Thanks Phil and Frank,
I wasnt inteeding to insult your explanation Phil, its just that the first time you hear the idea behind it is sounds impossible. I'd think the guy that came up with the idea got a lot of strange looks early onlol. 3000-9000 litres an hour thats way more water than I would ever have guessed.
Hi Greg,
Just how big is a collector tank that has its own qty guage?

Hi Phil,
Thanks for the photos. They all look like fairly late, fairly high capacity machines from the end of the horse drawn vehicle era. I was surprised to see the advertised output of wagon wheel spokes from some of the spoke machines from the 1890s, e.g. an advertisement for the Egan machines in 1891 claimed an output of 2400 wagon wheel spokes per day. Assuming a 12 hour working day, that's 200 spokes per hour. Wonder if your Defiance would match this if set up for serious production work? The output from the spoke making machines used by the motor industry in the teens and twenties must have been staggering.
Ford alone produced close to two million vehicles in each of the years 1923,1924 and 1925, after which they changed to steel spoked wheels. Since the vast majority of the wheels each had 12 wooden spokes, the total number of spokes machined per year for Ford alone in these three years (and the amount of timber used specifically for this purpose) add up to some fairly large figures.
Once again, thanks for taking the trouble to photograph the machines for me.
Regards,
Frank.

Based on those numbers, and assuming the spare tyres were not mounted on hubs, that's 96 million spokes/year just from Ford, or over 313,000 every working day. Ford only had a 40% market share, so that works out to over 784,000 spokes a day.
The individual machines we watched might be able to get 2400 spokes a 24 hour day...thats a 36 second cycle time with no breaks and no operator fatigue. I think there were three separate operations of maybe a minute total, but that would take some real old fashioned hustle with its attendant injury and burn-out rates.
The above production figures for Ford alone, assuming the perfect production numbers an no break downs would have required 130 stations running 24/7 and the related dimensioning machines. And two boxcars full of timber per hour. Phew.

HI Stuart
I finally got out and took a photo of the injector. This is the one I donated for the cause.
It is a 1 1/2" Brown Auto Positive and before anyone asks it was upside down when I took the photo.
I put a Zippo lighter next to it for scale.
What is disappointing is that one of the cones is missing (it was complete when I donated it) so I will have to locate / make another one.

As work is piling up I have decided to concentrate on finishing what I have started. My main project at the moment is a Worthington Simpson duplex double acting Steam Pump. This pump feeds water to the boilers to replace the water used to generate steam for the engines.The main repair is the pivot block situated on top of the pump. Part of the casting had broken off and the bores for the pivot shafts were bored out of alignment. I needed a new casting so covered the broken areas and and sections that needed to be machined and sent it off to be used as a mould for the new casting. So far I have only machined the datum surface on the new casting and until I can work out the original dimensions so as I know what it should end up like. I have located the original drawings for this pump in a museum in England but the lovely lady at the museum refuses to send me a copy.
I removed the valves from the water side of the pump and found one of the threads they screw into is less than acceptable. I feel a lot of head scratching coming up to work out a suitable way to repair the thread.
I don't suppose anyone out there has a 2" UNEF 16 (Unified National Extra Fine) tap I could borrow.....

Hi Phil,
Thanks for the picture, not that big really when you think of it pumping 150litres a minute.
And did the charming lady give you any reason? If she isnt going to let anyone see it she may as well burn it. Should have let us know earlier, we could have sent BT on a side trip to have a word with her!
Damn I broke my last one yesterday

Can we come again?
Four hours or so, was just too short to take in the enormity of the whole site, may we come back another time better prepared?
Maybe soon the Ballarat Brewing company will be set up looking for professional taste testers? And the confectionery factory. All missed last time around.
I can still taste the yummie meat pies, with just a hint of horse manure fragrance assailing the nostrels, floating over the top, bloody hell, magnificent.
Can we? can we? please. please?

You have to remember also Stuart that they can move that volume of water while pushing against 130 lb/sq".
The lovely lady told me I could pop in anytime I liked and when I explained where I live she just reiterated that I could pop in anytime I like. It's fantastic that there are museums around that collect things and then only give access to the locals.
This pump has now become a challenge as it has been machined wrong from the last person to give it a rebuild. Consequently I haven't got much in the way of datums to measure off.
I love a challenge!
Thats a bugger about breaking the last one you had...was that the one you had on a bit of string hangin' around your neck at the scraping weekend.
Would you believe I found a bag of 'hens teeth' while looking for one.
Hi Ken
would you believe we did a very full 6 1/2 hours that day and you are right, there is still a lot we missed.
I would be more than pleased to do another but I have probably worn out the free passes.
The scraping class reunion is being planned for September next year and if all are in agreeance then we will do an overnighter at 'The Hill'.

Phil,
where is the museum located and what is it called?
Do you have a reference to the actual drawing? Museum catalogue number or some such thing?
I know quite a few people in the UK and would be delighted to send someone on a visit to scan or photograph the drawing for you.
