This sort of thing from Chronos

Very many thanks for your prompt, helpful and courteous response.

That's exactly the sort of thing that I had in mind – but would need it either with parallel shank or R8 taper.

Is that sort of design reliable and robust?

With best wishes and thanks again.

And if your buttock clenches hard enough ega – it will tend to pop even a tight fitting plug!

This came to mind when I was reading about penguins' ability to project their faeces so as to avoid having to leave the nest; according to the article in The Week the research "team also calculated the “rectal pressure” required for such ejections, and found it to be 28 kilopascals".

The advice is to take care if you pick up a penguin.

"To key or not to key" pops up regularly on here.

The instruction that we were given as Apprentices was "NEVER"

The proof of that is as I walked past another Apprentice using a Slitting saw, there was a sound like breaking glass, and bits started flying around the shop!

Fortunately for me, I didn't stop any of them.

He had used a key, and the saw had jammed.

Without a key, a jammed saw will slip.

With a key, the key will split the saw, leading, possibly to injury or damage.

Having a left hand thread, you could mount the saw the other way up and reverse the spindle. That would tighten the clamp nut. But DON'T use a key if you value your health.

MC B, the stepped ones work OK if reasonable quality though I think there have been some poor ones about in the past which has given them a bad name. Looks like a couple of the likely suppliers are out of stock of the R8 which is probably why Chronos are not listing that option at the moment

I apologise for NOT starting a new thread with this specific issue.

I have now discovered: link from Ebay

It seems to me that having and using R8 rather than parallel shank will add rigidity?

Chronos is (fairly) local to me so I have visited and purchased quite a lot from there before Covid-19 pandemic lockdown.

Very many thanks to everybody for their comments and suggestions

Yes, I bought one several years back and it was absolute rubbish. The stepped circles were far from concentric. I stick to single size ones now.

I have one of those stepped arbors and agree with Russel. They also allow only very shallow depth cuts (not depth of cut!) i.e. there's not a lot of room between the top of the blade and the quill.
