So called hyper recurve limbs perform best on a more deflex riser as they need lower BH in reflexed risers the BH becomes so low as to be impracticable and torsional stability and the effects of the release become more severe . Border produce "deflexed" risers for this reason
there is a major error in this guide .. it says arrows right = weak - correct - but the says LENGTHEN SHAFT = incorrect!!! and vice versa for arrows left . It also says increasing/decreasing point weight. Point weight has minor effects on dynamic sine but major effects on FOC .. to me point...
Just my 10p worth. I set nock height to get best clearance of tail at standard tiller say 5-6mm depending on riser. Then I fine tune bareshaft into vertical group and attitude at impact ( ie nock elevation same as fletched) using small tiller adjustments. The nock height has to give decent...
I shoot recurve sighted and barebow the same expand through and release whilst expanding..The anchor point serves as the clicker . Same bows same kit just no sight or long rod .. which don't affect the draw anyway . also shoot border hex 6.5 and 7.7s the same
I have seen several people on the line using commercial foot marks - small 3-4 " curved plastic markers with a steel pin through.
Anyone know where I can find these please? Quicks used to sell but have stopped.
Yes I could make some - but time is short
I am trying to fine tune for 70 and 90 m and get the highest sight marks .
I use 40# limbs ( wiawis one or KG nexgen) at 29.75" amo draw on 25" riser.
Arrows are VAP 500 or 600 spine tuned by length and point weight bareshaft at 40-70m to fall in centre of fletched groups.
All fine so far...
Hoping to pick the combined brains of the group please.
Trying a new set up riser change same limbs.
Grouping fletched great at 20m inside 3" ring
BUT bareshaft goes left by 4 -6 " and knock is left too.
Walkback tuning from 20m to 30 m fletched arrows go 3" right of 20m group
Can any one help please?
I am resetting a new limb riser combo and am having issues of excessive button contact starting about 140mm out from the nock resulting in abrasion marks to wrap and shaft just before the wrap.
Arrow spine is correct according to charts and tuning .
Has anyone any...
