How to Make a Boat Mold Plug

Building a boat mold is one of the initial phases in building a Boat Mold Plug. So, the interaction includes building a plug, which is an exact duplicate of the boat you want to fabricate. For small boats, similar to canoes and kayaks, the plug is frequently made from wood covered with fiberglass. Prepare the plug and then, at that point, laminate a fiberglass shell around the plug. Whenever dry, jump out the plug and finish within surface of the mold. Lay up the boat within the mold.

In this video series, we have called on composite master, Stephan Vaast to show us a cunning way to create a plug for a mold. Making a plug is the initial phase during the time spent making a fiberglass mold to assemble any number of parts and pieces. Typically, a plug is a model of the completed part, and you can even choose to involve the actual part as the plug for the mold.

There are many important steps in the mold making process, and getting the initial step of plug fabrication right is paramount to the ultimate progress of your undertaking. Vinyl Seats Boats shows us a couple of stunts for making a plug, and considering the many angles and surfaces that should be impeccably executed, he presents a great suggestion for building a part utilizing insulation foam and a cunning home assembled hot wire shaper to get amazing edges and angles off the template.

Assuming the plug contains delicate materials on its surface like Boat Mold Plug, wood, or clay, then, at that point, it should be sealed with lacquer or gum to fill the pores. In the event that plaster is utilized, it should be broiler dried and sealed.

The Mold

The initial step is to apply a gelcoat which will be the mold surface. The gelcoat should be “outside gelcoat” (wax free). Assuming many parts are to be taken off the mold, it is desirable to utilize a “tooling gelcoat” which is intended to give longer life in mold use. The gelcoat ought to be in contrasting shading to the surface of the part you will make. Since most parts are light hued, black gelcoat is generally utilized. This facilitates spraying up a uniform thickness of light hued gelcoat since the black will show through flimsy spots.

Step 1

Utilize heated glue and adhere the smaller than normal cell foam to the prepared plug along the parting plane of the Boat Mold Plug. The parting plane is where the body and deck meets. To mold the deck first, apply the foam to the body. Cover the foam with PVC tape, which stops sap from penetrating. This acts as the mold’s flange.

Step 2

Cover the plug’s deck with a light coating of sprayed PVA mold release. Cover the whole deck with two coats by first applying a light coat followed by a heavier second coat. The goal is to cover the deck with a 0.005 to 0.010 millimeter coat.

Step 3

Spray a 0.5 millimeter thick layer of tooling gelcoat over the PVA mold release. Tooling gelcoat requires a special spray firearm. John Sweet of Sweet Composites, reports a cap firearm functions admirably and requires minimal cleaning. Allow to dry according to the gelcoat’s directions. Spray a second coat of gelcoat whenever wanted.

Step 4

Support the corner between the smaller than normal cell foam and the deck by laying portions of fiberglass mat against it and the gelcoat.

Step 5

Lay 6-ounce fiberglass material over the plug’s deck and wet it via carefully brushing on polyester gum. Blend the tar according to the manufacturer’s directions. The glass should adjust to all the Boat Mold Plug. Make sure to cover the flange with this glass. Allow the gum to fix.

Step 6

Place three oz. of fiberglass mat over the fiberglass fabric and wet it with polyester pitch. Build up the flange and different areas that could flex with extra glass. Utilize five oz. of mat as the support. Allow to dry.

Step 7

Flip the plug over and eliminate the scaled down cell foam. During the fiberglass interaction, you created another flange out of glass.

Step 8

Repeat everything, except the adding of a little cell flange to create a mold of the structure.

Step 9

Separate the frame from the deck mold and pop the plug out.

Step 10

Stabilize the outside of the mold by building up it with pressed wood slice to match the mold’s bends. Each two or three feet is to the point of stabilizing it. At each pressed wood location, support the mold by applying more fiberglass mat. Cover the pressed wood edges with foam to assist with safeguarding the mold.
