DIY wood hood

Greetings, Samodelkins!
From this article you will learn how the author of the YouTube channel “Likhoy Topor” managed to bring to life a very interesting idea: the hood, which is completely lined with natural wood. The hood, by the way, is from BMW in the back of E30, which is rightfully considered a classic.
 DIY wood hood  DIY wood hood And no, this is not a film, this is a natural American walnut. The creative process, as always, was accompanied by a bunch of difficulties and experiments, but in the end the master still managed to achieve the intended result.
 DIY wood hood In order to sheathe the hood with wood, you first need to make it. It was decided to make it from fiberglass. Step one: rub the matrix with wax.
DIY wood hood Here you also need to know the subtleties. First, the wax must be applied evenly, and then rubbed until all stains are completely gone.
The next step, already on the waxed matrix, is applied a gelcoat (this is something like a primer), thanks to which the front side will turn out to be even and almost immediately ready for painting (in this case, for veneering, but more on that later).
DIY wood hood DIY wood hood Such fiberglass hoods are most often made in two parts, and each part is made separately. It is for this very reason that the author uses two matrices.
DIY wood hood DIY wood hood We are waiting for the gelcoat to dry completely and proceed to the next stage – we dilute the polyester resin. There is nothing complicated here, you just need to thoroughly mix both components, and then evenly apply the composition with a roller as much as possible.
 DIY wood hood  DIY wood hood Then we put glass mat and thoroughly impregnate it with the same polyester resin. This is exactly the layer that will give the rigidity of the future structure. Since the fibers are impregnated with resin, after hardening, a very strong, but at the same time, rather light construction is obtained. That is why such details are used in tuning, when it is necessary to lighten the body, plus everything such a hood will never rot.
 DIY wood hood In order to spread the glass mat as evenly as possible and get rid of all air pockets, such a roller with thin metal needles is used:
 DIY wood hood Thus, we put on 2 layers of glass mat with a density of 150 first and 450 second layer (this density speaks of grams per square meter).
Then we proceed to the second component. To do this, add Aerosil (colloidal silicon dioxide) to the resin. Thanks to it, the resin becomes thicker.
DIY wood hood After that we apply it to the future stiffeners. Here is the same scheme: gelcoat, resin and glass mat.
We leave the blanks for a day until complete polymerization.
The next day you can take the blanks out of the dies. The images below clearly show what the gelcoat is for.
DIY wood hood DIY wood hood  DIY wood hood As a result, the surface turned out to be almost perfect, of course, provided that the matrix was initially flawless, since this composition is able to make an exact copy of your surface, and, accordingly, all the flaws, if any.
So, at this stage we have 2 matrices that will need to be connected to each other. But first you need to get rid of unnecessary elements and cut off all unnecessary ones. It is at this stage that the hood is already beginning to take on its original shape and becomes generally similar to the hood.
DIY wood hood In the future, all these ends will have to be brought to the ideal manually. To connect the two parts, use the matrix again. She helps a lot with positioning and as a result, it is simply impossible to miss. We put mortgages in the hinge attachment points.
It's time to put the two hood parts together. For this purpose, we will use a filler. This is a special composition created precisely for such tasks. In other words, it's kind of like glue.
 DIY wood hood Here's a little life hack for you: put the composition in an old silicone tube using the most ordinary spoon, put a cork and use the usual method, which makes application very easy.
 DIY wood hood DIY wood hood Apply a filler around the perimeter of the blanks and connect two matrices, additionally tightening them together with bolts.
DIY wood hood We leave the hood alone until the next day, after which, making sure that the composition is grabbed, we disassemble this sandwich.
 DIY wood hood At this stage, we have an almost ready-made hood, which can be painted almost immediately, well, or not painted, as in this case. All that remains is to grind the ends to remove excess glue.
 DIY wood hood But let me remind you that the main idea is not to make the hood, but to veneer it with natural wood. It is for this reason that the master turns out to be 300 km away from home in order to personally select a couple of veneer strips.
 DIY wood hood This is really important, since each sheet is individual and very different from each other in pattern. It took quite a lot of time to choose the appropriate option, and in the end the author settled on the American nut. We managed to choose specimens with a very large and expressive pattern, in general, the day was not wasted.
At this stage, we will start making a canvas that will completely cover the bonnet area. To do this, the first step is to glue the sheets together.
In order to evenly press such a healthy veneer sheet, it was decided to use a vacuum. In this case, it is a homemade vacuum made of cellophane and sticks. Cut off a suitable piece and put the hood in the bag.
 DIY wood hood It is clear that no one particularly veneered the hood and we could not find detailed instructions on the network, so we will experiment. First, we put the veneer on the hood on a dry one, in order to understand whether it will be possible to evenly press it to the hood.
Then we glue the film around the perimeter with a special seal.
DIY wood hood This seal is self-adhesive, which will create an airtight connection.
We put a tube inside, with which we will evacuate air and connect the compressor. In this case, this is a compressor from a refrigerator.
DIY wood hood And everything seemed to work in general, but of course it did not do without jambs, everything worked too well, and the front part of the hood caved in.
DIY wood hood So let's do one more experiment. We redo everything over a new one, but this time we cut the bag in order to create a vacuum only on the front side.
DIY wood hood Testing for dry again and now everything is fine, so you can do the same, but with glue.
It was decided to glue the veneer to the hood using polyester resin. It dries pretty quickly, we mix the composition.
DIY wood hood Apply resin to the hood surface, put veneer on it, and film on top of the veneer.
 DIY wood hood As a result, everything worked perfectly, the film presses the veneer over the entire area.
 DIY wood hood After a few hours, you can remove the film, the resin has set and in general everything looks pretty good. There are, of course, small nuances that can be avoided only with experience, but the technology is generally working.
 DIY wood hood The next step is to grind the ejected resin and then you can proceed to the final coating.
 DIY wood hood At this stage it is necessary to degrease the hood from all sides.
DIY wood hood It was decided to paint the interior in black universal color.
 DIY wood hood We will paint the front side with glossy varnish.
DIY wood hood After a few layers and a couple of days of drying, we proceed to the most interesting thing – we go to a place where there are many BMWs in the back of E30 in order to try on a unique hood.
