Test of 4.8x15mm grip in bulk JB-Weld material

Cured for 36 hours at room temperature

minimal deformation

rivet pulled out - this test will be repeated removing the rivet with minimal force by reboring out the interior. However banded contact still evident, as when set in aluminium, implying minimal deformation of the JB-Weld against the setting forces

rivet interior bored out with #12 chucking reamer

banded contact still evident
