    I'll answer your question here then. On the RDT thread Hermit posted this:
    Hermit wrote:Regarding the crossbow string,years ago,when I got into making mine,there was a simple formula which I used and which worked well.Take the bow draw weight(as an example 200lbs.)multiply that by 4(the safety factor)then divide that number by the breaking strain of the string material.Dacron is I believe 50lbs. per strand.Using this formula gives a string thickness of 16 strands.When the string is made,it should be well coated with beeswax.this was done by rubbing the beeswax onto the string,and then rubbing the string with a piece of leather.The friction of the leather on the string creates heat,which melted the beeswax into the string.String maintainance is important if you want to get good service from your string.When you have been using the bow for a while,you should be able to tell from the look of the string when it needs re-waxing,or a good rub to re-melt the beeswax.

    I don't know how to figure the length of string needed. I buy my first string and measure it. That way I know the strands, serving length and length to go with that prod. It is an extra $20 but it works for me.

    Euell,regarding string length,are you intending to buy a prod?,if you are the prod manufacturer or seller will usually be able to sell you a string.If not they can  tell you the string length required.If you intend to make your own string,then you need the brace height(or fistmele)of the bow.When you have that you can string the bow with a bastard string and a homemade fixture until the brace height is obtained.Measuring between the tips of the bow will give the string length.

    Say Hermit thanks for the info on the prod,and string. Where I downloaded the the plans to the crossbow, I'll be ordering the prod,string,roller nut,trigger, and stirrup from them.
