The Build
1. According to your drill choke cone dia
(in my case it was a 16mm cone)
do a hole at the center of each piece onto the marked line
about 0.50~1.00mm bigger than the cone dia.
2. Use a combination of appropriated drill bits
and make the two holes at the desirable dia.
e.g.: Ø6, 10, 13 & 16.5 mm for an Ø16mm cone.
3. Remove/cut the marked areas
and then separate the two pieces from flat bar.
4. Using an angle grinder make each end wedge like the photo.
