A Buffet R13 Bb clarinet that I recently put 3 tone hole inserts into.
Here's the process from the start to finish including some close-up shots of the tools I use to shape, blend and ream the inserts to completion.
I'm pretty happy with the way this one came out so I thought I'd add it to the portfolio.
On the bench: An older (I believe?) generation Yamaha Duett model top joint.
I was unable to get a decent picture inside the bore but these seem to be a revision just before the current 2018 cataloged offering Duett models with the full bore liner.
This particular joint has the usual tone hole inserts from top to bottom but with the addition of a bore liner from the reedwell to the trill key tone holes only.
Sticking A key -- Ab / Bb trill arm quick fix.
It seems I'm answering this question more and more so I figured I'd make a quick 4-part 'QUICK FIX' photo series.
The Ab / Bb trill arm eventually gets sluggish and causes the A key to stick down or be delayed in returning to the default (open) position. Adding more spring tension fixes it temporarily but eventually the problem becomes exacerbated and unpredictable.
Loree oboes seem to exhibit this problem a bit more often than others (due to the key design) but nearly every brand of oboe I've worked on has had this issue at some point.
The proximity of the trill arm to the key plate can allow the ingress of finger gunk, hand lotion, cork grease, etc underneath the arm. Once the gunk reaches the key cork underneath the trill arm, it gunks-up (technical term) and counteracts the extremely light spring tension on the a-key which causes it to stick.
Pic 1 -- Pull off these key components and accompanying rod, clean the rod and ends of the key components. A paper / shop towel works fine for this.
Pic 2 -- Use a cotton swab and some rubbing alcohol to carefully clean off the bearing surface of this key cork underneath the trill arm.
Pic 3 -- Use a cotton swab and some rubbing alcohol to carefully clean off the polished pin on the A-key.
Pic 4 -- Re-assemble the key components ensuring that the spring on the tenon end of the instrument gets re-positioned into the spring slot on the bottom key component. It goes INTO the slot, not above it and not below it.

One thing I can say for sure...the DOD (Department of Defense) sure doesn't skimp on equipment.
12,000 US doll-hairs will put one of these bad boys in your pocket (and hopefully not on my bench).
