<div id="_htmlarea_default_style_" style="font:10pt arial,helvetica,sans-serif"> Posted for billhogarty &lt;billhogarty@hughes.net&gt;:<br><br> Am I the only one having a problem with the spring that actuates the <br> locking pin on the retractable step.  I have had to replace it once  and now <br>it has collapsed again.<br> <br> Any one else have this problem?  Is there a replacement spring maybe using <br>stronger material?<br> <br> Anyone knowledgeable about springs?<br> <br> Thanks, Bill Hogarty<br><br>[Some general rules about coil springs, if the size of spring wire used remains the same, if you halve the coil diameter you double the spring force and 2) if you halve the number of coils per inch you also double the spring force.&nbsp; If you keep the number of coils per inch and the coil diameter the same but double the OD of the spring wire you quadruple the spring force.&nbsp; &lt;Marv&gt;
