I would urge to not to drill it or use an impact wrench unless you know for an absolute certainty that it is a screw, other wise you may wreck the shaft. Please, contact one of the spiral cutter suppliers. Their product will have exactly the same arrangement, and so they will be able to tell you...

Which is why the Holocene is not a good example of anything. In geological timescales it is the blink of an eye, and a very untypical one at that. Move the silly timeline you keep posting back a few million years and you get a very different picture, with temperatures yo yoing up and down by far...

If it turns out to be an interference fit then personally I wouldn't bother trying to get it off yourself. Take it to a local car repair shop. They will have a variety of pullers, and probably a press. To buy something suitable yourself is going to cost far more than a replacement pulley and, if...

And as I have said, the manufacturer of the spiral replacements will know this. They don't come with a pulley, so presumably intend you to use the existing one. They will therefore be able to tell you how it is secured.

Or it could be there to facilitate some task to do with the manufacturing of it in the first place.

But Jacob surely one has to ask, why seek the opinion of the electorate if there was no intention to act upon it? Or put the boot on the other foot. Had the result been in favour of remain, would you have been happy for it to be ignored? No, I am quite certain that in those circumstances you...

Anyone who participates in these threads should know that Jacob's opinions on the subject of bias should be taken very seriously. He has far greater expertise in this field than anyone else on the forum.

So what is the alternative? Should you, or perhaps Jacob, be allowed to vet the result of any democratic election or referendum, and overturn any you don't like. If that is the case why bother. Elections will often lead to outcomes that be seen as daft. Look at the US and Trump, arguably a big...

One thing you could try is to contact any of the firms who do a replacement spiral cutter block for this machine. They will be able to tell you if it is supposed to have a thread in the end of the shaft. Not sure what it would be for on your machine, very much doubt it would be for holding the...

Now resolved with help from another Harrison lathes group member. He even got the price down by throwing in an offer ! So all good thanks. Still unclear why many sellers will happily use e bays global shipping programme, others flatly refuse. I have asked those who refuse what the reason is, yet...

I doubt there is any great difference between this and my 636, so I think the pulley will be an interference fit on the shaft. The problem I had was that the shaft is not that big. Having applied a few tons of pressure on a press without it showing any sign of movement I was concerned about...

I previously had a kind member on the Harrison Lathes group do this for me in similar circumstances. So have put out a request there too.

Are you sure it is a screw, and not simply a hex in the end of the shaft. On the 636 there is an M6 hex head bolt and washer, but not on later ones. The pulley itself is an interference fit, and will be fun to remove without damaging it. I have all sorts of pullers and presses and ended up...

I am an avid collector of American pocket watches and have an interest in one currently on e bay. The seller is in the USA, and is one of many who will not ship abroad. I was hoping a member who lives there might be willing to buy it for me and ship it over to the UK. I would of course transfer...

I use their very small fraction of a mm drills for watchmaking. They always cut well but seem to have a bit more give in them than others, so don't break as readily.

Charming idea, and beautifully done. Hope things are looking up.

Ice, ICE ?? You bounder :)

You could try Philpots hard chrome in Luton. Famous in the motorcycle world for refurbishing fork tubes. They did my old Myford 4 spindle. Hard chromed, not to be confused with the purely decorative variety, then precision ground and the bushes etc lined bored to suit. Cost me £200, but quite a...

I had an issue with a Samsung washing machine where several of the commutator segments popped and stood proud, causing very rapid wear of the brushes. Apparently due to them switching to a more eco friendly glue in the construction, which turned out not to last very long! Got a free replacement...

Basic lack of imagination. What could possibly go wrong being the important question, then look at how best to avoid it.
