Hi ChrisH,
I think you have it slightly wrong in blaming H&SE for all our woes, the real problem is Risk Assessment . This bit nonsense is a brilliant idea, it makes people doing the assessment paranoid, so the assessor has to think of all possible accident scenarios, no matter how slight or unlikely, in case it happens and he didn't point it out. Thus making him liable!!!
Now what are the risks involved in making and drinking a cup of Tea, and how long before such dangerous activities are all but banned by insurance costs.
My answer would be to have a Degree level in Common sense, which would prove that the holder was capable of looking after himself and his own safety. This degree would of course out-rank all spurious safety regs, and would institutionalize the concept that rules are for the guidance of wise men and the obeyance of fools.
With all this reality television about, do we think reality will ever return to real life?
Reposte, anybody??

Thread: Diamomd tool holder |

Hi Andy,
I have not had a close look at a "professionally" made tool holder, other than on You-tube so unfortunately I cannot say if they give you enough clearence but HSS is cheap enough to play around with and see what differences make
You are perfectly correct about the "near chuck experience" and if you come to Sandown MEX in December, have a look on the SMEE stand and all being well I shall have a few variations on the theme, including a dedicated screw cutting holder. I should be there to explain how you can make one, depending on what equipment you have.

Hi Jim,
I await with interest the promised article on Tangential holders, I wonder what style David proposes to show? There are also more than one style of tool sharpening jig, some easier than others!

Hi Jim,
Do you mean Tangent holders in general or the threading version?

Hi Ken,
Another convert to the cause!
I don't know anybody who, having looked closely and has the wit to understood the concept, is not taken with the idea.
I now have a special holder just for threading, it allows the thread to be cut much closer to the chuck, see previous threads for problem. I will post pictures as and when I think it can't be improved, or see it at MEX at Sandown on the SMEE stand in December.

Thread: Really useful? |
20/08/2009 19:47:33 |
Hi Meyrick,
I spent awhile making a GHT retracting threading thingy, and thought it quite useful till I reinstated my cross slide stop. If asked I would say the time spent making the CS stop is much better spent than making the retracting tool holder. Especially as it allows you to use a tangential screw cutting bit. Speaking of which I finished a special holder (mk two) for same today, when I get around to it I will try to put photos on the Diamond/Tangent thread.

Posted by chris stephens on 20/08/2009 00:12:47: Hi Meyrick,
Just two? Oh, well for me it must be a 5C spin indexer and a home made Tangential tool holder, no make that DRO on mill, or is that the GHT radius turning tool, maybe it should be an electric edge finder. As I asked "just two?" 'cos the list goes ever on.
chris stephens
PS just remembered something else that I find very useful, saddle and cross slide stops, the latter is most useful for thread cutting. I am sure to think of more, it is quite impossible to stop at 2! |

Thread: Metric vs Imperial - Practical or Traditional? |
17/08/2009 11:45:50 |
I think you should work in whatever units you like, be it Metres, Feet or Cubits. They are afterall just numbers. Anybody who calls themself an engineer, be it Pro or Am, who can't convert from one to another is quite frankly a Numptie. There are books, calculators, DROs, digi-calipers and computer programs, not to mention mental arithmetic that can be used to switch units.
Personally I use whatever unit is most convenient, anything so I don't use fractions any smaller than eighths, that is until micrometers and lathe dials read in fractions. Purists will say you should not mix Imp with Metric, well I say why not, to repeat, they are just numbers. Proviso here is of course that all units are clearly marked. Logically it is no more stupid than using Metres and Milli-Metres in the same drawing. If it is confusing to mix IMP and Metric, then Numpties will be confused by divding/multiplying by 1000 too.
The human brain likes to think in whole numbers. It sees 1" and likes it, but show it 25.4mm and it thinks "Oh dear". Show it 25mm and it is happy, but show it 0.984", "how am I going to turn to that accuracy?" Get the point?
I wish people would stop whinging about one system should be used to the exclusion of all others. It really does not matter a jot, so GROW UP.
Discuss!

Hi David,
When and how much?

What a splendid feature you have with your back issues. Any chance of going back to No1? I have most of MEW from the mid twenties on, and have been buying regularly since mid forties and I would like to see what I am missing.

Thread: Diamomd tool holder |

Hi Dave,
I must agree with you about the benefits and short comings of thread cutting. I have been making some pushbike axles from EN16T, to replace bendy Alloy ones, and get really clean cuts and threads. Downside is the ridiculous angle of the toolholder (home made) so have plans to make a special for thread cutting, just have to get my poor brain around the angles needed, unless I make one with a swiveling end! Maybe not.
Hope I can finish in time for SMEE demonstrations at Sandown MEX, unfortunately I live in a time-machine and if I am not careful and blink, I jump forward a month or two. I can't seem to find the reverse controls.
chris If this comes up twice, blame Google Chrome. |

Hi All fans of Diamond tool-holders,
For those of you how mistakenly think a Diamond/Tangential toolholder is a new or novel idea, take a look at the picture , hopefully, below. It is an image from a book dated 1886, just goes to show "there is nothing new under the Sun".
![]() chris
Clearly my hopes where dashed! How do you post images? It was one the same page as the text but did not come out on the post.

Hi David,
An excellent interpretation, do you have clearance problems on larger diametres?

Thanks for that.
Good Lord above, talk about inflation. Wonder where I put my set, they must be around here somewhere. Another of those projects that added together need more than one lifetime to finish, but I shall try. No, sorry, they are not for sale. chris

Hi David,
Out of very idle interest, how much did the castings go for?

Hi George,
If you try a Tangential tool holder you will not be disappointed. I have been demonstating my version on the SMEE stand at the last two MEX's, and feedback always seems very positive. Not only do they cut very cleanly, they are a doddle to sharpen. This last point makes them ideal for learners who have not yet learnt to grind a "normal" toolbit. Makes expensive TC indexable bits redundant, almost.
Regards
chris
