Have you been framing wrong? 🤦 #framing #carpentry #testing

What happens here

After the overcut sample has broken, the presenter carefully removes it and positions the "NOT" (clean-cut) wood piece in the same test frame. The hydraulic pump and jack are again used to apply compressive force to this new sample. The presenter operates the manual pump, gradually increasing the pressure as observed on the gauge. The force is applied until the clean-cut wood piece also reaches its breaking point, failing with a similar splintering action as the previous sample.

Goal: Determine the breaking strength of the clean-cut wood sample.

Tools and materials

  • Hydraulic jack — To exert compressive force onto the wood samples
  • Hydraulic pump Titan Tools — To generate and apply hydraulic pressure to the jack
  • Safety glasses — Protecting eyes from wood splinters
  • Wooden test frame — Holding the test piece securely during pressure application

What they say

Hide

Testing some framing. We got overcut and not overcut. The square cut and the overcut failed at about 2,000 lbs. You don't think it matters for rafters and stairs if you overcut, but let me know what you think.
