They are easy to crush once you begin to make a cavity.
The plastic smells like Bakelite which makes me wonder. The foils and insulators are not inserted in the tube like I am doing but it appears that the tube was molded around them. If it is Bakelite they must have had to heat up the whole assembly. Maybe this accounts for the poor performance. Either the insulator is damaged in construction or it is a material that can stand up to heat - but not years of service. When I drill it out it is just flakes.
