The Bucket Foundry

[Flettner]

Slider update:
Did an exhaust cradle/brace to tie the three exhausts together and then have to rig up a rough coolant system. With the pressure of popular demand to see (hear) it running in this state, this should be enough to give it a free (not connected to a dyno load) run. Probably do it next year sometime.

After this intermediate thrill, I guess it's back to the completing the pipes and sorting out the dyno.

From little acorns do big oak trees grow.

No, it's easy these days, the skill has been taken out of engineering,,,, just press print.
I'm told, people like us aren't needed any more.

Looking like that, I should be able to hear it running from where I am, sitting here in the west-european winter.
And you're damn right about the 'joy' of making exhausts for a living. I've made more than I care to remember but only because on many occasions I didn't want to wait for someone else to make them, and sometimes because I wanted to keep the pipe dimensions to myself for a while. Pipe building has never become a hobby of mine.

I'm forever grateful that my dad not only let me study but also taught me how to get my hands dirty without losing my fingers.

Frits don't shoot me after only reading the first paragraph, read on until the end.

Nothing wrong with that first paragraph, except KC's remark that we may never know the full story. We know the full story about the Maxtra-Haojue scam all too well.
It began when Haojue contracted none other than John Surtees to supervise their intended 125 cc racing activities. John was about to use a very promising twin-disc engine, designed by Dolph van der Woude (who also designed the Aprilia RSW250) and built by Thijs Hessels, with support from Jan Thiel.
But then Witteveen talked Surtees out of it and instead convinced him to use the Maxtra engine, built by Witteveen's friend Franco Moro.
And the rest, as they say, is history, with Haojue finally going to court, sueing Witteveen.

I was meaning just the mentioning the macbeth name.
Why do so many people go through Surtees?
Anyway, its a nice write up i had never seen before.
With some long overdue kudo to Mr Jan Thiel.

The guy on the right says, "any more shit riding from you and you're gone, ok?".
The Guy on the bike is thinking "oh do piss off".
Jan is thinking " is this guy for real?"
The guy on the left is thinking "this is embarrassing, I'm going to keep out of it and just smile at the camera!".

"12+1". GP titles, 90 Grand Prix victories, spanning three decades, He did okay most days i guess.

Will, I just discovered (honestly!) that if you click on a picture, it's description is displayed below it.
Could be useful for those of us who aren't old enough yet (or too old already ) to recognize racing celebrities.

didn't Angel's son do OK as well?

Well that's a shame, It would of be a interesting engine but I did wonder when looking at a plan of Yamaha twin disc 125 of the 60's wither the two intake steams would interfere with each other?

Likely far less problems with this than the asymmetrical lntake disc valves traditionally have with a disc on one side.

The exactweld engine
The same two guys made the chassis for the Quantal Norton that won the BOT at Daytona
(Surtess was in on that one too Frits)

[Grumph]

I've always looked at the Exactweld and thought that I would not like to pull a spark plug in a hurry - or lift the head between practise and a race...

[husaberg]

- or lift the head between practise and a race...

Probably way faster than you think it;'they just happen to come off with the whole steering head and forks as well.
From memory the Honda NR500 was a full engine out then new engine in for a spark plug change.
One of the other british tandems of the era likely Armstrong or a waddon (i can't remember which)also had the expansion chamber exit in the steering head as well.

I realise that - but there are a lot of fasteners, and it would be hot. Strip one of the threads and unless you have a spare you're fucked.

The Roberts plastic fantastics were quite a bit better for access. Plugs no problem. Engine service, three through bolts out and park the frame on a rubbish bin...
