Thread: Conversion Chart
25/03/2013 14:31:23

Sorry about that, I thought I'd set public sharing, but apparently it wasn't accepted. It should be OK now.

If anybody is interested, some years ago I constructed a conversion chart for members of my ME club. It's in the form of a 2-page PDF that can be downloaded from...

http://kvisit.com/S4IvyAg

The tapping drill sizes were calculated with a 65% engagement for diameters up to about 3/8" or 9.5mm, and 75% for larger.

You can print it any size you like - I keep laminated A6 double sided versions near my computer desk and in the workshop.

I'm using Firefox 18.0.2 under Win 64 and on some forum postings the adverts down the right hand side overwrite the text. See below for an example.

I've just noticed a series of complaints from last April about this very problem. A year is far too long for this not to be corrected.

Thread: MEW200
11/02/2013 15:13:15

I also was rather disappointed with the 200th issue. It seemed somewhat lack-lustre.

I can't help thinking there was a section missing from the Sheet Metal Forming article. It mentions a "main roller" in the text, and specifies to note that the ends are of reduced diameter, but there is no drawing for it. A "main roller" is not shown anywhere.

Not knowing how the complete device is supposed to work, I confess that I don't see how the parts in the drawings are related. A total GA with part names or numbers would be a useful addition. As it stands, I don't understand it sufficiently well to start making one, even though it seems like a useful tool.

In the "Special Interest Books" section of "On the Editor's Bench" is the sentence that starts with "You can find an advert...". It doesn't exist in my copy.

Thread: 3 Phase invertors for a Myford ML7

Hi Andrew,

I've fitted Mitutoyo S500 inverters to my mill, bench drill, and the lathes and mills of various friends. They have all proved very reliable and I can recommend them. I've fitted the E500 unit to my lathe 'cos its 2HP motor was too big for an S500.

Regards, Gary

I apologise for any confusion - I had a really senior moment when I wrote this - I meant MItsubishi, NOT Mitutoyo. By the way, the Mitsubishi S500 units have the parameter pad built in. I've added some photos that show the two S500s mounted under the lip of the swarf tray of my Centec mill, tilted upwards so they can be easily read by glancing down. The remote controls are attached to the end of the table.

I agree with John about the quality of the manuals though. I wired my first S500 up on the bench - it was the first time I'd ever seen an inverter. I could easily control the direction and speed of the motor from the built-in pad, but when I added a remote external switch and potentiometer as shown in the User Manual it was totally inoperative.

Several calls to Mitsubishi agents resulted in advising me to check the parameters again, although one said to send them my settings and they would sort it, which I did - I heard nothing more.

I downloaded another (thicker) manual from the net and read it carefully. It turned out that the 55 page "Basic" manual supplied in the box was written for the American and Asian market, and the unit was wired accordingly. The 181 page "Detailed" manual showed that a little jumper plug controlled the wiring - one way was for America, the other way for Europe. I swapped the jumper over and the external controls worked.

Although the manual included in the box went into such details as specifying the size of the screwdriver needed for the terminals, it said nothing about the significance of jumper plug.

Despite this, they are good inverters.

Thread: Favourtie Finishing Tools
09/08/2012 08:27:26

Thanks Jason, and thank you Mike - I've made 3 tool holders (1 for me an 2 for friends) based on your design, but for larger lathes; they accept 1/4" square HSS bits and work very well. I made a different sharpening jig to yours.

I use the tool for most turning ops,and found that rounding the tip a little extends its life.

I use my tangential tool (**LINK**) for almost everything except left handed cutting and interupted cutting. It can make deep cut with a reasonable finsh and fine cuts with a good finish.

Mike

Sorry Mike, but the link doesn't work - it tries to go to http://,ikesworkshop.weebly.com/tangential-tool-holder.html

which doesn't exist.

Thread: Printing doesn't work
08/10/2011 17:40:58
Hi Dave,
I selected the page, right-clicked on it, and chose "Print". It produced nothing intelligible.
I then tried your way and it worked fine, so many thanks for your interest and advice.
 
There's clearly a bug in the magazine viewer though, choosing print by right-clicking should print the specified page, but it doesn't. It should be reported as a bug, but I don't know how.

Prints perfectly for me
 
Weird, I just tried again and got the same result.
I'm using Firefox 7.01 under XP Pro+SP3.
Here's a photo of what I get when trying to print page 58.

I tried printing a page from the digital version of Issue 182, but the page chosen gets overwritten with a copy of the digital index page (not the magazine index page). I get a printed page, but it's contents are completely covered by the digital index, with blanks instead of the page thumbnails.
Is this obvious bug going to be fixed?
Thread: Michael Cox Tangential Tool Holder- MEW 179
02/09/2011 13:00:04
Posted by chris stephens on 02/09/2011 12:16:07:
For general purpose use the V jig is superior to the jig in the previous post, which will work best with the the Oz style tool, as it is intended more for cutting in one direction only. As I have said before the striations favour one edge only , but the V one favours both cutting edges, so will also cut equally well on the back cut and when facing.
 
With the V-jig the striations are the same for both cutting edges, but, since neither are perpendicular to a cutting edge, both are less than ideal.
Well, that's how it seems to me.
I don't have an axe to grind about this; I simply worked the angles out for the Oz style jig, which seemed to be rather easier to make than the V one. It certainly seems to work OK.

Thread: tilting vice
30/08/2011 07:58:49
Hi Nobby,
No, the m/c doesn't need to be level.
The digital angle gauge is zeroed when on the table, and thus shows the inclination of the vice relative to the table when placed on the vice. This is pretty easy 'cos its magnetic.
It's not, of course, as precise as using a sine vice with gauge blocks, but 0.1 degrees is more accurate than a degree scale, and much easier to use. Another consideration is that sine gauges get progressively more cumbersome and less accurate at angles greater than 45 degrees. For a 5" sine gauge the difference in height of gauge blocks to distinguish between 60.1 and 60.0 degrees is 0.004356".
For ultimate accuracy, the sine gauge (vice) is king, but for most jobs 0.1 degrees is acceptable.
The vice I use can tilt on two axes, and the angle gauge can handle either with equal aplomb.
 
Regards, Gary

I've got a tilting vice with a degree scale, but since purchasing one of those little digital angle gauges I don't use the scale any more. The angle gauge is far more accurate and much easier to read.
Thread: Warning - Coventry Model Engineering Society web site
09/08/2011 13:41:10
I'm a member of the Coventry Model Engineering Society (CMES) and can reassure you that, contrary to appearances, the site is not infected.
We noticed the problem some 6 weeks ago and contacted the company who host the site, but unfortunately they so far haven't acknowledged that the problem is with their hosting and, instead, provided some useless information about security. So it's unlikely that they will fix it any time soon.
We have done everything possible to prevent the files on the website being altered but so far to no avail. Unfortunately, with a hosted solution like this, we are affectively renting space on someone else's server, over which we have no control, leaving us with limited access to change things.
We've done a lot of research into the problem and the sad news is that, although there is a problem with the website being 'infected' , it's not actually a virus or malware, even though many virus checkers and some browsers interpret it as such.
Unfortunately this doesn't help the reputation of the club since few people will realise this, and instead will accept that it's a virus, and who can blame them!
A permanent solution is to transfer the entire site to a server that we administer, but this is being delayed by the bureaucracy involved.
As a short term solution, whenever we detect that the problem has recurred, we will upload the website to the host's server, resetting all permissions, and replacing any altered files. We last did this on 6th August.
I hope this alleviates your fears.

Thread: What happened to the conclusion of CNC 4th Axis?
03/08/2011 13:34:56
The 4th instalment of the series "An Accurate CNC 4th Axis", published in Issue 178 of "Model Engineer's Workshop", ended with the message "To be continued".
It didn't appear in issue 179, and is not present in issue 180 that arrived this morning.
Anybody know the status; was the message wrong, or should there be another instalment?
