Hand tools and shop orientation · Lesson 3 of 4

Hand tools and shop orientation: methods and worked application

A five-step habit for any hand-tool task, worked through with Malco's seamer and snip ratings against AFS catalogue thicknesses, a depth-mark reading, a grip-span check, a shop-air check, and the record to keep.

You will be able to: Apply choose, check, use, return and record to a stated task: compare a maker's decimal capacity with a catalogue thickness, check a tool before use, read a seamer's depth marks, check a grip span and a shop-air reading, and write the record.

Choose, check, use, return, record

This course teaches a five-step habit: choose, check, use, return, record.

Choose a tool its maker rates for your metal at your thickness. Check it before use. Use it with the protection your employer assigns. Return it and tidy up. Record what you used and found.

It is a teaching sequence built from the rules in this module, not an AFS procedure.

Choose, check, use, return, recordA vertical flow of six boxes: read the task, choose, check, use, return, record. Choose and Check are decisions outlined in amber. If the tool is not rated for the metal and thickness, go to another tool or another process; if a check finds a fault, the tool is out of use and reported.Read the taskMetal and thicknesscome from the orderChooseRated by its maker forthis metal and thickness?YesNoAnother tool,or anotherprocessCheckFaults in blades, jaws,pivot, latch or handles?NoYesOut of use,and reportthe faultUseWear the protection youremployer assignsReturnTool back in its place,scrap and floor clearedRecordTask, tool and rating,check result, any defect

Glossary

Depth marks
Graduations on a seamer's jaws, in 1/4 in steps on Malco's forged seamers, that show how far the sheet has entered the jaws so the flange being bent can be read.
Pre-use check
Looking over a tool before each use for the faults that take it out of use: sprung jaws, mushroomed heads, cracked or loose handles, a loose or out-of-adjustment pivot. A tool that fails is reported, not used.
Pivot adjustment
On Midwest snips, a pivot bolt threaded into the bottom blade and secured by a lock nut. Midwest says blades can come out of adjustment after extended use, and that some may think they are dull.
Maker-rated
Within the thickness of a named metal that the tool's maker states for that tool. Comparison is decimal with decimal, for the same metal.
