This bottom bow (on Yamaha #2 of a school's four tubas...this is tuba #4) was smushed flat, the small side was flattened, and featured compound creases. The upper bow was fubar beyond my ability to pull my typical rabbits out of my hat...
...so the bottom bow had to come off to repair it's small end and the upper bow, EVEN THOUGH they didn't have the money to properly repair the bottom bow (as only budgeted was repairing the small end of the bow).
Hell... It's just plain stupid (even though no braces on these Yamahas) to remove a bottom bow and ONLY fix the small end, so (yeah) I did some free work.
I generally do NOT quote on replacing these (Japanese...?? Chinese...??) crappy bottom bow caps, as they (dealer) cost more than twice the cost of a Miraphone 186 (far nicer) nickel bottom bow cap...and (as everyone is smart enough to never have a 321 completely restored like new) I almost always try to repair these bows while NOT removing the cap. The soldering is usually so blobby - between the lacquers - on these things, that it's pretty difficult, but it is what it is.
OK...I got this cap area looking marginally so-so...but (again) no charge...and yeah, (after this lunch break) I'll go back and smooth out the easy (single-layer) dents on this bottom bow.
This is a NEW customer...and they need to know that I'm just as interested in customer happiness as I am in revenue. (Our short little lives' purposes are supposed to be to help out each other, yes? I'm certainly no saint, and have sinned MANY times, but I TRY to remember that.)...
...and - just maybe - whoever was playing it will be motivated by the improved looks of this (

yeah...I'm still going to remove the easy-to-remove single-layer dents:


Here are a couple of pics of "why it had to come off"...The formerly-F.U.B.A.R. small end:

Sadly, I couldn't find anything exactly this diameter (to use as a "mold"), but - when I was a little kid - my Mom (a commercial artist) taught me how to draw circles without using a compass.
