Wine bottle cutting jig

I tried my own version of a wine bottle adjustable cutting jig.

First you need one of these glass cutter. I found mine on amazon for about 6 $

Then just cut a 45 degree angle on a piece of  plywood

Break the handle from the glass cutter and determine
where you will position it so only the cutting wheel sticks
out from the plywood. Trace the shape with a pencil.

Trace the shape again on another piece
of wood or MDF (same thickness as the cutter).
 Cut this piece with a band saw and use the traced shape to
determine exactly where to glue it . You can double check by
repositioning the cutter and make sure it fits tight.

You can now screw it in place and it wont move. If you
wish to change the cutting wheel, it's easy to do so.

Next step is to make something to hold the neck
of the bottle while it turns. Place a bottle in the previous
plywood piece and find the height of the center axle.
You can now report it to this piece and drill a hole for the
neck (in my case it was 1 1/4 "). Screw or glue another piece
perpendicularly to this one (see next picture).

Then we want to assemble a bridge than will slide over the bottom part.

                Glue the cutting board to the bridge. I added a backing for support.        

Make a groove int the center line for the adjusting bolt in the center,
 and drill a matching hole in the bridge.

I had access to a router for another groove to clear the head of the bolt.
 I suppose you could also add feet to the jig to allow clearance.
