Looking for guidance in swing weighting a new set of irons (which have hosel weight ports), using graphite iron shafts which will not accommodate tip weights (core too narrow).  I really don’t want to tamper with the shaft core … particularly when there’s a weight port already available.

Is there a good, secure way to add tungsten powder to the hosel port?

Can I just add the powder and cap it off with epoxy?  Or make a sludge of epoxy/tungsten mix?

Thanks for any direction provided!
