No 4407 More Errors

Edited By Nicholas Farr on 02/07/2011 13:03:21

When I saw "... he lives in Greece" I cracked up, but at least it was a new one that wasn’t in Jeff Daymans list. “Greek tragedy” and “its all Greek to me” also came to mind.

Seriously; having recently been a victim of this drawing errors problem I was coming to the conclusion that there was an issue in the illustration area, now I believe it to be deeper than that and more of a systemic problem in the way ME is produced. I’m new to this area of engineering but I’d have expected the discipline of getting drawings right would have been second nature to people who’d been in the industry for years. I’d also have thought that these days this sort of problem would be reduced by the use of computers.

So rather than vilifying David and the crew is there anything that can be suggested that would be useful to them to improve the magazine quality? A review of the process? Or even a group that could assist David with proofing the articles before they are printed. They pay the original author, so of course for a fee.

PS: publishing the corrections here isn’t that helpful either as I doubt every ME reader trolls through this site just in case they find a correction. All of the above needs to be consolidated into a “Corrections” item in the magazine. Give the regularity of these issues maybe it should be a regular feature.

I cannot help but draw your attention to 'another one' which escaped the critical eyes up to now.

On page 39 there is an article about making a chuck adaptor plate for the Hobbymat lathe.

The text in the article gives the following data:

Hobbymat spindle flange diameter: 55 mm

Chuck internal register diameter: 56 mm

The drawing clearly shows a boss (for the chuck) of 55 mm diameter, and on the other side a recess (for the spindle flange) of 56 mm diameter.

If someone would produce such an adaptor, trusting and relying upon the drawing only,

he would be up for a nice surprise...

Not the end of the world I admit, but a sign of the quality checks done (or not).

Well I had to leave one for somebody else to find

And lets face it if you are not too pedantic about the concentricity of the chuck it will all fit  (loosly) together that way

Or is that why clock makers use a depthing tool rather than measure out the gear centres

Is it a clock making thing or is there another reason that the OD of all the gearwheels in the clock article seem to be 10-20 thou over size using (teeth +2) *MOD?
