Another technician here showed me exactly the opposite just recently. Removing the pins with a brace (or even a T-stringing hammer) got the pins so hot you couldn't hold them. The electric drill didn't give them time to get hot. They were warm, but you could hold them.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Jeff</DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR><BR><DIV> <SPAN class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; text-align: auto; -khtml-text-decorations-in-effect: none; text-indent: 0px; -apple-text-size-adjust: auto; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px; "><DIV>Jeff Tanner, RPT</DIV><DIV>University of South Carolina</DIV><DIV><BR class="khtml-block-placeholder"></DIV><BR class="Apple-interchange-newline"></SPAN> </DIV><BR></BODY></HTML>
