The questions is what do you think is the most reliable way to free up sluggish hammers without replacing center pins or parts?  Should I use silicone and naptha, alcohol and methanol or install a Dammp-Chaser heater bar with a humidistat?</FONT></DIV> <DIV><FONT size=2></FONT> </DIV> <DIV><FONT size=2>Thanks,</FONT></DIV> <DIV><FONT size=2>Arthur</FONT></DIV> <DIV><FONT size=2></FONT> </DIV></BLOCKQUOTE></BODY></HTML>
