I had a little better luck tonight, sorry didn't finish the piece or get pictures, but got a long winded phonecall conversation from a friend. will get pictures tomorrow if i can. did still have problems but i didn't try to taper in the bottom by the fuller as much. think i have some usable pieces and suspect the rustiness and quality of the pipe to be part culprit for the issues until i get my hands on some better pipe. I appreciate the ideas guys. IronWolf, i was just trying to flare it out a little for looks not to make the whole thing bigger diameter really, and havn't had much problem there. it's been harder for me to taper the pipe in more at the bottom by the fuller for some reason. and thats when i get the cracks. John B, possibly for that i should be using the straight pein that RT redid for me that has a wider radius but the cracks are happening before hand. as for the rotating on the hits i tried to pay attention to that more this time and actually While fullering it dosn't Look to be twisting it's while i was working the rest that it seems to twist, or atleast show it. i tried to work it like Glenn said and couldn't get the taper before the fullering that i wanted but with flaring and then fullering i did still get a minor twist crack on one. but i also still lightly worked them after for the look.. Ugh.. my bad.. i'm going to try some new pipe and see what i get out of it. it could be this pipe or My working it. i even kept an even heat in between where i fullered on both sides this time thinking i under heated half last time.
