[texx]

just downloaded it from the net and saved it transfered it to word made it to the size i wanted without altering the the length to width ratio and printed it out .
ang i'll go get it . hope this works , its on page 3 , i right clicked the diagram and saved it on its own then copy and pasted it into word .

Thanks texx. i will play with that myself and have a go at my own.I am always having to go over to a mates place to use his.

um texx - perhaps you might want to put the arrow on the correct way - the spine (which is the cock feather, the orange one) should be up toward the ceiling not back toward the board.

Looks good mate

bob if you want to play around with that and you enlarge it before printing make sure you enlarge it the same in all directions . if you double clilck and drag it bigger by one side you alter the scale i rekon , what i did was drag in bigger by the corner cos i think that keeps the correct ratio , other thing is no matter how big or small you make it that line "a "that is printed on there is the length that your lever needs to be from the centre of the pivot pin to the centre line of the arrow , thats the way i understand it anyway .

Actually the cock feather should be pointing down so the shaft is bending as it would around the bow when being shot.

Hey texx,

Don't beat yourself up too much, thought I should mention it though, especially if you were to use for other "softer grained" timbers, where the spine will alter significantly - up or down depends if you're left or right handed hey Jeff..... without getting into the keft and the kerf. You will find with Hoop the spine will not vary much feather up or down.

That is not surprising but sometimes there is a difference and that is why I mentioned it.

up or down depends if you're left or right handed hey Jeff.....

Always down for the reason stated above. Left or right handed will make a difference in the direction you have the rift of shaft facing though.
