..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.

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 !!
