6.1.2 Drilling the Chassis
Start by setting the center of each hole to be drilled. A center punch is often
used. Here, a 1/16” drill
bit was used as shown in
the picture.
Use the appropriate drill
bit size as prescribed by
the drill plan.
Here, a unibit was used to drill out the 7/8” hole for the two (2) additional tube
socket holes.
Deburr or countersink
each hole to ensure no
sharp edges will cause
injury or component
failure.
