What I broke today...........

[Arc Tourist]

Today I introduced our bush hog (rotary cutter) to one of our garden hoses. The meeting did not go well.

Been there, done that, but easier to remove than barbed wire.

I'm sure he's got some spares for those.

Was he ever qualified to operate such equipment ?

 

[Onoff]

Hopefully not but...

Strimming with my brand new DUR368AZ, 36V Makita brushcutter I hit a hidden stump when finishing last night.

It doesn't sound right now & vibrates more. Had the tri pointed blade on. Sounds like it's "cutting more air".

Hoping I've just bent the blade and not the brushless motor shaft.

 

[Onoff]

The jury's out. Just tried with the regular nylon trim line on and wasn't uncomfortable. Rain stopped play.

I once had a girlfriend that wouldn’t agree with your wife, Those were the days!

Henrietta Hover per chance ?

Yep, the way our physics teacher explained it: if you put your hand over a pipe and then put a vacuum in the pipe, there's nothing in the pipe. You can't pull against nothing so it's the something on the outside that's pushing, not the nothing on the inside that's pulling.

Your physics teacher should have also informed you guys that it was a partial vacuum . There is no such thing as a vacuum except in some folks heads .

The cyclone is up and running again.
I had a spare tub from one of the Lidl ash collectors that were so rubbish I don't know why I bought two, but at least I had a spare.

To prevent this one imploding, I rolled a ring out of 25 x 5 flat bar and hammered into the center of the tub.
It's a tight fit so I didn't fix it in place but just welded the ends of the ring together.
I also pop rivetted a plate over the original inlet.

We will see if this is man enough for the job.

I must say it is handy having a ring roller for the few times you need it.

I 've used a thick walled ( 1/2 "old heavy black conical plastic dust bin for our sheds cleaner . Made a long radius set of arms for the router and routed out two bIn & a bit sized diameter rounds (78cm. dia ) in 15 mm ply ,got the them glued & screwed up , then put cling film over the rim of the bin and then ran a decent thick bead of silicone round the rim , set the lid on with weights and let it cure for a week before cutting the cyclones holes . Made simple blocks to fit the lid so it always locates over the lock down handles . It appears to work well . The thick wall conical shape is tremendously strong , I didn't need to make a pressure relief flap for the lid in case the depression inside got too great .

I don't think that he indulged in such pedantry. he was very much a practical person.

It did the job perfectly well, then the end snapped off when I was winding it back out of the hole. I had a bolt shear off when removing it, so I drilled and filed it out until I could start the tap, and the tap ended up unwinding the remains of the bolt thread out of the far side of the hole. I suspect I was expecting too much from it, but I had hardly any leverage on it, just a mole grip "end on", so only the width of the jaws to hold.

As usual it was made more difficult by my complete inability to drill down the centre of a bolt, so could only drill out a certain distance then had to use small round files. I had the same on a subframe, trying to remove the lower wishbones but the bolts are rusted into the sleeves in the bushes. My punch marks didn't seem bad, but when I tried to drill both the head off, I was miles away.

I was always told that a vacuum is an absolute, so there's no such think as a "partial" vacuum, it's either a vacuum or something with low pressure!

Reductio ad absurdum - there lies madness.

If there were to be a single molecule of anything within the boundary of your 'vacuum' then by your definition you no longer have a vacuum. Even though there is no measurement technique to detect that molecule - yet.

That is why we have Unleaded (no added Lead) Petrol but the Germans have BleiFrei - different legal systems.
Similarly we have Low Alcohol Beer, but they have AlkoholFrei Beer.

But we have low alcohol AND alcohol free. Low alcohol is I believe defined as below 2% proof and kids can buy it, or used to when I was a kid, whereas alcohol free by definition doesn't have any. Quite important for drivers!I was actually just jokingly replying to the point about vacuums, which is really about grammar rather than physics since you can't be partially absent, you're either here or you aren't as a rule!

 

[Farside]

since you can't be partially absent

Amputees, line up here.

which is really about grammar rather than physics since you can't be partially absent,

The misuse of "unique" as an example.

 

[Seadog]

As in 'very unique'

 

[ajlelectronics]

As in 'very unique'

Used in Photoshop Elements 10, in the menu as "Uniqueness". They didn't respond to my Enquiry about what it actually meant.

As in 'very unique'

That one boils

 

[Farside]

I am a clone I am not alone
Every fibre of my flesh and bone
Is identical to the others
Everything I say say is in the same tone
As my testtube brothers
There is no choice between us
If you had ever seen us
You'd rejoice in your uniqueness
And consider every weakness
Something special of your own
