Discovered today a 1491w motor running loose on the floor is suprisingly a source of less noise compared to a 90w sewing machine motor mounted to a desk.

The orchrestra rejected my 2HP instrument based on the fact it is easier to move pianos around than move that big lump.

May be a little balance to the media hysteria.

Hmmm, wasn't it a mere bird that brought down the flight in New York and resulted in a 'landing' in the Hudson?

Well, multiple strikes from10lb Canada Geese – perhaps not directly comparable.

Probably more planes brought down by collisions with gliders

Unfortunately ALL hobbies contain a "Nutter" faction whose "Rights" always seem to override everyone elses. Usually those who are paid (NOT earn) excessive wages allowing the "Hobby of the moment" to be followed until the Goldfish syndrome moves them to other "In" interests.

Hi, well today I had a bit of a spontaneous spending spree in Aldi's. Just went in to see if there was anything worth getting and spotted an angle grinder stand for 115 and 125mm angle grinders, for £12.99. The box felt reasonable heavy, so I thought why not get one and see. Moved along a bit and saw packets of grinding/cutting and flap wheel discs for £3.99 each, but they were all 125mm ones and I don't have a grinder that size, but hey next to them was a 125mm angle grinder with an integral speed regulator for £19.99. Ended up buying the grinder the stand, one pack of four flap discs and one pack of eleven thin cutting discs for a total of £40.96.

Got the stand out of the box and the most part is made of die cast, but the base is cast iron. It was simple enough to assemble, although there were no real instructions for assembly.

Just one Issue so far is that the bottom adjusting screw the keeps the grinder vertical to the work, does not make a good contact on the grinder, although it says it is suitable for their own grinder (just maybe not for this model)

As can be seen in the above photo, the bottom screw has been skewed downward as there is no positive location for the plastic pad to bear onto. Might fit my 115mm grinders OK, will have to see, but maybe will have to make a bracket of some sort to fit this one.

This stand will probably be OK for what it is intended for, but I doubt it will stand up to viigorus or heavy work.

Regards Nick.

P.S. sorry about the second photo being on its side, but it just does not want to do anything else.

Was the birthday money burning a hole in your pocket, Nick?

[Nicholas FarrParticipant @nicholasfarr14254]

Hi Neil, no birthday money, just a couple of bottles of wine and special glass to drink it out of.

Regards Nick.

[MuzzerParticipant @muzzer]

I hope you had some money left over for ear plugs and ear muffs for when you get round to powering it up! In my experience, the difference between something like this and a Makita / Bosch equivalent seems to be measured in tens of dBA.

Reminds me of the chop saw I bought a few years back. Great for cutting bar stock (away from the machine tools) but gave all the neighbourhood cats a heart attack and I had to wear my best rubber pants to use it.

We called in on the sea food festival yesterday and there was a couple of people flying some drones over the Menai straights with some pretty fancy machines.

They were flying them with a monitor on their radio control gear, good job as they took them to the other side of the straights. A few yachts were sailing up and down the straights and you could watch them on a video link from the drone.

Drones in my random album.

Hi Muzzer, I think my Peltor Optime III will be adequate, e.g. **LINK**. Don't worry I would not use such things without wearing all the PPE required.

For what its worth, I've used some industrial purpose built cut off machines with the 355mm discs, that were much "Tinnier" in comparison to this setup I have just bought.

Regards Nick.

Rod

I'm not aware of any commercial aircraft colliding with a glider, although there have been collisions between airliners and light aircraft. Those I know of have been in the US, where the rules are different. It is not unusual to see small aircraft using the same airport as large commercial aircraft.

There have been collisions between gliders and light aircraft in open airspace (Class G) in the UK. Although gliders are classified as aeroplanes, powered aircraft are supposed to give way to gliders in open airspace.

Andrew

PS: I wonder how much a drone carrying a typical Amazon delivery would weigh? Hmmmmm, a few books and it could easily be 10lbs, makes you think…………………………..at least it wouldn't be going quack, quack.

Bob,

"Steam gives way to sail" is broadly the rule in the open sea, but according to the International Regulations for the Prevention of Collisions at Sea (the "ColRegs" ) vessels which are constrained by their draught have pretty much right of way when in a channel – there's lots of water for light draught yachts, not for large merchant vessels. During congested periods such as Cowes week, Southampton harbour master sometimes deploys their own boats to try to keep the channel clear (especially around the Bramble Bank turn) but the swarms of racing & spectating yachts can be even too much for the harbour master / QHM to control.

In this case, the skipper of the yacht was found guilty of a number of offences & heavily fined.

i made the running board valances today for my 5"g Terrier 'Stepney', hacksawed out of 1/16" steel sheet. not quite finished yet

progress has been delayed by house redecoration, a new central heating system being installed, and kitchen work.

cheers,

My steplad was crew on a yacht (i.e. him and a skipper) from Grenada back to the UK. Out of the Azores they lost the auto-helm in a storm. He was able to get the rudder working by going over the side but they had to work one-on one off. In the English Channel it gave up completely and they ended up getting an oil tanker having to change course to avoid them and being brought into port by the coastguard.

I used to be a regular visitor to Manchester Airport in a light plane, approach was simple "they" left a one aircraft slot in the descent pattern and "we" joined the descent path late and from a different direction (from the side). Landed and got off the runway ASAP.

Take off was more hairy, had to wait for the jet wash to settle from the previous aircraft and then make sure we pulled aside once airborne to avoid flying into their turbulence once more.

The basic real life scenario is "if he's bigger than you then stay out of his way"

The wee boats are easy to manoeuvre and scoot round the big boats in a common sense situation

The guys we really had to watch for as navigators around coastlines and channels were the trawlers who had their gear out, sometimes they got it wrong and you had to take avoiding action

In the open ocean channel 16 could be used, and often was

Usually they would get a female crewmember to call (more chance of a reply!) then get you to confirm their position and have a chat

The worst place for trawlers was the west coast of Africa. One of our ships didn't know this and plotted a course within 15 miles of the coastline (30 miles when you knew the situation)

So they're trundling along heading south in the dark at 2am and the 2nd mate sees a wall of lights appear over the horizon and calls the old man to the bridge

The next couple of days were spent dodging half the soviet fishing fleet who were busy harvesting the unprotected African coastline of fish

That applies to many vessels, a smaller ship is a lot more manoeuvrable than say a ULCC or one of the current large box boats. When you look at some vessels specs they can take up to 5 miles + to stop and the turning circle is very very large, that said a 30,000 ton box boat I sailed on went from 0 (dead in the water) to 27kts in 2 minutes which included starting the two engines and would stop in two ship lengths (72,000 SHP). Watching the SRN4 (60kts) cross the channel on radar was always interesting.

Some will still chance their luck.

It may be worth moulding a custom-shaped pad, from Polymorph

We had some seatrain boxboats which could do 40 knots, driven by 707 pratt and whitney gas turbines

The US military paid for the fuel which was like gasoil and they had a lien over the ships in time of war to supply their needs

They burned around 200 tons a day at full whack, (an ordinary diesel ship burned around 20 tons a day)

Much to my regret, I never got to drive one

[Bob Brown 1Participant @bobbrown1]

None of the Seatrain box boats could do 40kts, and there is some debate as to what they did manage to achieve, their normal speed was 27kts at 80% power, originally they ran MGT4 when coming in and out of port and MGT7 whilst at sea (MGT = marine gas turbine) They were later converted to burn BFO (blended fuel oil) which was more like heavy marine oil but had to have an inhibitor added and had to pass through a homogeniser before being used in the engines. Also went over to a single engine while crossing the "pond" with one propeller bigger than the other. The 4 boats never did what they were intended to do. The original plan was to have 2 ships on a weekly service to the east coast of the USA from Europe and the 2 Asia boats from the west coast to Japan.

I didn't drive one as I looked after the bit that made it go like …. of a shovel.

[Gordon WParticipant @gordonw]

Nicholas Farr– re the angle grinder mounting- I have one or two like that, I got round the bad fit by turning a bigger dia. plastic pad, about twice the dia. and shaped a bit like a sucker from a toy arrow. Main thing is to check tightness often. Ultimate is to make mounting arm for dedicated grinder. PS the vice clamp doesn't usually last long, I use a G clamp, with added boot for large bits.

I noticed them referring to the gassing incident, I'd forgotten all about that.

One of the cadets on board at the time was on my course
