Can I safely have the stock two piece drive shaft in my '71 F-100 longbed
converted to a single shaft?

Safe? Probably, when it breaks I doubt that it would injure anyone.

Why would you want to do this?

Before you do that, you should do a bit of research. One of
the factors that determines the maximum RPM of a drive shaft
is the length. That is because the longer the shaft is, the
more critical balance becomes and the more likely it is that
the shaft will "whip" as the RPM increases. This also
influences the torque rating of the shaft and reduces the
critical RPM of the shaft. You can find one calculator for
critical speed here:

The two section design also safely allows for greater
overall driveline or U joint angles which help reduce joint
failure.

You can probably do this if you increase the driveshaft diameter to about 6
inches with 1/4-inch wall oil pipe.

Yeah Ernie, you must be an automotive engineer or something, more like a
sand lot mechanic. Next thing you will be telling us is to use 4"
diameter pipe and 1/2" wall thickness. And, don't forget to fill that
pipe up with lead or concrete. Why would we expect that you know any
more about driveshafts than you do about quoting, when posting to
newsgroups?

My local drive shaft place won't make one over 77". I'm with everyone else,
why would you want to change it?

How so???

Ernie Sparks

As a matter of fact a mechanical engineer, made a lot of money over the
years designing many different types of machines and equipment ranging from
mining to EPS fabrication, as well as RVs. The laws of physics apply to
everyone and everything, given the same situation. Twisting a long shaft
produces interesting results, especially when a lot of torque is applied at
one end and considerable resistance at the other. It's pinheads like
yourself who don't understand what takes place that gets people killed and
maimed when they refuse to seek sound advice. In driveshafts larger
diameters with hollow interiors are much more sound than solid shafts. I'd
go into the physics of why but I'm sure it would sail far above your
carrot-top hairdo.

Tyrone

Speaking of "Pinheads" Ernie, who are you replying to? How would anyone
know? Have you ever heard of quoting?
