Chainsaw Repair

So I have this Poulan 3700 with a broken handle.  I weld it up get it looking real nice put it on the saw and get all the screws in except for the one that goes to the antivibe.   I put it in last and I am cranking down on it and I hear this loud snap.  I look down and I **** the handle again except it was only on the top and not on the bottom.  So I decided to weld it again with it in place.  I then take it back off and finish it up once again.  I did not do such a nice finish the second time around but when I put it back on no more problems.  It will just have to do for now.  I got to impatient with it.
