I wouldn't regard myself as a model engineer (too many vices for that
) nor am I particularly interested in machining
. However, I am an engineer, and I am interested in engineering and the theory and understanding that goes with it.
The subject of build diaries is a difficult one. Some are boring and uninformative, basically just a series of pictures with no explanation, leaving you wondering how did they do that, or how did they ensure that those features lined up, or why they bothered? On the other hand it is very time consuming to write a coherent and informative build diary with some form of overall narrative. I would regard that by 'Garry_C' as one of the best on here. It has also been good to see him learn, and then move on to more complex operations under his own steam. I run a build diary for my traction engines on the TT forum:

If anybody cares to skim through they will notice that there are very few replies, unless I've asked a specific question. That seems to be the nature of most build diaries, good or bad. However, there is a 'thanks' button on TT so people can show appreciation, so at least you know it's being read. I also post occasionally on MEM, although there, again, with one exception, I get few or no replies. So why don't I post here? Let's look at some of the comments I've had in response to posts over time, in no particular order:
1. I have a well equipped workshop with mostly ex-industrial machine tools, so the techniques and methods I use are of no relevance to the average model engineer
2. I regularly use a CNC mill, but that's cheating and shouldn't be allowed – and as for 3D printing, well really, quite beyond the pale in polite society
3. I am a cheque book engineer
4. I've got an engineering degree so I can't possibly be any good compared to the man in his shed
I also run a theory thread on TT, although it has been in obeyance for some while due to other pressures:

Clearly this thread is specifically related to traction engines and is therefore probably best hosted on a traction engine specific forum. However, I would never attempt this type of thread here. Why not? This forum has always had a bit of an 'edge' and there's nothing wrong with that. In the past I've been involved in full and frank (!) discussions on bevel gear theory and the design and manufacture of worms and worm wheels amongst other things. And very interesting discussions they have been. However, I get the impression that the forum has become much more dogmatic, with many 'experts' laying down the law with no quarter given. The thread I started on helical gear theory got rather hijacked by some long and rambling posts, which is largely why I decided to duck out.
I have suggested to a moderator that rather than a 'Tea Room' area we need a 'Wine Bar' area (pun intended) but sadly it seems to have fallen by the wayside. ![sad sad](data:image/gif;base64,R0lGODlhAQABAAAAACH5BAEKAAEALAAAAAABAAEAAAICTAEAOw==)
