Boat Fiberglass Tabbing

I’ve seen several fiberglass subwoofer guides that show how to make a custom fiberglass sub box. None of these guides have actually really explained just how precisely to do it. Either they don’t have enough photos or do not discuss it correctly. In this guide I am going to give you the In’s and also Out’s of Making a custom-made fiberglass speaker box. I have actually made a decision to make a below box for my Honda Prelude. I am going to be mounting a JL Sound W3V3 with a 500 watt Towering Amplifier.

Personalized Fiberglass Subwoofer Box:


1 Gallon of Fiberglass Resin (discover at Vehicle Area, Advanced Automobile Components, And So On).

Affordable Paint Brushes (possibly about 10; you will certainly discard after each usage).

Rubber Gloves for fiberglassing.

Fiberglass mat (about 6-8 packages depending upon the size of your box).

MDF Timber 1/2?

2 Dowel Rods.

2 Rolls of Masking Tape.

Aluminum Aluminum foil.

Low-cost Blending Cups.

1-2 sq backyards of fleece (hobby lobby).

Fiberglass Sub Box:.

Ok, time to start making a fiberglass below box! The initial step to making package is drawing out some plans on what you want as well as exactly how to you want to do it. When fiberglassing, you can not really repair your errors due to the fact that when fiberglass resin is completely dry, its DRY.

We wished to make a straightforward box that would save space, as well as look oem to the start. We started by laying masking tape down so no fiberglass resin gets on the rug, due to the fact that if it does, its destroyed. Also, ensure to tape extra area after that your actually mosting likely to use just to be secure.

We did regarding 2-3 layers of tape and afterwards also included some aluminum foil as a layer, as to not get any type of glass on the carpet. When you believe that you have enough tape and also there is no possible manner in which any longer fiberglass might get across the carpeting; do one more layer.

The next step after you have tapped whatever is to start fiberglassing. Prior to you blend your fiberglass with your hardener, you must reduce strips out of your fiberglass floor covering. I normally make strips concerning 7-9 inches vast. When you prepare, what you need to do is blend your fiberglass with your hardener in the mixing cup. The hardener will certainly have how much fiberglass resin to hardener mix to make. Make sure you prepare before you begin fiberglassing because it dries somewhat quick. Paint a layer of fiberglass resin onto the tape without any mat. After you have actually repainted a layer put fiberglass mat down and repaint one more layer over fiberglass afterwards. Wait regarding 10 mins and afterwards do one more layer prior to it dries totally.

Currently, wait a minimum of an hour and let the fiberglass material completely dry. When its completely dry, you can take the mold and mildew out and also detach all the tape and also aluminum foil. Put it back in your trunk and also draw out where you want to cut off. Ensure you go gradually and do not take all of it off simultaneously.

Currently you require to remove a MDF ring for your speaker to screw right into. Some choose to make a flush ring with a router however I such as the one ring means much better. I am using a 10 inch jl audio w3 so I cut out a 10 inch ring as well as utilized the specs from the box to make a ring the right dimension.

Then we took out our newly trimmed fiberglass box and also placed one more layer of fiberglass mat on it. Usually you wish to do 原理原則のコンテンツseo regarding 5-6 layers of fiberglass. Some claim you must be able to base on your box without it breaking. One more great fiberglassing tip is to remove as many air bubbles as possible. This will certainly make the mold and mildew a whole lot stronger because there’s no air pockets. You do this by stabbing the fiberglass rather than actually trying to repaint it.

Ok, enough playing around; back to fiberglassing! Next we placed on a last layer of fiberglass floor covering and also resin. Hereafter has totally dried out (concerning 3 hours) we started sanding and reducing to obtain the form we desired with our custom-made fiberglass below box.

When your back mold looks great to you its time to set your MDF ring up exactly how to want your sub to be. Hold your ring up where you believe you would like it. Cut some dowel poles to dimension and also position your ring how you desire it. We utilized superglue and epoxy to maintain the dowel rods as well as the MDF ring in area. Its important that your ring is very strong and also tough because we are going to extend fleece over it.

Ensure that when your ring remains in location every angle looks great and also to you. When you stretch the fiberglass as well as begin painting resin on it, there’s no reversing.

Currently is the enjoyable part. This is where your fiberglass subwoofer box starts ahead with each other. Get your fleece as well as stretch it over your mold you have made. Be sure to stretch it as limited as possible so there are no folds or loose parts. The fleece ought to be touching every side of the rear of the fiberglass mold and mildew.

Make use of a staple weapon to protect the fleece to the subwoofer fiberglass mold. Staple the staples in the side of the fiberglass box so you don’t fiberglass over them and also have them be stuck forever.

As soon as you assume its done appearance it over once more from all side as well as ensure it looks exactly how you desire it to look because when the fiberglass resin gets on, its that form for life.

When whatever looks great to go, its time to start glassing. Mix an excellent amount of fiberglass (concerning 12 oz) and paint the fiberglass over the fleece. Paint it on thick, and also see to it to go all the way to the edge so you mold the two pieces (front and back) with each other. There’s no demand to repaint the whole ring due to the fact that we are going to cut it out anyway. Do fiberglass the fleece to the MDF ring.

Once its completely dry (took around an hour since we made use of a lot of glass) you can cut off the gain access to fleece from the edge of the mold as well as around the ring. At this time you ought to have the ability to pull the dowel rods out of the box as well as the ring should remain where it is. Once you’ve trimmed off the bulk unwanted of the fleece, throw the box in your auto and see how it looks. Looks respectable right here!

Not to screw up the external form of our fiberglass sub box, we need to include the rest of our fiberglass layers to the within package. Add regarding 2-3 layers of fiberglass mat to the inside of the mold. Make certain to fiberglass in between where both molds integrated.

Once you end up the within package venture out the sander as well as the jig saw as well as removed all the excess crap around your fiberglass box. We are going to use carpet on our box, so we do not require to sand the really fiberglass mold. Rather we just sand all the edges as well as edges so it fits snug right into the trunk of the Honda Overture.
