I had a couple with the problem. The recommended procedure was over a period of days to flow lighter fluid, which is very flammable, down the gap between the concentric shafts and turn the shaft back and forth while holding the plates in place. I forget the detail, but if this procedure did not free things up, the shaft was to be heated with a very large old style soldering iron, which would cause shellac like gunk to flow out of the concentric shafts. Of course you don’t do this until you are sure all lighter fluid has evaporated. There is probably someone on this or other Heath groups who can shed more light on this. I hope so as I have forgotten the details. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext'>Bob W2WG <o:p></o:p></span></p><p class=MsoNormal><a name="_MailEndCompose"><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext'><o:p> </o:p></span></a></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif;color:windowtext'> Heath [mailto:heath-bounces@puck.nether.net] <b>On Behalf Of </b>Guy Giacopuzzi<br><b>Sent:</b> Monday, April 18, 2016 4:16 PM<br><b>To:</b> heath@puck.nether.net<br><b>Subject:</b> Re: [Heath] AR-3 - another question<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>I'll check my "re-kitted" AR-3 this weekend when I go to Mammoth...<br>Guy<br><img width=975 height=100 style='width:10.1562in;height:1.0416in' id="_x0000_i1025" src="cid:image001.jpg@01D1999B.0F31FD50"><o:p></o:p></p><div><p class=MsoNormal>On 4/18/2016 9:36 AM, Kenneth G.
