1. How hard would be crafting a release nut, when I don't have access to the lathe or hardly to any electric tools right now?
2. What kind of wood would be best for stock? Soft, hard or maybe something inbetween?

Is a release nut frol wood viable at all?
With minimal tools i think you could buy a tin shears, then cut up old soda cand knto sheet metal, cut it into the shape of the crossection of your nut, do this over and over again and then glue them together and sand down the sharp edges.
This is just an idea ivea had now, not sure if its really viable.

1. not hard per se. but you'd need at least some files and a sturdy benchvise. filing takes a lot of time, patience and concentration. the dangerous part is that it's soo fucking boring that your mind wanders off, and then mistakes happen

2. i'd go with hardwood for obvious reasons

what are you planning on using as a rope? i often thought about diy a crossbow out of some leaf springs but thought the rope will be the weak link

you can make pretty much every metal part with some hand files and enough time. here, a historic trigger that is somewhat simpler than a rolling nut: https://youtu.be/K-ogGdXTGkM?t=877

How does it feel, being allowed to board a plane, normie?
But fun fact:
My dad had pic related as a wee lad, so I got it when I was a kid. Had full instructions for a crossbow (bow from a composite of thin strips of wood, worked really well, no metal parts at all, except for the bolt the trigger was moving on, if you’d replace that with some plastics, it’s TSA approved). So naturally, we built it. Took some thick (20cm?) XPS as target and the bolt just went right through.
Now that I’ve got kids, I wanted to have to book too, but turns out it got lost.
So I bough a “new” one. Turns out they removed the crossbow in the 1965 edition.
Guess it was a really good crossbow.

OP here
>>2894250
Yeah, thought so the files are my only way currently. I got many little files for metal and vise large enough I think.
>what are you planning on using as a rope?
picrel not related. Just the first crossbow pic I stumbled upon kek. I have no plans to use rope.
More like the crossbow from this video https://www.youtube.com/watch?v=3R4zNBV1Kos&list=PLuz1Pc8ogrySIh3QtOJsd_Bkm7ZkdOVfx&index=42
>i'd go with hardwood for obvious reasons
Was just wondering if I'd use softer wood, it won't split in half like oak sometimes does.

Where I live, crossbow needa a license, and it's tougher to obtain than firearm license, because you have to put a reason why. "for fun and target shooting in the garden" isn't a reason for the clerks.
I just don't give a shit.

yeah i was just thinking it's pointless if the bow pulling back level thing is not attached to the bow itself because then its slower to load than regular bows which can mog crossbows in range if the arrow is crafted well

>> No.2895171

>>2895007
Yeah basically just a metal chukonu. Just like the historic chukonu it is in truth somewhat of a meme weapon. Accuracy is terrible because bolts are not fletched. Much much weaker than a regular crossbow. As it turns out this is why it was common practice for the Chinese to use poisoned bolts.
I did have some plans to make improvements to both power and accuracy along with a few other bells and whistles like interchangeable spring fed magazines. Ultimately I ended up putting these plans on indefinite hold to work on another project.

plenty of release nuts were made from antler, so dont really need a lathe - its more needing to get the pawls angled right so you dont risk slippage.
a round, and a tri-square file are sufficient.

Maple is excellent for stocks, Ash is fine but open grained so gets grubby easier.

I'd assume the "fenders" are there to be removed for access to the trigger mechanism.

The bolt (xbow arrow) sits in the middle channel.

The roller in the middle will have a slot to hold the string. When you draw the string back it will rotate the catch and secure the string. The trigger would then release whatever mechanism holds the roller thing in place.

does it just loosely sit there or snap in place what if you flip the bow upside down

Loosely sit there. If you flip the crossbow upside down it will fall out.

bolt is in brown, string in yellow, and i hope the rest of the mechanism is obvious. i always used this as a kid because it's very easy to make; just two pieces of metal with a hole drilled through instead of having to make a proper nut
it's obviously not ideal as the string isn't even in contact with the bolt, so i wouldn't recommend this if you want to do this properly. but if you're happy with something easy and "good enough", i think it's viable. still better than having to push the string with a load of friction like in >>2895909. and in a way you have a double lever (green and red part) so you don't need much force to pull the trigger, less than with a regular nut, where the force of the string is roughly the same as on the part where the nut and trigger make contact. i guess you can just make the lever here longer but it's going to be a lot longer for the same trigger pull force
anyway, i only know half what i'm talking about. take my post with a big grain of salt

you're supposed to just hold down the base of the bolt with your thumb and the string shouldnt hit it, but if you're worried then wear leather gloves, which you should do anyways because there are far worse injuries a crossbow like that can deal to your hands

>1. How hard would be crafting a release nut, when I don't have access to the lathe or hardly to any electric tools right now?
Simple, separate you design into three layers, cut them from plywood or metal (depending on draw weight) and glue or rivet them together. a lathe wouldn't help with this in either case, since there's no rotational symmetry except for the cylinder you start from.
>What kind of wood would be best for stock? Soft, hard or maybe something inbetween?
Doesn't really matter. You need wood that won't splinter, and enough of it that it won't flex to much when the bow is drawn. I've seen people use beech (laminated plywood, around 8cm thick) and ash (carved from one piece, around 7cm thick).
