Dave I just noticed you're in South Africa. I used to go over there a lot for work, and one thing some members here may not be aware of is that it's sometimes difficult to get hold of things that even in Australia we may take for granted. It can make projects much harder from what I understand speaking to those over there.

The best thing about South Africa (well apart from the women), is being able to go to a game park, look at all the cute little animals ... and then go back to your lodge to eat them For those less, err, "game", when you eat beautifully aged SA beef it makes you appreciate just how crap the meat sold domestically in Oz really is!!

Hi Pete,

It was very difficult to get stuff and expensive as well, it is a lot easier now with ebay and the likes.
I still have to "import" a lot of stuff mainly because the hobby machinist/model engineer just isn't catered for, just not enough of us.

The meat is good and South Africans are reducing their intake, because it is so cheap we ate too much of it, so we all die of heart disease. In the 70's and early 80's heart disease was the highest in the world. Having half a (fried) rump steak for breakfast every day doesn't really do one any good.

I wasn't born here I was born in England, (Leicester) came here in 1980 - on a three year contract,(with a view to stay), never left - I'm beginning to like it here

I think the weather and the life style were the main reasons for staying.

And as long as we beat you at cricket I'm happy

Pete,

I meant to ask what work did you do here?

I'd keep depending on the climate and the beef, if I were you Dave!

I like your machine, by the way.

Thanks drsed,

Wishful thinking

I was hauling plane loads of people between Australia and SA. We'd go quite a ways south on that sector, it was quite normal to see icebergs. Coming back was at night and it was also not at all unusual to see the Aurora Australis. I will never forget one night it was particularly strong, one of the freakiest things I've ever seen. The aurora was from horizon to horizon, and it looked like it was actually going through the aircraft (naturally it's not, it's right on the edge of outer space, but that was the optical illusion). For a number of hours we were immersed in the aurora 360 degrees around us, each wave was like a pulse. Very much like a cheap sci-fi movie really. Quite spectacular anyway.

Yes Capetown is one of my favourite cities, it's all just a bit of a shame about the crime over there.

Pete

Dave,
Very nice work!
Do you have a drawing for this wobbler?
I've downloaded a few, but this is by far the most elegant.
It would make a great first project to do with my grandkids!
Cheers,
Joe,

A few photo's showing the ports (holes)






There isn't an awful lot to it.

Hi Dave'H,

when I read your post, it appeared to be a random posting of something you'd found on the net - nowhere did it say that you had made it. If I hadn't started to attempt to begin to have a go at a wobbler, I wouldn't have bothered to read further, and halfway down the page notice that it's your own craftmanship on display.

I think that if you had opened with "Look at what I made", then the responses would have been much different, and probably more positive.

I like it, I agree that the flywheel's elegant, I wonder about the grooves on the piston, and I wonder do you know anything about Cape Town's Town Hall (which my grandfather is supposed to have been involved in building).

Cheers,
Andrew
