My wife loves her old Lawn Boy push mower; it's very lightweight (esp.
since I removed all the Rube Goldberg self-propelled mechanism) and
easy to start - still! However, the magnesium deck has developed a
crack that runs across the front of the discharge chute. I was going
to bolt a metal plate across the crack as a repair, but it would be a
really sloppy patch.

The more I look at it, the more I want to weld it, but I know what Mg
does when it gets hot enough to burn! Is there a way to do a decent
join without destroying the mower? I only have a Lincoln tombstone AC
welder, a cheapo HF DC Tig, and O/A gas setup. I also still have some

1. Call LawnBoy (or get on the Interwebs) and see if you can get a
new deck casting, and move the motor and all the other parts over.

https://www.shoplawnboy.com/Comergen...ineModelLookup

1A. But first, do a financial study - the replacement deck part might
cost you more than a brand new mower, and you get a zero-hour engine,
new blade, etc. for that price.

The MSRP for the Manual Push model is $259, and if you can't beat that
price by quite a bit you aren't trying very hard.

2. Find a local Aluminum Casting foundry. and take them the stripped
bare mower deck casting to use as a casting blank - they'll probably
want you to fill in the crack with Bondo and fill in any drilled and
tapped holes that you'll need to drill and tap yourself on the new
casting.

It will weigh a bit more in an AL Casting Alloy rather than Magnesium,
it will be a little rough from the sand-casting (unless you spend a
lot more to make an injection mold like Lawn-Boy did) and it will Not
be cheap (it would be certifiably insane 10X the price of a new mower)
- but it'll work.

Besides that, it ain't magnesium. It's "Elektron Alloy", or more simply,
a mixture of magnesium and aluminum (typically in a 35-65 to 50-50 ratio)
called "magnalium".

The same stuff was used for Porshe and VW (and Karmann) gear cases for a
time. When I was a volunteer fireman, I witnessed a co-worker from the
radio station where I was working burned alive in a Karmann Ghia that had
such a gear case.

In _any_ case, magnalium is highly combustible in air. We use it in the
pyro trade as a fuel for raising the combustion temperature of 'bright'
color compositions. Use an inert gas to shield it, and enough so it
cools below yellow heat before the gas shield leaves the zone.

Well, I am unable to find any new Lawn Boy 2-cycle mowers. Every
4-stroke mower I have owned weighs a great deal more than this old
machine. Since we end up picking it up to mow raised areas, weight is
important enough to make this a "must repair". Spending the money for
a new deck is not in the picture, either.

You are right about her being a keeper, so if she says this mower need

We also have a Wheel Horse, but need the pusher for tight spots. OTOH,
we are looking into getting a ZTR to replace the Horse. I tried to
talk her into letting me use the finish mower I have for my 4WD
Mitsubishi, but she won't let that beast anywhere on her lawn -

This Lawn Boy is a 1975 model, BTW. They don't make 'em like that

Yup... just lotsa-lotsa inert gas and a low enough amperage so that you
can have the weldment cool enough before leaving the gas shield.

Magnesium is fine for welding magnalium; though not quite as strong.

The aluminum was originally added simply because magnesium alone doesn't
pressure-cast very well without crystallizing (fractures), and doesn't
have the tensile strength of magnalium. The aluminum makes the mix more
plastic.

I've made a similar pitch to Angie, but to no avail. I guess it's the
English part of her heritage.

Not as bad, though, as when I used to tell her to stop wearing herself
out raking the damn leaves. I would say "They call them 'leaves'
because you're supposed to *leave* them alone." I used that line one
too many times. Now I just shrug.

Lest anyone think I just lay around the house, I do all the
maintenance work on all equipment (I call it "work" when Angie is
around), run the bush hog, cut down trees, then cut up trees (the 2
jobs seem to be at odds with one another), dig holes, build
greenhouses, etc, etc. I'm getting worn out just thinking about it.

FWIW, we had a Sears/Power Products mower with a mag-alloy housing
that my dad bought in 1959. It was light as a feather and I loved it.
He got a newer mower but I would only use the light one. It had a
2-stroke PP motor with an aluminum cylinder, with no lining, and an
integral head that didn't come off. No throttle and a wrap-on rope
starter.

In 1962 - I remember the day -- I hit a rock that flew forward and
cracked the front of the housing nearly off. It was held on by a thin
steel "comb" on the front of the housing, which was held to the
housing with two or three rivets.

When I read about your situation I nearly fell off my chair. It sounds
like the same thing.

Anyway, my dad cut a strip of 1/8" aluminum about two inches wide, the
langth of the crack, drilled holes, and screwed through the housing
into the aluminum. It clogged easily if the grass was wet but we used
it like that for another two years.

'Hope you can keep it.

Jon, all that's been discussed before in this thread.

Both sides of the work must be shielded until the Mg is well below yellow
