Hi All,

    John touched on one item I forgot to in my last post. The sprueing is
    very important to investment flaking. If you have a sharp angle on
    your tree to your sprued part the metal can and most times will hit
    that thin poin of investment and break it off. Be sure when you sprue
    to have a smooth rounded junction from the tree to the sprue and from
    the sprue to your part.
