    Newb stirrup/irons question

    Post by Armymedic.2 on Thu Jul 30, 2015 12:51 pm

    This will seem a dumb question so i apologize in advance 

    Im blacksmithing the parts for my first crossbow. I cant seem to wrap my head around the stirrup and irons relationship. They are seperate pieces but they need to be linked together by the irons yes?   The irons are obviously solid, and so it seems the stirrup is as well once riveted together at the front.  Im considering completing the stirrup and the  welding it closed with the irons already threaded on loose so it will be a chain of sorts.  Of should i leave a gap in the stirrup with just enough space to slip the irons off where it would be pushed against the prod. I worry that would cause small pressure points.   And im not a fan of rivets so looking to avoid   Riveting the front of the stirrup. Thanks in advance for your time!

    Save yourself a lot of trouble thread and bolt the stirrup's foot-plate in place. You can do it like Payne-Gallwey says, just thread the bits that he would have you rivet in place.  Then you can take it all apart... or you could get a set of Alchem or Slo-Bows bow-irons and let them do the work.

    Thanks geezer i was hoping you would chime in.   Im definitely looking to make the parts in my forge as that is my primary hobby/ job necessity.   Just wasnt quite sure on what was the right thing to do.   How does on achieve the continous stirrup look if not joined at the prod area?

    When I make stirrups for bow-iron bows, I make them with 3/4 by 1/16 inch flat stock.  I turn the upper ends over, thru-drill and tap, to place a separate piece for the foot plate.  Like PG, except using ordinary mild-steel flat stock.  It doesn't look as elegant, but passes tolerably well.  The other alternative is to do what Alchem/slowbows does.  They reverse the stirrup, leaving the foot-plate and sides in one piece, to hook onto the bow-irons.  The important point is: the stirrup and fore-end and keepers at the rear end of bow-irons serve to keep the irons from spreading and slipping off with repeated shooting. Of course you could simply keep the front of the bow-irons in place with a small keeper-clip at the front so they don't spread, and just rivet a stirrup to the bottom of the stock.  It should work just fine, except I've never seen it done that way on a period piece. Geezer.

    Ahhhhhhaaaaaaaaaaaaa.    Ya see this is why i ask questions even though they may seem si ple enough to figure out.   The fact that the stirrup helps keep the irons in place never occurre to me.    Thank you for the well thought out response geezer.   Much was learned

    Yes:  Payne Gallwey's system holds the outer end of the irons in place very tightly, but it's a fairly critical fit.  Alchem/slowbows stirrup uses the springiness of the stirrup, fitted into little notches in the bow-irons to keep the irons in place.  Its a good system, and can be adjusted as need-be to fit the width of the stock at the fore-end.  If you look at their standard stirrup, delivered flat, it has notches cut in the right places to facilitate bending.  They hook nicely under the front of the bow-irons.  Good engineering all around.  I do not know if period stirrups were ever fitted alchem/slobows way, but it's a good solution for sales to hobbyists, and it looks great.  Geezer.

    It makes a lot of sense. And i know just the grooves in the flAt stirrup you mean.  So as long as the sides of the stirrup are the same width as tthe forend, all is well.  And the keeper handles it in the rear   Very cool stuff

    That's the thing about Medieval design.  It's usually very simple and well conceived.  Of course we don't really know if Alchem/slobows innovations are period, but they're pretty much consistent, design-wise.  Geezer.
