I love the idea of a 3/4" (nominal) shim in a milling operation.

Sir, I beg to differ! NASA would have found the most expensive possible solution, then given it to a committee to add complexity and expense, then spent even more on having it certified

You're making me blush Tom.

I can verify that (at least back in '69). I had to wait 3 1/2 hours for a 1-page document specifying a mil 100D symbol rivet notation. It was for a sheet aluminum component for a mock up for a fuel cell used to determine how the space capsule would react in flight. The results turned out to be horribly crafted and unsightly. The solution that I proposed was to thermoform the item. The engineer insisted that that couldn't be done. (not true !). When I suggested fiberglass it was instantly accepted. Go figure....

This morning I started to set up the next operation on the crank case of the 5 cylinder radial
http://www.hobby-machinist.com/threads/five-cylinder-radial-with-ohc.34815/
and I noticed that the Y feed was loose when pushing the table towards the rear.
On investiation I found that the Gibb adjustment screw was not holding the gibb and allowing the part to slide out away from the table.??????
After a few cusses I made on a small plate held by the original location hole and a small grub screw for adjustment.
It works.
I know it's not the most elegant design But at the age of 76 I don't even buy green bananas.

So, yesterday evening the GF and I did a teeny tiny bit of shop work. We made these:
A length of PVC pipe, about 40' of contractor's twine, a dropper knot, and a 2 oz weight.
Why?
To get more of these:
My GF and I found a beautiful little out-of-the-way-and-off-the-beaten-path place to catch blue crab. About 15 minutes from the house. For those that have never gone crabbin' for blues, let me explain.
We use chicken drumsticks (cheapest we can find, usually about $5 for a dozen) as bait. The chicken gets tied or wired to the dropper loop. The PVC pipe is used to anchor the line to the pier or structure or convenient branch(and to wind it onto for storage), and you simply toss the chicken out into the water. When you see the line 'going for a walk', you gently pull it in until the crab is right by you, just under the surface. Then you scoop it up in a net, and dump it into a bucket. Toss the chicken leg back out, and repeat. The 2 oz weight keeps the tide or current from drifting your lines too badly. A blue crab will keep a death grip on that chicken right up to the point you scoop it into the net. It's not unusual to pull it up and have two crabs hanging on to the chicken with a third (always smaller, they're bullies) swimming behind them.
And those b@$tards are *INSANELY* aggressive. They don't just throw their claws up in a defensive posture, they'll lunge and *try* to get you. If you drop something into a bucket of live blue crabs, you can pretty much write it off until the bucket is empty. The little ones have razor sharp tips on their claws, the bigger ones are just stoopidly powerful, and all of them are lightning fast. Got nipped by a cute little 3" wide one a few weeks ago, right on the fingertip. And bled like a stuck pig for 10 minutes. One of the big ones would ruin your day completely.
And how do they taste? Like heaven. Sweet, buttery, melt-in-your-mouth goodness. Can't wait to get another batch of 'em, 'cause the GF wants to put some on the smoker, and I wanna grill some up. Got to love a woman who loves to fish and crab, and is a helluva good cook as well!

Decided to make some T-nuts for my big mill today. Thought about ordering some then decided I didn't want to wait for shipping, would rather do some cutting.
I did do some crude torch/wd40 blueing but I put them to use claiming a job down already so no pictures.

In NASA'a defense, they were designing and building a rocket that put men into space. If I was riding the "tip of the spear" with a controlled bomb going off under me I would hope they did a good job and double-triple checked all of the work. I know when I was an engineer in my previous life, if someone's life depended on my work I made sure I wasn't going to be the cause of any problem.
