I cut a square hole into a couple of stacked 3/4 inch squares of plywood. You could use a block of nice wood instead. Now my square bottle of head cement cannot tip over plus you can unscrew and screw the lid on and off easily with one hand. Your glue is always right in front of you where you need it. Its obvious that I am no carpenter. But you can see from the picture what I mean.

Ps Before i found the square bottle I had a round one. Its even easier , you get the proper sized drill bit , drill it to the same size as your bottle . as you start the bottle into the hole place one of those thin toothpicks along one side of it to jam it snugly in the hole for one handed operation of the cap.
