@Peechy, thanks for the heads up. I just purchased the file and cut it out in a small scale form as a test, and will put one together soon. Will post pics when finished.

Still in progress, but you get the idea. It is much easier to fit up. Well worth the $6.45 from makecnc.com

I have learned a lot from this thread, not just fire pits, shapes, names of shapes, history etc... but also about copy-writes and patents.
And how to act mature and stand for what you believe in.

Thank you spider.

Just curious, how many of you are building these using individual hex and pents vs a "fold it together" design where many of the hexs & pents are cut as one piece.

It looks like a lot of work using the individual shapes.

I'm very close to building my first one and have drew everything up in Coreldraw as a fold together design to give speed of assembly. Got to say I was shocked at how much cut time Sheetcam is estimating with mine. I have to reduce the cut speed to 1100 mm/min to prevent table "shake" and it's looking like nearly one and a half hours cut time for a 750mm diameter pit.

With material cost plus cut time plus assembly time I can now see why some members have said they don't bother with these and can make more dollars with less complicated cuts. Soon to be found out.

I tried it by folding the pieces ,to much grinding . I prefer make them out of 1/4 or thicker so I cut individual shapes and I can assemble my way faster then bending nd grinding butch dey

Thanks Deyhard,

that's the bit that has me worried. Feels like gambling in a high stakes poker game at the moment. I hope it turns out to be who dares wins and not who dares turns a sheet of steel into scrap LOL.

I've made several by welding the individual pieces together. I've not timed myself but it doesn't take too long. If they're all cut the same size, it's a piece of cake. We never use a new sheet (10g) for these, just when we have some space left over from a job.

Thanks Allen,

I'll have to give both methods a shot. If the first one sells for a price I'm happy with I'll try individual hex and pents for the next one.

i cut each panel and welded it together. it took a solid day for me to tack it all together. then another day to weld up all the outside edges and grind the welds down. 5 1/4" edges gave me a ball that was 25" tall.

An 8 hour day at $60/hour shop rate (some are higher), x2 days = $960 in labor, without design time, material, cut expenses, finishing, etc. I'm not saying that's a BAD thing...just how the math is working on my end. Guessing...what...$1500 or so rough retail cost for one? Does that sound about right for a 25" unit, those of you who have done/sold them?

I've seen them here for $450....... 10 ga. I think.......I don't think they were welded on the outside....I think they were stitched on the inside. But even so, as cool as they do look, I don't feel there is enough margin to be worthwhile.......haven't tried one yet, I might someday, but I'm not in at $450 retail.

Matt70Chevy,
Am I reading that right? A solid day to tack one together?? Holy mackerel! Are you gas welding it? I can't say exactly because I've never gotten to weld one up without interruptions but I tack weld the inside and then when it's all together stitch weld the outside in probably 2-3 hours.

i'm wrong....or said it wrong...that was cutting it and tacking it. i spent the next day welding up the outside edges and grinding/blending down the beads. i'm no speed demon but i'm not sure where I could've made up any time. maybe on the fit up and tacking it together i could've saved some time
but i wanted to make sure each panel was dead nuts.

@Matt70Chevy, nice job on your pit. Would you mind sharing just the pedestal file without any artwork on it? I am finding the one I used from earlier posts is just too wide at the base. It looks as if you have figured out the correct angle on yours. Thank you.

I had to build one of these once i saw this. Here is my take on it. 50" Tall on the stand.

Lacking in enough brain power to accomplish this on my own, how do I calculate how much to resize the individual panels to come up with a 60" diameter "soccer ball"?

Thanks.
