Bogs,
I actually agree with you, and believe that some of the old ideas may actually be better than new ones, purely because the old ideas will have stood the test of time. But in my case, I have learnt over the years that I simply don't make the connection. It's not that I'm lazy, or that I'm thick, but that I just don't see it. It's happened so many times in the past that I've missed the blindingly obvious. Let me give you an example from my career.
In the early '70's I taught myself how to design reasonably simple transistorised switching circuits from a pair of books. I became reasonably good at circuit design. Part of this design always covered the possibility of inter-electrode leakage - the so-called Icbo leakage. As a result my circuits never failed due to that problem. Fast forward a few years and we had a number of pieces of equipment assembled by a local firm, the agreement being that I would get those that failed, to work properly. Apart from the usual ic's wrongly inserted, there some that failed due to Icbo leakage. It took three or four of these failures before I twigged what was going wrong, and yet I knew all about the problem. You see I had never experienced the problem in real life and so couldn't make the immediate connection. The end result was an immediate modification to the circuit to overcome the problem.
And a more immediate problem. Yesterday I was repeating the "leveling" of my lathe using the hefty bar stuck in the 4-jaw chuck, two turned barrels, and measure followed by tweaking the tailstock end bed support posts. I had three or four attempts to get it to less than 0.02mm difference, each time tweaking the relevant support up and up and up - in fact I failed. Sitting and looking at it, I then stuck the clock on the bar, and pushed the bar. And got an immediate large movement. Changed to the large 4-jaw chuck and found an immediate improvement in stiffness. Problem solved, but at the expense of having to do it all again to get back to where it should be. I got there in the end, but have never come across this problem of flexing before, although I was aware that all things flex to some extent. Hence I did not make the immediate connection, instead carrying on tweaking the support.
Still, it's all grist for the mill. And I'm learning all the time.

Hello and welcome to our forum.
I have read your posts and let me say I think you possess the necessary skills to quickly grasp the essence of our world, machining, building, constructing is a syntactical process, the machine will speak, the drawing speaks, and yet you are speaking just by interacting by what you have done. Math is the language of the universe and I safely assume you have that knowledge , so all skills are in place, please keep us informed on your projects however insignificant you think they maybe,people on here freely give their experiences and knowledge willingly with the sole purpose to share.
God bless Anthony.

Arn't we all?
Usually in this order if you're like me...... ? :dremel: :doh: :coffee: :smart: :dremel: :thumbup: :nrocks:

Right, here we go, Question No.1
How do I insert photos?
I can see the Insert Image icon above but...
I have Paint Shop Pro so can easily load from the camera into PSP, resize, and save in a variety of formats so no problems there. (I can even produce photos that never happened as my son & daughter in law found out when I managed to merge two photos to get one of them both looking forward simultaneously, so no problem with modding photos.) But how can I upload from my computer and presumably place inbetween these commands?
Also, (I suppose this is Question 2) is this the right place to ask this question? Should be in, eg, the How Do I section?

Peter,
Answer to question 1....
http://madmodder.net/index.php?topic=607.0
And 2....
Questions are answered usually wherever they are found :thumbup:
If you look at the home page most topics they tell you what they are for and what kind of stuff to post there. But if it's pic' related then usually the "gallery" or the "Project logs" sections get all that type of question.
But.... Better you ask here than not at all :thumbup:
Ralph.
