Retrofitting New Window Screens On Restored 'Retro' RV Camper


RV camping is currently enjoying a resurgence in America. Among the thousands of people taking to America's highways in trailers and motor homes in recent times, there is a growing segment of folks who are restoring older units. This is often done for nostalgic reasons and/or to beat the high cost of a new RV. Recently, I got my hands on an online bargain. The camper shown in the photo dates to the early 1970s and was near completely restored by the previous owner. He sold it to me because he has a child and large dog, and now needs a larger RV. There was one issue with this camper: The restoration job did NOT include screens on the windows. And anyone who has been camping knows how troublesome mosquitoes and flies can be. Also, anyone who has camped in an RV knows that if one is camping in an area where power for the air conditioner is not available, it quickly becomes a "sweat box" unless one can open windows for cross ventilation. So window screens are a MUST.

This RV presented a unique problem due to the design and construction of its windows. Most RVs I have owned or traveled in have a crank that operates the window. On some, this crank is intelligently positioned into the window frame; in others, there is a small, discrete hole in the screen through which the shaft for the window crank protrudes. In the case of this particular camper, the latches which hold the window glass closed are located directly behind where a window screen would be. Thus, it would be impossible to open and close the window when using a conventional window screen. The next photos show this problem:


















I came up with my own novel engineering solution. I'm not saying this is necessarily the best or only solution, but it is what I came up with and it works. My approach was to have an immovable section of screen in the middle of the window, between the bottom latches, with movable screens resembling shutters on either side to allow access to the window latches. The next photo shows my completed installation:
When I first installed this, I realized that despite considerable care in minimizing the gap between the movable and fixed screens, that gap was still wide enough to potentially allow mosquitoes and other "no-seeum"type insects to get in. So I used an outdoor-rated duct tape to seal this opening. This can be seen in the next three photos:



















To some folks, the tape scheme might seem a bit "hillbilly", but it was inexpensive; I had it lying around, and it is certainly easy enough to fix if/when needed. And finally, the next two pictures show how it operates:



I hope this helps someone restoring an older RV or at least gives them ideas for a workaround.

This Is The Stuff Nightmares Are Made Of


An article came out today in the Idaho Statesman that enumerates various incidents where the US government has LOST weapons grade nuclear materials. According to the article, "since the cold war ... 6 TONS of bomb materials have gone MUF", meaning "material unaccounted for". The article goes on to say that some of this "may be stuck in pipes at processing facilities, etc." so just because it is unaccounted for does NOT necessarily mean that 6 tons were stolen.

That said, the article starts off mentioning some samples of material that WERE recently stolen from a rented SUV that was being used by "two security experts from the Department of Energy's Idaho National Laboratory." While these samples were NOT sufficient quantity to make a nuclear weapon, it bespeaks of a lack of security in the handling of such materials.

But knowing that there are 6 TONS of nuclear material - much of it weapons grade - that are MISSING or unaccounted for, does NOT leave one feeling "warm and fuzzy". This is theoretically enough to "make hundreds of nuclear explosives', according to the article. Also, according to the article, an amount of plutonium the size of a grapefruit is sufficient to produce a bomb.

Think terrorist bomb, 'dirty bomb', possible EMP weapon, etc. SCARY!!!
