Hmm, yes OK, we have heard this as the conventional line, but there are rather a lot of 2mm models out there that have been powered for years and years using direct drive from coreless motors without adverse effect. Could be that they don't actually do many hours running, spending most of their time in boxes, or perhaps the smaller forces involved in such light models do not produce that much stress.

..I agree about the weight factor and to contradict what i have said i have seen on the net a known German precision locomotive site using this system in 1/87, but then again they may have deep pockets ? This was the reason why the portescap gearbox was designed as it was to avoid this problem of thrust on the motor, to insert a thrust washer or shouldered bearings to protect the motor shoudn't be too hard even in your scale, the thing is these motors don't give you a second chance and they cost a lot. One of the best motors on the market for this type of gearbox has to be the Mashima, for price and all round reliability, save the coreless motors for a gearbox without worm. At the end of the day the choice is yours, but it pays to be wary.

Hi, i have been following this thread, very good work, there is though a point i would like to make concerning the Faulhaber and in general all coreless motors. To use these types of motors with a worm gear is not good practise, what you will find is that they will work perfectly in one direction but will be slightly noisy in the other, this is because the worm will be trying to pull the motor axle away from it's natural position and will generate interference around the commutater leading to the eventual distruction of the motor making it useless. To avoid this and when there really is no alternative than a coreless motor you must have a thrust bearing in between the motor and the worm, but what is most important is to ensure that when setting up the position of the worm and it's thrust bearing in relation to the motor this shoud be done with motor axle in it's natural position and not working against itself. In other words the motor axle and the worm shoud not be able to move backwards and forwards away from where it was intended, i hope i haven't confused anyone, it's just to make sure that your expensive coreless motor's last longer, bye.

This really does look good !!

I would go as far to say at least three noughts too much, even at 25 tons per day that would take some doing in the space they have to work in !!

Crazy as it might sound, nothing better than liquid brake fluid !!

Nothing but Hymeks i'm afraid.

Can't say I agree, at all.

 

If anything, getting people to go to both railways - and travel along both lines - will bring in better sums of money to both. If the WHHR - as they had, previously, offered to pay for paths along that particular stretch, then it can only be advantageous to the WHR/FR as it means the WHHR passengers will disembark at their stations and continue their journey on the "other railway".

 

It is notable that the most vocal people in each of the two groups are those who have for years purported a feud of sorts between them. At a time when they should be burying their differences, and working together towards a common goal - better tourism and preservation of heritage - that the WHR/FR has cut the WHHR off completely is a disgrace.

 

It being down to a business case is, I'm afraid, a complete red herring, and simply not true. Other lines in Britain work together for a "greater good" and have fantastic working relationships - that two lines so close together who have a common, shared history cannot is something that will impact on both of them in the future.

 

I already made my thoughts on the FR/WHR clear last year after a particular event on a WHR train. It was settled satisfactorily, but I am not convinced that the same would not happen again, particularly now.

I don't agree either.But if it's not for business reasons then what else ? Spite ?

This has come as no surprise. The WHR/FR want rid of the WHHR as soon as possible, pure business i'm afraid !!
