Stainless Steel Bernoulli Balls and Tesla Dreams
Posted by Paul Woodhouse at April 22nd, 2008
A curious instinct tells me I should make Steph get out more. Whether I give her a key or up her housekeeping are a couple of options I’m pondering.
The problem with her doing bits and bobs for me is that she’s very easily distracted. I should know seeming I’m forever having my tract dissed. Once in a while she’ll concoct a scheme or get diverted by an online interest that is, well, remotely interesting.
Of late, she’s been getting into all things Tesla – the first time she mentioned a Tesla Coil I replied that they wouldn’t come cheap at the Family Planning Clinic. Then again, cracking woofers like that and I should be slightly worried about her tapping me up to be the hamster in this particular Tesla cage:
If you like electrical and scientific wonderments – and if you don’t then you’re a bit odd – the Tesla site I found that on has loads of other amazing Tesla-related stuff you can replicate (or not) in your back garden.
I may show you some of the more exciting stuff at a later date, but something I did come across was these Bernoulli Balls:
And this stainless steel Bernoulli Ball:
Now the weird thing is, round about the same time I was being Tesla’d 24/7 by Steph and checking various Tesla sites out, we received an inquiry at Butler Sheetmetal about a stainless steel ball sculpture that bored little oiks kept knocking off its perch:
Stainless Steel Ball Sculpture
And they wanted to know if the boys could do something to ensure the thing remained upright for long enough for people to enjoy it. It’s not too much to ask, is it?
Obviously, with Bernoulli Balls in mind, I suggested an oversized leaf blower and some elongated industrial straws for balance. Personally I thought it was a bit of inspired genius.
They just told me to stick to the blogging. Fair enough fellas.
Hopefully I’ll have something to show you once it’s done to show you how they did it.
I really don’t anticipate any Benny Hill-esque chase routines as they try to fix it and it goes hurtling off down some field.
Not that any of them would catch it, mind.
Here are some other balls http://www.shermangalleries.com.au/artists/inartists/artist.asp?artist=6&exhibition=112
These were all machined from 316 solid bar (dia 320mm) then welded together and polished. They are all hollow with about a 3mm wall thickness. I used a machining centre to remove most of the internal material before turning the inside then the outside.
This is my main product http://www.keztek.com . It is the fastest and best weld cleaning machine for stainless steel tig and mig welds in the world at present. You can see the finish it gets in the UK on the Ronald McDonald charity panels in the drive throughs. Cleaning the weld holding the little basket on takes 3 to 5 seconds to do. Information is available through the web site.
