OK, OK... let's just say that sometimes even I show a casual disregard for the fine print of the code. So, take this post as a confession (good for the soul), and not, heaven forbid, as an encouragement to violate the "Holy Writ" of the NEC.

I took a ammo box, formerly used for 40MM ammo:

I added some charcoal:

I set the pipe and cover like so:

The pipe used is schedule 80, 1" PVC. Before long, it drooped like this:

From this, wearing gloves, I made this nice, unscorched bend:

But, alas, all was not happy. I had some heat damage to the asphalt. While I was able to patch (using roofing cement), I took heed and added a pair of pieces of strut to the bottom, to let some air flow under the box.

John, you don't like heat blankets?

Or were you looking for a way to cook a burger and bend pipe at the same time?

Wouldn't it have been easier to just cut the stub-out shorter and use either back straps or the strut?

I like the idea of the portable BBQ in the ammo box...might keep the nosy back a few yards [Linked Image]

Oh, I could have cut the pipe a wee bit closer, etc., etc.,... but this is but one example of several bends I had made.

I have two things against heat blankets:
a) They cost much more than ammo boxes; and,
b) They require electricity to work...and, ironically enough, I was in the process of bringing power to this outbuilding.

John, I don't understand why you needed to make an offset, though.

Shock, it's not clear from the pic, but that trim at the corner would have interfered with the LB. With hindsight, I wish I'd placed the hole a wee bit better.

I also probably should have 'dry fit' the pipe before gluing it together!

I feel we should point out the NEC rule here.

Quote
352.24 Bends — How Made.
Bends shall be made so that the conduit will not be damaged and the internal diameter of the conduit will not be effectively reduced. Field bends shall be made only with bending equipment identified for the purpose. The radius of the curve to the centerline of such bends shall not be less than shown in Table 344.24, column “Other Bends.”


At least we should be aware of the code before we ignore it. [Linked Image]

I admit I have field bent RNC with equipment that was not 'identified for the purpose'.

John,
I have to admire your ingenuity(sp??). [Linked Image]
Not a bad solution really, if the heat can be reasonably controlled.

This is one thing I miss about all the Army surplus stuff drying up over here, it's really hard to get and way over-priced if you can get it.

Bob, you are, of course, absolutely right. Code requires the use of listed equipment. Someday I might even see that requirement complied with!

Mike, the coals seem to be pretty self-regulating. An even bed of coals = an even heat...and with the clearance you see, it seems to be 'just the right temp.' Best of all, when doing several bends, it is not necessary to "turn it off" between uses.
I think that the hot gasses from the coals help them to heat the pipe more evenly than, say, a radiant heater.

Otherwise, Mike, for some silly reason we seem to have no shortage of empty ammo boxes these days. It seems almost as if the Army is emptying them on purpose.... [Linked Image]

I think you have the start of a nice little portable 'smoker' add another Ammo box, change your fuel to wood....
