Vintage work crew photos

[Rikk]

No eye protection and a bracelet on each wrist makes me think it's a staged photo. Ah well, at least she has her long hair in a snood.

Many of these war photos of women workers were made to encourage women to join the workforce and, as a result, tried to show that a woman didn't have to sacrifice her femininity while doing a "man's job". They weren't meant to demonstrate proper safety practices.

I'm pretty sure you are on to something there Marv. The acronym on the bottom of the photo seemed familiar to me. After some searching, I found this.

"The National Advisory Committee for Aeronautics (NACA) was the predecessor to The National Aeronautics and Space Administration (NASA)."

I am old enough to have personally known two “Rosie The Riviters”. They are long gone now.

It saddens me to think the men and women who fought and supported WWII are all but gone. They were trying times dealt with by tough people .

eye too, have had 90% of my eye injury's while wearing protection....
as for the QCTP's... Ive not found a china one that you could take off and put back on in the same position.....if I did more I would make my own, but I dont so...it is what it is.
I do have massive respect for those who did this work .

I was looking for a QCTP but could not justify the cost. That money went for other, more useful accessories.

I do not use a rocker with my lantern tool post. I use flat shims on the base this makes the set up much more ridged. It is much easier to set up and get you get very accurate repeatability removing and replacing tools. It also does not change the cutting angles on cutters due to rocking the holder to adjust height. I can take it off and put it right back on with the tool at the exact correct height.

For a lathe used mostly for doing repairs and one of a kind work, I find the lantern tool post is superior to a QCTP for most operations. I wish I had a couple more, if yours is taking up too much room in your shop.

I have one QCTP of my own design. It is small for use on a Unimat size lathe. It works very well. It is 1-3/8” square and it has two positions at 90 degrees from one another. The tool holders have dovetails.

Single Tandem? Bit of a confusing misnomer there?

Single Tandem? Bit of a confusing misnomer there?

I was thinking the same thing, but then I remembers you can have a trailer with single axle , double axle, triple axle, etc, each with a single tire or dual tires. So that would be single single, single tandem, single triple, dual single, dual tandem, or dual triple.

That thinking led me to investigate axle configurations, that exposed this study which I found interesting;

Effect of Heavy Multiple Axle Trucks on Flexible Pavement Damage Using In-Service Pavement Performance Data
Hassan K. Salama1; Karim Chatti2; and Richard W. Lyles, P.E.3
Abstract: Truck axle configurations and weights have changed significantly since the AASHO road study was conducted in the late 1950s and early 1960s. Emerging concerns about the effects of new axle configurations on pavement damage, which is unaccounted for in the AASHTO procedure, have prompted several researchers to investigate the impacts of different axle and truck configurations on pavement performance. However, there is still a need to strengthen the mechanistic findings using field data. In this paper, actual in-service traffic and pavement performance data for flexible pavements in the state of Michigan are considered. Monitored truck traffic data for different truck configurations are used to identify their relative damaging effects on flexible pavements in terms of cracking, rutting, and roughness. The analysis included simple, multiple, and stepwise regression. The results indicated that trucks with multiple axles tridem or more appear to produce more rutting damage than those with only single and tandem axles. On the other hand, trucks with single and tandem axles tend to cause more cracking. Pavement roughness results did not show enough evidence to draw a firm conclusion.

I was wondering what a blowing engine is... found this;

National Museum of Industrial History

Where does the blast for blast furnaces come from? For many furnaces, the blast of air was supplied by “blowing engines.” This presentation will describe how massive engines once ran around the clock to pump the requisite two tons of air required for every ton of iron produced. We will trace the evolution of air pumping devices associated with blast furnaces and do a deep dive into the “Gas Blowing Engine House” in Bethlehem, Pa, which is the largest surviving facility of its type in the world.

Found this video. Pretty long to watch but you can fast forward to get an good idea.
