    sights on medieval crossbows

    Post by Todd the archer on Sun Mar 14, 2010 5:11 pm

    First topic message reminder :

    Seeing the thread on set triggers got me thinking; what sighting systems were used in medieval times. I know that sighting over the bolt was probally the most common method used, but think I remember seeing sights of some sort on Italian crossbows. I hope some more knowledgeable people could explain the different types used back then, maybe with pictures.

    thanks, Todd

    Hmm, bolt length is something wich can change when using different bolts.
    Its not really medieval but i am considering making a folding rear and fixed front sight. Anyone seen those on medieval bows? Pictures are much apreciated!!!

    Greetings

    Harmuth describes in "Die Armbrust" different types of sights.
    The ones seen in the italian video above are a help to control elevation though he mentiones to have a mark on the belly of the prod instead a special attachment like with those sporting weapons.
    I would assume sights were common with high quality hunting crossbows, too.

    Sensfelder writes in the book fo the Netherlands Royal Army Museum Collection about some of the crossbows with hints to sights but mostly later ones (18-19th century).

    The thumbthing is quite easy, the point is to make shots as constant as they can be, so with dents (or similar hints) in different positions in your tiller where you can put your thumb in and afterwards laying your cheek on, you can regulate elevation.
    With this bolt length has to be equal, too.

    Greetings Rizzar

    Are there any known photos of these so called notches or dents on any crossbow. Would love to see what they looked like.

    Dents or reference-points for sighting: easiest to find for many 16th century Germanic bows is a dimple in the top of the stock, near the tail. Often it's shaped like a scallop (pilgrim's shell) and sometimes it's even made of inlet ivory. The 1592 bow I referenced earlier has a thin iron plate that shows at the top of the stock... has several little notches on it. I can't think of any other reason for it to be there. Geezer

    Thanks Geezer. So let me see if I am following this right. By placing your thumb in the dent, following the line of sight to the bolt tip, the closer the dent to you the higher the elevation? So was this method used from shooting with the butt of the tiller against the shoulder or atop?

    in all probability, the dimple was used for shooting 'freehand', with the butt of the bow clear of the shoulder. You sight over the bolt-point. For longer ranges, you drop the butt of the stock, rather than raising the point. Does this make sense? Geezer

    Ferdinand- good idea! How would I make a read peep l-r adjustable for windbags when using the tip of the point as a front reference point?

    Ideas or pics? It definitely has me thinking ...

    I made a really easy one on my first bow. The topic should be around somewhere. It works really well, its fast and easy to aim. Currently working on a different one i copied from an existing one that whas posted in this topic from a privat collection. It has 3 points of elevation, folded down thru a groove and up thru a hole in the middle or a nother notch on the top. Once i take out the sideways deveation i practice different distances to see where i am with the three points of elevation.
    I am really exited to go and tune it. But after it is mounted i have to heat up the forge to make bodkin heads. The bolts need to be exactly the same length and weight. I'll post pictures if i can.

    Ferdi, I'd rather shoot the kid in the forehead and say "whoops, sorry." Smile Cool little sight. How did you fabricate that? From sheet steel? Welding or forging?
    BTW, I just picked up a simple flux wire welder last week. Because I have to work outside (workshop is too full of wood and other inflammible things), I opted for this method. it should give me more options for making various components like ticklers, plus I get to wear all that cool protective gear. My wife said I look like a mass murderer with the welding helmet on. Too many horror movies, perhaps.

    Allright! Here goes nothing! This what i came up with. Bolt head is the forward aim point. The hole is for the resetting. Didnt have enough space so had to make do like this.
    Its all forged out off 10mm round bar.

    Slightly off topic, Ferdinand, but how is the decorative bone plate with the black line drawing done on that prod? Looks very nice.

    Hey Kenh!
    Dont think people will mind if i tell u!
    Its imitation ivory wich i engraved with a dremel tool. Some black paint and when its dry a quick sandpaper over the top. The 'ivory' is old domino pieces wich i cut straigt and thin and glued together. Worked fine! Lots of work though, but cost me a buck and a half! The picture i copied from a site.

    Thanx Ferdi. I'm thinking of adding some faux irovy panels to my latest build (see Loose Laminate Pinlock). My faux Ivory is Holly wood (not Hollywood) which is nearly white. Same idea would apply but I'd have to be a bit more careful with the paint...

    Hi, as far as I know the medieval crossbow did not have a sight, the crossbow was aimed using the thumb knuckle on the top of the stock and the point of the bolt as the forward sight. I presume the shooter used aiming points as do longbow archers today, and would know the ranges of their bows through constant practice. When I shoot my longbow barebow style sometimes my sighting point is a marker well below the target for short range.
