If that was invented with modern sensibilities in mind, it would have been the ‘sirloadalot 2000’ or the ‘armalite tekload’. Gone are the days where you could just call it a bollock dagger because that’s what it looked like.

This lever seems far better for war than a windlass or cranequin crossbow. Loading just seems far faster.

The main difference is you trade speed for power, a windlass or cranequin can load a much heavier crossbow. Probably depends somewhat on your situation if you are defending a castle wall and have good cover speed of fire might matter less than outright power.

Jonathan Wells not true. They were used for sieges in England, since the longbow men dominates English missile troops in the battlefield. In continental Europe, the windlass crossbow was widely used on the battlefield by crossbowmen with a pavis to hide behind and the cranequin crossbow were widely used on horseback, with German ones being over 1000-1200lb, 1500lb max in draw weight.

@@loganjones5766 I have to wonder how much of the advantage cranequin and windlass really had and how much of the preference for them came from placebo, ie. "It's harder to draw therefore it's a better weapon". Although I guess the extra throw weight would be helpful for lobbing heavier bolts better suited to hitting people in armor with a bit more force.

considering how long it used to take to load a musket its a wonder guns ever took off.

The big reason guns took off is because they were really powerful and could penetrate plate, chainmail and gambeson all in one go and basically a common soldier could from a distance kill a knight in full plate without even exposing himself to any risk. The pope even tried to ban the hand cannons of that time because they were overpowered. That is if you could hit something.

The trick is to not really try to reload, you just get a line of men 3 men deep front row kneeling, rear row shooting between the shoulders of the middle row and just fire a single volley and that first volley pretty much wins the fight. Whatever is downrange is reduced to a small fraction of its original strength and utterly disorganised. You won the fight in an instant, there will be some survivors but so few and so disorganised you don't need to reload super quickly. Pre-musket firearms were actually quite quick to reload because they had EXTREMELY loose bores, so loose you could just pour powder down the barrel then just roll a ball freely down the barrel, no ramrod needed. And you didn't even need to ready a flintlock pan, there was quite a large hole in the breech directly exposing the powder charge and a match could be directly touched to it. This was... amazingly inaccurate, hugely varying velocities. Even less accurate than muskets. But they were SO much more powerful than muskets. Muskets were "accurate enough" for a really dense volley and for so much of the time you could just fire a single volley to make them vulnerable to being finished off with a bayonet charge. But muskets had something WAY better than crossbows when it came to taking precise pot shots. Rifled muskets. They had both accuracy and velocity for excellent effective range, way way better than even a windlass crossbow that was as slow if not slower to reload than a rifled musket.

It is a matter of quantity vs quality: longbow men requires years of training and arrows are expensive to make, store, and transport on campaign. Musketeers, on the other hand, requires little training and lead balls and gunpowder are much easier to store and takes less space during transport.

@@quicklot5982, indeed. while the matchlock smoothbores were rather unimpressive in their range, were inaccurate, and were cumbersome, their components (besides the black powder for the propellant) were less vulnerable to weather (unlike bows, catapults, and crossbow prods such as humidity or winter) while easier to train with compared to the first two. What made them effective was the invention of the Pike and Shot formation by the Spanish Tercios (which enabled concentrated firepower via volley fire and defense from calvary with densely packed pike men) in the 15th Century as gunpowder emerged in warfare. From there, the Dutch and the Norwegians modified the composition and density to make it smaller and more flexible. The bayonet replaced the pike by the 17th century and mass production of rifling & the conical Minie ball made bullets gain accuracy at longer ranges by the 18th century

Were there ever goats-foot levers which stayed integral with the crossbow? One could imagine a peg running in a slotted track working just as well. Figure out a way of folding the whole thing out of the way while firing and you have the potential for much faster reloading.

It might be easier to fit the goats foot so the lever is pulled down underneath with the struts and hooks running either side of the wooden frame of the crossbow. That way there isn't a load of stuff on top where you're trying to look and aim.

It’s likely because gaffe levers (a related lever mechanism) are less expensive for target practice. As for hunting crossbows, most use a built-in winch to increase power/range by a factor of 3 at the cost of speed

Great video. To be a bit pedantic: that's a "class 2" lever, with the pin as the fulcrum, so I believe its starting mechanical advantage is about 7:3, not 4:3. (As a thought experiment -- if your hand were on the string, you'd have a 1:1.)

I’d like to see Joergsprave experiment more with these things. Imagine creating a full auto crossbow that uses electric pistons attached directly to one of these goats foot levers via a sliding cam system, so that it automatically charges the bow string back and forth to create automatic fire.

I might be able to adapt it for our springer catapults.

Great video again Tod. What tool are you using to cut the curvatures on the goats foot? I'd imagine I could make one with a hacksaw, belt and spindle sander, and a lot of elbow grease.

So I am thinking about installing a thing like that on my "modern" crossbow with "just" 175 lbs. Maybe you can show us a DIY what is important if I create a goatfoot on my own?

Another good video Tod. Can a crossbow prod be cut out of a leaf spring. Would it hold up and be usefull? Thanks

Hi Tod. Thanks for this! Any idea what the fps, momentum and joules are for that crossbow?

Tod, do you finished the cranequin crossbow for skallagrim ?

I would like to see a comparison in projectiles per minute between a master crossbow archer using one of these and a master marksman using a mussle loaded gun also accuracy comparsion. Would be very interesting also to see how modern a gun you would need to be more efficient than mechanical weapons.

Could you do a video on what happens when you mess up spanning different types of crossbow? I.e. I imagine that goats-foot goes a fair distance!

Todd sell some for 1000+ draw weights@ different draw lengths .maybe 24"

Is it possible to put the lever below the crossbow? Would the operation of the crossbow be more comfortable if the lever and reloading action was below the crossbow?

Where can a person get a high quality cross bow like this?

Hi, Tod! Why don't you rest the butt of the crossbow on the ground and use your both hands (one on the lever and the other on the stirrup), so you can use the weight of your body to help draw a much heavier bow (600 lbs or more)? Isn't plausible?

I do wonder how powerful a bow a professional crossbowmen would have spanned with a goats foot back in the day. 50 years ago nobody thought longbows built for war would better 80-100 lbs. Once they Mary Rose was brought up, it became apparent that was completely incorrect. Could a very strong professional crossbowmen using his bow for a living with a long lever span a bow of 800 lbs? Seems impossible...but then so does shooting 170+ lbs bows, which we know they did! Thanks

A 1.5 tonne bow would be about 3300 lbs. If that thing failed when it was next to your face... They would probably be picking up pieces of your jawbone 20m away.
