So, you've torn down your turbo, what ever it may be, and you have a busted fin. No need to junk it, its fairly easy to repair. Chances are, if your re-building your own turbo, your competent enough to fix your compressor wheel.
C/W = Compressor wheel.
Oops
So here we are, damage to fin, heres how to fix it.
First weld in where your fin once was.
Should look similar to this.
Next (if you have access) Chuck up and true your C/w
If your a machinist you'll hear when your cut enough if not get a 0 on a different fin and remove a little at a time. Use a high speed.
Here's a good idea of what your shooting for.
Its far from perfect, but stick with it
Almost....
Air grinder, time to use it. Here it takes a little bit of a steady hand and some patience. stick with it and try to keep the contour of your C/W.
Polish it up.
Blend and debur, you end up with this.
Notice contour and tip height.
Overall fin
Fin repaired.
Now if you want to go the extra mile.
Glass bead Blast the whole c/w.
Which fin busted?
C/W = Compressor wheel.

. leave it to DSM'ers to pick up the flaws. The same process can be done on the turbine. I happend to drop to the assembly on the way to balance, thought I would do a write up. On a side note, two other fins were busted during the tear down. however more time was spent blasting the C/W
