DIY vulcan fiber spacers are a way to create some elements yourself that you put on the knife.
It is more a personal satisfaction than a necessity given the low cost of these elements that you put on the knife
If you read the blog you know how I like it by personal choice i make many tools and materials alone.
I’m a fan of DIY (acronym for Do It Yourself,equivalent to the Italian DIY)
This I propose is a way to make spacers made of volcanic fiber in different colors alone and with little equipment.
Volcanic fiber is a laminate composed only of cellulose.
The material is hard, durable (in the original: resilient), horn-like, lighter than aluminum, harder than leather, and stiffer than most thermoplastics.
A layer of volcanic fiber rolling is used to strengthen the wooden sheets used in skis, skateboards, supporting beams and as a sub-laminate in thin wood veneers.
Now it also finds application in the knife as an aesthetic because it is a material that:
- you don’t compress much,
- glue adheres to it well,
- you can sand,
- has good dimensional stability,
- it doesn’t crack or divide or shrink.
So it’s a material compatible with all the cutting and grinding you do when you build a knife handle:
- doesn’t break under UV light,
- resists reasonable levels of heat,
- does not react to chemicals that can damage a knife handle while using it,
- it’s water resistant completely,
- available in various colors
- you’ll find it of different thicknesses
Today there are also plastic but the aesthetic effect is less warm and with different characteristics.
I personally prefer those in vulcanized fiber!
The first part is the shopping list and the second part is how to use the shopping with the recipe to make the vulcan fiber Diy from you.
- Quality colored cardboard (red, green, blue, white, yellow, black, pink, etc.)
- Bi-component resin
- Latex gloves and protective mask
- 2 plates made of aluminum or thick wood or other material
- Plumbing press or other method (carpenter’s clamps/miscellaneous clamps/etc.) to press sheets filled with resin
- Baking paper sheets
Ps. Always put on two gloves so that when you’re done with the resin you take off your first glove and underneath you already have the clean one!
Now repeat the operation until you reach the thickness you want to get.
Now close with the resin layer at the top and close with the parcher paper.
Wrap everything with baking paper to prevent the pressed resin from escaping by going to dirty tablets and press, etc.
Ps. You do the same thing when you do micartas
Put between two wooden or aluminum tablets and close well with clamps/biters or if you have an even better hydraulic press.
Pss. If you put a lot of sheets you made a plate of micarta.
I only use epoxy, but they tell me that polyester can be fine too (I have never tried).
Attention! The original one has a different process!
Industrial production of volcanic fibre
Making the industrially volcanic fiber is a process.
Volcanic fiber is composed of layers of paper.
Over 99 of the finished product is made of cellulose, so the volcanic fiber, although not made of paper, is almost entirely made of paper. There are no glues, resins or binders made of volcanic fiber.
The number of layers of base paper depends on the thickness of the volcanic fiber that is produced.
Refer to the following diagram as we proceed with the explanation.
Production of volcanic fibres
In the laminator, the layers of paper pass through a zinc chloride bath, which is an acid.
The zinc chloride bath makes the surfaces of the individual fibers, which form the paper, chewy and sticky.
These chewy layers of paper are then pressed together.
The gelatinous fibers create both a stronger bond within each layer of paper and a stronger bond between the layers of paper.
They come together to form volcanic fiber, a chemically pure product with unparalleled physical and electrical properties and a unique bonding force.
Once the layers are joined, the volcanic fiber enters the leciviation tanks. In this process, zinc chloride is gradually released from fiber in a series of water baths.
These water baths have gradually decreasing concentrations of zinc chloride in them.
After the fiber has finished its path through the linciviate tanks, it has only one trace of zinc chloride (typically less than 0.1).
The fiber then passes through the drying section.
In this process, the fiber passes over a series of large heated rolls that dry the fiber up to its final moisture content.
Next, the fiber is grilled. The calendar is a pair of rollers that significantly compress the fiber, making it smoother and denser.
After the calendar, the fiber is wrapped in master rolls or cut into flat sheets.
The fiber that is transformed into master rolls can also be cut into narrow tolerance coils, virtually to any width, but that process is performed after the fact, not as part of the overall production process.
The volcanic fiber, produced by this process, is almost completely pure cellulose, devoid of glues, resins or artificial binders.
In addition to trace elements, it contains completely natural components.
Volcanic fiber spacers are items that cost relatively little, about three euros per sheet in different colors.
Ps. Resin is not cheap so sometimes it is better to take them already made.
I say this because being the spacers in volcanic fiber is more for personal satisfaction than a necessity.
Consider that then the original production of volcanic fiber is an industrial process, your artisanal product is not the same thing.
My advice is not to waste too much time making the materials if the time you have available for this passion is not much.
These are choices but they must be evaluated.
