OMG: For the shaper I was thinking short, like one page to include a picture of the broken part, and a discussion of why it broke. Then a brief description of the repair scheme, possibly a picture of the part being machined to illustrate the alignment of the broken parts, and a picture of the repaired item.
Stub: I didn't explain what I meant by thread milling. I have the equipment, but not the cutters, to thread mill worms, but I was referring to milling screw threads which are either specials for which taps/dies are not available, or are on parts where conventional methods cannot be used.
On the issue of copy for articles we'll have to disagree. When I write an article everything is intended to hang together exactly; I'd be right p*ssed off if it was hacked about by the editor. Of course spelling mistakes need correcting, and photographs may need cropping or contrast and balance adjusted to suit the printing process. If it's rambling or unclear I'd expect it to get rejected, or returned for a re-write. I supply drawings as DXFs, and a PDF for reference, which should be ready for publication. If I recall correctly the illustrator does not have an engineering background? Unfortunately in my article on the hydraulic copier errors in the drawings were introduced by the illustrator.
Most of my article writing in the past has been for international reseach journals. There you get a 'camera ready' copy of the paper for proof reading. Of course these papers often contain quite a lot of advanced mathematics, which if printed incorrectly is nonsense. I have seen this; years ago I needed to design some analogue filters based on arbitrary pole/zero positions in the complex s-plane. I found a research paper discussing an opamp circuit topology that was suitable, but sadly the proofreading wasn't up to scratch, as the given transfer function was wrong. In the end I had to derive it independently from first principles.
Fortunately I did include a picture of the equipment being discussed, and an isometric view of the parts being made in my article on the hydraulic copier. That raises an interesting point, given the entrenched views expressed elsewhere on this forum about what should, and shouldn't, form the basis for articles. While a hydraulic copier is an industrial piece of kit, I believe that they are pretty much obsolete in industry, having been superceded by CNC lathes. So should the article have been rejected because it discusses an industrial process, or accepted because said process is obsolete and therefore counts as antiquated?
Peter: Just because you're lathe is not common doesn't mean that an article based on cannot be useful. After all, even for a Myford lathe I don't suppose many people will have the exact model being discussed.
Personally I'd like to see some practical articles on surface and cylindrical grinding. I'm getting on ok with my cylindrical grinder, but I'm having issues with my surface grinder. I have reached the tentative conclusion that the spindle bearings on the surface grinder are badgered, but it's quite a lot of work to re-design the spindle to use angular contact bearings; especially if the problem of wavy finishes is actually down to operator error.
