I am new to the forum and to crossbows. i have had the idea of building a crossbow for a number of years but have put it off until now. I'm working on what could be called a hybrid medieval crossbow. i got the bug after seeing an article in a primitive archery mag a few years back. i finished the prod yesterday, spring steel, it pulls somwhere in the 260lbs range. i designed it so that the centerline of the prod allows the string to ride just even with the rail to elemenate string wear. I have a pic on photobucket.
a couple of design questions include: what string material would be best / safest considering the draw weight and that i would like to keep the string diameter to a minimum. the string that i have on there now is only temporary and is made of 6 strands of 1/16th in aircraft cable, i do not plan to shoot with this string but used it only for tillering pourposes.
and secondly; nut size, dimensions. i plan on useing steel for the nut due to the heavy draw.
any advice will be greatly appreaceated.
