One thing to mention is that you cannot >drill through lead without using some cooling and lubricating agent like >kerosene or cutting oil. >Dan ++++++++++++++++++++++++++++++++++++++++++++++++++++++
I drilled my lead weights with no problems and no cooling or lub agents. The bit tends to fill up rather quickly with the soft material and you need to keep pulling the bit out of the hole to empty the lead but other than that , no problems. Are you using a GOOD sharp bit? I just spent three days disassembling an ultralight type aircraft that a friend crashed last summer and put himself in the hospital for about five months and is now in a wheelchair. My next project is to build a paint booth, finish priming the KR and get it painted. It seems the time till Red Oak is flying by! I could get 15 hours of free flying time in a kitFox if I had the time. LIFE IS TOO SHORT! Larry Flesner
