    First topic message reminder :

    I often hear or read where folks are wanting to improve their crossbow trigger and in particular make the pull smoother and perhaps a bit lighter. And whilst understanding that the loads applied to a crossbow trigger when cocked, can be vastly more than those on a firearm trigger, there are some things that remain constant and are just as applicable to our needs. The following video from Brownell's wonderful website is most informative and provides much insight into how certain parts should operate together.

    Nice Palandjali,

    I like the auto safety.  Is the string latch welded into one piece?  I'm curious about what speeds you are getting and bolt weight?  Also, where did you get your cam design?  Willing to share it Smile
    Thx

    Hi hotspur,Palandjali has presented a number of videos on you tube,but under the name of ll Telvil,most are of crossbow construction,and all share the same construction methods.Others have asked questions similar to yours about his construction methods,he is not very forthcoming unfortunately.I think this is so,because he is eastern European,and his English is not good.All of the bows he builds are compounds,and the videos show a lot,dimensions and other important info...............but...........no information on the cams.He favours old Jeep leaf springs for his bow limbs,I think because they are flat,not curved.Just recently,all his videos under his ll Telvil name have disappeared from you tube,all that is there is the video under his Palandjali name.I would love to build his reverse crossbow,but without the cam info,it is going to be just about impossible.

    Thanks Hermit, I'll have a closer look after work.

    Maybe that opens a more general question of good cam designs. Anyone seen any? I like the idea of the 1/4 inch aluminum plate fab routine. I'll look at reverse engineering some photos of commercial bows.  Or just go circular.

    Thank you for your cam design Palandjali.

    I think Dracula has moved to Canada and gone into politics.

    Hi Pan.
            Thank you for sharing the design and construction of your reverse crossbow with us.I am going to build one.Over many years of working in Engineering,from the machining side,and the repair side,I have seen many inventive and ingenious solutions to engineering problems.In my opinion,you are in a class of your own.You have the ability to look at at what you want to make,reduce it to it's simplest form,and then reproduce it with the minimum of tools,and with the most commonly available materials.This is a gift,one that I wish that I had to the same degree that you do!!.
                                                  So,you come from Transylvania,Dracula was'nt the only person from your area,Vlad the Impaler also came from there.............not a nice man!,but,we are all different,I'm sure you're a nice man,and I don't hold it against you!..............LMAO!
                                 Keep doing what you're doing Pan,you are an inspiration.Oh and nice garden by the way.All the best to you,
                                            Hermit.

    Dracula and Vlad the Impaler are of course one and the same.  And now that you have responded to his letter, The Vampyr feels welcom to visit your home... or at least your web-presence.  Perhaps you should decorate all portals with garlic-buds.  Geezer.

    Here is something that somebody might find useful.
    Asymmetric roller nut

    This one is a plastic furniture wheel, hollow parts filled with epoxy glue to keep anything unwanted sticking there.
    This one is with 90#bow, so the sear is just a glued piece of strip cut from the bands that are used to wrap construction supplies.


    Accurate enough to hunt soup tins from 20 paces.

    The crossbow here is unfinished but fully functional. I like to test my builds thorougly before bothering with looks.

    You know,
    David "Geezer" R. Watson of New World Arbalest,
    I do understand your point.

    And, Mr. David R. Watson,
    -as already pointed in my introductory to this forum- I see myself as a product developer and an inventor rather than a craftsman.
    That is where I can contribute to this community.
    So as far as any possible aestethic considerations are concerned, there is no point to waste my own time or other peoples bandwith documenting and publishing something that would be a rather boring exercise in mediocrity.


    And I may add , Mr. David "Geezer" R. Watson of New World Arbalest, it has indeed been your discouraging and intentionally hostile feedback in multiple occassions, directed to several individuals, that has caused me to adaopt this approach. So you are now just reaping what you have been sowing, Mr. David "Geezer" R. Watson of New World Arbalest.

    Also it should be pointed out to any audience that personally I am not trying to sell here anything.
    I am only publishing a fraction of my work on premise "Information not shared is information lost".

    I have been a member of this forum for a couple of years now,and followed it fairly religiously.I never knew that Geezer's name was David R Watson.I thought that everyone knew that publishing personal information about another person on the internet is a no no,apparently I was wrong.Geezer may very well be unconcerned about having his name published,but I'm sure he wasn't asked,and it shouldn't have happened,smarten up Hullutidemies!

    Indeed I wasn't consulted, but in fact, that is my name and my business name. I've never made a big deal of it here, because I don't regard this forum as a suitable place to advertise my business.  I am happy to share any and all knowledge I possess concerning the making and history of crossbows.  Geezer-mostly unconcerned.

    Yeah, it still stands up well for looks, but in fact there are broken links and I need to make some price/item changes.  I've got a friend looking into that, what i know about websites could be engraved on the head of a pin... with a jackhammer.  Geezer.

    Edstuff: You learn by doing,  40 years ago, I bought an old Powermaster crossbow that didn't work right, so I bought Payne Gallwey's book to make changes.  I got hooked.  Didn't learn very fast, but was too stubborn to give up. Geezer.
