bobble heads

[Kent Swafford]

Wim,

The hammer tails are likely not shaped correctly. Decrease the radius 
of the tails slightly, or in other words, round the tails a little 
more. Not much material will likely need to be removed; just get out a 
paddle with some coarse 60 grit or so paper, and you'll be checking in 
no time.
