cutting bottles

I have been trying to cut the ends off the vinegar bottles that I buy in sains or asda.
There are at least 10 every couple of months because that is the cheapest way to buy a gallon of vinegar.
I do try to put them in the recycling bin but they take up a lot of bin space and weigh the plastic kitchen bin bag down.

I tried to cut a straight line using a glass cutter but it is almost impossible to get it straight and steady.
Next I looked online for glass cutting comments.
There was a very interesting utube video about using hot and cold water to separate your scored bottle.

Then I found a home made jig on Instructables and that is what I made this morning.
My jig is an old shelf we had lying around in the shed and I already had the screws and the glass cutter so the whole thing was free.

Hmm, it is easier said than done though , cutting a bottle.
I dont know if my cutter is a cheapo thing or blunt but it was difficult to get a continuous scored line even using the jig that holds the bottle perfectly.

My endevours so far have resulted in various wobbly edged glass shapes.
I want them for mini garden cloches as they are glass and wont blow away.
The plants wont care about the edges being wobbly but my eye is offended just the same.

I shall persevere!

I love instructables and today while looking for the instructions for the jig, I decided to use some of my surveys money to buy a pro membership. I can download their instructables as pdfs then or download their ebooks which are compilations of various things.

2 years membership is about £24 so very good value when you think of all the info that I find on there.
