Round blacksmith tables made from blind pipe flanges

3 legs will be stable on most any surface, 4 legs will tend to rock on anything but a dead flat surface, and you may need to provide some sort of leveling device.

Inclined or splayed, with the floor ends several inches outside the disc will be much more stable. What are you using for the leg material? Most likely you will need two jigs. One to cut the miter/bevel parallel on both ends, and another to hold the leg in position when you tack it. This is likely to be a high stress joint, given the expected pounding. Are you going to add any braces? Can you hot bend the legs into an ell shape so there is more weld area than just a butt joint?

What kind of welding/rod are you going to use? Any thought to burying the welds in lime or vermiculite/cat litter to prevent too rapid cooling and embrittlement?

You've got to ship these, right?

I'd make up a leg that bolts through the hole. If it were me, I'd have two splayed "L" shapes cut on a CNC torch table for each leg, then weld in a cross piece to form a channel and have a bolt on the top of the "L". tell the end use he can weld for re-inforcement.

three legs would be better

I agree.

Well, a bandsaw can cut a miter.

Without question, I will need bracing near the bottom. This is a good point. The welds will fail after repeated pounding, sooner or later, and braces will save the situation.

Most likely I will make the first one with 7018, and I will let my guy do the rest with MIG.

By freight.I expect most to sell locally.

These would not beUPS shippable, 250+ lbs.

This is how these flanges look like:

I would want one leg. Say a 6 by 6 square tube with a flange so it can be bolted to the floor. One is not going to be moving something like that very often.

I do not have such a tube, but I do have pipe. I cannot really afford to buy new steel from dealers.

Pipe would work.

You might be better off listing different types and not weld the leg (s) on until the customer decides what he wants.

Dan

That's a good idea.

Speaking as a blacksmith...

Center post, ca. 3" pipe. 1/4" plate disk or square for a base. Gussets to brace the welds.

Make one for a demo. Let customers decide how high they want it, cut the pipe to the length that suits them.

Some will want to bolt to the floor (smaller base), some will want to add casters (so need overall height lower). Some smiths stow their gear under cover, wheel it outdoors to work; a square base plate will be easier to move with a hand truck.

Better yet, sell as is to blacksmiths who will polish them and make fancy ornamental legs for coffee, hall or telephone tables. Massive but attractive and unique furniture is a sought-for asset in a house with a big dog.

Three legs might not make for a level table top, but at least it won't rock back and forth.

I've dissembled tables when people move from one house to another. A couple bolts, nuts, washers.

Right. And with some shims you can easily level those three legged tables.

Dissembling is bad!

I've had a chance to help LDS members move house. When they move out of my area, I help dismember them.

My back hurts just looking at them!

My back actually hurts. And that is fron lifting smaller flanges, which I scrapped.

i

Only use (3) legs

Then it will never rock.

Looks like there is a consensus...

I use a collection of those small blanks with my hydraulic press. They are flat, easy to stack, helps a bunch when adjusting heights.
