Hello Tony,

Welcome aboard.

This is a wonderful site with an astounding amount of friendly advice and knowledge available.

Good reading and inspirational.

I also enjoy my machines, possibly more than actually producing anything.

Cheers

Hello All,

I feel a complete dunce; but could somebody explain to me how to adjust an adjustable reamer ?

Playing with the nuts at either end doesn't seem to have any effect, other than trying to twist the blades.

Any help would be greatly appreciated.

Daniel

I am also more a Reader than a Writer, but I cannot help feeling that this thread has more than a coincidental relationship with the "how to lose friends ..." thread.

Thank's C.

Hello All,

I came across this thread while browsing the dusty recesses of the site.

I thought it deserved bumping back up, for those who may not have seen it.

I haven't laughed so much in ages.

Does anyone know where any other articles by this author are to be found ?

Roughly where are you in Africa, John ?

Mark - summing up my sentiments right now

John - (sorry for referring to you as David, earlier), It was while trying to make Mr Pete 222's Wobbler engine, that the problem came to light. He kept emphasising the importance of the perpendicularity between the cylinder block and it's pivot pin. Upon screwing in the pivot pin, even with all the optimistic enthusiasm I could muster, the thing was anything but perpendicular. I would guess a good 10° off.

The point regarding appropriate accuracy is one I subscribe too also. However, in this example, it would have been an abuse of the word, to have used it in relation to what I had just produced.

Martin - Yes, my problem was to get a vertical (ish), hole. However, with all the input from the others, I would guess that achieving a hole of any predefined angle would yield similar, albeit random, results.

Nick,

I completely agree with your comment on sourcing.

I'm in Central France, so naming the supplier serves no purpose, suffice to say that they are a local industrial supplier who would not get away with supplying sub standard goods. I expect, in truth, the drills will not be the very best available, but of a servicable quality.

In view of the level I'm at right now, it's probably best to stick with those. They're relatively cheap to replace.

Regards, Daniel

Hello all,

Thank you all so much for such a wealth of good advice and very helpful opinions; really appreciated.

The XY table was summarily dismissed from duty, at dawn, this morning.

Now, please don't shout at me, but I took the table off and gave it a facing job in the lathe. It was certainly not flat. I don't expect any miracles from the excercise, but at least I have a flat surface on which to place the square.

David - I have also had this drill for about 20 years. It's not badged Rexon, but may well be from the same source. Until now it has served me fine but, moving onto finer work, perhaps I've suddenly found it's limitations.

I will certainly fabricate a screw jack to go under the table ( I hadn't considered deflection issues).

Agreed, also, that precise drilling may well be best executed in the lathe; I'm getting along nicely with the 4 jaw chuck.

Also, I take the point about over zealous clamping. Sometimes we fall into rigid trains of thought, and it's good to be brought out of them from time to time. Roy Underhill school .

Will drill some test pieces this evening.

Thank you all once again.

Some photos of the scene;

Thank's everyone for such quick feedback.

Plenty of food for thought. Mainly find myself reassessing the "reasonableness" of the drill press itself.

I will carry out the various checks as suggested.

It was only a 3.5 mm hole and was clamped in a vice (same source as the drill ).

The drills themselves are from a reputable source.

Hello,

I am having awful trouble achieving a reasonably perpendicular hole, through any real depth.

Forgetting round stock for the moment; I had the same problem, this afternoon, on a piece of rectangular aluminium (25 mm depth).

Does anyone have any pointers on this ?

I would say I have a reasonable drill press, with sharp bits.

Hope someone can help;

regards

Don't know if we're talking about the same magazine, but my sentiments echo yours. Maybe there's only so much that can be written on one subject ?

Hi Nick,

I recently bought a lathe from Warco, which I had them fit a 2 axis DRO.

Very pleased with the result, but would think careful reflection on the positioning

of the scales would be in order. Not obscuring any axis locks or oilers for example.

Electrically it would be a no brainer as it's pretty much prewired.

Good luck and enjoy the machine

Thank's for the welcome (s),

I'm a British expatriate, living in central France, near Limoges.

So far my engineering has been restricted to demand driven projects;

but, time permitting, would dearly like to develop the model making skills.

My main passion is with all things steam.

Greetings to the forum.

I've been lurking here for a long time; now taken the plunge to join, so hopefully can add my tuppence worth and glean some of the abundant advice.

I'm not new to engineering, per se, but still seem to learn heaps every day.
