A long time customer called me about buying a tank head fire pit, I referred him to several local tank head factories that sell ready made pits.
Several months later I get a call asking if he can drop off a 72" tank head to have some modifications done. I said sure and what needs to be done.
It needed a ring around the top and a base BUT he wanted to have it hinge...
I thought that was dumb and sort of pointless but it seemed like fun.
Well the hinges kicked my ass for a few weeks, I never did figure out how to design the hinges from parameters, I watched a hundred videos but in the end I just moved points in OnShape until it worked...
I made it harder than it likely needed to be because I wanted the hinges/lift to be hidden and raise up to clear the stone work around the base before tilting.
I had the rings rolled, that wasn't a problem.
I cut all the parts on the CNC plasma for the hinge. I drilled all the holes to loosely fit 1/2 grade 8 bolts as pins. I flipped it all upside down and started fixturing and tacking the brackets on.
This is when shit started descending in to chaos, I think I got too hot or the bending over on my new back was really tiring me out but this thing would not hinge... The linkage was bound up which made no sense but is likely to happen when you only r&d in CAD.
I did, I really think the problem was not lifting symmetrically on the ring, when I had it upside down and just manually trying to lift one side of the ring opposite the hinges it was causing the linkage to reverse over center. With a jack central under the dome that was not a problem.That's a cool looking deal. Did you end up figuring it out? With the lower linkage dropped below horizontal, it looks like it will actually try to force the stand further into the dome for the first fraction of an inch of movement, before swinging open as you would expect. If your tacked tab on the left was like 3/8" higher on the ring so that linkage was level, might work as expected
I would like to figure out exactly how to design the required hinges from a parameter set though, any suggestions?Ok I shoulda waited . Awesome
I know a guy in Florida looking to make a drawbridge for his alligators or something.I would like to figure out exactly how to design the required hinges from a parameter set though, any suggestions?
The reason (his not mine) is that his house is on a cliff on possum kingdom lake and the wind is notoriously blowing hard and in one direction so this will be installed to prevent the wind from blowing the propane flame out.Cool
but why?
That looks awesomeIt's my daughter's 4th Birthday today, and I said I would bake her a cake.
For as long as she has known a her colors, she has declared that her favorite color is rainbow.
So I baked her a rainbow cake. Made it from scratch because all the box mixes are terrible.
On a related note. It really sucks for my kid that the gays have hijacked the rainbow. It is a pain in the ass to find rainbow shit that isn't politicized and all about being gay.

As per usual with this guy he asks NOW if it can have a ring around it like this72" fire pit is pretty fuckin big, wonder how much propane it's gonna use at full chooch?
Good on you for making your kid a cake.On a related note. It really sucks for my kid that the gays have hijacked the rainbow. It is a pain in the ass to find rainbow shit that isn't politicized and all about being gay.
Try and sell him on something classy!As per usual with this guy he asks NOW if it can have a ring around it like this
Fuck me, I'll order the ring on Monday.
We started with a silhouette ring but he didn't/couldn't decide on what he wanted cut out so solid it was...Try and sell him on something classy!
Hope you appreciate what I had to go through to get this pic.
