Thread: Making your own case hardening compound.
21/03/2012 11:16:47

Richard, I don't know if Kasenit (I still have enough for several lifetimes) contains Bariun Carbonate. But what I know is that G. Lautard recommanded it in his recipe for pack case hardening. As carbon he told to make it from walnut shells and plum/abricot/cherry stones.

Many years ago I tried to get it, but our administration chemist denied me the permission (although it is in a poison category which is not very high and I had - theoretically - the right to get it)

Seems times have changed a bit; a couple of weeks ago I discovered that now I could order it online and no-question-asked from a supplier for the ceramic hobbyists. It is used for some glazings. Rather cheap also, iirc. If soneone wants to know more, I can post the link to the (German) catalogue.

Thread: Which boring head should I go for?
20/03/2012 22:10:44

... and bought a Far Eastern 2" boring head. They appear to be the same whatever badge is on them. BIG mistake.

I must say I like the look of Graham's boring/facing head!

Dave, I can only endorse that. I have also one of these 2" boring heads and never could make a decent cut with it. I tried several types of tools, long or short, thicker or slender, Carbide and HSS, all to no avail. The surface always looks like cut with a cold chisel. But I cannot detect any play in the head; the slide is not loose also. I can only think that the Morse 2 shaft is not man enough.

That said. I built the GHT boring head way back 1980 I believe, and this one works like a charm in the same machine. But sometimes I could use one a number bigger. I was thinking about making the GHT somewhat larger (120 - 130%) but now our dear colleague Graham has his design (with facing capability) published in that other mag... I am very tempted!!!

Thread: strange metal
17/03/2012 20:08:50

Yes John, I also had shafts which could be machined quite easily. When I wrote 'has to be hard' then I meant the outside. I did not mean that the bars are hard up to the center like e.g. a piece of round HSS. Possibly there are different types of that stuff. One type I remember was wrapped, or rather shrunk in a thick blue plastic 'skin' with a Swedish type description. A product from Uddeholm perhaps?

Thread: strange metal
16/03/2012 13:25:49

And WHEN it is hydraulic ram or other (hard)chromed stuff, then it does mot machine beautifully! I had to throw away a couple of these nice rods. Only an angle grinder would scratch the outside. If you consider the usage, it has to be hard!!!

Sometimes the core part is softer, as it would be if case hardened before chroming.

I thoroughly enjoyed reading your article in MEW 188,

Me too, as some people use to say. Except that I - even after reading the article 3 times - still do not understand it. But I know that my brain is not now as it was 50 years ago.

However, when you have a DTI and want to move a quill without depending on the scales, why not use it directly to measure the movement?

Well, I am sure someone will show me very soon where I am wrong (or daft wink ).

Btw, issue 188 arrived in Switzerland Saturday 10th of March. Speedy, isn't it? faster than for the natives it seems.

Thread: What type of end mill
09/03/2012 10:50:20
Posted by JasonB on 09/03/2012 07:38:13:

Have a read of this post by Bogs, it gives a good description of removing the majority of the metal and then skimming the final few thou.

So even to a capacity like Mr. Bogs is not free of doing stupid mistakes - and nobody seems to notice it. Ok I did not read all comments...

In the first 2 pictures he numbered the 4 sides of the bar (going clockwise) 1-2-4-3.

But in the next pic it suddenly is 1-3-4-2.

Quite confusing for a newbie, methinks...wink when the description tells which side has to be at which position.

Thread: 3 phase motor rotation direction
02/03/2012 23:01:05

Reading the posts above, I can agree with the arguments of both sides (although it would be interesting to know what kind of error in an installation can lead to a fire after working ok for months or years).

However, the mention of "qualified electrician" brought up in memory a post from a colleague in another forum; I hope he will not be offended when I quote here his message verbatim. Read and enjoy!

>>

Just had an interesting discussion with a Paraguayan electrician. I was commenting to him that I was re-wiring a house, and had been dismayed to find in many parts circuits consisting of a 4 square milimetre live cable, and a 2.5 sqmm neutral. His reply (translated) : "But that is normal, because after coming out of the aparatus the electricity has done work, so it is weaker and only need a smaller cable." Hope you enjoy this one as much as I did; and think that this is what he teaches to his apprentice... << "qualified" has not the same meaning everywhere...! Greetings, Hansrudolf

You write in Your message “I was most disturbed to se Dias Costa's "two simple testes" - I thinke hes talking bo%&*$^&£.... no signal “.

Hi Dias,

I think Neil's remark was about the text you choosed for your test. I liked it wink

But why the heck did you write twice 'posted from MS Word 2003' ?

Well this is a test for the new editor also. At least quoting is working again so that I can write on the left margin without the quote bar (but I needed a couple of trials to get here).

Hi Dave C,

wonder how you managed to put a 1.5" bar in an ER32 collet chuck. My ER32 set only goes to 20 mm.

(also just a test for the so-called new editor, I see no differences...)

Thread: Announcement from Arc Euro Trade Ltd.
10/02/2012 22:34:49

Mr. Swali, why not set up a laptop at the exhibitions and help the not-so-computer-literate visitors to enter their orders on the place? Doing that your stock counters would always stay correct.

Mind you, I never will have the opportunity to check this out. I could say it's not my business...

Thread: cutting polycarbonate disc

Strange that one has to wade through 6 mostly off-topic answers for finding the only sensible one.

Btw, polycarbonate is neither perspex nor alu.

Thread: Drilling brass - seizing

Thank you one and all for your advice. Sorry I have not come back in before now. Redecorating and grandchild.
The hex bar I used was found in a yard years ago so no idea what it is. It does come off in small chips and screams as it goes, and to me, dos'nt seem as dark ? coppery as bronze or gunmetal.

[end quote] - cannot go back to the normal entry position in this d*"% editor.

Anyway - small chips, screaming, work hardening and a yellow colour almost like ordinary brass - I would bet that this is aluminium bronze then.

(I liked the line "redecorating and grandchild" - hope you did not the firstr to the second )

Thread: Milling - what do i need
01/02/2012 11:35:22

After seeing that someone complained - rightfully - about someone writing in another thread "course's" instead of "courses", may I take the same line and ask if Mr. Hall really uses "it's" 3 times in one sentence instead of "its"???

> It's popularity is, I feel due to it's apparent ease of use, a situation that leads to it's use > when other methods would better meet the requirements

Sorry for my complicated phrasing; writing simple is more difficult (for me) than putting the finger on blatant grammatical errors

Thread: think tank
27/01/2012 23:56:20

A 'better' idea (well... )

Many years ago ME had cartoons of the famous 'Chuck the muddle engineer'. Always something to chuckle.

How about a column with some of the immortal literary pearls we often see here.

E.G, as seen lately:

Q: ...I broke 2 taps...the holes are through, not blind...

A: Before I begin, are your holes 'through' or 'blind'...?

Hmm, I wonder what the subtle differences are between

- clalipers

- claipers

- clipers and

- calipers.

I only own the last type I believe, but I'm sure Wolfie would like to know also

Thread: Image size
24/01/2012 22:20:25

There are lots of (free) picture resizers around. For XP I use one which only needs a right-click on the picture, abd the resize order shows up in the context menu. A short Google search gave the impression that what I have works only on XP, but for 'more modern' (phew!) Windows versions there is e.g. this one:

http://imageresizer.codeplex.com/

It is quite pointless to upload large files over slow connections and leave the resizing task at the receiver's end.

Thread: Facing a casting in the lathe
23/01/2012 10:26:20

Peter (and Jason too I think), you seem to mistake lefthand and righthand lathe tools.

Assume the tool is mounted 90 deg. to the lathe bed, a righthand tool cuts from right to left, and a lefthand tool from left to right. If you don't believe that, look how the shanks for carbide inserts are designated (e.g. SCLCR versus SCLCL).

That said, a lefthand tool mounted parallel to the bed is ok for facing towards the center, but round-nosed tools work a treat also.

John, I have many pictures of screwcutting gearboxes, but to better understand your disappointment, do you happen to have a picture of Judy Williams somewhere, which you could post here?
