ok...a serving mallet is used to put a "service" on a shroud...which are the lines that hol the mast(s) up ...or to service some other piece of line that you would want to weatherproof...on a piece of 3strand line first it would be "wormed" that is taking a smaller piece of line...usually tarred marline to fit into the grooves where the strands meet.(contlins)this rounds the line out giving it a better shapeand filling in gaps where water could potentially enter.this is done the length of the line to be served.next the linewould be"parceled" that is wrappinh tarred canvas strips with the lay of the line...again for the total lenth being served.thentarred marline is whipped at the spot where the service will begin always going against the lay of the line.then the serving mallet is sat on topof the line at the whipping.the tarred marline is brought around the head of the mallet a couple timesand then aroung the handlethis gives you control on how tight the service is applied by how tightly the handle is gripped.then you start to pass themallet around the line against the lay going the length of the previously wormed and parceled section....when the end is reached the serviced itdone.i will p[ost pics of all of this soon.any questions feel free to ask...
