Firewall deburring

When I got home today, there was a package at the front door. Merry Christmas! My brother had sent me a tungsten bucking bar! I had a steel one exactly the same size, but compared to the tungsten one, the steel feels like styrofoam, it's so light. This was a really great gift idea, because I'll use it all the time, but it's one of those luxury items that I wouldn't have bought for myself. Thanks, Chris!

Fortunately Kerin was working late tonight. I didn't want Kerin to feel left out, so I quickly unpacked it and stored it in the toolbox before she got home. The shipping box went in with the other shop trash. I won't tell if you don't tell. :-)

Well after that, I went to read some posts on Van's Airforce. After a long day at work, sitting down was not the right thing to do because that turned into a three hour nap. Like I say, "I never met a nap I didn't like." :-) Anyway, around 10:30PM I went looking for my longeron yoke. I found it on the bench by our front door. What it was doing there I have no idea, but I got that one hole flattened out in a jiffy.

After that, I deburred all the holes in the firewall that I had match drilled on Sunday. One side of the firewall just needed a turn or two with the deburring bit. The other side had a heavier burr at each hole, so I polished each hole with the ScotchBrite wheel in my die grinder, then deburred with the deburring bit. I dipped the bit into Boelube every fourth or fifth hole to prevent dulling the bit.
