The counter guy told me they can only sell helium to hospitals and doctors offices.
Really? Interesting, I wonder where they get helium to fill balloons then?
Around here, you don't. For at least a year now.
I priced out a bottle of tri-mix (helium, argon, co2) a few months back...that was a reality check! Needless to say, I didn’t buy a tank.
And yet you can buy it specifically to fill balloons at Target? This belongs in a WTF thread.
Hey, I'm just relaying what a counter guy at Praxair told me. I also know neighbors and relatives have been complaining that they can't get helium balloons filled. After a bit of Googling, it is apparently a problem that has been a long time coming.
And current news: https://www.cnbc.com/2019/04/12/helium-shortage-is-hitting-balloons-and-scientific-research.html
It may show up on a website, but is it actually available? Because it isn't for me.
I know a couple of months ago a friend’s wife sent us on a mission to get a tank and we were able to. It was in the card, party, stationary section.
I have also heard in the past that the US is pretty much the only nation where helium is available like this, that most nations it is a scientific or industrial gas not for a child’s play toy.
With the huge reserves the US government used to stockpile almost gone, I think the days that helium that is used for parties are coming to an end for the USA as well. The cost will likely become prohibitive if not actual legislation banning anything but medical/scientific/industrial uses. It seems doubtful that any privately funded companies will ever be able , let alone willing to provide a vast & economical supply like the one we have lost.
The solution for the helium shortage is to start filling party balloons with hydrogen. It is readily available and a real ice breaker at slow parties
Here's a question for the welders...
I bought a set of crash bars for my Connie 14, but they didn't come with any mounting hardware. One of the rear engine mounting bolts gets replaced with a special bolt that's longer to accommodate the bars. This bolt is a special bolt with a hex shaft on one end. I contacted the company that makes the bars (they no longer make em) and they couldn't help me out with the hardware.
One option I'm entertaining is buying two stock bolts, cutting one in half, then welding a section in to make it the correct length. My question is, would this weaken the bolt to the extent that it shouldn't be done? It gets torqued to 44 lb/ft.
Threaded hexagonal rod. Cut to length, thread it on and tack weld into place.
I think you would be better off to cut two hardened bolts. Grind to a point, and tig weld them wih a good rod (E80sD2). Heat the weled area and more to low cherry red and quench in oil when done. You can make sure it is straight when red.
How about all thread, thread a coupling nut down to the right spot and tack weld it then put a nut on the end and tack it.
44 foot pounds sounds like a lot for a bolt that long are you sure it’s not NM’s.... big difference
I thought about that, using an all thread and tacking some nuts on it.
The hex portion goes into a collar which is then turned counter-clockwise to draw the engine against the frame, torqued to 11 foot pounds. Then the nut is torqued to 44.
All thread is grade 2. Can you just lengthen the exhisting bolt?
McMaster has 10.9 and 12.9 grade all-thread. It looks like the hex portion is used to screw out a collar so as to remove the gap between engine and frame. If so, a hex coupling nut on the all-thread would work although you may have to reduce the hex dimension to get it to fit the collar.
Here's another idea. Can you use the stock bolt to tighten the collar against the frame and then replace the stock bolt with a longer one (or all-thread) of the length needed for the crash bars?
Maybe. My only concern is that over time the collar could loosen up. Kawasaki must think it's important enough to be properly torqued or they wouldn't have put such a process in the manual.
I'll try to find someone that can properly weld the bolt and make it longer, if not, then I'll try an all thread route.
Shipped it yesterday priority.
