    Hello all! after much lurking and research in preparation for my first crossbow build, i decided to register and introduce myself! 

    First, a little about me. I work as a blacksmith/ whitesmith and many other things at my job restoring and reproducing 17th century hardware. As a hobby in my spare time i am also a bladesmith. I am a fast learner, and good with my hands, which has allowed me to pick up new skills very readily. I have never had any official training besides just "doing it" and research. 

    A few months ago i saw a mini 4" crossbow online and said, "hey thats cool.. i bet i can do that." So i did, and now.. now i want to build a medieval styled full size bow. 

    I picked up a 3x3x3 red oak board at Lowes, and after much research i started on it this past Friday. I am planning on making a crossbow at around a 200 + lb draw, as i want to take it out hunting eventually. So far I have the roller nut and its reinforced socket built and set almost flush into the red oak post. I also have the trigger lever slot drilled, the lever set in place and tested the whole thing for functionality. I need to mill the slot for the bolt to rest in and i may trim the sides back so the tiller is not so wide. After that, i plan on purchasing the prod and bow irons. I could make them, but i figured for my first crossbow i would rather be safe than sorry, and get it professionally done. On that note, I was planning on ordering the parts from alchem, are they still in business?

    Sorry for such a large introduction, I hope to learn a lot from everyone here as i progress with this project! Hope you all have a good evening. I shall finish this up with the few pictures i have so far.

    Welcome to our wacky world!

    Great looking beginning.  Is that roller nut assembly milled from aluminum?  I've heard there can be problems with aluminum 'sticking'.  You want want to Search here and see what has been written.

    I have to say I admire the heck out of any metalworker... just not something I ever had the opportunity to learn.  I'm a woodworker, myself.

    AFAIK, Alchem is still in business -- slow but still in business.

    Certainly that 3x3 can be shaped to reduce half the mass, at least, while retaining all the needed strength.

    It is entirely mild steel actually. I basically followed the guidelines on the wiki, then milled the mug welds off nice and clean. I have been debating on switching out the mild steel nut for a delrin one. What I will probably do is make one of delrin and test the both out when this thing is completed. 

    And thank you! I admire all woodworkers, working with a chisel scares me. After getting used to working steel wood seems to move entirely too easily.

    Hello all! I finally received my prod from alchem, so I am now ready to continue this project. Before I do so however, I have a question. I just now realized that since I used 2.5 x 2.5 square oak, once I cut my slot for the prod I will only have 3/8" of wood remaining above and below the prod. Is this going to be a safety issue?

    3/8 in. top and bottom should be just fine.  That's what I use.  Geezer.

    So I have some work done! The wood has been cut and shaped, and I am now fitting the prod to its space. 




    I have also read somewhere that it may be a good idea to put a reinforcing screw or bolt to protect against the bow irons splitting the tiller. Is this just a large screw or carriage bolt run up from the bottom behind the wedges?

    Most period bows with bow irons had a rivet between the prod and bow irons (about halfway) from bottom to top. I use a lag bolt for that purpose, being careful to avoid having it show at the top.  Period Rivets did show at the top.  Geezer

    Ok, so I will thread a bolt in there next time I work on this. Thank you for the quick response!
