Is it possible to build a bike frame out of threaded plumbing pipe?
I
know it would be super heavy but could it be done?


Most things mechanical can be done if you throw enough time and money
at
it. This sounds more like an interesting project rather than a serious
endeavor.

Plumbing pipe isn't a very accurate description since at one time or
another lead, brass, copper, iron, cast iron, plastic, wood, cement
and
even fired clay have been used for some type of "plumbing pipe".

If you are referring to plumbing pipe sold in the US that comes in
various
lengths with both ends threaded, it's made of low quality steel or
even
low carbon iron as in iron pipe, not cast iron pipe. Either of these
materials will generally have less than half of the strength of most
steel
tubing used in bicycles.


Hmmmm.....how about a "spaceframe" made of smallish diameter copper
tubing brazed together (think "Bird Cage Maserati")? The CTTL ("Copper
Top Tube, Lugless")!


Be sure to use lots of "pipe dope"...... ;-)

Almost hate to comment on it, but in the oil field pipe dope is used so
that you can later break threaded joint apart. That might not be such a
good thing here.

When I was working in East Texas (back in nineteen and sixty-four) 'dope' was used to seal the weld joints on pipelines.  Not Pipe Joint Compound - that's used on threads.  This stuff was the most God-awful, obnoxious stuff I have seen.  Most guys on the crew would break out in hives just from the fumes.  It was usually brushed on with a six inch brush like house painters used, but we had one little guy in his fifties who would use cotton gloves to slop it on.  Stuff didn't /appear/ to bother him.  I've often wondered how long he lived.
