Rob,

Thanks for the pics of your torque reaction link. A solution very elegant in its simplicity. :thumb

Cheers,

David

Get too close and you may also just find the second controller in your hand......... ;)

I suppose logically there is a possibility that the strip might bend back or forward if the chassis was putting up a lot of resistance, but at that point I suspect the chassis needs more basic attention than worrying about the reaction link working properly.


In reality the strip does flex slightly and was only fitted for the purpose of testing just the chassis. The design is such that the motor sits snugly on the removable lower boiler section. The space between the top of the motor and the top of the saddle tank is filled with lead so at most there is only about 1mm of movement.


I know there ain't much room in these Highlevel kits above and below the motor but a little over 1mm ought to be enough as that's the normal design movement limit on a CSB. What you are trying to avoid is the motor pressing down, or up, on the chassis/boiler 'cause if it does it affects the vertical movement of the driven axle. While this is obviously true for the natural rise and fall of the horn bocks, it is also true of additional up/down movement at the far end of the motor due to it's tendency to turn round the axle, hence the need for a reaction link. Without a reaction link stiffness in the chassis can result in the chassis hopping as the driven wheel is pushed down when going in one direction, or "lifting a leg" when going in the opposite direction.
If your getting much flexing I'd beef up the link so it doesn't flex.

Thank you to all who stopped by and had a chat at Scaleforum. As a first time exhibitor I did not know what to expect but I thoroughly enjoyed myself.
Loco No 1 developed a problem late Saturday afternoon so I was down to 1 loco. It was not until I got home and completely stripped the loco that I found the problem to be one of the front crankpin nuts which had tightened itself. The Loctite I had from the 1980's had failed................although the opposite crankpin is still 'locked'.

Whilst stripped down she was cleaned and I was amazed at the amount of muck.
Anyway, reassembled and running sweetly awaiting the next outing.

Loctite has a "shelf life", if yours hasn't got a "use by" date, it's already too old!

Rob

Was this the cause of the fault which developed in one of the DCC controllers whilst you were away from the layout on the Saturday afternoon.

Tim, I've also got a 'use by' date, it has expired, but I still keep going...... ;)
I was aware, I did a test and it did what it said on the tin, thought I'd chance it.........

I guess the controller was showing an overload because the loco had basically seized.

Hats off to you, Rob. It takes proper dedication to do that with individually placed cobbles. Was it really 10,000+? I don't think I could do it with so many. Does look the part though no doubt about it, a d I guess modelling it this way is the most realistic way to go about it seeing as it was how the real ones were done.

Das clay with a squashed paint brush end appeals more to me though as a method. :D

Just out of interest I kept a tally of the number of batches I cast, after 10,000 I stopped counting but was nearing the end. There is quite an area that has setts.

I had considered scribing or stamping with a shaped paint brush but at the end of the day it was going to take me roughly the same time........
