Laminating Is simply the building up of layers of wood one on top of the other, but you do need to apply some basic rules.

  1. Normally there must be a core or center section but not always.
  2. What ever you do to one side of the core you must do to the other side, to keep them balanced.
  3. Therefore the thickness of the laminations on each side of the core should be of equal thickness.
  4. All plys have an odd number of layers because of the above reasons.
  5. The thickness of the core can be thicker or thinner than the laminations.
  6. The thinner the laminations the smaller the radius and also the thicker the laminations the larger the radius.
Laminating can be done with various materials and in with different techniques and here are a few I have used :-

Veneers

Are made up to the thickness required. The veneers needs to be cramped into position and held there until the glue has set.

Solid

Laminations are cut on the bandsaw or better still on the table saw and are made up to the thickness required. remember do not glue up in the same order as they are cut off the log, turn over every other one. The laminations needs to be cramped into position and held there until the glue has set.

Flexible M.D.F

This is grooved out long ways or crossways (Similar to saw kerfing but in this case the hard work is done for you eg the grooving).

Only Two sheets are glue together (this forms a Core), with the grooved sides going together. The M.D.F needs to be cramped into position and held there until the glue has set.

Normally Plain (apart from the grooves) M.D.F. 6mm thick 2440mm X 1220mm

Plain M.D.F

This is Plain M.D.F in other words not faced or veneered.

Three sheets are used, and are select by the size of the radius and finished thickness required ( keep the Size under the finished size as the M.D.F will put on weight, slightly swell). Boiling water is poured over the M.D.F and the M.D.F is then cramped into position and held there until it has dried out. Normally one to two days. The work is then decramped, glued and recramped until the glue has set.

Normally Plain M.D.F. 2.5mm to12mm thick 2440mm X 1220mm.

Plain Thin M.D.F

Three or more (odd number) sheets are glue together. The M.D.F needs to be cramped into position and held there until the glue has set.

Normally 2.5 to 6mm thick 2440mm X 1220mm is suitable for most curves but it does come in thicker up sizes to 60mm but I wouldn't try laminating above 12mm thick. Good finish with thin laminations making an good choice for smooth curves as there are no hidden defects.

Birch Faced Ply

Three or more (odd number) sheets are glue together. The plywood needs to be cramped into position and held there until the glue has set.

Normally 1.5 to 9mm thick 2440mm X 1220mm is suitable for most curves but it does come thicker up to 24mm. Very small radiuses and fine finish with thin laminations making an excellent choice for strength and accurate laminating.

Flexible Plywood

A lightweight 3 ply especially produced to cater for all your bends, curves and shapes.

Only Three sheets are glue together. The Flexible Plywood needs to be cramped into position and held there until the glue has set.

Normally 3 to 16mm thick 2440mm X 1220mm. Can have a course finish.

Finishing off with Veneer

Any of the above can be finished of with a decorative veneer applied to the outside surfaces to finish off.

Finishing off with Thick Veneer

Any of the above can be finished of with a thick veneer applied to the outside surfaces to finish off. If the veneer is 3mm thick you will be able to flush off any joints etc.

Finishing off with Veneer that has a paper backing

Any of the above can be finished of with a veneer applied to the outside surfaces to finish off. The beauty of this veneer is that it comes in 2440mm X 1220mm sheets making it very useful for large areas.

Finishing off with a Real Wood Veneer Laminate

Any of the above can be finished of with a veneer applied to the outside surfaces to finish off. This is a real wood veneer applied to a plastic laminate which may or may not be pre-finished. Not for very small radiuses.

Finishing off with a Plastic Laminate

Any of the above can be finished of with a plastic laminate applied to the outside surfaces to finish off but you must remember to apply a balancer to the back. Not for very small radiuses.
