**Warning: Lots of pics in this thread**
I used to post a lot of work in progress pics for my builds. Never done one here on ECF so here's how I make a titanium rba cap & drip tip. The Ti is 6Al4V alloy (aka Grade 5).
There's a lot that I left out & did not take pics of, setup, indicating, chamfering, etc.
Cap:
Starting with the lathe....
Facing (to square the end)
Center drill (to start a hole for drilling)
Drilling all the way through for the entire length of the cap.
Drilling with a larger bit for the chamber but not all the way through.
Boring out the chamber to depth.
Turning down the OD.
Grooving
Onto the mill.....
Milling the flutes using a ball end mill & super spacer (indexer)
While it's indexed, I drill the air hole before removing the work piece so the air hole is spot on in between the flutes & in a groove.
Done with the mill.
Back to the lathe....
Final boring for the chamber along with chamfering for the end,grooves, & final finishing.
Wrapped in tape to protect the finish, this operation is called parting off.
Almost done.
Facing to clean up from parting off & to turn down to final length.
Boring to final size for the drip tip & chamfer.
Last op, machining a taper for the top of the cap.
All done!
Drip Tip:
I forgot to take more pics, I was tired & you guys are probably sick of me by now if you even made it this far in this post.
Faced, drilled, countersunk, & machined all the tapers.
Grooving for the oring.
All done!
Thanks for looking & hope you enjoyed seeing some machining if you've never seen it before.
