Would one of those soldering tips with the built-in "CUP" or "WELL" work better here? I have been trying to get one for MONTHS with no luck. For example: a popular part is # 900M-T-2CM SHAPE CM (NOT SHAPE "C"). Do you have any idea where to find one? Last time I thought I had one, but when I put in in the shopping cart and tried to purchase the cart items, the reply was that this particular part can't be shipped from the store to the USA!!! HELP!!!
