Subject: [autobodyrestoration] Temporary internal bracing - cheap
I'll be cutting out the rusty floor of the Minor pretty soon and
since it's a unibody, I'm thinking I should brace the inside before
doing so. The braces would stay in place through the sedan to coupe
(roof chop) phase as well.
Square tube and angle are fairly expensive for a retiree, though, so
I'm wondering if I could use thin wall electrical conduit for the
braces after squeezing the ends flat in a vise. Anybody have
experience with that, or know why I shouldn't?
If the conduit is made from a "non-MIGable" metal, I could weld bolts
to the car, drill the flattened conduit, and attach it with a nut and
washer.

Another thing to consider are the zink oxide fumes form welding emt,
thin wall, conduit will make you sick, or worse kill you without proper
ventilation or some outside air sores. . . . get some scrap steel, say
1X1. it's cheep, $.20 / lb. in my area. Joe in Indiana

Thin wall means thin. to much flexing to screw things up. You would be
better off with square wall tubing.

You right about the need for reinforcement,but conduit would be a
poor choice for material.
The fumes,when welding,from the Galvanized coating are poisionous.
The material is soft,it is meant to be formed relatively easy.
If it was flattened,even at the ends,you loose all the strength
except in tension.And the bars are not always loaded in tension.
The success of the whole project relies on the reinforcement holding
the body in the correct shape.At the very minimum,I would recomened
3/4" square steel tube for the majority of the reinforcement.
