Brian and David, Yes, I have a lot of leftover spare parts - gears, towers, shafts, bushings, screws - all the little internal parts that wear...
Tom and all, Sounds like you are doing an interesting project. Please keep us informed as to your progress. I have placed all my MTL F7 repair...
David and all, LED headlight circuit boards have been designed and should arrive next week, I found a manufacturer that could scored them into...
Further to this - one of the reasons for the difficult assembly of MTL F7 LED headlights is that my previous version did not use an etched circuit...
MTL F7 LED Headlights Hi Bryan, My hands and vision are no longer accurate enough to make these anymore, so am trying to get my stepson to...
Good Idea! Anything that holds the trucks in position against the chassis half while allowing the assembler to lower the other chassis half...
An important point not mentioned in the motor cleaning article - check the wheel gauge using the MTL #920 track gauge with the axles removed....
Quoted from David F. "MOST IMPORTANT OF ALL -- do this process in a big box, if you can, so if/when the springs go flying you have a chance to...
Update to an old thread... I see many MTL F7s of varying ages. The old ones have beautifully polished wheel flanges, almost perpendicular to...
Does any know if a Digitrax DZ123 decoder retains the momentum operation in DC analog mode if CV03 and CV04 (acceleration, deceleration) have been...
There is also a paste to dip a hot soldering iron into that cleans and tins nicely prior to doing a solder joint. Called "Tip Tin" from Plato or...
I use momentum and enjoy it, makes gentle couplings challenging when time response is set short for single loco yardwork, and when set long can...
The schematic for for the linear ramp generator. For a complete description of circuit operation go to...
The RC (resistor capacitor) method simulates momentum but with opposite rate of change of speed at slow speed between acceleration and braking....
A nicer momentum effect is one that maintains the same acceleration and braking rate at all speeds. The blue trace is the speed setting, the...
Thanks for your help, managed to get some thumbnail images to show up. In step 1 there are two 'Railimages", only one of which leads to "My...
Yes, please help. Have 9 photos stuck in Railimages and still cannot figure out how to transfer them into this thread. Where is the icon that...
Notes on MTL GP35 dis-assembly, cleaning, and re-assembly. - by Glen Chenier For those into Do-It-Yourself locomotive repair, this is a...
The wormshaft with bushings tabs properly seated into their right side chassis slots will lie perfectly straight. If not straight, there is a...
