Bending conduit…A bit different

[Knobhead]

Not a job of mine but was asked about making a frame out of 25mm conduit. Not a single wire involved in this project.

What ID radius can you bend 25mm 180° to using a standard Hilmore bender?

Nothing to do with sledges or anything along those lines.

I have measured the former on mine, but mine has only the 25mm former, is this any use ?

Dia = 220mm

sounds about right i got 250mm using me fingers,

It was 25mm I wanted.

At long last a dimension I can work on.

This has got to look right, not for my sake but my friend's reputation. I can now do the rough drawings to provide the overall dimensions. A mil or two either way he can cope with in the fabrication work.

I’m not having anything to do with the project other than advise and pre production outline drawings. But I’ve a horrible feeling I’m going to get a MIG welder shoved in my hand if he gets the contract.

Plumbers forum? For conduit!

Aye, apen.

But I do known plumber Dave, the man is a true craftsman! He is!

it seems i got the complete wrong end of the stick in my initial reply. i have however been able to confirm spark 68's measurements. 67.5mm is the measuremtn fro the inside of bend to the back of bend. so from the last point on the former horizontally, to the first point on the former that is vettical. So to find the measyremnt tony is after, it is the measurements i gave x 4. so 67.4 x 4= 270mm. to find the inside measurements, -4x the conduit diameter, in this case 100mm. so 270- 100 = 170mm.

i havent got an M20 former to hand in order to check this theory, but if anybody has, could they please give us the measurenments.
