I designed, built and welded this solid 1/4” steel forge. All dimensions are shown in the attached images. I am wondering value? Maybe someone near me might be interested?

 

Thank you

That's a difficult question to answer.  That design would have limited appeal for me.  The fabrication looks fine, but the dimensions and material thickness are not right for my needs.

Without calculating anything I'm guessing it weighs 50 pounds or more.  In my opinion even 1/8"  thick shell material is overkill.  The outside width is about 7.5 inches, (7" interior width)  so if we add the typical 2+ inches of insulating blanket and refractory material, we're down to about 3 inches of width in the chamber.  If the perimeter is a square then the height is likewise 3 inches or less after adding insulation and refractory.

The length is excessive for anything but very specific work, such as decorative twists on long (and straight) stock.  When using a hand hammer it is typically difficult to work more than about 6 inches of stock before it needs to go back into the fire.   Heating more than that can be wasteful at the least, and repeated re-heating to forge temperatures can actually have a negative impact on steel - especially high carbon steels.

There are more burner ports than I would use as well, although the unneeded ones could be ignored when lining and just covered.

So, as far as value goes, that depends on the end user.  For me it would have little value, but if you could find someone who needs to heat long straight stock it may be worth a bit.

Have to agree with Buzz.

With such a long and narrow usable volume, I think you would also have issues with back-pressure on the middle burners if you had all 5 burners going at the same time.
Also with less than 4" top to bottom (once lined) it might be difficult for the Fuel/Air Mix (FAM) to fully combust before it reaches the surface of the stock you place in the forge.

You might be able to use it for heat-treating if you had small enough burners.

Was there any particular reason why you picked these particular dimensions for your forge, or was it based on the materials you had to hand?

No , the layout just popped into my head. I had the material hanging around and decided to bang it out…
