    Post by ferdinand on Thu May 31, 2012 11:36 am

    First topic message reminder :

    First steps towards a new build. Getting the angles correct on the parts to make it all work together whas kinda tricky. But i think it worked out. Next i have to clean them up and harden te surfaces to reduce wear, any ideas how to harden them? heating to redhot and cooling in oil sufficient? i made a short movie to show how it works. MAc, thanks for the picture of the 4 axel trigger assembly, i decided to keep it a bit simpler but it is basically the same.

    Its actually not sideplates! I made it go al the way around the underside!
    Made a template out of paper, not the best job actually, but will do for now. One more metal plate for the top and that is finished!
    Test fitted the prod yesterday! Looking good! Needs some tinkering and binding.
    Dont worry about who finishes first, its not a race!

    Okay, so i couldnt help tinkering a bit to get a overall vieuw of what the hell i'm making!

    The prod is nearly finished, didnt end up rolling the ends.... i know, a bit weak not to do it after asking so much questions to everyone! thruth is i got a little scared of serious injuries, the prod is going up to 350lbs and i've never attempted something that heavy! This thing will be armour piercing strenght! Fortunatly the string on my old bow is the exact right length. I will be making a real one out of string to use for shooting.

    Next up is the bridle part, need a saddle to mount the prod and came up with the idea to give it a lions head in the center, nice touch!

    But tell me, dont u think it looks a little bit more like Animal from the Muppets?

    Looks good, but you might want to consider a safety strap on the prod. i got a 800lb+ prod on mine and i used some thick belt leather for a safety strap. You could say i was a bit nervous when i first drew it to full draw and managed to jam the cranequin. i got the cranequin off, but i had to take it apart under tension and accidentaly shot the ratchet bar through the door of my microwave.

    Exactly my point! I plan to span it with a goatsfoot or something alike. A cranequin is a bit much for me i think, that would take me quite a while to make! Though it is temting!!

    Hey Ferdinand, looks great so far!

    Remember calculations for draw weight was just a rough data!
    With my first prod from my own production I had a lower force output than calculated because the limb forces work in different directions.

    If you could try to measure the force it would help me with my calculations.

    Or for example, when you put the bow on the ground step with your feet inside and pull on the string near to draw you can get a clue it is in the 90-110kg range.

    Safety strap is my recommendation, too.

    p.s.: i think still it is a pity to cover this crossbow with the steel plates.

    A little help needed before i start the bridle part!
    As u can see on the top picture were te prod is in the tiller the string rests quite heavy on the tiller. Should i increase the angle of the blade in the tiller so it drags a little at the end or slightly slong the whole stroke of the string? Excuse my english, hope u understand what i mean.

    Hey Ferdinand.

    You should place the prod in the tiller in a position when your string is in perfect nut position at full draw so it slightly touches the tiller.

    Your prod has no string elevation, so there will always be more friction loss than with an elevated prod.

    The closer the string moves during shot to the prod, the more friction will lift the string and it will in the end look very elevated when the low tension string rests at bracing height.

    Be careful when determining the installation angle, a too big one will cause misfire.
    I wrote a topic how to determine the angle via google sketchup, but if you dont want to do it with cad you can use that methot with pen and paper, too.
    http://thearbalistguild.forumotion.com/t796-prod-installation-angle-determination-via-google-sketchup

    As for your lion head bridle wood, don´t you want to apply a stirrup or at least an iron loop?

    Thanks again! I was planning to mount it with a little drag at arace height but i see now what u mean by misfire, the string might hop the bolt right?! And for the saddle, i wasnt planning to make a stirrup or ring. Maybe i'll try tomake a cranequin or goatsfoot.

    This build is getting better and better, Ferdi. I was hopping around at first, but then sat down to read through thoroughly...Haha!! you actually managed to form the metal around the stock! I used the paper template too in one of my projects...eyed it out and got lucky, but when attempting to repeat it found out that luck can be quite illusive.

    Keep up the good stuff Ferdi! Very Happy

    I am that 'one time lucky' kinda guy! Never attempt things like that twice, wont work! Haha. We ar cursed!
    Thanks for the positive reaction to the metal, gettin some mixed reactions. I am still asking myself if i really want to keep it.
    But, first things first. The bridle is next, first time so it will probably work out fine! Haha! Damn hard work i must add, damn my hand hurt after a few ours tinkering!
    Thanks for the support, i'll be back.

    Question.:
    If i plan to use hemp string for the bridle wich i make wet before use so it is nice and tight when it gets dry.
    Wil it loosen when i use bee-wax afterwards to conservate the string?
    Or do i wax it first and then make the bridle and let it dry?

    24 string endless loop masonry cord pre waxed with bees-wax. It gives me almost 10mm of thickness, i thought that would be enough, looks a lot like the heavy string on the original crossbow. Any thoughts on my bridle-waxing question?

    I am really proud to present u with my (nearly finnished) Halbe Rustung!! Never guessed it would turn out to be this beautifull....Even if it doesnt fire a single shot or shoots like crap i am still pleased. Last thing to do is finnish the bolt guide in the front and some details on the inlayed flower on one side aswell as a little metalwork, really cant decide what to do, do i take it off? Or leave it on?

    Now to make a goatsfoot or other tool to span it cause damn, this thing has some serious power! And the bolts offcourse!!

    Made two bolts, and added the metal plate to the top. Didnt bolt down the plate as in the original 19th century repair, it just didnt look right. Maybe ill grind down some nuts to make them look old and the put them on. Forgot the arrow-clip, but i made the bolt slightly snug so they dont fall out.

    What an incredible work of art you've made! I am in awe. The lines on the stock are just so sleek and perfect, and I love the overlay you created on the top. I can't believe those are (former) dominos! Wow. It's absolutely stunning. You should be enormously proud of yourself.

    Ferdi! Nice, nice, superb work! The goat's foot lever came out so well, and is a terrfic match to your weapon. I really need to learn how to weld. It seems an essential skill.

    But now for the essential part, does it fire? Looks are great, i must admit being proud! But, as we Dutch say: its no use having a big willy if it dont go up! Is it for show, or .... Couple of hours and i'll know!

    It's been very interesting following your build and the crossbow turned out great, the engraving and inlaying looking top notch.
    Nice work on the lever too, complimets the bow very well.
    I'll be interested to hear how your shooting went too...

    Thanks Taxus!
    Yesterday i took it out and fired my first shots! It held up just fine!
    I had to twist the string one extra time to take the slack out. Nice and powerfull! I accidentaly shot to high and the broadhead pierced the steel roof plate! Glad i didnt use the bodkin head! That would have gone straight thru! Made 3 different bolts, a broadhead, bodkin and a fuerpfeil(fire bolt). But the bodkin shoots best. Made wood fletching, a bit to thick for comfort, i am looking for alternatives.
