Hi Greg, Regarding the remetaling,
they are done separately the cop and rod so you need only have half a jig,
will try and explain how it is done make the jig so it will clamp in a vice say on a 100x100 mm angle iron
looking down from the top you will have a 50x 10mm plate at the back standing up to this you bolt a half round probably around 28mm for the core you then need to machine to half discs that locate the rod in place allowing for metal to form the two thrust faces the rod and cap at this stage will be horizontal so the metal is poured in from the top.
Next you will need two melting pots that will keep a steady temp,
one for the white metal and one pure tin
also tinning powder
the process is
melt the old metal out of the rod and cap clean the surfaces to be metaled
then heat them an rub in the tinning powder till you have a complete film
then dip them into the hot tin then straight into the jig which has been preheated
then using a small ladle with a spout slowly pour in the metal and using a small rod to make sure that it is not leaving air pockets
Hope this is of some help
