lino harness

Double- walled harness made of layers of glued cloth, Epic Empires, August 2014

This page is part of the documentation of my armour; the beginning would be here: linothorax armour

This armour basically consists of layers of cotton linen and undiluted, waterproof, transparent-drying D3 wood glue. It withstands real blades and arrows, thus offering genuine protection.
Paddings are made from cheap camping sleeping mats, lacings are polyester- cord, glue is Pattex classic, side closings are self- adjusting velcro.


Symbols and runes are made with window- color- contour and the surface was then sealed with a mixture of 4 parts transparent H3- glue and one part acrylic paint. All colours: acrylics.

The only metal components that were used are hollow rivets that fix the lower visor to the helmet and function as initial linking of the two walls of the harness.

Elsewhere Iīve already compared the substance with modern armoured vests because it functions more like todayīs ballistic protection than medieval plate armour:
The glue turns the layers of cloth into an inseparable composite material whose surface from a certain thickness on will become invulnerable to blades. The point of an arrow can neither displace nor cut the material and thus is stopped.

Lemme mention here again that this kind of composite wonīt protect you against modern firearms. Just donīt get hit, hear me?

Layers of glued cloth are extremely tough but always stay flexible. This is a positive attribute insofar as a considerate amount of impact energy will be absorbed that way but is a disadvantage as the material will dent much easier than a metal plate. In early warfare the battlefields were just crawling with blunt high- energy- impact- weapons like clubs, heavy but not very sharp swords or maces of all kinds (not to mention armour- piercing pick- like devices against which the only defence is not to get hit at all). So with lino (even more than with metal armour) the idea is not only to stop a weapon from biting pieces out of you but also to avoid “compression traumata” which occur when the armour after a blunt impact makes unhindered physical contact with the wearer and transfers energy (like a hit on chainmail worn without sufficient padding). The consequences of such a concussion would be bruises, lacerations or even bone fractures.

And hereīs the receipt I came up with: arched components and two- walled crumple zones.

Because I deliberately forego the use of strengthening the material with metal plates which would efficiently restrict unwanted flexibility (they could be riveted on or glued in) the harness has dentable areas which absorb enough energy to prevent such injuries and help to impede penetration.

Breast and back are double- walled with about 3 cm airspace in between. Each tier in itself is impenetrable but flexible, thus eating up lots of impact energy but nevertheless forbidding penetration or cutting. A compression is possible but difficult because all plates are arched for more stability and better energy dissipation. Also at certain places there are “ridges” that further strenghten the arched parts, allowing bending only in preplanned directions. Nevertheless the armour will “work” with approprate strain but afterwards just bulges out again.
The contact surfaces to the wearerīs body are minimized by the under layer consisting of many strongly arched separate areas; only the recesses rest flat. Padding here is not necessary:  should enough energy manage to get through, these areas will “work” too, coming up and dissipate whatever force would hurt me otherwise.


Each wall consists of at least 12 layers of cloth (cotton linen), overlappings adding layers in preplanned areas, making the armour substantially stronger there.  It is not necessary to vary the alignment of the clothīs warp during manufacture of the layers, you only do that with armour made of quilted fabric. I used black cloth; this is least noticeable in case of colour abrasion.

The minimized contact surface together with the arched areas of the armourīs under layer permits  to largely dispense with isolating padding, thus allowing air circulation under the armour. Whoever enjoyed this luxury on a hot battlefield never again wants to go without it! This and the armourīs weight of under 7 kg make it very well suited for use in hot climate.

The side plates covering the upper arms are non- removable and arched like the other components. To save weight and volume they look like a silhouette of Africa instead of being rectangular or crest- shaped. In their main- impact- area a second arched plate rests on a layer of padding; that way implementing the two- tier- principle. The undergarment again is padded on the upper armīs outer sides.

Of course this construction is way more complicated than a classical greek/ roman linothorax. The reasons for taking the long route were:
- my desire for minimized contact surface (meaning air circulation and cooling) together with more body coverage than the originals
- the materialīs processing options: plate shears can cut only up to about 10+ layers but I wanted more than twice as much
- the armourīs design to better be able to resist heavy blunt impacts than the originals
and eventually the wish to find a shape for the armour that as much as possible differs from euro- antique examples: this is a chaos warriorīs armour and thus authorized to “look different”.

Iīm talking so much about the function of the armourīs individual components because otherwise one would reasonably have to ask why I didnīt just copy an approved and reliable construction  like a “Lorica Segmentata” (the roman legionaireīs metal- armour) or build a “tube- and- yoke- armour” like a greek Linothorax; both would have been way less time- consuming and complex.
Well, in fact the project got a little out of hand with me coming up with more and more possibilities for using this amazing material. Its unique way of manufacture grants much more freedom than metal or leather, all the while needing almost no tools, know- how or soundproof workshops. You can in fact work in your living- room.
Which I did over a period of almost three months...

Whatever. Back to topic. The helmet was ready which is necessary for trying it on together with the harness over and over again to make sure the equipment doesnīt lock or becomes entagled.

Step one 1: Mould making; encore une fois...

Below: the harnessī bottom wall made of cardboard and tape.


Functional spec says: minimized contact surface - already repeatedly mentioned- that will facilitate air to get under the armour for cooling (this is a main feature) and predefined areas of movement where the harness will distort when creased forcibly, thus coping with the materialīs flexibility.

Thatīs why the form consists of single arched elements. Contact faces with the body will only be the shoulder straps and the recesses between the bulges.

On first glance the harness looks like a “musculata” armour. However, it is not anatomically “musulated” but the recesses are arranged rhombic from plexus down. The harness only reaches below my ribs; the abdomen will be protected by an extra- wide armoured “belt”. On the picture at the very top the gap seems wide but when bending forward even slightly (like when fighting) the belt slides over the harnessī lower edge and closes the armour.

P_LinothoraxHar(3) P_LinothoraxHar(4) P_LinothoraxHar(5)

Above: arching cardboard plates, from left to right:
Creasing the plate “like it or not”, thus forming a bulge, then cut out overlapping area, then stick together the edges of the cut- out area. When all is ok, unstick plate once more and make a mirror- inverted second one. The single components are then assembled using more tape.


Left: Enhancing the bulges with foam- plates
As it became apparent the bulges generated by folded cardboard were insufficient to make the armour keep adequate distance from the body (although they are indispensable to create good fit). So they were enhanced with foam- plates cut out of a cheap camping- mat.

The bulges are rather exaggerated to be on the safe side because only the finished work- piece will show if the arching of the individual areas is good.

Right: construction of the collar over an auxiliary structure made of foam that will be removed again when the collar becomes stable.


Left: My first try to build “floating” armour plates

The idea was to glue single plates onto smaller foam underparts that are invisible from above, thus making them “hover” over the armourīs under layer, that way achieving the 2- tier- principle of a “crumple zone”.

But unfortunately first of all this looks like an autobot transforming into soap bubbles and second:
How can one decently brag about “functional armour” when it has gaps all over that instead of stopping incoming stabs and projectiles will sort of automatically lead  them into the upper bodyīs most vulnerable areas?

Catastrophe! A monumental, enormous, immense failure that almost lead to the project ending in the garbage bin instead on the battlefield and resulted in an almost two- week- long pause for reflection that busted the last remnants of my time schedule.

Deadlines donīt wait. They never do. I hate that.
So this is what got built in the end:

P_LinothoraxHar(10) P_LinothoraxHar(11)

Above: The harness consists of only two components: the bottom layer with the arches and the top layer consisting of breast, collar and back. Built- in paddings arenīt necessary; the stacks of green foam under the collar on the left picture are only sustainers that were omitted in the finished workpiece.
The shoulder plates will later rest on the outer sides of the collar but be fastened to the shoulder straps.
The “shoulder straps” of the inner layer are an integrated part of the armour. Hinges are not necessary- the material is flexible enough for just being bend apart when dressing the harness.

Step 2: Cloth and glue. At least 12 layers per tier but not many more...
Then both components are disassembled again, placed onto two separate dummies (stuffed plastic garbage bags) and “linofized”. Here Iīm only showing the building of the more complicated bottom tier.


Above left: The form has been completely taped to protect the cardboard and facilitate easy detaching of the workpiece once it has dried.

Above right: And after weeklong preparations for building the helmet and the form finally the building starts, first in the recesses: glue // cloth // glue, patch by patch.
The first layer wonīt stick well because the patches tend to slip on the glued form. Itīll get easier with the second layer.

Spirit of optimism! And better not think about the deadline:the convention is in 4 weeks and I donīt have something to dress! The pictures were taken july 1st, and the convention is at the beginning of august...

P_LinothoraxHar(20) P_LinothoraxHar(21)

Above left: The first layer; on the left the front side, on the right the back. For the first coating  I donīt spare glue because the idea is to soak the cloth as much as possible. For the upper painting I use as little glue as possible to minimize the development of “tears”.

I use undiluted glue (D3 wood glue, waterproof, transparently drying) and black cotton linen.
The uneven surface with all the recesses cannot be covered with single pieces of cloth because that would wrinkle, but the straps shown (about 20 cm long and 3-4 fingers broad) will do the job. They are glued on overlapping and when set form a single coherent work piece.

The problem with overlappings is: each one is a layer more. Put many of them one onto another and you get bulges. We donīt need that. So it makes sense to put the next layerīs overlappings somewhere else. They alternately can be deliberately concentrated in areas you want to strenghten especially.


Above left: The transparent drying glue produces a black work piece. That way paint abrasions will only show black, which I consider least annoying.
Not one patch fits exactly; all are fit only approximately.

Above right: Therefore every 2 or 3 layers I trim the edges with shears, later plate shears. The final trim is only done when all layers are applied. I build only as thick as plate shears will barely bite.

After 4 layers I detache the harness from the form for the first time so it can dry from the underside too. Nevertheless itīs put back on andīll stay on the form until completey finished.
4 layers of lino are flexible. Way too. Frustradedly one asks oneself how something like this will ever be able to turn back swords and casts nervous glances onto the timetable.

So: more layers. The answers to most linothorax- questions are: “build more layers”.


Left: an accident

Air pockets. On the picture theyīve already been cut open. They occured when the cloth didnīt bond completely with the surface, tautened over the recesses and dried that way.
Air pockets cannot be ignored because theyīll destroy the character of the composite material.

To get rid of them cut away all loose material, smooth the crater with sanding paper and glue more layers on.

2 layers per day are possible: one in the morning before going to work and one in the evening when off- duty. Best have only so many components ready as can be processed in about one hour.

Hands cleaning: just wash with water. Not a patch on Pattex- clogged fingers (for that I use nail varnish remover- my own cheap one, not my girl- friendīs of course).


Step 3: Assembly of the harness
Above left: the under layer, Middle: the upper one. It will at first be attached to its counterpart with hollow rivets, but stability will come from glueing on more layers of cloth.
The rivet points lie at the endings of the ramifications. The next layers of cloth will cover the upper and under tier of the armour as well, thus turning the riveted areas into one single component.

Above right: Both layers are riveted together. The upper tier is slightly under tension which itīll never loose, thus lifting off a few fingers breadth from the lower tier.
Doesnīt look cool or even fubctional yet, though...

The irregular-cut outer collar on the right picture is a bright idea to cope with a symmetry problem that began to arise quite early with the building of the armourīs bottom layer. So I came up with the plan not to give the armour any straight edges but cut all rims asymmetrically. This even contributes to its exotic character: not bad, considering that the warriorīs deity is the “changer of the ways”- and en passant slight symmetry erros are concealed.


Above left: The hollow rivets on the ramifications of the upper tier.

Above right: Covering of the gaps with cloth/ glue, thus producing an coherent surface. “Smooth” it didnīt get, though...

The asymmetrical point downward is not glued onto the bottom layer. It belongs to the “crumple zone” and gives in with an impact. The openings left and right from it also serve as water outlets in case it rains into the armour over a longer time period.


Above: the two- layer- concepts of crumple zones
Left: side view; front plate faces to the left.
Middle: view from above onto front plate and outer collar
Right: from above onto the outer collarīs back side
The provisional thread is for stabilisition. The upper layer of the harness is attached under slight tension in order to stand clear of the lower layer. It wants to move in the dirction of the backside and make contact at the front. Cords like the one in the picture prevent that.

An impact-event therefore will not flatten the upper plate against the lower one at once but ellipitcally deform the outer collar first. Later the side shields will make that even harder.
In the final assembly the cords have changed their position: the better place is on the back plateīs middle region left and right.

The back crumple zones works slightly different: the outer plate will relatively easy establish contact to the inner one but the strong arching of both plates offers no possibillity for conducting energy onto the body and thus they withstand the impact..


Above: The harnessīside- closings with self- adjusting velcro

After both layers of the harness are assembled it is cut under the armholes.
Only now I can try it on for the first time. It fits very well. Awww-right...

It will be closed with broad straps of velcro. Both sides can be opened but in practice I open only one.

Velcro is sewed on sufficiently big pieces of cloth and securely glued on. The hook side on the harnessī front plate points outside (so as not to bite the undergarment) and is attached flexibly beside the armourīs edge. The velcroīs fluff side points inward and is glued directly onto the armourīs back plateīs inside (see picture above right).


Above: on the left the front part of the harness with protruding flexible velcro (hook side outward) on the right the harnessī back with the velcroīs fluff side clued onto the armourīs inside.
Thus the fastening (which is much too modern for fantasy) completely vanishes out of sight with the armour closing seamlessly.

The harness can be dressed without help and the flexible- mounted velcro strap automatically positions itself in the optimal angle for max efficiency.


Above: a last layer of glue for the inside. Notice how far the two- walled harness with outer collar can be bend apart. The glue will dry transparent, rendering the inside black again.

After wearing it for a few days in wet weather the insideīs colour turned whitish. The effect was revised when all was dry again. The armourīs consistency didnīt change, though.
If I had painted the inside with a mixture of 3-4 parts glue and one part acrylics then nothing would have happened. I donīt count it as a problem though because nothing of this is visible from the outside.

The harnessīvelcro fastenings are already attached.


Step 4: shoulder shields and final assembly
In the areas where the side- shields rub on the outer collar undue wear and paint- ruboff will occur if nothing holds them off. Therefore small pieces of wood are glued to the outer collar to serve as separators. They are fixated with a glued- on piece of cloth each. On this the side- shields are build and fitted.

The velcro tape on the shoulders of the inner layer will be used to establish the correct position of the side shields. When attachment points and required length of the shield straps are determined, everything will be glued together and covered with a few layers of composite..


Above left: The shieldīs forms are made of arched cardboard, tape and clingfilm (Iīd use only tape meanwhile). Each shield has its own form; thus they can be manufactured simultaneously.
The smaller upper plate is to be glued to the lower one separated by a layer of padding made of foam. The padding is smaller than the actual upper plate and will vanish in a shadow gap.

Above right: 12 layers of cloth later: the lower plate hasnīt been glued in the contact zone of the foam because Iīll use Pattex for it which wonīt bond with glued surfaces. The lower side of the upper plate also isnīt glued but left “textile”. When the shields are assembled Iīll glue any leftover areas.

P_LinothoraxHar(43) P_LinothoraxHar(44)

Above left: runes und symbols made with with black window- color- contour. The ornaments were then fixated with a mixture of 3-4  parts glue and one part acrylic paint.

Above right: for the sake of completeness the painted shield- but thatīll come later...


Above: a side-shieldīs attachment from below. From the middle of the shield instead of long straps a single flexible piece of composite only 3 layers strong branches below sholder-height into two tearproof straps (cloth-glued webbing). These belts connect in front of and behind the shoulders to the inner layer of the harness.
Their correct position and length was determined with an extemporary velcro- tape- fastening that later was glued together and covered with a few layers of composite.

Thus the side shields can not only hinge up like a classic knightīs shoulder (pauldron) but can smoothly be pushed up, thus following the armīs movements much better.

A cord under the upper arm prevents the shield to move more than necessary.

The use of glued webbing straps and flexible lino- parts made of only 3 layers of cloth instead of leather straps means that all attachments only move when theyīre required to rather than “dancing” with every step. Thus the big side shields are well under control.


Above left: view from below into the harnessī inside

Above right: from above. Each shoulder plate is stabilized at the top front and back with loose cords that restrict the plateīs movement range. From the outside the cordīs knots are visible.

P_LinothoraxHar(45) P_LinothoraxHar(46)

Above: One of  6 chinese oder “Josephine”- knots. Actually a large-scale decorative knot it wasnīt meant to really hold anything- but I glued it on and now it does.


Above: pictures from the test phase. The armour is fully assembled but yet neither embellished nor painted. The tests serve to determine the correct places for the different attachments, the suitable length of the cords that limit the shoulder plateīs movements (here green and makeshift) and establishing the definite shape of the plates.
The corrctive actions can be outlined with: Cut off edges until you can move well. Only when everything operates satisfactorily the armour is decorated and painted.

Above right: View into the decollete. The undergarment with padded collar is still missing, so one can perceive how little the armourīs bottom layer touches the body and how much the upper tier stands off.


Above: the range of movement of the shoulder plates from the rear to the front. One of the insights gained with these experiments was: the upper breast plate in front of the right arm protrudes too far into the armīs movement zone and had to be cut back.

step 5: painting and decoration

Below left: ornaments and runes are done with window- color-contour. The substance is flexible (after all it was made for glas designs) but doesnīt bond reliably with the glued surface (again thatīs what it was build for: to be able to be lifted off glass plates if needed).

Below right: Thatīs why the surface is now sealed with a mixture of 4 parts glue and one part acrylic. The paint changes the consistency of the glue to “even more viscous” and almost merges the ornaments with the ground. A suitable hard impact can of course still damage the adornments, but hits with foam weapons donīt fall into that category.


Above: The actual painting of the surface is done with undiluted acrylics.
Originally I wanted to take over the “bleeding” blue colour- scheme of the helmet, but how to transfer that to such a big area: bottom gold, top blue with single bleeding traces running downward? Also that way the symbols and runes would be “camouflaged” resulting in them not being clearly vivible. Bad idea. So blue with golden runes it is.

Above left: drybrush gold. Thus all runes and lines are accentuated.

Above right: and then blue is painted around the ornaments. A very dubious pleasure, but this procedure gives a better result than painting it all blue and then repaint the ornaments with gold. On top comes a wash off black (thinned paint that settles in all recesses) and “dirt”.

There is no varnish so that colour abrasions -should they happen- can be restored even on-site in the next game-pause with quick- drying acrylics. But that wasnīt even necessary.

So much for the harness. And because helmet and harness alone donīt make a suit of armour thereīs a fourth page in this documentation for the add- ons. If you want to read straight on, just follow the link below.
