Thanks for that ‘dip-check’ Bill

I haven’t used RS for a while, but I’m still on their eMailing list … hence received the ‘News’ that they were stocking these Wera tools [incidentally, my apologies for last evening’s typo. ]

Frankly, I had never considered Wera to be newsworthy; so curiosity drew me to click the link.

My initial surprise at the price-point was what prompted my question to this forum.

I did a Google search for “the modelling hub”

Seems like it is quite a popular choice of catch-phrase [or whatever the correct terminology might be]

MichaelG.

So … the [nearly] consensus opinion seems to be that they are what I always thought them to be … ’good’ mid-range tools

But RS and/or Werra are trying it on, and trying to take them up-market

Best I can do is these rather low-res scans, converted to .jpg

Hope you can get what you need from them

No, Nick … I am aware of the price of Snap-on tools, and of their quality

I was simply surprised that what I had previously thought of as ‘good’ mid-range tools were those prices, and asked if they were that good,

No value-judgement on my part … quite the contrary … it was a straight question.

I have always understood Wera tools to be ‘good’ but an eMail from RS this morning links to some surprisingly pricey items: **LINK**

Are they that good

That’s a bit heavy-going for my caffeine-depleted head, at 06:30 Chris

But I think I have two relevant comments:

1. You wrote ‘The head and all in it can be cranked up or down in a fixed(Shimmed) vertical plane-Z1’ … but Z1 is an axis, not a plane, and it’s generally better to keep your terminology consistent.
2. It appears that you are presuming that Z1 and Z2 are perfectly aligned in manufacture … but although ‘very desirable’ this [in the real world] is not inevitable.

Please excuse me if I have missed some subtlety in your phrasing.

I have never felt inclined to join Scribd … but here it is: **LINK**

Thanks again, Howard … I am happy to accept the spirit of what you wrote

I had no intention of nit-picking … just part of my ongoing quest for understanding.

Many, many variables in carbon-fibre composites !!

This is probably the most pertinent paper I have seen: **LINK**

Dave,

The two lowest frequencies of a pendulum rod must surely [?] be its first bending mode and its first torsional mode … everything else, I posit, will have a higher frequency.

The magnitude and frequency of both of these will depend upon the construction details of Jo’s pendulum [and they should be simple for him to measure] … but I would expect both to be many octaves above the frequencies he is observing.

… hence my clutching at the ‘beat frequency’ straw.

Thanks for your candid response, Howard … I was probably reading too much into your statement that the wire carried no current.

Quite so … but many of the others major on the word billet

I’m not going to labour this … I just asked a question and have had a variety of answers.

That will suffice for me, thanks.

MichaelG.

For your delectation and delight, David

Looks good, David

You have basically re-invented a device which was available for ‘ornamental turning’ lathes
