Helm size formula

If a head was round , the circumference C would equal 2*pi*r.  So the radius of the head would equal C/(2*pi). 

The circumference of a padded helm with .75" of padding CH should equal 2*pi* (r+.75).  Replacing the r with the formula above gives CH=2*pi* (C/(2*pi)+.75).   Simplify to CH=C+(2*pi*.75) Again for our 23" head this gives a helm circumference of 27.71" or an additional 4.71 inches of circumference to allow for padding.  Round it up to 5.

To put it another way, multiply the amount of padding to be added by 2pi or 6.28 to get the amount to add to the helm circumference.

8/9/12 - Irish night at the Open Shop

We started out with barley porridge, asparagus in rice brought by Deirdre and spicy pears in wine sauce made by Gunna and Evie.  (Pears in spicy wine sauce?)  Yummy food!  Jacki and Maelgwyn spent some time geeking out over Y Gododdin and parchment and letters from St. Patrick and other cool discussion topics, but then we all got to work.

First-time visitor Seanan (Shaw-non?) already has his armour together, so he helped out with war shield painting and joined in on the pell-work session later in the evening.

Grain'e made custom patterns for her vambraces and I cut them out for her out of roughly 6 oz. oil tanned leather.  (Note:  Grain'e made a donation to the shop fund for the leather and aluminum.  Yeah!)  These would be way too light if we weren't adding some serious aluminum splints to them.  We patterned and cut out some .125" thick 6061 T6 aluminum splints which will make these plenty rigid enough for spearwork.  Speaking of spearwork, Grain'e came out and worked with the spear while the rest of us were beating on the pell.  Seanan, Grain'e, St. Patrick ...was it Irish night and somebody forgot to tell me?

Dierdre (She's Norse-Irish, so that's...not really different at all)  had recently made some great Mongol-style fighting pants for Wolf and also a nice white under-tunic.  She helped a lot with the shield painting, trained at the pell, and then did some more shield painting.

 

But Wolf is a Mongol who would never ever have even visited Ireland!  He worked on stuffing the channels in his helm liner, did some pell work, and may have even snuck in some shield painting when I wasn't looking.  In the background Ben is working on his own helm liner, which is nearly finished.  Ben also come outside for pell work.

Wyllow mac Muiredaig is a Scot.  A descendant of the Dal Riada.  Who were basically an Irish tribe that settled in Caledonia and forgot to go home.  She worked on weaving hand-spun wool to make a test piece for experimenting with fulling methods/recipes, and helped others with their projects.

Jacki carded wool and spun some yarn while Evie watched and rested up from her cooking efforts.  In the background Belle was on her computer researching 12th century French music for her upcoming presentation at Laurel's Prize Tourney.

Gunna browsed through one of Wyllow's books on Roman cooking.  Will she get hooked and start putting garum in everything?  Only time will tell...

Frosti came out to visit with folks, do a little shield paining, enjoy some good food, and discuss next steps for his armour plan.  And that was enough for one night!

First Thursday in August - Period Cooking Night!

We got off to a great start with a slow-roasted chicken stuffed with venison sausage. As you can see, the photographer did not get there before the ravening horde, I mean, before the first diners started in on the chicken.

For a side dish we had the cabbage that was cooked with the chicken and more sausage, and a Roman sauce with tumeric and laser. On the table we had another Roman sauce with frutum and mustard seed. Both were excellent!

Wyllow managed to get some work done on her gorget earlier in the week:  She dyed all of the roping lines with iron to get a dark brown near-black color.

During Open Shop she added a band of indigo on the outside edges as a test.  If this goes well she will add some red (brasil?) to make it purple and then dye the area inside of the roping the same way.  She plans to use buckthorn on the roping itself to make a golden yellow.  The resulting gorget will have the heraldic colors of Calontir where she first started playing in the SCA and where she learned rapier fighting in the secret rapier underground movement back in the '90s.

Many of Wolf's plans came to fruition this week as he picked up his beautiful "custon Iolo crossbow". For any fans of the Ultima computer games or the Myth Inc. fantasy books, yes, Iolo is real and he really does make crossbows. Verra nice ones! This is his new target bow, but he plans to commission a combat bow as well. 

Notice that Wolf also finished assembling his half-gauntlets.  Here he has borrowed a pair of my deerskin gloves to wear in them.  The supple deerskin is great for swordfighting or shooting or anything else where you want leather protection but you still want to be able to feel what you are doing.

We welcomed first-time visitors Bastian and Tib and Rene'  to Open Shop night.  Tib and Bastian came to work on gorgets while Rene came to provide moral support.  And to read!  As you can tell from the back-drop, this is a good place for reading.  Bastian is making a late-period steel gorget from 18 gauge stainless, while Tib is going for a brigandine-style gorget using pale grey/beige leather and hidden aluminum plates.

Cameron managed to dodge the camera by hanging out in the garage and working on the aluminum splints for his vambraces.  The new (to me) belt sander provided by Duke Hoegarden made this process much faster!  Cameron also showed us his new recurve bow but nobody took pictures of it!

Evie and Gunna and Artorius hung out in the kitchen and baked cookies.  The 3-layer pin~ata cookies with frosting and M&Ms in the middle were awesome.

Ben sewed up all the channels in his new helm liner and began stuffing them with cotton balls.

Dierdre took the night off from peening rivets in her helm to work on a weaving project indoors in the air-conditioning.

Wyllow also did some weaving, finishing up a sampler of several shades of red from her recent dying project.

Tristan and his dad managed to avoid the camera by working in the garage on modifying hid gorget, but we caught his mon doing some hand-sewing on one of Tristan's shirts.  I know I heard their names again last night but I'm afraid I didn't do anything sensible with them like write them down.  Tristan has turned 16 now and is ready to get authorized on the adult field for armoured combat.  I'm looking forward to having him in the War Company with us this fall!

3 Weeks of Open Shop catch-up, 7-5 through 7-19

 For Crown Tourney they specified a particular size and shape of honor shield, which gave me a good excuse to make a new one.  I started with a 1/4" birch plywood blank cut to the specified size and sanded, then painted it with gesso to get a smooth white surface.  I took some original line art that Nora drew for me and reduced it to 45% of the original size before cutting it out.  Then as I traced it onto the gessoed surface I reduced the amount of fur detail by about 50% as well.  I made up one good "ray" template and traced it repeatedly around the shield.  Then I painted the shield from the middle out so that I wouldn't accidentally get my hand into the wet paint.  The only place the gesso still shows is in the hound's teeth.  With the red eye and tongue this looks like a very fierce war-hound indeed.  Note: the "gwyn" in Maelgwyn clearly derives from cun which means hound.  The "mael" is less clear but may be from the same indo-european root as maelstrom, malevolent or possibly mallet.

 

Here are a series of progress pictures for the 16th century gorget for rapier fencing that I've been making for Wyllow.  First I made an s-shaped stamping tool in order to achieve the roping effect.  I cut and shaped a piece of 18 gauge mild steel and then cut a notch in the end of a short length of 1/4" rod stock to receive it.   Note that it is held together by pressure...no welding or even soldering was done to make this tool.  In the picture below you can see the sharp flare at the bottom of the neck piece which allows it to nest with the outer collarbone-covering piece and prevent gapping once the pieces are strapped together, while still permitting considerable freedom of movement.

 Here we have Colin's new gorget, with an extra flare at the bottom of the front piece to make him comfortable and a stainless steel plate over the front of the throat to make me comfortable.  My theory is that the front of a gorget should hold it's shape under impact in order to transfer the force to the muscles on the side of the throat rather than crushing the trachea.  Others are welcome to have their own theories...I like mine and I'm sticking with it.

 

We did an initial dying pass with iron disolved in vinegar to get this shade of black, but Colin decided he wanted it darker and re-dyed with a modern dye  before final assembly.

 In these last three pictures you see the final product in its native habitat, keeping Colin safe while he shoots anyone who would oppose us.  (Hi Gaston!)

With a gorget it is often wise to try the design out with the specific helm that will be worn with it, because an otherwise successful design just might not work with any given helm.

 Here Gunna enjoys the peace and contentment that comes from eating beef-and-barley porridge.

 Wyllow helps Frosti plan out his new tunic.

Kambreda (the artist formerly known as Nora) scares Gunna away from her unfinished porridge by grinding carbonized chicken bones into a fine powder for use in paints and other pigments.  The bones were placed in a nearly-sealed metal container and burnt in a fire to reduce them to ash without enough oxygen to actually burn.

Soon Gunna's porridge will be too cold and she will not want to eat it all up.   :)

 Meanwhile, Wyllow and I asked Kambreda to draw up a pretty capital U for our letter of intent to enter Crown Tournament. Her art and creativity far exceeded our expectations.  Kambreda didn't even know that the unicorn was part of our current Queen's heraldry.  The Queen was delighted when she saw this and exclaimed that she was Kambreda's newest fan.

 Gunna has decided that this sofa is just right for braiding and arranging Belle's hair.  She is sharing techniques she learned in a recent Kings College class taught by Jean Marie (who doesn't love us anymore, 'cause she never comes to Open Shop like she used to.)  Wyllow and Belle took notes and used the methods Gunna had demonstrated when they prepared their hair for the opening procession of Crown Tourney.

Wolf bevels and burnishes the edges of his half-gauntlets to get them ready to soak in glue and bake.

Josh is soaking his half-gauntlets in the glue bucket here.  Once bubbles stop coming out of the leather it is time for baking.  The second gauntlet got a lump of undissolved glue on it, requiring more rinsing in the glue solution to prevent an unsightly mess.

Here Wolf is placing his half-gauntlets back in the oven for another 15 minutes of baking before we adjust the shape again.  Soon they will stiffen up enough to hold their shape and we can let them bake without further adjustment until they are mostly dry.  Next week he will need to sew on a palm strap and sew together the cuff to complete these gauntlets.

Artorius and Jenna play chess while Gunna helps Belle design an underdress (13th century Norman) and Cameron ponders the wisdom of a 6th century BC Greek set of armour.

Maria cuts out part of her new dress with advice from Wyllow.

Linden is all set up for leather tooling and seeks inspiration from assorted reference books and costuming manuals.

Ben is trying to add enough padding to make his new helm fit his head.

Ben is using blue camp-pad foam as a temporary measure to pad his helm until we can make up his linen helm liner.  He purchased this used helm on the Internet and didn't realize quite how large it would be.  It will get him on the field in his own gear for now and perhaps later he can buy or make a more fitted helm.  Below you can see Ben and I starting to lay out his linen helm liner.  Pay no attention to the bald spot on the top of my head.  It is clearly an optical illusion or a trick of the light, and in no way indicates that anyone in this picture is getting old.

Deidre has made significant progress on assembling her Vendel-era Valsgarde 6 helm (7th century Sweden).  Soon she can add the nasal, cheek plates and face guards.  Then she can begin pillaging helpless villages throughout Europe, North Africa and the Middle East.

To quote the noted scholar Robert E. Howard:

"Serpent prow on the Afric coast,
Doom on the Moorish town;
And this is the song the steersman sang
As the dragonship swept down"

See http://www.calonsong.org/CalontirSongs/thorsson.htm

Daniel has taken his turn out in the heat and managed to hammer out some elbow cops that are nearly ready to strap.  Clearly the heat was too much for his shirt and it has caught fire.

And if we give her a few moments away from helping everyone else, Wyllow is sure to be caught red-handed once again as she works to interpret and implement a complex recipe from the Plictho.  I think this one includes madder, brasil, cochineal, calcium carbonate, oxalic acid, and pretty much every trick in the book except eye of newt.
