You fall back on the 'accepted practices' rule.

'Gauge' as applied to SEAMLESS TUBING was usually defined as follows:

11ga = .125" wall thickness
13ga = .093"
16ga = .063"
18ga = .047"
20ga = .035"
22ga = .028"

As applied to your situation, you would select tubing having a wall
thickness of .047" for the repair.

-------------------------------------------------------------------------

The table offered above does NOT agree with various gauge-vs-thickness
charts in several particulars; some list 12ga as equal to .093 and
18ga is often shown as .050. Unfortunetely, many historic definitions
of seamless tubing pre-date the availability of SAE 4130 and cite
diameter & wall for MILD STEEL tubing that is no longer available, such
as half-inch x .0375" wall (ie, '20 ga' according to a seamless tubing
manufacturer of that era).

Just for the record, that's Thanks, VeeDubber...


no it is thanks - mike
mike was the guy saying thanks.
perfectly plain to me. ....and no doubt veedubber and mike.
if you do a search and replace to put a newline in place of the
hyphen I'm sure the penny will drop for you as well.
