Obelisk 2nd Attempt

[Norm]

Hi , 2nd attempt at an obelisk, went for broke this time and decided on a six sider.

First I cut six 10mm square bars to length and bent the ends at 45 degrees 100mm from end and then twisted them leaving approx 600mm from the bottom straight.

As I found from my last attempt these are really difficult to hold in the right position when you try to weld them so wanting to make a few of these I made up a jig from an old gas bottle dividing the circumference into six and tacking on some bars, the main uprights are then ratchet strapped to this. (Note the bottle has been purged as per all the advice on here prior to welding it is half filled with water for some ballast and the damaged valve has been screwed back in) the tops are then pulled together and tacked in position.

I then twisted up some bar and bent up different size hexagons having measured the lengths of side required.


I then made up a little finial for the top, and welded the whole thing together.



This is the finished job, which now needs to be painted.

Nice one
Something slightly menacing about it.
Now make the full sized version. At least say 20m?
Like it.

20m! just about managed this one at 7 foot and I'd need a gasometer instead of a bottle for the jig .

It's the base of the bender I bought courtesy of Astro Al , various fittings go on it to allow tight or radiused bends, It's the first time I've had the space to use it properly and I am really pleased with the results and the ability to make repeat items.

Looks like a well engineered piece of kit.

cheers Seano I was going to make it a bit more decorative in terms of adding a few bits and pieces to it but It is destined to have some everlasting sweet peas and a clematis clamber up it.
If we get some decent weather I doubt I'll be able to see much of it in a few months : on second thoughts I better add something

yes I am well pleased, it's the one I enquired about on the forum a while back to which you responded if you recall, I would love some metalcraft gear but having just built the workshop and aquired some more toys that will just have to wait a while.

Nicely done. I have the same bender and love it.

Painted, planted and just relying on mother nature to do her bit.
