New motor cradle/mount (scratch built) for (Treble O Lectric) Lone Star F7 (idea phase)
Posted by Safety Valve on Tuesday, May 21, 2019 4:29 PM

Hi all, so I have been thining of another way to re-power the motor of the Treble O Lectric F7 

I am going to be making a scratchbuilt motor cradle or motor mount using styrene to put inside the original cavity of where the orignal motor sat, one way to secure it (The motor mount or cradle) in particular is to fasen it down by gluining it (With CA or Super Glue) or bolting it down, and soldering on the nuts after the bolts have been fead through, (The motor cradle would have to be hollow to allow this to happen. Big Smile )

I could remove excess matirial with the dremel (The end of the bolt that is facing upwards) , I could then slide in the new motor and superglue or solder on an extention to the orignal motor shaft with a bit of brass or styrene rod, I'll probably build mine so it is powered by the rear truck, since I changed out the front electrical pickup truck for a dummy one since I feel like it is more accurate to the Tri-ang Railways F units from the 50s and 60s (In my Personal oppinon) that they used to have in their transcontinental range, like Lone Star had with theirs which in my oppinion had nice ranges of good models to run.

I'm interested to hear your thoughts on the matter???? this is all in the idea phase and I'll be very excited to try this idea out Wink

I would suggest using Amazing Goop to secure the motor, It remains slightly flexible and absorbs vibration and motor noise.  I’ve used it in over thirty locomotives without a single problem.
 
It is a bit gooey to work with and takes a couple of hours to fully set but well worth the effort.  You will have to keep the motor in the correct position for at least an hour.
 
Another advantage of using Goop is the motor can be removed fairly easy with a sharp #11 blade and long nose pliers. 
 
When fully cured (24 hrs) it is very strong.  The motor in the picture below is glued in using Goop and it is anchored good enough that it doesn’t move even under a lot of torque, the plastic gears do not slip at all.
