How to bend 1/4" plate into 18" radius?

I hope yaw know that huevos are eggs!!

That's great! I didn't catch that. Laughing.

My wife is frying my huevos right now, so off to breakfast I go.

Huevos, cajones, brass ones, makes no difference, the Kioti has enough of them to bury the bucket!

Traction is my biggest challenge with this type of work, though I could use more weight on the front too.

I also immediately thought of using a torch and heating one side and allowing to cool. You can bend some serious steel with a torch.

I was kidding about the English wheel and my HF press brake is too small to bend more than a foot of 1/4" at a time too.

So yes, it appears that if bending is involved that I'll get a metal shop to help.

I sell for a large machine/fab shop and this can be done on a press brake, bump method. Another method we use is a heavy duty roller. If you can find a fab shop ( or someone that manufactures tanks, like transformers for example)that has a roller this would not take long to do. Several passes on a roller and you would have the 18" r.

I saw a similar project on a rear scoop
where the part was scored with a cut off wheel every 3-4" lengthwise about 1/8" deep, heated, bent and the scores were re-welded shut. It turned out almost perfect. It had to, The scores can be made nearly exact. For the trouble I would have it rolled at a fab shop but if that's not in the cards, Score it.

Thats a good idea there. Some slicer wheels for a 4-1/2" grinder should make short work of the scoring.

Maybe use the scoring in conjunction with other methods to help control where the bends are made.

Why not use something like in post #21? It appears that no bending is required.

I haven't seen any need to have a radious on the "stump bucket" based on the other designs on the net. Why go round?

I have a shop down the road that could do it easily and they are a fairly small shop. I would call your normal shop and ask if they can do it, or if they know someone who can. They probably know who does what in the area and you may get a better price if "Mike from Jim's metalworks sent me over"

Straight bucket sides would certainly be easier to fabricate and most stump buckets are made that way. I originally liked the idea of round after hearing complaints from some stump bucket owners about how soil would be jammed into the bucket and be difficult to dump. I cannot remember exactly what design had that problem but it was a straight wall type.

Still, as I ponder the hassle involved in getting a big piece of 1/4 cut to shape and then transported to an as yet unidentified metal shop with big rolling equipment and then picking it up etc etc, it does seem like it would be much easier to just get a half sheet of steel and cut it up for a straight sided bucket. Or, to start with a length of 36" pipe and cut it into appropriate pieces for reassembly (still haven't taken time to figure out the geometry of the cuts though I imagine it is obvious to some of you).

Another thing, a rounded sided bucket would not have the same prying strength as a straight sided of the same height. It also looks like there is a whole lota prying going on. Save yourself headache and go with the straight sided....the manufacturers that have to uphold a warranty do.
