Bending Threaded Bar

[ikearns]

I need to make about 20 U bolts to anchor wooden posts onto a metal pole framework and I cant find these readily available at a suitable price so am considering making my own.

Will an over the counter blow torch from the likes of Screwfix be enough to allow me to bend M10 threaded bar??

TIA

Ian

Yes, as long as you don't want a tight bend.
Have you got a local blacksmith, bet he wont charge you much.

Likely to snap the rod, rethink your solution, simple is usually better, maybe just drill the metal pole and bolt or screw thru.

There is a legacy corrugated metal fence in situ and the poles I believe are old scaffold poles which are sunk into the ground with a shuttered concrete base about 12" high. It would be an absolute ball-ache to try and break it all out plus the poles are rock solid and give a decent anchor point.

It has been there for about 40 years!

The poles are about 50-60mm so it was our plan to use them to tie upright 4" posts onto and then put a standard larch lap fence along

Can you find an exhaust clamp the right size? these things http://www.clampcouk.co.uk/exhaust-repair/exhaust-clamps/exhaust-u-bolt-clamps.html

Looking for Blacksmiths / Ironworks around my local area is drawing a blank.

An idea that we considered but couldnt find them deep enough, the straight bar element is too short

You'll need a large gas nozzle that runs on propane to bend this......the sort of device that has a 1" barrel.
Heat up with a firebrick surround if you can, and best to make a bending jig out of one of your poles.
The exhaust clamp is an excellent method if you could adapt that!

What about using that flat metal strip with holes? That'll bend cold round a piece of pipe in a decent vice, with a bit of hammer persuasion. Just clamp the strip vertically with the pipe hz. in the vice, and work it round, angling it to get more bend.

Quick and easy.

The strip is a good and cheap solution but I can imagine the stress on the holes that you screw through is a weak point. Will a good fall back

Take a look at Ariel pole fittings.
Pole clamps might suit.

Will do. Hadn't thought of that, thanks!

I was thinking of something a bit heavier than the one linked to above.
Something like this.

They do it in a couple of lengths.

C.P.C will have the aerial components and sell them individually.
