In my opinion the rebuild kit of wicks and other parts plus the rebuild book being sold on eBay is well worth the cost. The book covers renovation from our current "hobby owner" perspective and offers good practical methods for doing the renovation. I have had my lathe for about 20 years and...

A further description of your symptoms would be helpful to guide a solution. How large is the boiler you are trying to solder...what type of torch are you using?...as others have said copper is an excellent conductor of heat and will pull heat away from a joint very efficiently...isolating...
