Bolt arrival and a little surprise

If you read last post, you know I just ordered the keel bolt from McMaster-Carr.  Which is an autoparts supply place mostly, but they have all kinds of stuff.  I ordered on Friday, July 3 and got it Tuesday so that was great. The website doesn’t tell you how much shipping will be when you order, so I didn’t like that part. It was only five dollars, but this is a small order. I’m not sure I would want to order a big shipment and have an unknown fee attached.

I ordered a drill to drill out the old threads, a tap to make new, bigger threads, and a new bolt.

The new bolt is only 3/32 bigger than the previous one, so not much as you can see in this picture of the ends.  The new is on the right. Doesn’t look that much bigger does it?

Take a look at it from this perspective:

wow! That was a big surprise when I opened the box. So the new bolt is just a bit bigger than the old one! No wonder it is rated for 5000 pounds!  I may have trouble fitting it in the old spot on the keel. I guess it’s a good thing the keel has already been cut down some in that area.

I also got the drill bit and the tap delivered at the same time.

Looks like it’s time for tapping party. Not sure when I will be able to get to it though 😦

Keel eye bolt materials purchased and on the way

In my previous post describing my eye bolt probable solution, I was unable to find the exact bolt that I had calculated using the drill and tap chart. I went back to the website and this time was able to go right to the sizes I wanted, I’m not sure what was different but I’m happy they worked out. Here’s the drill and tap chart as found on http://www.shender4.com/. Note that the items highlighted in a pinkish color are the sizes provided and recommended by the well-known Catalina parts dealer. You will notice that the drill size is under the aluminum brass and plastics. It seems to me we should be using the drill bit size for iron so that’s what I’m going to do on the new eyebolt. The colors in yellow indicate the eyebolt size and thread and the drill bit size.

Just to remind you, the standard bolt they use looks like this, so there will be some differences in the way I hook it to the winch cable.

Smithsonian Air and Space Museum – Dulles Airport

On Father’s day weekend my son surprised me with a visit, all the way from Orlando.  Quite a shock to come in from Laser racing at WRSC and see him and his fiance sitting at the dining table with Mrs. CapnRehab!

So I put aside all my work plans and just had fun.  One of the places we went was the Steven F. Udvar-Hazy Center in Chantilly, VA.

It is an amazing place full of all the planes the Smithsonian Museum downtown in Washington DC doesn’t have room for. It’s also the place where they restore planes, and you can see the work areas from a big observation deck. If you come to Washington DC for vacation or to visit, I recommend that you try to fit this place into your schedule and give it a full day to really give it justice.

They have tours that start frequently and a very knowledgeable guide will take you around and talk about the different planes. Our guide was so knowledgeable because they have to take continuing education classes and also get tested every year. He talked about approximately 60 planes but there are way way more planes there than that.  He was very informative and made the tour very interesting. Much more interesting that had we just walked around and looked at planes.

Some really famous planes are there too. Perhaps the most famous plane there (although there was some steep competition) was the the “Enola Gay”. This is the actual plane that dropped the atomic bomb on Hiroshima to help end World War II. The outside has been meticulously restored to its original condition.

I just read “Flags of Our Fathers” about the invasion of Iwo Jima and how difficult it was. 6,821 US and 18,844 Japanese soldiers died on one little island a little more than 3 miles wide.  It was the final island to be taken before the planned invasion of Japan.  If we had invaded Japan those numbers would have been minor compared to the carnage that would follow. I also read “Unbroken” which you saw a review of here a little while back, also about World War II. Having that background made seeing this plane a little more meaningful for me.

The first plane you see as you walk in the door is the SR 71 blackbird spy plane. The tour guide told a story about how once the plane is flying it heats and expands by 9 inches so it was designed to be loose when it’s on the ground, and that means it actually leaks fuel. So they would only fill it enough to get it off the ground and then it would have to go to an air tanker right away to get a fill up.

Another great plane from my childhood is the worlds first super sonic airliner – the Concorde. It could go from London to New York in just a few hours -, not anymore.

Last but certainly not least is the space shuttle discovery. This is an actual spaceship that has gone into space and returned. The whole hanger there is dedicated to space exploration and I saw several projects that I’ve worked on through NASA. Pretty amazing!

Oh, and don’t forget the selfie!

Okay, it’s not really a selfie. MrsCapnRehab took it. 🙂
