How to Make a Wood Mold to Lay Fiberglass Over

Making a copy of an object requires a mold. Depending on the size of the mold, you may need to use a wood frame. If a two-part mold is required, a parting board will be needed. You can make wood frames or a parting board from plywood or other scrap wood. To do this, the proper measurements of the object for the mold will be required.

Things You'll Need

Tape measure
Plywood
Circular saw
Jigsaw
Table saw
Wood glue

Instructions

Cutting a Frame
- 1
  Measure the width and height of the object you need to mold with fiberglass with a tape measure.
- 2
  Transfer the measurement to a piece of plywood and draw an outline by using a pencil.
- 3
  Drill a hole at each corner of the outline with the power drill. Insert the blade of the jigsaw into a hole and cut along the outline.
- 4
  Place the plywood mold over the object.
Making a Parting Board
- 5
  Measure the height of the object with the tape measure. Note the height on a piece of paper.
- 6
  Transfer the width to two pieces of scrap wood. Cut the wood to the height of the object with the table saw.
- 7
  Measure the width of the two pieces and add this measurement to the width in Step 1. Cut a second piece of scrap wood to this width.
- 8
  Apply wood glue to the top edges of the two pieces you cut in Step 2. Glue these pieces to the bottom of the larger piece in Step 3 with wood glue to make a "U" shape.
- 9
  Place the parting board over the object.
