I knew my build was going to well. Ive just finished the canopy with no issues and was working on drilling out the nose leg on my 7A for a taper pin.
I've gone too deep with the reamer (broke the first one and in my excitement to get the hole finished with the new reamer i didn't check the depth often enough. I had the first reamer marked with tape to warn me but in my haste didn't bother with the new reamer. Like others, reaming the hole was a pig and than it suddenly started cutting and i got carried away in my excitement at making chips.
Its about 1/8 inch too deep but looks like an expensive 1/8 inch. I got that horrible sickening feeling when you know you've screwed up big time.
Ive got a quote from a manufacturer of taper pins of $900 for one pin (ouch) and am awaiting a local machine shop to quote. The Cadmium plating alone has a minimum charge of $160 (UK prices). Im looking at Stainless Steel as an option.
Im wondering what other options are there? At this rate a new engine mount and nose gear will be cheaper. Can i get a new nose leg and weld the holes in the engine mount and re-ream the mount? Can i just enlarge the hole to take an AN6 bolt?
Any thoughts welcome and hopefully my mistake can help others.
Main thing is no one got hurt.
cheers
