What\'s wrong with my scutum?
#1
I just got back from the wine and grape parade held in St. Catharines, ON. The parade went well, though I have to admit I was pretty exhausted at the end. Besides a rather intrusive cameraman who insisted on poking his huge lens almost into my face, I had some difficulty with my scutum. It seems that I cannot hold it for long without my left hand going numb. I built the handle from 1/8 inch thick wood strips, off-setting the handle by an 1/8 inch from the shield board. Should I have offset the handle more than that? This is a puzzling question after seeing the pictures of the shields found at Dura-Europos which do not seem to have any handle offset at all. On the other hand, could my scutum simply be too heavy? I made it the usual way from two layers of 1/8 inch thick birch plywood. The dimensions are 33 inches wide (with the plywood layed flat) by 42 inches high. The front of my scutum is covered first with a layer of leather over which is applied a layer of linen (this recipe may be wrong, as the Dura-Europos book says to do just the opposite). There is just linen on the back. The boss is made from 14 gauge steel. Would a construction from birch wood strips, as the romans actually did, be lighter? Has anyone actually made a scutum using birch wood strips and what was the weight compared to a conventionally made scutum? Does anyone know of a supplier of suitable birch wood strips? <p></p><i>Edited by: <A HREF=http://p200.ezboard.com/bromanarmytalk.showUserPublicProfile?gid=neuralmancer>Neuralmancer</A> at: 9/26/04 12:32 am<br></i>

Do you wear Segmentata?<br>
<br>
If so this could be the problem. The cut out section of the top girdle plate may not be deep enough or come far enough forward and you may be putting pressure under you armpit, which affects either your circultaion or you nerves (not sure which, but it's damned uncorfortable).<br>
<br>
If this is the problem you'll need to do some surgery to your seg.<br>

Yes, I wear segmentata. I hadn't thought of the impact of my seg on the blood circulation of my left arm. I'll have to investigate this. <p></p><i></i>

As Mummius says, it could be your armor that's causing the problem rather than the shield. If your whole arm seems to be going numb, that's a good indicator. But the problem with the lorica might not be that it's too high, but that it's too wide. If the girdle plates don't fit closely to the sides of your chest at the top, they may be pressing outwards against the inside of your arm. So it might feel perfectly comfortable when you put it on and move around, but standing at rest with the arm pulled down straight subtly presses the arm into the armor. Cutting down the top edge of the upper girdle plate probably won't help, in this case.<br>
<br>
If you're really lucky, simply tying the girdle sections together more tightly will cure the problem. You might even overlap the loops at the back and tie them that way. Or bend the loops a little to move them back from the ends of the metal to gain a little more space. Actually removing all the loops on one or both sides, back and/or front, and remounting them farther back is a bit more drastic, but should help a lot.<br>
<br>
Squashing or re-shaping the girdle section is a another solution, and not difficult. Optimally, the plan or ouline of the girdle section, when viewed from above, matches the horizontal cross-section of your chest, without much space between the two. The problem arises when there is space at the sides. So if you squash and re-bend the girdle sections (on the floor, over the edge of your workbench or a handy log or protected couch arm, etc.) you can eliminate that space. Obviously that means there will probably be more of a gap somewhere else, but if it's at front and back that's a lot less of a problem.<br>
<br>
It sounds like your shield construction is pretty good overall, so I doubt that the weight alone is the problem. The thickness of the leather may be adding unnecessary weight if it's over 2-ounce or so. (And from what I've heard, the Dura Europas scutum did have linen over leather on the front, but that's from Connolly and not the actual site report.) Your handle is actually set much farther back than the originals, since those were actually made as part of the shield board. Instead of a single circular hole, they cut 2 half-circles (or a half-circle and a trapezoid) about an inch apart, and that strip between the holes was the grip. It can be thickened with another strip of wood or metal (the central horizontal back brace) or wrapped with leather, but it isn't set out from the back face of the shield at all.<br>
<br>
The taller Dura Europas scutum was 41" tall, and it's the biggest one that we have evidence for (for the Imperial rectangular shape, that is). The smaller one was only 37" tall, so those figures make good parameters. 42" seems to be very popular, but no idea why! I make most of ours about 38-1/2" tall, which is the height I worked out for getting the most out of a 4'x8' sheet of plywood. I use a width of about 28", for the same reason. So that would trim a little off the weight as opposed to yours.<br>
<br>
You can get split oak strips from basket-making supply companies, but I've never tried making a shield from them. Much depends on the thickness of the wood, the type of wood, and whether the board is thicker at the middle than at the edges (which can be done partly by using the thicker strips in the middle on each layer). On average, I wouldn't guess that the original shield boards were significantly lighter than one made with 2 layers of 1/8" birch plywood.<br>
<br>
Anyway, most of that is moot if it's the armor that's causing the numbness rather than the shield. As a stop-gap measure, you might use your shield's carrying strap (over left shoulder or right) to take some of the weight while doing long marches, to give you a chance to flex and move your arm regularly.<br>
<br>
Good luck, and keep us posted! Vale,<br>

The scutum carrying strap saved the day during the parade. I would never of been able to finish the parade without the strap.<br>
<br>
My left arm seems to be ok. I feel preasure on the back of my left hand, which is reasonable, and then my left hand "goes to sleep". I need to try adjusting the height of gridle plates. I already have the gridle plates as tight about my body as I can get them (I've even rebuilt the left gridle section so that the gridle plates overlap horizontally).<br>
<br>
I would still like to hear from someone who has made a scutum from birch wood strips and compare the weight. <p></p><i></i>

Hi Neuralmancer,<br>
I don't have much experience with segmentata because I am a late Roman, but it sounds to me like Matt is right, could be a circulation problem caused by the armour. Your shield sounds like you have constructed it properly, from the finest materials (at least for us modern reenactors). Birch is an excellent choice for shields, because it is very strong and light. I don't think anything is wrong with your shield. I would try some of Matt's suggestions and see if that remedies the problem. <p>Lucius Aurelius Metellus, miles gregarius, Secunda Brittanica</p><i>Edited by: <A HREF=http://p200.ezboard.com/bromanarmytalk.showUserPublicProfile?gid=luciusaureliusmetellus@romanarmytalk>Lucius Aurelius Metellus</A> <IMG HEIGHT=10 WIDTH=10 SRC="http://img.photobucket.com/albums/v384/Lucius68/Lucius.jpg" BORDER=0> at: 9/26/04 6:43 pm<br></i>

my seg is at fault. I wore borrowed maille for both days and I had no problem with my left hand going numb from holding my scutum. I was even able to bash barbarians with my scutum without much if any discomfort. <p></p><i>Edited by: <A HREF=http://p200.ezboard.com/bromanarmytalk.showUserPublicProfile?gid=neuralmancer>Neuralmancer</A> at: 10/4/04 2:27 pm<br></i>
