Nice !!!

Your welding work makes me want to tear ALL of my rednecking apart for your PRO repairs. 

 I'll be patient though and wait for them to fail or whatever. Way in the future I hope and we will both be on retired street by then.  ;)

Yes I want to fill that in so that it looks like a bow never existed on this saw.   The plan is to fill the entire area with rod and not try and cut out a piece to fit in there.   The casting is pretty thick at that location on the saw and it should make for alot easier welding.  We will see, and I will show before and after pics.

So here is the second part of welding on the 8500 case.   You can see in the before and after pictures that there was a bow on this saw at one time.   I wanted to make look like it never existed.   This was done with a backing material and just ran a bead along the edge unitl it I got it built up.  I did this from both sides so that there would be enough material to shape when done welding.

That is so sweet 3000 FPS.   8) 8)

Some day my 3rd TA will need that fix if I keep it around. Why someone in Ga ran a bow bar on a 3750 is beyond me.

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.

There just no substitute if you're going to repair any alloy of aluminum or mag for a heliarc rig .They try with MIG but often that doesn't cut the mustard .

Steel ,cast iron if you know what you're doing you can stick it or gas it depending .Some stainless can be sticked also depending .

Now like myself .I've got one old Forney buzz box at the house .Two gas engine portables at the shop .One 1940 model adjustable core Lincoln ,a 400 amp Westinghouse retifier,one Dc -MG set  and 3 sets of torchs .Not one freakin heliarc rig so I'm out of the aluminum stuff .--got buddies though --- ;)

You are right Tig is really the only way to go because of the AC setting that you use it on and the precise control of amperage.
