Making a tincture with alcohol

[changeofpace2014]

I want to give this a try and I have done a bit of research but I can only buy high % alcohol from the pharmacy and they will only sell it in 50ml bottles which is expensive. I have some home made fruit based spirit that my neighbour gave me but he reckons the strength is about 47%. What will happen if I use the lower % alcohol to try this?

I Seriously considered a still jut to make some high proof alcohol for oil... Came to that conclusion after paying about 65$ for a polish vodka with 170% proof.. Turned out well but too much $ for 1 run...

Sad to say some of the still parts are now being used to control a heater in the tent...
