Would be interesting to see it crawling round a 4 foot pipe.

I prefer not to use pipe cutters - I used to, but it crushes the end of the pipe in and takes a lot of work to clean up properly. You get much better results with less effort by using a hacksaw neatly. Getting a straight cut isn't hard - slide a slip coupling to the appropriate place on the pipe, use the edge of it to mark a line the whole way around with sharpie, cut to that line, clean off the sharpie.

Obviously though, a hacksaw isn't much good when you've pipes multiple feet in diameter. :tongue3:

Really you don't have a hacksaw 6 feet long?I thought everybody did :D

You could make one yourself with a mini torch and just set the pipe on rollers.It wouldn't be practical but why not!

My brother-in-law was a boiler-maker at Voith (sp) in York Pa. They make hydro-turbines for dams. He got to use all kinds of specialty tools like this.

D_Hall: I'm not quite sure why you decided to post this thread... Your writing tone and your apparent need for a machine like this are, well, interesting. I don't know much about you at all but I've been reading your recent posts and they make me wonder...

So what is it that you do? What would you be interested in hiring any of us for?

From his website..."Who are you? What's your day job? Why do you know all this wierd stuff?

My name is David Hall. I'm a Mechanical Engineer employed at the Naval Air Warfare Center, Weapons Division, Ordnance Test & Evaluation Branch. I started my career writing flight simulations. These days I test rockets, and guns for the military. Combine those two assignments and voila."


Bases on his comments, he has/gets to play with spook toys for the US government.

Edit: Or he can beat me to the punch and tell you himself.... :wink:

Experimental weapons, eh? In that case, forgive me if I came across as rude.

That sounds like one hell of a job. What kinds of weapons are we talking about?

Experimental ones. :tongue5:

Sorry, couldn't resist. :D

He has made minor mentions of some nuttiness he's been involved with in passing, but to be honest, a lot of what he does will no doubt be classified - as you might expect of experimental weapons...

Not spook toys. Spooky toys! They are, after all, experimental. Some of them don't work right. Eerieeeee feeling when things don't work as advertised. :shock:
