Cutters
Roof
A sagging roof on the shop equipment welding (SEW) trailer can let water, snow, and
ice collect, which eventually leads to leaks. A T-bracket can prevent sagging. Here’s how
to make the bracket:
You’ll need a tape measure or square, a hacksaw or reciprocating saw, a grinder and
welding equipment. These are all part of the SEW. The bracket can be welded with any
process, but shielded metal arc welding (SMAW) or gas metal arc welding (GMAW)/flux
core arc welding (FCAW) are the fastest.
You’ll also need two feet of 1

-in angle iron.
To make the bracket, ±rst open the back doors and roof of the SEW. Make sure the rear
stabilizer legs are deployed. Have someone stand underneath the rear cross-member of
the square roof attachment frame and push up the roof as far as they can.
Measure the distance from the roof to the top of the square roof attachment frame.
Take this measurement and add 1

inches (for example, 3
