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.

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
13/08/2009 12:44:30
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.

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". Looks kinda familiar, don't you think?

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?

Thread: Hart grinding rest

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.

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
