Thwing" Subject: Re: Zenith601-List: Re: I don't understand... do not archive I'm not a 601 builder, but I drill a lot of holes. I measured several AN3 bolts furnished by ZA last night. Smallest was .187 and the largest was .1885. One way to help visualize slop is instead of diameter over, picture how much over per side. For example, if your hole is .003 oversize, that's .015 of space on each side of the bolt. And you already know this but......don't just believe the the size drill you buy will bore the stated size. Many are poorly ground with uncentered points. And your technique makes a difference. Measure test holes, not the bits. A guy came into my plant and asked "how can I make this bit drill oversize?" That's easy, let me sharpen it. I am adding metric diameters to the list below. They are available for about the same money, Regards, Randy, Las Vegas From: Afterfxllc@aol.com 4.75 mm = .187 3/16 = .1875 #12 = .1890 4.8 mm = .189 #11 = .1910 4.9 mm = .1929 #10 = .1935 #9 = .196 5 mm = .1969 Really splitting hairs here. ________________________________ Message 2 _____________________________________ Time: 08:36:03 AM PST US From: "George Race" Subject: Zenith601-List: Chat Live Chat Room every Monday evening around 8:00 EDT www.mykitairplane.com Click on the Chat Room link at the top of the page.
