Mitering Pipe

[Lanse]

Hey yall!!

So, Im back to working on the BBQ again, and last time I was at the steel yard, I picked up several feet of 5 or 6 inch pipe, to use as a couple smokestacks for the thing.

Now all I have to do is cut it up. Its too big for the bandsaw and chopsaw that I have, so I guess I'll have to get creative and use the plasma somehow.

I want to cut four 22.5 degree miters to form a 90 degree smokestack, going from the side of the BBQ out, and upwards.

I don't know where to start lol. Somewhere online there is a template printing thing, where you just enter the size of the pipe and it gives you something you lat over the pipe and trace. I can't seem to find that right now...

But surely theres a "legit" way to go about this, and I might as well start to learn it now rather than later.

Any and all help is greatly appreciated. Hope everyone's week is going well so far.

google search pipefitter chart. You can buy these that are made out of gasket paper to lay on the pipe and get the angle. How heavy is this thing?

One of these days you're going have to teach me how to post a link on this site.

Until then copy & paste this.

I could try doing a layout on SolidWorks and giving you a flat pattern if I knew the diameter and thickness of the pipe you want to cut, and the angle at which you'll be welding it to your cover.
I'll need the dimensions of the piece which you'll be attaching it to, though.
D you have sketches of the finished product, or is all this being done from the back of a hot dog wrapper, LOL?

When I do that kinda stuff I get real technical by using alla my math skills and them some.

I would eye it up real close and cut to what I thought should fit. Then I would put it in place and anchor it somehow, get out my drawing compass and set it to the widest gap and draw a line all the way around and then cut on the line.

Always works for me.

If thats to complicated I jus don't know what ta tell ya.

If you can get The Pipe Fitters Blue Book by W.V. Graves. It has all the necessary measurements for those cuts.

Until then here is the page from the book with the measurements that you will need for the 22.5 deg cuts.

Sorry pic did not upload first time.

Yep, when working with pipe / round tube these books are a big help.

Thanks Puddles!! Thats the exact site. Maybe
you're the original person who I found that link
from, idk...

Either way, posting a link just takes a few
seconds, atleast in classic view. I dont know how
it works in the modern view, on the "other site"
the link just pops up.

But here in classic view, all you do is:
1)Highlight the link of a website and right click
it, then hit "copy"

2) Come here to the posting page thing, and theres
a box right next to "Optional Link URL". Right
click somewher inside the box, and click "paste"

3) Put a creative title in the "Link Title" box.
"Poke Here" or similar is pretty popular...

Hope this helps. Thanks for the link

Thanks Lance! Yeah, I use the modern view. Closer to all the other sites. That is exactly how I do it everywhere else but here. This site is such a PITA! Maybe I should go back to the classic view. :roll:

There is actually an easier way (IMO) If you look up top there is a [u:d8dcb0e986]URL[/u:d8dcb0e986] box. Paste your link, highlight, and then click the [u:d8dcb0e986]URL[/u:d8dcb0e986] button again. This will put fancy HTML stuff around your link. No changing the name to a funny name though.

Cut your hole the same size as outside of pipe, drop it in and weld. If it protrudes a bit into top of tank, inside, no big deal!

I think if you make a 45 degree cut them rotate one piece 180 degrees you will have a 90 elbow

Before you go to all the trouble of making these cuts I think you should rethink your pipe size. 5" or 6" smoke stack is way too large for any normal size pit. Besides, the whole idea is to limit the draw not make it pull harder. If you put a moveable flapper on the top all you've done is choke a really large pipe. A pit of about 55 gal size will draw and smoke much better with no more than a 3" stack. Even this size pipe you need a throttle.
