Where are you going to get a bit of string 10 miles long?

Worth going just to see that.

Where is James May when you need him?

Just lob the grass & leaves in a hedge--- could you really be fined for that ?. Not really "waste" in the true sense of the word , as in "old fridge" etc etc is it?

The council leave grass clippings by the road side when they cut the grass & are quite happy for their trees to shed their leaves into someones garden on a windy day. They also trim the hedges & leave the arisings in the ditch. So what is the difference?

The first part of your post is perfectly correct. However, from my experience & friendship with Jack Dash of the docks -- remember him? will demonstrate that whatever management did once they realised they had made serious mistakes they were never going to make things right. Making men stand in a field waiting to see if they had a job that day & hoping that they had bought the foreman enough drinks the night before otherwise they got sent home with no pay was no way to treat the workers. ( I lived & worked near Tilbury docks)

However, the phrase " never give a docker an even break" soon became evident when repeated attempts to raise wages, conditions & jobs for life just produced total greed from the workforce. Hardly surprising considering how they had been treated in the past.. I still remember watching the men meeting on the " docker's field" in Tilbury with the stewards on boxes calling the men to strike. Quite frightening to a young teenager.

So the solution- Felixtowe docks - Privately owned, a new setup & away from the history of the London, & to an extent Tilbury, docks.

Effectively the docks were cleared out, at great expense to the country as a result of disgustingly poor management, poor investment, poor treatment of workers & adverse union activity that spawned the likes of Jack Dash.

In a similar vein, inefficient companies eventually disappear ( well OK BT & co manage to survive but the exception proves the rule or so they say!!!!) & that is what happens & my comment, although harsh on the working man( just try going home to the wife to tell her you have no job & no prospects. ) is the reality. The whole lot gets cleared out & if the will is there it starts again with a new set up. Unfortunately the will is not always there.

I can assure you that paying those employees more money would not have produced an ounce of extra output.

To do that you would have had to sack the lot clear them all out & start again.

If they cut it the wrong size , why exactly does one accept it ?

Why not hand it back & say "  not what I asked for "-- End of !!

You do not state the box size but I have just made a couple of 2ft square boxes 6 inches deep.

I made the 6 inch sides from 20 mm planed softwood which i grooved 3.5mm 5 mm in from each edge.

I assembled the softwood as a frame pinned & glued at the corners with the base in 3mm ply set in the grooves & glued which not only reinforced the box held it nice & square. One of the 4 sides was reduced to just below the groove on the upper edge & the lid was made as a sliding piece of 3mm ply, The piece cut off the one side was fitted to the edge of the ply to act as a finger pull & maintain the look of the box.

Over the years we made quite a few smaller boxes like this as it is so easy & quick. You can make it deeper if you use ply for the sides & if the base is grooved into the sides it will hold it together Ok.You do not need thick ply for the lid & base if the box contents are not heavy. You can hinge the lid but if grooving for the base then the same set up means you can do it all in one go & you do not have the hassle of fitting hinges & making a catch etc

Is that the regs where you have to lob them in the hedge & b..ger off quick, when no one is looking because the local council will not take them

The pin of the key should fit the holes fairly tightly to prevent "key rock" & the teeth should engage the teeth of the chuck correctly with the key at 90 degrees to the chuck. I have a dozen chuck keys collected over the years & all have a variety of gear diameters & pin sizes.. Some for chucks of the same capacity

The key in the picture is clearly wrong for the chuck

May I suggest that the user takes the chuck to a decent tool supplier & gets a chuck key to fit the chuck & his experience will improve no end.

I would also wonder if the term "Jacobs chuck" is a bit like " Hoover" & is being used to describe some inferior chucks which may distort the debate somewhat

Going slightly off the subject of your bottles. But still on gas bottles .

Our local scrap yard cuts in half the BOC acetylene bottles. Welds on 2 handles & flogs them as post  rammers.

I bought one without handles & have sliced off 3 - 3/4" lengths 5.5"  diam for rims for the front wheels & flywheel of my traction engine. They have 1/4" thick walls & I have enough for another 10 .- cost me a tenner.

Re calor gas bottles I have a small one ready to cut up, once i get the remaining gas out, & will cut it to give the rims for my rear wheels ( 10" diam).

So after 47 posts( plus a few on another thread) I cannot really see that the forum has come up with an indisputable answer

the question being that the operator rotates a ring with a key. Whether it makes a difference if you rotate that ring from one hole or all 3 is what i wanted to know & why.

Personally I do not think it needs all 3 & nobody has convinced me otherwise yet. Other than saying ( typically) " somebody told me to do it"-- & several have said that so far, among some other theories based on concentricity of the ring

& with the greatest of respect to all those that have taken the time & interest to reply, that is not really proof, is it?

But you have to admit it does create a lot if discussion & when i asked it years ago in my works canteen we came to the decision that the practice really boils down to personal preference--

and why not? if that is the way you want to do it, then do it

But thanks for the comments all the same

I may stand to be corrected here & you my be perfectly right, but grease does not go "Thin" when hot. So I would suggest that if grease is being expelled it is initially due to too much in the bearing. This is what is making the bearing hot which cannot be good for the bearing if over expansion occurs. Agreed some bearings may be designed to run at a certain high temperature.

Re " runny" grease I wanted some " thin " grease so I put some high speed machine grease from one of my moulding machines ( forget the grade) on a tin lid & held it over a blow lamp. Nothing changed as far as the grease was concerned. It certainly did not thin out. This is not conclusive of course but does suggest that general machine grease would stay at a consistent consistency

My theory for three holes is this

Lots of drills have a turned down shank to half inch. If the jacobs chuck had one hole & a workshop was using lots of these drills the teeth of the chuck could become strained & I have seen chucks with snapped teeth. With 3 holes the law of averages suggests that over time the teeth get used fairly evenly.

Which has nothing to do with why one would need to use the 3 holes each time one tightened the chuck but would extend wear on the teeth themselves

As a comment/query

I always thought that one should not put too much grease in bearings as it created heat.

Is that correct?

If one looks at sealed bearings there is very little grease in the bearing

Geuine query

Are they?.

I see them on some you tube vids such as Myford boy & I never have any luck with them so wondered why people bother with them

( & no -I will not ask if one grips it in 3 places )

I cannot see that . The chuck with 3 holes is not going to have the same hole used every time. Therefore, if distortion did occur it would be compensated when a different hole was used the next time an object was placed in the chuck. Over its life there is a fair chance that every hole will be use roughly the same number of times unless it is in a drill press that always stops at the same place. So using one hole to tighten would not cause long term distortion of a jacobs chuck -- would it?
