After I read that post from last night, I thought Miller had a Miller!!! No pun intended!

Was even considering completing all with MiG. Less risk of inclusions.

MIG root you can do downhand. 7018 fill and cap with good cleaning between passes would be best in my opinion. MIG may be cleaner but has more chance for lack of fusion or incomplete penetration at the toes of the weld.

Had considered that so will stay with first thoughts. MiG for base root, 7018 to finish.

In short circuit mode that is one of the problems especially on mass produced stuff where the welders are less experienced. Weld looks good but closer inspection shows it's just sitting on the top or only has fusion on one side.

Well, another week of blowing black boogers!! Made the root passes Top and bottom MiG, followed with 7018, laid in the welds from root to fill across face all 7018 then cleaned up that and the lower flange(for roller) reinstalled side plate welded it ALL 7018 stick. Not the prettiest welds but I am comfortable with what I completed. Roller is back up, upper rollers back on and rear Rail Guards from Donor are on. Decided ENOUGH for today, Beer-thirty

On the top in the last picture you could put 2 or 3 passes side by side instead of a weave.

Was the final pass, root, a single, double then three side by side. Finished that way on most of my wide welds no issues in the past. Center face weld was root, a wider single, a double row then ground down to flat. All the reinforcement face welds were at least three passes, used Well over 5# rods. Know I am not a production welder, thus the welds you see, just a Old Grunt Mekanik that welds on machines as a secondary operation.

Shouldn't have any problems. I'm glad I have a newer 931B without the outside support for the final drives. Would have liked to put new segmented sprocket hub on but didn't have a puller to get sprockets off so welded sprocket rim on. Don't put a lot of hours on it but the sprockets were Berco and didn't have the holes/bosses like the originals for bolting the 300lb. counterweights on. They were cut with a torch so harder to get the bolts to stay tight. I used some Loctite but one still came loose so I torched the bolts off. I don't need the counterweights with the hoe on but could sure use them with the hoe off, especially with a 4 in 1 bucket. It's on the to-do list but not a big priority right now.

A little further where using up pieces in floor getting in my way!! Replaced the Left Idler outer slide bracket and drilled/helicoiled the inner for the tin guards, got the lower rock guards hanging. Have to peel frozen bolts stubs from the remaining backing plates off the donor tractor and swap both the right side idler slide brackets, seals are replaced on the track tensioner pistons. Pretty much giving in on repairing the mounts to rehang the center guard/guide assemblies.

In more ways than One!! Uncle Arthir and I have been having DAILY conversations, usually Screaming at each other. I am wore slick from years of less than adequate tooling, I am NOT helping matters currently as much of my tooling is as worn as I am. Hate to think it but likely my last BIG Project at least last Big Machine project..

I know all of the Ritis boys, and Athir, he de wurst of them all!

I knew a very good welder who had Iritis. Rare and the Dr's. told him if he had any eye problems to get to the hospital immediately to have it checked. Just like if you suspect a welding flash make sure there's nothing in your eye. I just read there's something called Kawasaki syndrome that can be a cause for Iritis. He rode dirt bikes all his life but never a Kawasaki.

I resemble about half the conditions leading to iritis!!! Left eye is better than had been for thirty years, still cannot see well enough to weld with by itself(as in ALL Positions!)

Well right side is assembled, now to surgery of Rear guards to make them fit as all bent to hell and gone. Spent a good thirty five minutes flailing on the bent up RH tins to get them straight enough to suit.

A little side note as to reinstalling the shields. The old Allis style seal systems were not designed for life scrubbing thru dirt and abrasives thus they tin shielded the journals and seal packages. All too many would have a bolt break off or bend one and off they came, little did they realize that gone was worse than bent. This from a couple of old hands I have been around from Cook Tractor at Fulton MO. The solid rear sprocket center units and solid side idlers were set up a little differently and did not need the severity of protection.
