Do you know this device? Pulvis-R - Restoration

Pulvis-R
This device was manufactured around 1930 to spray the insecticide DDT. The renovation was commissioned not for the subsequent use of this device, but as a reminder of our history when this device was used. It will then be exhibited in the museum.
Flour was used for the demonstration in the video :)
Something from history :
DDT was first synthesized in 1874 by the Austrian chemist Othmar Zeidler. However, its insecticidal effects were not discovered until the Swiss chemist Paul Hermann Müller in 1939, who was awarded the Nobel Prize in Physiology and Medicine in 1948. Since World War II, DDT has been used on a mass scale. It served as a preparation for the control of harmful insects in agriculture, but especially for the elimination of mosquitoes in tropical countries.
DDT was brought to Europe by the US military. The prisoners of the liberated concentration camps state in their memoirs the goodness of this powder, which effectively and immediately killed all insects.
Back in the 1960s and 1970s, DDT was also used in Czechoslovakia, for example against everything, and could usually be bought in a drugstore. It was made by Spolana Neratovice. It was cheap, very effective and chemically stable, it did not decompose. When it was poured on the bottom of the cabinet and covered with paper on which the laundry was, it touched the insects by touch for another half a year.
DDT is toxic. A lethal LD50 dose of 135 mg / kg in food was found in laboratory mice, 87 mg / kg in rats, and 1500 mg / kg in humans, although much lower values ​​have been published. It can also penetrate the body through the skin; The LD50 in rats in this case is 1900 mg / kg DDT is highly toxic to aquatic animals despite its low solubility in water. The LC50 lethal concentration varies according to the species of fish from 8 to 100 μg / l when exposed for 96 hours.
Small doses are enough to kill insects. For houseflies (Musca domestica), the LD50 is reported at a 24-hour exposure of approximately 0.033 nag per individual.
The effect of DDT on the hormonal system
Use of DDT in the US military during World War II to protect against malaria or typhus
In 2000, a study was published showing that the breakdown product of DDT acts as an endocrine disruptor that disrupts androgen function. In rats, it showed inhibition of hormone binding to the so-called androgen receptor. In 2005, the journal Environmental Health Perspectives reported an increase in the incidence of so-called intersex frogs due to the use of DDT. In 2006, the Journal of Andrology conducted a study to reduce sperm motility and increase the incidence of defective sperm in men depending on the level of DDT metabolites in the blood.
According to American research, exposure to DDT during puberty increases the risk of breast cancer by about five times, which is attributed to its ability to disrupt the hormonal system.

Not only did you restore the tool, a DDT disperser, but provide some historical information also, super job. Thanks for sharing this video with us. Stay strong and mask-up "again", for safety sake. 🇨🇱🇺🇸🙏😁 Paul

Once again, this is the best restoration expert on the planet! Keep up the excellent work! You’re teaching the rest of us that old things can be made new again!

This was very fascinating. Read through the history of DDT and I didn't know most of the information you provided. You are an amazing craftsman and I always stop what I'm doing when a new video comes up for your channel. You did a wonderful job with that restoration. Thank you.

[@johnpatrickcryan6182]

Ah yes, we used them up to the mid to late 70s, the one you rebuilt was for the shore line, they make another that fit in the bed of a truck, 55 gal. that sprayed the camp grounds, summer job, I should have died long ago, Great Job, you guys are keeping history alive...

[@karunakaranjoseph958]

Wow! Such a complicated and painstaking restoration...at first I thought it was a portable cotton candy machine then I assumed it was some chemical mixer . The functional aspects of this contraption is very effective . I thought your gonna make a new impeller fan but the blade joint was perfect and since it's a hand rotated operation it doesn't need balancing ....overall a very impeccable workmanship in the restoration. Thankyou very much for sharing this video.

[@patjohnson3100]

Another excellent restoration. At first I thought this was for planting seeds, and it looked like a complicated restoration. I thought it would be hard to restore the broken impeller, but you made the entire project look easy. Thanks and smiles from the USA.

[@VeradonaRestoration]

Thank you so much my friend :) Radek

[@georgecunningham9175]

Another fantastic restoration! But I must comment that no matter the challenge, no matter the desire to create entertaining and absorbing content, no matter the possible return, your health must come first. Having watched almost all of your videos, I know that you always take precautions, but please consider the possible accumulative effects of working with nasty, lethal substances. I look forward to continuing to be amazed by your creativity and craftsmanship and would hate for you to be unable to continue doing something you have such an obvious passion for!

[@VeradonaRestoration]

Thank you for your concern. I try to work safely.

Hello Radek As I have already wrote to you numerous times that I love your restoration but I have noticed that I also love your way of finding solutions for missing parts and doing it perfectly, your photography is amazing and so is you humor, as always very well done on the same note you can tell Veronica that her recipes are great, I have already tried and enjoyed her food,

It is a hand cranked DDT pesticide blower. the DDT pesticide powder was placed into the large cylinder and metered into the blower unit on the left hand side, it was as lethal for the operator as the insects, just much slower!

Wonderful job on getting that thing clean. Just goes to show how much poison was sprayed on the food we eat and in the environment in general. Looks beautiful now.

[@VeradonaRestoration]

Yes, I agree, thank you

[@normahutton1560]

WAS sprayed!! Don't talk in the past. It's even worse today. Have you looked at the soil of an agricultural farm. I did a few years back. The soil was dead. Things are still sprayed on our food, it's expensive, and poisonous, and or genetically modified, but like Africa we have no say. We are dealing with big pharma now. The stuff they use now combined with genetic modification is probably far worse than DDT.

[@walterengler5709]

Not only the clean which took forever on this one .. what a load of work. But the repair job on the blade to replace the missing vane was wonderfully done.

Yes, in my younger days before DDT was banned, i had a smaller version of a similar sprayer. DDT was good stuff but only one problem, it was deadly. It was found to cause the Great Eagle eggs to be crushed easily, the USA just about lost all of our national birds. It's a wonder I'm still alive. What do they say? Live and learn. Great restoration.
