spine jig

[ozzy]

g'day all

have a question,i bought a spine jig off keith forrester on here(good product i recommend it)but the question is the jig is AMO which is 2lb @26 the jig is 26.8 inches...in the scheme of things would the .8 of an inch make a difference to the spine reading ...if so how would i calculate to be the spine at 26''

if you get what i mean

cheers mick

Mick,

Keith's jig was meant to to have the supports 27 inches apart. To match your spine readings to the AMO just lighten your 2lb weight to .894 grams and all will be sweet as they say.

thanks jeff

mate is that take off .894 grams to weigh 1.106lb or the weight is .894grams just making sure i read it right

been out of the trad for a bit(been concentrating on trapping foxes for a bit now)and setting up my curve again but not happy with the arrows im using so looking for a better set up it goes 50lb@28 smaick phantom recurve my draw is 25.5"(45lb by my draw)150gr tuskers with 49gr wood screw inserts on 50/55 sitka shafts

Make your weight 894 grams. I inadvertently put a decimal point in front of the 894 in my above post as I was thinking kgs. A 2lb weight is 907 grams I think. From memory Keith's jig would read about two to three pounds light with a 2lb weight.

With your set up you may find 45/50 pound spine arras to be enough. All the best with getting things sorted.
