When doing work on my house, I've run into a plaster reinforcing mesh at the corners of some walls. That stuff is a bitch to cut cleanly through to do a patch. It wants to take the whole wall with it.

the technique is called slit and stretch. the video shows the machine in action, this link has a simplified animated drawing that is much clearer. Here's one more animation that could be helpful.

This animation is the best of the three links.

The interesting (and obvious in hindsight) thing about the youtube video is how slowly the supply side sheet is fed into the machine compared to how quickly the expanded finished product comes out. It looks like the sheet being fed in is not even moving while the mesh coming out is clearly moving, albeit slowly.

Although this really does exist, I don't have one and I want one...

The link below downloads a 23 page pdf for how to construct it.
Maybe V can make one for each of us.

Build Your Own Vertical-Axis Wind Turbine On The Cheap

Quote:

The Zoetrope is a vertical-axis wind turbine (VAWT)
made from materials commonly found at your local hardware store
and a few easily purchased online, and Applied Sciences has made
the decision to “open source” the turbine for everyone who wants
to try their hand at making one. With videos and a downloadable PDF construction guide,
it looks like anyone with a menial amount of handy person abilities could make one for themselves.

During testing, the turbine was witnessed outputting approximately
150-200 watts of power in a windy period with gusts reaching up to 20 MPH.
Under its current design, the actual average output is difficult to gauge.
This is because certain parts in this turbine were tailored to withstand gusts of up to 60 MPH,
conditions which are common here in the Northwest and likely to burn out more sensitive parts.

AFAIK, there's no non-surgical way to cure Cerebral Palsy, let alone any way to cure it, but if one became available, I'd go for it - such as injecting stem cells directly into my cerebellum causing motor cell regeneration.

Ok, ok. I realize this post is not about an actual product, but still, it's something that should exist.

Shaw, I like your thinking.
Too many male designers methinks.

I may have made this suggestion before,but it was orininally pre-Cellar days, so it bears repeating. It may only be of UK use.

Hair collar length? Too short and fone to effectively tie up?
Windy walk to walk?

HAIR SNORKEL.
Air not hair.
- Tube only
- Add goggles to protect eye amke-ip leaking at the corners
- Full face to retain moisture - guaranteed never to mist up due to SG technology
- Niquab style head covering as alternative to snorkel but please be aware this nay draw unwanted attention.

NB - ladies with thinks hair or longer than bobs just tie it up FFS.

Don't ask me why I think this should exist ...

Someone should design a normal household toilet (1.6 gal/flush) with... wait for it....

:urinal:a built-in urinal for males (< 0.6 gal/flush) to save a gallon of water each use.

The sink is right over there!
