    Never mind! Figured it out!

    Post by Stonedog on Sun Apr 13, 2014 2:05 pm

    OK, I am at a good spot with the stock....good prod mortise cut....I did cut it at 90* and plan on shimming until I get the string to....just....lay.....on the top of the prod.......

    and there is my dilemma.....

    I am trying to string the prod, off of the stock, so I can check the height of the string against the prod....meaning does it need to be shimmed higher or lower.....

    BUT I CANNOT STRING THE FRIGGIN' PROD!

    I have thought, built stuff, used body weight, cursed, begged, cried, prayed and flipped out....and still no strung prod....

    What am I doing wrong?  

    PLEASE HELP!

    I have one of Slowbow's SB113 prods.....

    How would I determine a correct angle in the prod mortise without stringing it up until the very end!?

    Unless the bow limbs have a large upsweep at the tips,you are not going to be able to get the string to travel parralel to the deck,as the top edge of the bow has to be no higher the the bottom of the bolt flight groove(usually 5/8ths of an inch).There is a simple way to determine the angle,by drawing it full size on cardboard or plywood,but the description is a damn sight harder than the drawing!If you are completely stuck,I'll do it,but basically,you end up with a long shallow right angle triangle.Dropping a line at 90 degrees from the hypoteneuse to the corner of the right angle,will give you the mortice angle.

    Several ways to string an unmounted prod:

    1-Build a stringing help U-Clamps connected by a longer bastard string.

    2-Putting stuff under the tips and clamping the center downwards with a strong screwclamp

    3-Best but most expensive/time consuming is building a spanning device that is multifunctional in use for unmounted and mounted crossbow.

    4-Most exhausting is putting one tip on the ground and bend it with one hand at the center other at top tip

    @ Todd

    It is 200#ish.......

    In fact....I figured out how to do it by looking at an old post of yours using ratchet straps....

    I am going to make a quick prod-like doo-hickey to use!  

    I'll post some pics to show how I did it and the doo-hickey!
