Thanks! That's what I needed to give me the solution.

#include <boost/bind.hpp>

namespace
{

class functions
{
public:
        int func( int ) const;
        void test() const;

protected:
        int func( int, int ) const;
};

void functions::test() const
{
        int (functions::* func_1)( int, int ) const 
                = &functions::func;
        
        boost::bind( func_1, *this, 1, _1 );
}

}

This is a much more like what I was battling.

(Thanks for reminding me about the list archives as well.)
