making an engine plate, hot or cold rolled?

[fishblock]

I need to make a new engine plate to mount my Honda engine to. What kind of sheet metal do I need? I'm finding hot rolled and cold rolled. What do I need? What thickness should I need to mount a gx390? I'm thinking 1/4" thick.

1/2 T6 6061 billet aluminum is what I run. Aside from that, If your going the steel route I'd say 1/4" regular flat stock. Going to be pretty heavy though. Consider Aluminum for parts that large.

I made mine from Hot Rolled 3/16 plenty strong.. Most are made from 1/8"

cut 11/32" slots in it 1.5" long

You can use thinner material if you bend the edges down for strength.

Lighter is faster.

Hot or cold rolled doesn't matter but gernerally hot rolled is cheaper and considered "standard " by most people and is typically what you'll find more common.
It refers to the manufactoring process.
