MPC fiber body tubes?
Hello All,
The body tubes in MPC's model rocket kits (particularly the later ones that had plastic nose cones and fin units) were referred to as "fiber body tubes," and I believe G. Harry Stine may have made this distinction as well in earlier editions of his "Handbook of Model Rocketry," between fiber and kraft paper body tubes. Those tubes do look different and have a different consistency (they're stiffer and harder) from Estes' and Centuri's body tubes. Was the "fiber" a different material (and if so, what was it?), or was "fiber" just a fancy name for a different type of paper? Many thanks in advance to anyone who can shed light on this!

Paper is a fiber. The ones we commonly see today are 100% virgin kraft. The CMR and MPC tubes has a partial recycled paper content and were a bit more rough or porous. These days you cannot buy virgin kraft tubes in CA at any price.

They were regular body tubes, but the outside was not a glassine wrap, at least not the glassine of Estes/Centuri tubes, and envelope windows of the time. I don't know precisely what it was, but it was a little more sandable, a little chalky (which made it white or off-white). I remember Space Age Industries had tubes like this that came with a slight texture that could be sanded smooth.

California is full of enviro-whacko FRIGGIN' IDIOTS.
Half of the crapola the politicians and bureaucrats pull there would get one LYNCHED here in Michigan. We have the most correct vehicle regs here; speed limits are treated as SUGGESTIONS, ZERO vehicle environmental testing/checks, ZERO non-commercial vehicle safety inspections. If it belches smoke like a 1920's coal-fired power plant, that's tuff fecal matter to enviro whaks. You can drive it down the road for as long as it lasts ! HUFF some fumes !

Hi GH - I'm tired of the California cliches. Have you ever spent any time in California, beyond a few days vacation in Los Angeles? Take a drive up the coast and stay longer than a week before you make judgments about people or lifestyles. Before you leave this post, please read all of it. I was very fortunate to be born and raised in Northern California, in the Monterey Bay. The weather was great! Mostly in the 70s, it only snowed once when I was five years old. No humidity on the coast. I never knew how great it was until I moved out of state. I've lived in many cities, all across the country, most for over a year. "Enviro-whacko FRIGGIN' IDIOTS?" There are idiots everywhere I've lived. The percentage of idiots is no bigger in California. The problem is, they put them on TV. That's all most people see representing the state. People are people everywhere. There are good and bad, smart and not so much. The percentage doesn't change by location. Gasoline? In the 1960s and 70s, the Los Angeles basin was covered in smog. Too many cars and too much exhaust. After all the emission regulations the sky is clear now, you can see the mountains and breathe the air. Rocketry regulations? In 1969 I couldn't get engines. Estes and Centuri would ship kits, parts and launchers but no engines. It was a hassle, but I did get a permit. I bought engines and flew rockets. Everywhere I've lived has had it's positives and negatives. I've lived in Florida for years. It's a hot swamp. But for now, it's home. Florida Traffic? Yes. Tourists who can't drive? Yes. Nut cases? Yes. People are people everywhere. If I had the choice, I hope to go back to California to live one day. Sure it's more expensive, but you are buying the whole package. The weather, the scenery, mountains and ocean. And yes, even the people. Earthquakes? You'd feel a few each year. Since the 1950s, newer buildings are built to flex. Usually it's the older buildings that fall. I'm a nut case. I play the banjo, bagpipes and the accordion. I also build and fly rockets so maybe I get a pass. I've never lived in Michigan, so until they broadcast a "Real Housewives Of Detroit", I couldn't possibly form an opinion about the people there. Sorry to sidetrack Blackshire's topic. Now back to the more interesting MPC body tube discussion. I liked the MPC tubes. Sand off the roughness and no seams to fill!
