[CAUT] restrung D

[Willem Blees]

Daniel

Could you explain this method, please. From what you are saying, do 
you heat the top of the bridge pin, and then allow the super glue to 
flow into the wood? How much do you heat the pin? What do you use to 
heat the pin? (soldering iron, I presume). How much epoxy do you apply 
to the pin? 

Thanks
