Thread: Colchester Bantam metric scewcutting on imperial only machine
26/07/2012 13:27:48

Hello all Mathematicians,

I have an interesting little lathe of Swiss origin, with the following details:

- no thread gearbox

- set of gears: 25 - 100 in steps of 5; 120, 127

- IMPERIAL leadscrew, 8 TPI

- only one intermediate gear stud between tumbler and leadscrew.

The setup for fine feed is: 25 - 120/30 - 127

For all metric threads the 127 stays on the leadscrew.

The table shows 19 metric pitches from 0.25 to 3.5 mm

Just a few examples:

Pitch 0.5 mm: 40 - 100/50 - 127

Pitch 1 mm: 40 - - - 127

Pitch 1.5 mm: 60 -- - 127

Pitch 2 mm: 70 - 35 /40 - 127

Pitch 3 mm: 70 - 35/60 - 127

I leave it to you to calculate errors; on the ones I checked my electronic gadget showed numbers like x.9999999

If there is interest, I can show gear combinations for the other 14 pitches too...

Greetings, Hansrudolf

Thread: Grinding lathe tools
16/07/2012 22:27:35

If you want SHARP HSS (and inserts also) tools, there is nothing better than one of the small Diamond wheels from Eternal Tools:

**LINK**

I use the very fine D9 grit. This is only suitable for giving the razor sharp, shiny edge. For removing material a much coarser grain is necessary. I have the toolrest set to 6-7 deg. (clearance) most of the time. I make the wheel moist and clean it (often!) with a brown Scotchbrite and soap. Maybe not what E.tools write, but it works for me. This fine wheel, although not really cheap, lasts indefinitely.

I use this wheel in a (kind of) old T+C grinder, but it could easily be done in the lathe (couple of newspaper over the ways if you use water). Or cobble something together, Worden-like, with a small motor.

Just a satisfied customer...

Thanks Michael and Andrew, all clear now (more or less). I'm no CNC machinist,unfortunately frown

Hi all,

Whenever I see one of these probes like the one in Phil's link I wonder for what purpose can the vertical movement of the probe be used? Complicated sentence, but I can't formulate it better. Although I see that in the horizontal plane the instrument works as a (bulky) edge finder, I see no sense in touching a workpiece from above. Don't tell me you know then how far away the spindle is from the work, there is no absolute reference and the milling cutter does not stick out exactly the same distance as the probe ball. So I'm lost what one can do with that instrument.

Thread: MEW index interfaces application
28/06/2012 23:25:12

Hi Dias,

firstly: thanks for all the work you put into this.

Now where the ME index runs ok on my system, both the MEW and the E..(psst!!) index start with a Windows error: No Data Media (my translation; I see the German text). There is an exception code given, which I cannot paste here and don't want to re-write it unless really necessary.

When clicking 'continue' or 'abort' (several times) the program then starts correctly it seems.

Have others also this problem? Can you do something about that?

Many thanks, Hansrudolf

Terry, I can't help you with a supplier, but what you need is an Aluminium alloy from the Al-Cu-Mg group, with around 4 % Copper. Other brand names are Avional, Aludur. For more informations consult Wikipedia.

The table under DIN 1725 gives the appropriate W-numbers, if these can help you...

Thread: This site and Opera.
12/06/2012 22:18:10

Very strange, Wheeltapper! I use Opera almost exclusively and have no troubles whatsoever. I only use Firefox for online banking, because (some years ago) Opera had troubles accessing my bank, and now I didn't check it with the newer versions. Opera updates sometimes without asking permission, what I detest, but you cannot have all. Now it's v. 11.64 here too.

I much prefer Opera's page layout to any other browser I tried. To be honest,hiding the bookmarks (some versions ago) was not to my liking. Also organizing them is a hassle, but I rarely have to use this 'feature'.

Greetings, Hansrudolf

P.S. written in Opera...

Thanks gents, the 'right click' and 'open picture' works also in Opera.

Is there a chance (in England I suppose) for this car to get the legal papers and licence to run on public streets? Here - no chances for that I think.

Bigger pictures please, Ramon! Or such that we can enlarge them (although I don't know what enables this, but others could do it).

Thread: The potable engine

This really hard drink was discovered in ME 4431, page 770. Announced even in very large letters, so it must be something good. wink

May be a bit harsh in your throat, but could be usable to flush down fish 'n' chips or haggis!

Having read all of the comments on this thread but particularly those from DC I will attempt to unusbscribe from ME. I will be saddened to do this since I have about 50 years of ME in the library but I am less than happy about the way that it is going.

Bye.

I am very seriously contemplating this too - in spite of my collection going back to 1925. More and more I got the feeling that MHS is run by a bunch of tw!zz. Has anybody else also noticed that DC's writing style in his editorials is completely different to his style here? Maybe he exists in several incarnations???

I agree... crying

To my excuse: not knowing this instrument, I thought the shiny surface was from the part which has to be marked.

You should be able to file or mill that true.

If I'm not completely off my shoes, this would rather need the mysterious putting-on tool than milling something off (and making the error even larger).

But who knows, maybe I am...

Thread: Not sure if it is me or not!!1

Hmm, can someone tell me what 'compatibility mode' in IE does, so I can ecentually find a similar mode in Opera and Firefox (that's what I use here, sorry no m$oft sw frown.)

Thread: Link system broken???
14/05/2012 12:49:24

I see in several threads that people are trying to insert a link, but instead get a blue **LINK** label which returns to a blind end in the forum.

Until this is fixed I propose that all links are given directly (http://...) and not via this silly 'superimposing a link over any arbitrary word'.

If the link is too long (longer than one line in this editor I think), use TinyUrl please!

Thread: Manual for Realm-Royal 10" shaper

Cannot help you with this John, but may I ask you politely what you expect to find in a shaper's manual what you cannot learn from having a sharp look at it?

I own a Boxford 8" and use it without any kind of manual.wink

Thread: What lathe to get?
13/04/2012 22:17:47

Mark Foster, would you please be so kind and upload a couple of pictures of your Leinen lathe?

I wonder if you have the same as mine.

Don't hurry with this btw, but it would be nice.

Congratulations Nobby, it's my birthday too!!

I made myself a present of the ER32 indexing blocks (aka Stevenson Blocks) from ARC. Very nice piece of equipment....

Good work with your copy system; think I have to remember this when the need arises.

Thread: Which boring head should I go for?
21/03/2012 21:38:55
Posted by Graham Meek on 21/03/2012 12:40:26:

Hello Hansrudolf,

Glad you like my design, my aplologies for writing for the other mag.

The boring head problems that you are having, is the milling machine gear driven or belt driven?

Thanks Graham, no apologies, I begin to like the 'other' more and more. For me there are much more interesting articles than in ME, and I get always a bit annoyed when I see errors in almost every MEW. (I suppose DC will try to choke me for that if I were nearer wink )

The machine is a Fehlmann Picomax with variable drive via movable pulleys Much too good for me actually! 3ph as most of my machines; today 3ph current is in every house here.

I have also an Emco; the head only to be exact, mounted on a much heavier table. This was my first milling machine. I am a bit ashamed to confess I don't use it much now, expecially when I see the wonderful work you do on it. I am totally spoiled from my other machines. And it loses oil from the spindle; always a mess on the table.

Btw the GHT head I built on the Emco, and it works perfectly also on this machine. The larger head I did not try on it, I suspect it would show the same problem or even worse.

Greetings, Hansrudolf
