I changed out the T-handle on my emergency brake shaft on my 65 A100. The new plastic T-handle also uses a rolling pin, however, I have not had success drilling out the old rolling pin. I even tried to drill a new hole through the emergency shaft and nothing seems to phase the steel shaft. I have used cobalt drills, high-strength steel bits, and titanium coated bits and nothing. I dipped each bit in cutting oil and that did not help either. Any ideas on what drill bits to use that will cut through this steel shaft? If drilling won't work can anyone recommend a really strong glue or epoxy that will glue the new handle to the shaft? Thanks,any suggestions will be appreciated.
