It's much easier to use thread-forming taps in aluminum than thread cutting, and the threads are far stronger. Blind holes are not as large a problem. Lubricate with soft wax, not Tap-Magic. Also, why 4-40 in a 0.25" thick wall? A larger screw will actually be easier and again, stronger. .<https://www.mcmaster.com/#thread-forming-taps/=17p2qoh> .<https://www.mcmaster.com/#lubricant-stick-wax/=17p2rpl> Joe Gwinn _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
