gr.king Posted September 9, 2023 Share Posted September 9, 2023 I've noticed for quite some time that un-necessarily over-tightened screws are a common feature of all sorts of newly made items, often so tight that if screw removal is necessary, then the amount of force needed to grip the item in question, combined with the force that has to be applied in order to keep the screwdriver in the screw head as well as to turn it, runs a very high risk of breaking some part of the item. In some cases, the ex-factory screw can be seen to have already cracked the part through which it is screwed! Cross threading is not unknown either. I assume this is due either to factory use of power screwdrivers (robotised?) needlessly turned up to maximum torque, or to the employment of angry gorillas issued with screwdrivers featuring a tommy-bar for maximum leverage... 2 2 3 Link to post Share on other sites More sharing options...

I also wonder exactly what QC requirements the commissioner has specified. While stuck screws or bolts on model locomotives are a pain in the whatsit, in certain applications the result can have very serious consequences. Carbon fibre parts on racing bikes being an example that I have come across. Bernard 2 1 Link to post Share on other sites More sharing options...

stewartingram Posted September 9, 2023 Share Posted September 9, 2023 That Hornby plug and socket has been pinched from the computer/electronics world. As that was my job before I retired, I actually have no difficulty with them (broken wires aside, not that common). A small pair of electronic pliers does the job for me. I believe Simon Kohler reacted himself to complaints about them, and he sourced the tool now available. I strongly suspect that if one looked (try RS Components or Farnell for a start?) the same tool would be available at a fraction of the price. I've never looked myself though. 2 2 Link to post Share on other sites More sharing options...

(Without the couplings of course). The photo is from Hattons and the item is 37-075v in case your son doesn't already have one. Tom Good evening, He does! It was given to him by a friend (apparently there was an actual wagon, though it could be a work of fancy - I don't know). I applied the BR PO number (I have no idea whether it's correct), disposed of the horrid tension-locks and weathered it. Whether it would be seen at LB in 1958, I have no idea (unlikely?), but I like the notion of having a wagon with one's name on it. Contrary to popular belief, I do have many RTR items of rolling stock on LB, given that most of them are accurate at source. All I do is lose the couplings (immediately), detail/modify as appropriate, then weather them. Regards, Tony.

RMweb Gold Popular Post Tony Wright Posted September 9, 2023 Author RMweb Gold Popular Post Share Posted September 9, 2023 The mention of storing models when not in use - highlighted by Barry Ten's (Al) entirely non-boring arrangement of little 'cubby holes' for his spare locomotives - set me thinking. I have nothing so fancy, but it prompted me to look at how I 'store' my locomotives when not in use. The following images might be of interest............. Spare freight/local passenger locos are kept on two shelves at one end. Spares for immediate use are kept on a shelf at one end of the fiddle yard. Locos for use on the trains in cassettes are kept on a shelf at the other end of the fiddle yard. Further large locos are kept on a shelf underneath the fiddle yard. Those not immediately required are kept in drawers......... A mixture in this one. Almost all V2s in this. Anyone fancy diesels? Particularly Deltics? Mainly A3s. And more goods locos. The oldest locos seen above are 50 years old now, so I've amassed quite a few over the last half-century. Along with the 40-odd needed on the layout at any one time, then it's quite a collection (some others are in boxes underneath the layout!). Locos are changed once a month, so, with at least four times more locos needed than to run the sequence, then each gets a go (approximately) three times a year (they're hardly likely to wear out!). Since over 95% of the locos seen above have been built by me (apart from the diesels), then I question my 'sanity' at times, but it is a most-absorbing hobby. As for the number of lamps and crew members needed, well.................... 28 3 4 1 Link to post Share on other sites More sharing options...
RMweb Gold Popular Post Tony Wright Posted September 9, 2023 Author RMweb Gold Popular Post Share Posted September 9, 2023 Of course, there are the spare locos for the smaller bit of LB............. On top of the 'light blocker' at the north end of the main line. And in the middle. And on a shelf above the MR/M&GNR. There are a dozen more locos in boxes underneath, so plenty for the services on the little bit. Again, I've made most of these. 25 2 1 Link to post Share on other sites More sharing options...

Bernard I wish I had committed to memory the explanation given by one of my mechanical engineering lecturers - complete with equations providing the mathematical proof - of why no matter how much you tighten a nut on a bolt thread, the first three threads will carry something like 90% of the load. So further tightening does nothing except eventually deform the threads. 4 1 Link to post Share on other sites More sharing options...

It is almost as if they think "That way of doing things that has worked perfectly for years...... we don't want to do that".

In a previous life I had to hunt down and physically destroy a large (and by the time we had noticed, well-distributed) consignment of screws that had been obtained for a very good price, but had the yield stress of mild cheddar. The rework process after fitting one of these to an expensive CNC machined product housing was time consuming and costly. 3 Link to post Share on other sites More sharing options...

Thanks Jonathan, I do Hoover the floor from time to time, and the walls/joists, but it's on the railway itself where the spiders are a real pest. They spread their webs where the main line is covered, resulting in the first loco run (after as little as a few hours) appearing with its front end festooned. I poke a feather duster through, but they're very resilient. Signals have 'scale guy wires' installed. Ironically, some of the spiders are eaten by bigger spiders! I'll try the lemon cleaner. Someone suggested leaving peppermint sweets (Polos?) in the most-affected areas. Might that work? Regards, Tony. 1 Link to post Share on other sites More sharing options...

RMweb Premium Dominion Posted September 10, 2023 RMweb Premium Share Posted September 10, 2023 (edited) It is fairly common in Canada to have cottages by one of our thousands of lakes. Spiders have a field day near the water especially with its breezes. We spray a repellant around the outside of the cottage when it gets bad. It does not need doing every year. It significantly reduces the number of spiders inside the house too. If you don’t like the idea of using a chemical you could propel something that is easy to clean on your first run each day. I use one of this Dapol wagon mounted vacuum cars occasionally. It wouldn’t get the spiders but it might get some loose stuff, and eggs perhaps. It is also much easier to wipe off than a loco ! Tom It also gets small parts that have fallen off :-) Edited September 10, 2023 by Dominion 1 2 Link to post Share on other sites More sharing options...
