This is an overview how I make the 50 cal bullet pen
I use once fired 50 cal brass shells & Tracer rounds (projectiles)
The Draft
001-Drill out incendiary 23/64 bit
002-Melt out lead
003-Drill out projectile point
004-Chamfer inside projectile with 3/16 bit (just a kiss to chamfer)
005-Home made mandrel
006-010-Chuck up mandrel and sand I use 400 and then 600
011-012-Use mandrel to polish, I use a black or brown rough and then a white diamond to finish, Brasso works great as a final polish
013-Clean out inside of projectile
014- Parts laid out
015-Notice 1/4" dowel lower right
016-Glue in 1/8" (plug) into bottom of case receiver
017-Glue in .385 wood w/7mm tube installed after glue dries press in trans.
018-Notice step drill on case receiver, this lets the 7mm tube & trans. slide in without restriction
019-Notice wood receiver is loose in brass case
020-Assemble projectile w/trans into case receiver
021- Check fit – Assembly Projectile & lower case receiver (#020) should fit into brass case. Make adjustments as necessary when satisfied glue in place. To glue add epoxy to the inside of the empty brass case. You want about 1-2ml enough to hold tight but not too much it will overflow when you insert your projectile w/lower case receiver (#020) stand on end and let dry
022-023-Completed pen
All questions and comments wellcome...
Have Fun
