There is quite a lot of methods to make a bottle neck guitar slide. Some using a rope blow torch and a hammer. Knowing me Id probably end up hurting myself or burning the house down.
Saw this video on Youtube
In short you need
- Wine Bottle
- Wine Bottle Cutter
- Hot and Cold Water
Score the bottle with your cutter. Heat up with hot water run under cold tap. Repeat that and the score line should crack leaving you with a smooth cut needing sanding.
Im going to try this tomorrow.
Ive tried using 2 beer bottles and a wine bottle.
Glass Cutter for £2.99 to score beer bottles then just used hot water and then cold water.
Needed a pipe cutter for the wine bottle which was a lot thicker.
