When you buy commercial shafting they are spined for a finished 28" arrow with a 125gr point. If the shafts are 32" long and are marked 50#-55# spine they will make an arrow with a 30#-35# effective spine if made full length and have a 125gr point.

Thanks again Pat it's really helpful and I think I get it. If I cut my 32" 50/55# shafts to 28" and have 100g points the arrows should be around the 45/50# mark?

Probably more like 40# to 45#. Points weighing less than 125gr will increase the effective spine weight by 5# per 25gr and decrease by 5# for 25gr over.

Well I made my first arrows and happily found it to be a really simple process. I didn't worry too much about the measurements and glued the fletches on freehand they are not straight but they shoot straight and hard off my bow. I am chuffed- they look good and are more economical. Pictures to follow! :-)
