    aluminum prod

    Found an aluminum bow/prod to use in my build. I seems to be a 28 1/2, what size string and where can I find a good one.

    I make my strings for aluminum prods from Dacron B50.  Most are simple continuous loops, about 30 strands.  Length, 27 inches measured from inside the nocks. Assuming this is one of the standard 70 lb. aluminum prods, you could probably get away with 24 strands for best performance.  Medieval bowstrings were generally quite thick (they used hemp for much stronger bows) If you want your string to look like a medieval one, you could go as thick as 50 strands with no problems.  Geezer

    Thanks so much for the advice on the alum nut and the prod. The prod came from an old yard sale Jayco. Know anything about these? They seem to have been popular in the 60s.

    Jayco is probably the skuccessor to old Jayhawk Archery from Afton Oklahoma.  I used to buy my aluminum prods from Jayhak and evenually even talked them into leaving the hole out of the center of the prod (a definite weak point) All the 28 1/2  inch aluminum prods you see on the market are derived from the Jayhawk prod.

    As a side note: there's a good economic reason all those aluminum prods are 28.8 inches in length.  Aluminum sheet comes in 48 X 144 inch sheets.  So a sheet is impossible for most people to handle.  However, if you cut that sheet down into 10 pieces 24 X 28.8 inches, it's easy to handle in a small shop.  One 28 X 24 inch piece will make about a dozen prods (maybe 13 if you're careful) And they can be cut on an ordinary bandsaw, given a metal cutting blade and plenty of lubrication.  So it's possible to make your own aluminum prods in a modest shop.  For a number of years I made my own aluminum prods (7075-t6 alloy, 3/16 inch. thick) Nowadays I just buy them from Darkwood Armory and save myself the trouble  Geezer.
