Thread: Earth moving machinery repair recommendations required

Gravity.

They are heavy.

Got a parcel in the mail this morning from LordBug, a good selection of low hydrogen rods to try.

7016, 7018, 4816, & 4916 are what I can see at a quick look.

Just getting around to posting some pics of the repaired grader.
It works like a bought one again, I took it out & did a couple of hours grading with it.

Looks good Cliff, did you use the 35 to tow it?

I have only just seen this thread and I read about the first three posts and then went to page five as I guessed it had all been done and dusted. The first posts nailed it in one (eh...two actually).

Low Hydrogen rods have to be kept dry and preferably hot. Certainly they have to be hot before use (that was why they were sticky when you used them cold). I cook them in the oven or an electric frypan. At work they are kept in a hot oven all the time.

Weld preparation is important. Metal must be squeaky clean. Metal you are welding must be hot (LPG flame or preferably Oxy (you can see the moisture disappear from the metal as you heat it up). You also need a dual voltage welder for low H2 rods as the 70V setting is required (Low H2 rods require an OCV of 67.5 volts).

However, this is all academic as it looks like you have the grader up and running. I would love to have got my hands on one of those towed graders a few years back.

Paul

Nuh, cheap Chinese Appolo, the old Ferg has grader blade on the back, Mum uses it around the house & garden.
