There's an old machinist trick for adjusting the fit of a pin in a hole from loose to tight that you can use. First, use a screw whose head will be recessed below the bottom face of the case when screwed fully in, because otherwise the head will interfere with the cover as it is slid back into place. A #4 socket head screw is slightly too big for the hole in the calculator bottom half, so a #2 or #0 flat head or round head screw should work. A tapered sheet metal screw would work best, but a regular machine screw can also do the job. With either screw type, you may need to widen out the post hole a bit using the proper tap drill size.

Then thread the screw all the way into the post hole with the case halves together. If the halves are a tight fit, you're done, as the outward pressure of the screw on the post diameter is enough to tighten the post in the hole. If not, remove the screw, separate the case, then split the post down through the middle of the hole using a fine saw or Xacto blade. You'll probably only need to split the post no more than half the way down.

Assemble the case halves and thread the screws back in. As they go in, they will push the two post halves out and against the hole in the case bottom. Bingo, a nice tight fit! Should keep the case from popping apart if you drop it.

Quote: I entered college in 1972 at almost exactly the same time the HP-35 was released, and it was the hot status symbol for a few rich kids (not me) whose parents could afford the price (about $2000 in today's dollars).

Hey! I was one of those "rich kids" but it wasn't my parents who bought me my HP Scientific Calculator! (1302A29315) Nosiree, it was six months as a McDonalds fry cook and Howard Johnsons night clerk after class, saving every single penny - Every! Single! Penny! - not withheld by the government to get enough for it. You're right about the "hot" part though - in the spring of '73, even the prof's would ask if they could try the calculator Wink

Sidenote: if you really want to see the weird side of humanity, try working as a night clerk at a motel for a few months!
