Jamie, Thank you, the syringa has a fairly large pith center. The nocks aren't footed but rather have turned tip that inserts into the pith cavity. Dave showed me the trick of cutting a squared peice,then just chucking it in a drill and using a grinder to turn a tip on one end to insert into the syninga. It's real easy and quick but I'll let him explain a little better in His buildalong.
Thanks Justin: I still got alot to learn on the arrows. Keenan
