The horrendously invasive bamboo that my neighbor and I have been collectively trying to kill off is now in full flourish again (I am honestly amazed how hardy it is, even my picea abies saplings have been chastened by this winter) which I'm taking as a sign of spring, albeit an unwelcome one...

The heat treatment processes which results in full softening ("annealing") only happen at about 650°C upwards (just shy of red heat) in carbon steels, at which point you'd be well into pyrography temperatures, even going up to 350°C you'd be looking at the hardness not dropping much lower than...

Wire which has been heat-treated to give it a specific tensile strength range for producing springs, usually each diameter is available from stock (via specialist spring steel stockholders) in a variety of tensile strengths to allow manufacturers to fine-tune the characteristics of a spring...

Highly unlikely without finding someone breaking a machine for spares. If it's fractured but not actually broken into pieces (or even if it's in bits but only one or two and you still have them all) then it's an excellent candidate for a brazed repair.

I figure that it might be worth turning this in to a build thread of sorts, so to start off I might as well go through a bit of the design process I've followed. Initially it was just a case of throwing together a vague idea of how I was thinking of assembling it from 90×90×5 square tube, and a...

This Info Sheet from Boston Gear is a great starting point... There's also a link in this thread to the online version of Machinery's Handbook, Pages 2125-2135 (2131-2141 if you're typing the page number into to skip to them) will give you a perhaps overly comprehensive overview of everything...

It depends what you're using it for, how much force is being transferred, what kind of speed it's running at, and how much/little backlash you need in the mechanism... It's hard to say for certain without knowing the application, but as a rule of thumb it works something like this: Slow...

From what I saw in industry, doing really good CNC in wood, is largely down to balancing the understanding of the Toolroom and Programming side, with an operator who is observant and knowledgeable about the timber's characteristics and machine operation who can alter the parameters on the fly...

Yeah, I can entirely see that happening just like that... I'm not sure what data they would be harvesting in order to pay for that discount, but you can bet that the operators of the schemes would be.

This has turned into a collection of random thoughts on CNC stuff in terms of both woodworking and hobby stuff. Random Thought One: It's very relevant to professional woodworkers in a production environment, but is increasingly in reach for small businesses and artisans if they have a strong...

Bonus! This is a major digression, but an acquaintance of mine who develops embedded systems for building automation, has an RFID microchip in his hand which controls lots of aspects of his home. I asked him how he got it, and he explained that it was very expensive to get one implanted...

Might have fixed without sealant (or buying anything). Speaking to a friend who works in the Teflon coating industry last night, he reminded me that PTFE self amalgamates under even fairly moderate pressure, and suggested I just crush a bunch of plumbing tape in a vice. Had a crack at...

Whilst I don't want to drag the thread off course too much, you're right that it's pretty much a "Go Big or Go Home!" strategy. Arup Partners, Mott-McDonald and Mondragon Corporation are all huge and extremely successful businesses which are employee owned. As are Lush cosmetics, and closer to...

I don't believe that this is a thing (certainly it's not common), as bolts will be heat-treated post machining to achieve their specified strength characteristics, and are generally rolled rather than cut (which means that blanks from bolt production are not suitable for cutting threads into)...

It's funny how strongly people feel about preserving their legacies... A business contact of mine caused serious (but thankfully, temporary) ructions in his family when he revealed that because none of his children wanted to join the family business and learn it inside and out, he had altered...

Recently got given a dishwasher with a small but noticeable leak which the previous owner had not been able to trace. After running it a couple of times jacked up on blocks with a bucket to catch the drips, and taking Thermal Images with my phone (actually a useful feature, which I totally...

This speaks to the one thing the NHS does really really well... It's extraordinarily cheap compared to other comparable systems in other parts of the world, and manages to achieve very good overall outcomes, and somewhere between adequate and outstanding for almost all patients on what is...

To a Brit, that sounds like a case of confusion over names... Nomenclature wise an "Urgent Care Center" in the states, which you'd expect to have X-Ray, triage based on severity etc, would be called a "Minor Injuries Unit" here. But we do have "Urgent Care Centers" here... Which are...

I had seen those folding engine cranes, which would certainly be less of a space hog than a fixed leg unit, but couldn't quite work out how one would fit into my desired layout easily. As compared to losing 150ish mm off the width of the workshop, which is not nothing, but wouldn't be felt in...

Previous thread had a good number of options, including a couple more people who are pleased with the isotunes that @samhay has linked to. Also, beware of "noise cancelling" headphones as they're not actually capable of meaningful hearing protection, passive ear defenders/plugs with a seperate...
