Screwdrivers




The Thrifty Rocketeer continues...

 Every tool kit has them, and you'd be hard pressed to assemble most anything with at least one.

We're talking about the humble screwdriver.

But it seems to me that I read somewhere that it was developed because it was easier and faster for repairmen or assembly workers to align the Philips head screw driver than a "regular" one.  But I don't recall where I heard that.


These days, there's a wealth of different heads on screws, each requiring a different type of screw driver head.   The first I ran into was a square-hole head that was in Japanese electronics.  To open up the molded plastic case (which you weren't suppose to do), you needed this unique bit or screwdriver to remove the screws.

 And soon after, we ran across the style that had beveled heads, meaning you can turn the straight blade head IN, but there is no flat surface to back the screw out.  This is a safety head screw and it was used around high power supplies and tamper-resistance units.

 It seems like it was the mid-70s before I saw a star-drive screw.  This is similar to the square-drive screw, except a six-pointed star indentation in the head will only accept that asterisk shaped tool head.  It wasn't too long before we discovered you could force some of these star screws to back off with the appropriate torque on a Phillips head screwdriver.  Or, if your regular screwdriver head was small enough, you could insert it into the star depression and get a bite on the screw.

But by the 1980s, there seemed to be an explosion in type and styles of screw heads, each with it's own prescribed head or bit.  My wife picked up a pack of bits and a handle for interchangeable bits to be use to service a computer.  She guarded it zealously and wouldn't let me have it until after we were married.

Nowadays, I'm finding square drive bits packaged inside packages of deck screws so that you can power drill the screw into 2x4"s and other wood.

And it seems like every time you buy any cheap molded plastic case tool set, there's at least one multi-purpose handle to use with the row upon row of custom screw head drives. Squares, stars, straight, Phillips #2, Phillips #4, Phillips #6 or whatever you may need.

Now, the more complex your rocket kit, particularly if it involves an electronics bay or a set screw to arm or activate the circuits, the more you'll need a toolkit like this. (Low power rockets have no need for these tools...yet...)

But if you're trying to find something for that rocketeer who has everything, you might look for a set of multiple bit heads with a socket handle.  Santa probably has just about everything needed in stock.

The End of the Line

 The Thrifty Rocketeer blog continues... Well, for years, the state of the model rocket industry relied upon plans and patterns that were photocopied or printed out, and then applied to standard sheets of balsa to be cut out. Eventually, the various parts for various sized rockets were packaged in groups or blister packs, and sold at hobby shops across the nation.  The emphasis was on home brew or building a rocket to specifications and plans. Eventually, entire kits were pre-packaged, with all the parts that one would need.  And then, laser cut shapes, fins or parts were already pre-cut, doing away with the need for most of the patterns and tracing. So what happened to all those bags and bister packs of parts of rockets?  That is, a baggie of various nose cones... or connectors... or transitions or more ?   Many of  those packages remain at your local mom and pop hobby store, just waiting for someone to come in and buy some of their pegboard stock....

sleeping with the enemy

 The Thrifty Rocketeer blog continues... First thing I did when they put in a Hobby Lobby in my smaller metropolitan town, 40 miles away, was to grab an application to work there.  Now I know what you're thinking... "How could you?  Who would want to work for that conservative corporation?".. as my daughter would say.  And you'd be partially right. I saved the application and took note of the mailing address. Within the first month or so, most of the initial buying frenzy was over, having sold out of some things, but not everything.   But it seemed nothing new was getting restocked. So, I got on my word processor and wrote a letter to the store management, THANKING them for bringing the store to our isolated metro area. I pointed out that many of the items had sold through completely, and how much we had appreciated their stocking rockets. Then I also encouraged them to restock and consider expanding the display, pointing to the fact that as rocketeers grow...

Death of a Hobby

 The Thrifty Rocketeer blog continues... No, this is not a column about how Model Rocketry is a dying hobby.  It's actually about another sister hobby that sometimes overlaps into Rocketry. I'm talking about Amateur Radio. Just this last weekend, our local Ham Radio club held a "swap meet" which is commonly called a Hamfest.  These gatherings to buy and sell used equipment, parts and visit old friends typically happen just once a year and in the absence of the late Radio Shack, is one of the only places to find parts and electronic elements. There is also testing held to advance to higher licenses. The admission varies depending on the club, their overhead, expense of renting the hall or venue, and the number of tables that they can sell to area vendors who will drive across state with their wares to set up for the half day show. It's not uncommon for amateur radio operators to drive across state to attend, pay admission and get a single entry into the door prize ...
