Vacuum Forming Versus Bending

The two most common methods used in the lamination of wood are the more recent vacuum forming, and the traditional method of bending the laminates around a former with the use of cramps.

Vacuum forming is where the glued laminates and the former are placed together in position in an airtight rubber bag.The air is then removed from the bag, forcing the laminates to conform to the desired shape.

The advantage of this method is that even pressure is maintained all round. One of the disadvantages is that any movement occurring inside the bag during the process cannot be seen from the outside.

Everything must, therefore, be in place and unlikely to move before the vacuum is created.

I have had good results using this method on smaller laminating projects, but in this instance I decided to use theTage Frid method of clamping the laminates to the former, see main text
