PAUL, - found this article and thought that it might interest you (if you haven't already found it).

Guess you've got new leathers by now!

Thanks, that's good to know! I just inherited a little bandsaw , have been plagued with blades running off and breaking and I've been tearing my hair out - now saving up for a new blade,

Yes, I think that most people who live in Europe would have Vandal blood in their veins! Norse, etc.too and whatever blood the rabble in the Roman armies ( from every country in the known world) would have had in their veins - Not the pure race we seem to believe we are! - eg. have a good look at the variety of shapes sizes colours etc.that there are in the UK! (not forgetting the Celtic and pre- Celtic Britons of course!) these are not necessarily recent immigrants either, they go back thousands of years.

Then we all knew that, didn't we?  

Back to drills

Thanks Rod for your reply.

I do have a TIG welder but after two years I still haven't used it ! - I decided that the price of Argon was just too much for my pensioner's wallet (also Acetelyne), To be quite honest, I don't want to store expensive Argon or Acetylene with the ever present threat of it leaking slowly and then finding that when I want to use it, it's gone!

If you use the correct tubing and follow the rules then TIG makes a very nice weld, but bronze looks great too!, whichever is best is up for debate.

Now I have changed tack and have built a small furnace in order to learn aluminium casting and have done a couple of pours. I use good old LPG gas and sometime find some good clean ally castings at the local scrapyard to melt down - all great fun I reckon! - might eventually try anodising which looks easy.

Now that we are back to drills, why is it necessary to be so meticulous about the drill size choice, and what happens when these 'expensive'? drills require sharpening? In my opinion, it would take a deft hand to sharpen them properly.

At one time, I did have a job sharpening drills for automatic lathes (for a short time as you would imagine - I got out of it after a few months) and they were expected to drill I think, minus zero, plus 002" and that took a while to become proficient at!

I did however find that the hole size could be varied quite a bit ( by just carefully touching one of the cutting edges on the stone) and managing to keep hole sizing under control.  I also found that another good way to make the drill cut on size was to round the outer corners of the cutting edges (ever so slightly) after sharpening.

These are my findings from my earlier employment experiences of course but I did find that they worked for me.

I am interested in and enjoy history too (big time) and all this does provoke thought, ie. -"what has this got to do with the price of fish?" (or drills).

There is a word which sums it all up - "Nitpicking" - get back to drills I say.

I forgot to mention Ken Sprayson who I remember as being ' the Guru' of motorcycle frame welding and his pioneering work with bronze welding, I will look forward to seeing what he has to say.

Motorcycles and aircraft used to be more or less all that I lived for and I remember being so interested in bronze welding that I spent a year or so working in a tubular steel furniture factory in order to become proficient at that "art" - and I did become that.

Also I had access to all the tube benders, saws etc. and actually built a motorcycle frame there during my lunch hours! (with normal bronze rods and using inline Vapoflux which was great, but dangerous to breathe, (It all worked fine as it turned out).

I once had a bit of an 'altercation' with an American guy who was a self proclaimed TIG expert (for aircraft frames) and I dared to suggest that bronze welding might be at least as good as TIG - I couldn't believe the indignant reaction I got - he said that I was talking rubbish and that using bronze was like sticking it together with UHU glue! - I do still feel a little uneasy about TIG welded chromoly tubing and the brittle area where the weld meets the tube, but as they say "the proof of the pudding is in the eating" and there are enough light planes flying with this type of construction!

And to think I said we shouldn't get off topic for long! - sorry about that

I like models, however I'm not a dedicated modeller myself (retired engineer), but I do admire the dedication which some guys have when making their model engines, machines etc.and I'm sure the magazine started originally to cater for these model making people.

The word 'model' to me implies that it is a showpiece, but not necessarily a 'scale model' and as such, it is very often much better than the original (mass produced) offering!

Yes, no need to be tied to a Myford, Boxford, or any other brand), they have all been good and well loved for many years, but why does our machinery have to be vintage as well? plenty of good little machines around these days. However having said that, human nature very often dictates that we go overboard trying to outdo each other with whatever machinery we might have - this can get out of hand, it all becoming a "look at me, pissing contest" and this (to me) goes against the spirit of the magazine. Surely, the magazine was started to show off people's skills and share interests rather than their purchasing power?

Sometimes we might get off track in the forum of course (off course?), to me that is ok. so long as we get back on quickly and don't go off at a tangent - it does sometimes make things more interesting.

I am extremely interested in modern machinery too, but some of us just can't manage to fit it into our budget
