way to set up a coil for use on a square bottom Johnnie Walker bottle. Also any Ideas for securing a cork top bottle would also be much appreciated. Thanks for your time.

I would use two coils together, kind of like this

Thanks for the idea... any readily available source for good coils?

Check you local hardware store for screendoor springs. There are several discussions here that describe their use as replacement coils, just do a search for "spring"
