3D printed pipe miter pattern

[Stu]

I making an odd ball 3 way pipe miter and after going down the rabbit hole grinding and fitting, I made a 3D printed pattern. Stu

Nice job! Handy little things, aren't they?

Great idea, great implementation!

Can be done with normal straight cuts

The big engineering company where I grew up had a marine division. They did both rectangular and triangular cross section tubular booms for off-loading bulk material handling vessels such as grain, coal, etcetera. This was all pre computer, and the cut-templates were all designed by hand and then cut from cardboard manually. I never worked in the marine division, but the guys who did were very, very smart. ----Brian

There are books on sheet metal pattern drafting that show how it is done manually.

That's the ticket, Thanks!. Also I want that saw! Stu

I am a tin knocker, I gave my pattern book (by Daugherty & Powell, great book by the way, it got me through my apprenticeship) to a new apprentice when I retired. It just occurred to me that I could have taken measurements from the cad and made a paper pattern from that. Oh well it's done now, have to remember that for the future. Stu

That 3D print is a good solution. Whatever floats your boat.

For those of us who don't have a 3D printer this software works very well. I've used it quite a few times and
the templates it creates are very accurate. Really great for odd angle joints. For making joints in larger pipes
if you don't have a printer or plotter that produces larger drawings the software will produce multiple page
drawings that have register marks so you can overlap them accurately...
