Bogs,
Some of us are VERY appreciative of your advising us about the existence of these blocks.
 
Sadly, there are those who will always argue about how many elephants can dance on a socket head.
 
If something is advertised on TV or on a web site, that brings it to our notice, and buying it is optional. Mentioning it on a thread is no different, so for crissake lets have no more discussion about alleged plugs or otherwise. I for one am p****d off with these storms in a G cup. (should be T cup, but they are not currently making them in that size).

I would just like to say that if it was not for you John, I wouldn't have known about these useful blocks. So thanks very much and don't be put off by the reaction of some folk on here.

Calm down dear Bogs, for every silly poster there are a load more people who do read and learn from others. It would be tragic if those who can't see the wood for the trees burn down the forest. Don't let them win. Stick to your guns/lathe/mill and carry on!

May I add my voice to those saying thankyou for the info about these blocks, and to ignore the nitpickers etc.
 
For myself, I have seen some useful ideas from one or other of the two John's (sorry I don't know which) and allthough I haven't progressed with them, they are stored away mentally for future use - as is this idea.
 
Regards, and please keep posting.

Hi Bogs,
I too would like to add my support for pointing out useful products. My only complaint is that you did not post the information a few days earlier so I could have added a set of these blocks to an order I placed on Monday.

Thank Christ for that, you wouldn't get many of them to a pound [ or should it be kilo ? ]

I have apparently offended several posters ... by trying to move the discussion towards Engineering.

Thanks to John Stevenson and Ketan Swali, who have both provided well-reasoned replies to my original post.

Unfortunately however; it is obvious from other respones, that I do not belong here.

Hi Bogs, please don't get put off posting ideas or new items that you have knowledge of, just because of a few who can't appreciate something that many others will find useful and even indispensable. I myself have found many of the links and ideas that you have posted very interesting and useful.

I've been in maintenance engineering for the most of my 40 years plus, working life, and I'm still learning new ways and new types of tools. Like many I may not have noticed these blocks without you bringing them to our attention, and while I have no immediate use for them, they will no doubt be some in my kit in the future. If others don't like them or criticize the design or the type of fasteners used, they don't have to buy them, do they. As a late cousin of mine always said as long as I can remember, "every day is a school day"
 
Regards Nick.

Quote 1 Good.
 
Quote 2 Thank you.
 
Quote 3 Don't let it worry you, grow a thicker skin [ very handy winters here ] and remember as the world moves on these members of the flat earth society will gradually fall off the edge.

Perhaps we all need to make more use of the smileys?
 
One person's attempt at a constructive contribution seems to be another's whinge. And that has happened six or seven times in this discussion.
 
Personally I don't give a flying ,ahem, squirrel, what people think of me, but I do care if I upset someone with my ramblings. Unfortunately the reaction to any misunderstood comment in this forum seems to be a sort of feeding frenzy, sometimes apparently carried out without taking the time to properly read the original comments.
 
Now it's possible we have all had a collective empathy bypass, but I bet if we all met face to face this would have been a light hearted and cheerful, if robust, debate on the merit of the blocks.

I suspect we are mostly gentlemen of at least middle age. PLEASE can start acting like gentlemen and leave the flame wars to the teenagers - who are so much better at that sort of thing?

This post now stretches to 4 pages!!
 
I think it is well past the time when this thread was locked and the matter put to bed.
 
Once again, thanks to John S and Ketan for the product and Bogs for bringing it to our attention in the first place.

Just a little update:

Yesterday, a customer brought up the hardness issue of the blocks to my attention. I referred this to the engineers at the production factory.

The blocks have been heat treated to HRC25-HRC28, which is at the low end of the hardening process. The engineers have taken this decision as it allows the end user to make any changes to the blocks as they so wish.

We made a mistake by referring to them as hardened, rather than toughened. This has now been rectified on our website, however, the advert which appears in MEW 184 still incorrectly states hardened.
For all customer who are ordering with effect from 23rd November 2011 over the phone, we are clarifying this point pre-sale. Our selling prices remain the same.

We apologise to all customers who have purchased this item prior to 23rd November with the understanding that they are hardened to normal “rock hard” treatment to be found with traditional 1-2-3 blocks.
In this respect, if anyone wishes to return their blocks due to this misunderstanding, we are happy to accept their return, and we will pay for return carriage costs to us.
If you wish to do this, please call us first to enable us to log and agree to the return, along with carriage costs.

We apologise for any inconvenience this may have caused effected customers.

Ketan

Thank you for the update regarding hardness.

A very civil way to conduct business.
... Well done Sir.

Hello all
 
re. comments on imperial allen cap screws:
 
Slightly off topic, but when I was a railway research engineer (before I escaped into retirement) we found that imperial allen (cap) screw heads were too small in diameter, in relation to the screw thread size, to achieve the design load capacity of the fastener, when used in components or assemblies that were not through hardened.
 
The area under the head, in contact with the clamped surface, was too small, and the compressive stress( clamp load divided by contact area) exceeded the compressive yield strength of the material forming the clamped component.
 
This resulted in deformation of the fastener seating when the correct tightening torque was applied.
 
This resulted in a loss in fastener preload, which at best allowed the fastener to loosen in service, and at worst resulted in fatigue failure of the fastener.
 
This also applied to case-hardened components.
 
We had much less trouble with metric fasteners.

Jim,

A very fair point; certainly in the context of heavy engineering.
... I will send you a personal message tonight.

Very late in the thread, but...
 
John S, What's the potential advantage/disadvantage of 1-2-4 over 1-2-3? I can see that 1-2-4 is a nice binary ratio and makes for less blocks to make a stack of a given height, but does it offer any advantages when making temporary jigs?
