Gambesons and arming doublets   1 comment

I have had a few questions about making gamesons etc.

I am just posting these info sheets up here for now. These were done many years ago and my undersanding on making funtional foiundation garments has developed over the years, but these are a good place to start.

A New Helm – Part 3, Finishing Up   3 comments

After all the hammer work is done it comes time to start sanding. I start by using a 80 grit belt for the initial cut back. This is a bit aggressive but as I am working in reasonably thick metal I can afford to do this.

I then go over it with a 120 grit belt looking to remove the previous sanding marks. After this I use greaseless compound. This is a paste that goes onto a buffing wheel and acts like a soft sanding belt. Again I work over the entire helm looking to get an even finish. I am not trying to get a perfect finish. Some sanding marks are OK.

Before starting the polishing I put in the roll on the bottom edge and set the holes for the liner and chin grill.

Polishing is done first with maxicut on a sisal wheel. Then multishine on a stitch wheel.

The final polish is done with green chrome to bring out a deep finish.

The final bits are putting in the liner rivets. These were cast findings I have had for a while. Cast by Sir Felix from a master made by Sir Leofric. Added also was the chin grill. These grills are a SCA sport fix. They work well and give you excellent breathing, but are a modern tweak.

So there is the new helm. I am not totally happy with this project. I am planning on doing it again later in the year using spring steel. But until then it will do nicely.

A New Helm – Part 2, Shaping   Leave a comment

The helm blank is now together and it is time to light up a hot torch and start hammering.

I am using a LPG/oxygen mix to get the material hot and just hammering it down onto a ball stake.

This technique is very fast once you get it going, as in “holy crap that was fast”. I managed two complete heating passes on the helm in the first session. The basic shape is already there. I should have been able to do a clean up pass under heat to have the main shaping done at this point…

ImageImage

 

A few issues emerged. I pulled up the keel as the first thing. This was a mistake and I should have waited until I had the basic shaping passes done. Pulling up the keel will ‘lock’ the from to a significant degree and make it very difficult to majorly change the shape after you have put it in. It also resulted in a major stuff up.

The other big issue I had was the helm was way too big. I am used to being able to size down a helm as I go. This is not that easy with this technique. I was going to spend a lot of time and effort working the helm down. As it was at this point, it was about one inch too big in the side and about two inches too much front to back.

Fortunately it is just a matter of working the form down to reduce the size.

I was also going through O2 at a furious rate, this is partly using too much heat in places and having to do extra passes.

Working it down on the big T-stake. Unfortunately I lost some of the nice shape in the skull.

Working it in. You can see where the keel is not coming down with the rest of the skull.

The black lines are me working out where the occularia will end up.

 

Image

 

At this point it was time to work down the front and start pulling up the chin section. I have done this in some ways with the full visors on previous projects. As your work the visor (or front part in this case) down you end up pushing up a ‘wave’ of material as you go. So you just work it down to where you will have the occulaia and you have the basic form.

Image

 

I then use a fluting stake to define the shelf.

Image

Image

 

 

 

 

Once I had the face looking OK I did an initial planishing run. The grid is so I can keep track of where I am up to.

Image

 

 

I was having issues with the keel. As I mentioned, I brought this up too early and it hampered me in the sizing. In an effort to get it looking right (you can see in the photos it is way too tall) I managed to fold it over at the front. 

Image

Image

To fix this I decided to cut out the metal where I had folded it under, hammer in the remaining keel bits and weld it all back up. I was a bit disappointed that I needed to do this, but as the entire helm was welded anyway I should not be that bothered by this. I did not take a photo of the fix up. I also tidied up the keel over a fluting stake and a bit of heat.

So here is the helm in the process of being cleaned up/planished. (Before anyone asks, the red on the table is me making up some red leather belts, not a sacrifice to the armour gods.)

Image

Planishing is one of the more tedious processes. It just takes time. You also need to be aware of getting to a point of diminishing returns. Yes you can hammer the piece to being very smooth, but you can also just cut things back with a sanding belt. 

That now is the primary work completed. I had to adjust and then square off the bottom edge. Cutting out the occularia was done with a angle grinder and jigsaw and then files to clean it up.

Now onto finishing!

A New Helm – Part 1, putting it together.   Leave a comment

This post is all about making armour…

As many of you may know, I love sallets. I love the lines and shape of them and have in time modelled my kit and impression around the need to wear them. Anyway, my current sallet has been in service for about 15 or 17 years. I love that helm but it was getting time to replace it, as all things will wear out eventually.

I intended to replace it with basically the same thing. There would be a few small changes to things I got wrong all those years ago. I have been intending to get started on this for a long time, but always had other projects on the go. I have also been looking at some of the posts on Armour Archive about a raising technique that makes things very fast and I wanted to try this new method out.

Basically you make up the helm in flat sheet with only two dimensional bends. You weld it all up and then sand back the welds flush. Then, under heat, you work the form down to the desired shape. The technique was developed by Robert Macpherson, whose work is fantastic and I wish I had 1/10 of his eye and talent. The raising  involves compressing the metal and hammering the form from the outside rather than working the form from the inside as is common with a lot of modern armouring. I did a test run on a shield boss and it worked a treat. So I drafted up a pattern based on the old helm and off to the workshop!

Here is the pattern mock up next to the old helm.

I drafted the pattern over the old helm. This ended up being a big mistake. This technique requires you get the pattern spot on, as I will explain soon…

Cutting out the plates.

Image

 

From here it is a straight forward job of bending the plates and welding it all together. The top portion of the helm is in 2.5mm mild and the bottom plates are 2mm.

Top of the helm welded up.

The front of the helm. Top welds have been sanded back.

Image

Helm all welded up. I should have done the bottom plate in one piece. The weld there would cause problems latter on…

Image

After this I sanded back the welds on the outside. I am supposed to do the same for the inside welds but these were relatively flush anyway (the bonus of doing with gas welding) so I did not spend too much time doing this.

The next step is to light up the torch and start hammering.

Conditioning for Beginners   3 comments

 A while back someone asked me what a good set of exercises would be for someone starting out in armoured combat. I am a bit late in responding to this request as the person was looking to get into some shape for Easter (and this is next week). Anyway if anyone is interested you can always come and find me at an event.

So beginning conditioning.

Most SCA combatants do not come from a sporting background. I was defiantly typical in this regard. Role playing games and painting miniatures do not prepare you for the physicality of armoured combat.

One of the most important aspects of fitness you can work on is your short to medium term endurance and recovery. I wrote post about this here. While I think high intensity intervals are awesome for armoured combat you do need to have a minimum level of fitness to not totally kill yourself doing these. Remember this is supposed to be enjoyable…ok…mostly.

So look to building up a base level of aerobic capacity first. Rowing machines, bikes, elliptical machines and treadmills are all good. If you are capable of running then this too is good and the “couch to 5km” program is an excellent place to start. Be able to sustain 20-30 min of constant effort. Your breathing should be such that you can talk but not sing. This is a heart rate of about 50-70% of your maximum heart rate.

From here you can start doing some HIIT or sprint training. Or a very effective way of building your fitness is to stay in armour as long as possible. Go to the stage you would normally stop. Have a short break and then fight 3-5 more bouts. Just make sure you are able to maintain form and not cause injury.

I would also suggest doing some resistance work. This is more about building up flexibility and your joints to protect them from injury. Body weight exercises here are fine. Squats are king for fighting. So make sure you warm up, just get your heart rate up and your body warm. Now do one complete round of the following. If you can have a break and do another round. Aim to be able to do three rounds.

  • 20 Squats – make sure you are not leaning forward and the weight is on your heels.
  • 10 push ups
  • 20 walking lunges (that is 10 leach leg)
  • 10 dumbell rows (use a big milk container as a weight) or 10 incline pull ups
  • 20 second plank
  • 30 star jumps

Do this two or three times a week but not on consecutive days. Once you can get through this three times then you should be moving onto other routines.

So this is probably a good plan for those wanting to work on their fitness for fighting.

What I do however need to mention is that any conditioning work MUST be backed up by a good diet. Quit smoking. Do this now. Stop drinking all that coke. Eat a lot more vegetables. Avoid processed food. What you eat and drink is the main contributor o your long term health.

B and C duel

 

I would like to present some notes on power generation. In Oplomachia we refer to Frame Weight Transfer, or just moving the body into the cut or thrust in order to provide the power required to hit hard with a weapon. This is a subject for another post.

What I want to address here is the idea of power without effort.

Throwing a good cut is much like firing a gun. Once the initial explosion has taken place in the barrel the bullet flies of it own accord. It accelerates naturally and does not need to be push along. While this is technically not quite correct I would like you to keep this analogy in mind.

What is important to realise is that you will never be at your best when trying your hardest. That is you will be able to move and cut more efficiently if you are going at less than 100%. Almost universally, experienced combatants hit their hardest a around 80% and almost as hard at 50% of their effort.

Think to your own experiences. Have you ever delivered a cut with natural movement thinking it was way too light, only to have your opponent stagger and say that you do not have to hit them that hard? This is now the realm of good technique.

Try this experiment at you next training. Have someone hold out a shield for you to hit. Now hit it as hard as you can several times. Have your partner note the power of each strike. Relax. Take some deep breaths and shake out the arms. Now throe the same cut but at 80% of your effort, stay relaxed yet focus on delivering a smooth cut. How hard was it?

Now experiment with a dozen or more strikes going up and down randomly: 50%, 80%, 30%, 90%, 70%, 50%…Loosen up between strikes. Again ask the person holding the shield how hard the cut were. You may be surprised.

You may need to experiment with dialling the ‘volume knob’ in on the desired settings to find your personal optimal setting.

Another aspect of cutting with power is to applying force to the weapon as smoothly and efficiently as possible. Think again the bullet analogy. We must move the body forward to apply forward motion to the weapon and these needs to be a focused movement. If you are tight or stiff it will be hard to accomplish this smoothly. If someone is trying to go at ‘100%’ they are often too tight.

Imagine a video of your swing that is broken down into ten frames. For how many frames are you applying frame weight transfer? At what point do you squeeze the hand to make a solid cut? A new swordsman engages their muscles too long and then too soon in the movement. They are self-conscious about the attack. They are trying to remember technical details. They are using all sorts of energy to move and direct the sword through all ten frames. A more advanced practitioner, in contrast, stays loose and relaxed kicking off the sword in the first few frames and then not tightening until frame seven or eight. At higher levels this last phase may only occur at frame ten.

This efficiency is not soft in anyway. Efficiency does not slow down or weaken the power movements but limits the duration.

Do not confuse speed and power with effort.
