Welding Tips and Tricks

Here's a few repairs I took on recently - all done with the 1963 Airco
Used up to 230 amps, 2% thoriated 3/32" and 1/8", #7 gas lens and regular cup.

Case, head and a cover for a 72 Triumph 650, 5 speed.
Another engine case and the frame came in later - no pics of those, oops.

The case had some epoxy in the hole for a plug, cut it out and welded and blended.
Cover had a broken out hole, cut it off, ground a bolt down to hold open the oil passage, welded and blended.
Head was in a bad spot - cut the break down 3/4" and used it for a shelf - he will have machine shop finish blend it.
I flat filed this by hand.

Side cover pics.
I inserted a ground down bolt to keep the oil passage open.

The head was difficult, crack was almost 1" down and the torch does not fit.
Cut the broken piece 3/4" down and used it for a shelf to build up on.
He will have the machinist dress it flush or I would have filed it down by hand like the case.
I cut the broken piece down 3/4" to build up from.
That hole only holds 5 ft lbs of torque.

Really nice!!

nice clean work. i have welded
many side covers and getting all the oil
cleaned out of cracks and holes is alway
the hard part.

Oil in engine parts.
Buy a bag of Sweet Martha's Choclate Chip Cookies.
When wife leaves bake engine parts at 300-400* for 3 hrs. remove parts to shop before she returns
When wife gets home hand her the cookies and say you tried to bake but burnt your batch , hand her the cookies/treat and quickly leave for shop.

Alternate method, old BBQ grill, oil migrates out with heat,most oils flash off above 300*

Thanks for the complements guys

As for as oil cleaning, I had him pressure wash the case and cover before bringing it over - no oily residue for me to deal with

The head was pretty clean, just some acetone and it was ready to work on.

anything.

Dishwashers work good as parts washers too

I used to be married, they get worked up over weird things...
Long time ago I had no shop, it was -20 deg F, and the chainsaw needed a head gasket.
So I fixed it on the kitchen table.
Don't know what the fuss was over it - heck, I even put down newspapers

Beware of phosphates in dishwasher soap, it turns alum gray with nasty oxide coating.

As stated beware of significut other after using dishwasher "No sense Of Humor"

My wife has actually said the words, "Would you PLEASE move this transmission, so I can take a bath?"

A related heads up: no reconditioning electrodes in the oven, either.

Least she could have done is left it in the tub and scrubbed it down for you while she was in there

that was kind of her to ask you to remove the trans before she spoiled
the water with funky bath oils rose petals

Yeah, I couldn't convince her that Lucas was a bath oil...
