Self-centering eyes

Question: I was wondering if self-centering eyes could be added to my Lovik Knee Pal, "Gary Guitar", and if so, what would be the cost?

From Mr. D: Yes, I have added the self-centering mechanics to a number of Knee Pals, but the degree of success depends on how freely the eyes move on the individual figure. The cost generally runs $40-50 plus return shipping, and the job takes about 5 days in my shop. I really need to see the head to give you a more specific answer. (Our son, Kevin, also does this work but I know he's booked through the end of 2011.)
