Re: traction motors for 32 and 45mm gauge

It is a combined gear, here's a link . Unfortunately ebay links don't stay current for long, you can usually find all the parts by searching though. Aliexpress has pretty much the same stuff. I am struggling with the final drive gear, the 40t one. I can find that size, but not with the cone boss on...

Re: traction motors for 32 and 45mm gauge

These look really useful. In the instructions the second stage is 34 plus 12 teeth, Did you buy this as a combined gear or is it two seperate gears ? I have had a look and can't see a combined gear. Or did you get it in one of the gear packs. Keen to have a go at this to would be pleased to get a p...

Re: traction motors for 32 and 45mm gauge

How trivial (or not) would it be to design / print a cover for the gears? I assume these are designed to be axle-hung, so will need some sort of mount/carrier? Phil.P Two of the pictures are with the top half of the gearbox case removed to show the gears, the other two show the assembled unit which...

traction motors for 32 and 45mm gauge

The updated version of the heavy rail traction motor is now online. There are a number of improvements over the early version for ease of assembly, you no longer have to cut the motor shaft and the case is screwed together with self tapping screws rather than nuts and bolts. Uses the same gear set a...

Re: The Cockatoo Creek Tramway

I had to do a search on the thermo electric tram and read about its story, it just looked so weird and awesome. I really love the outside-the-box thinking that went into it.

Re: Braking systems

A little more on this: The motor controller is programmed to hold, rather than be 'off', when you return the speed control to zero. - This can be altered in programming. One thing I have noticed, compared to the Rx65, is that the speed-change is a lot more responsive (instant) this is something I h...

Re: Braking systems

As it turns out this problem had a rather mundane resolution. I was in the process of designing a servo operated friction brake, but before I had a chance to test it in service I ended up cooking the motor controller on 8M, the first completed motor car. https://i.imgur.com/fe2IYwZ.jpg I lamented my...

Re: Braking systems

That's a nice looking model of a 2 car Doggie set. To be prototypical, Doggies and Taits only had Westinghouse automatic air brakes. The Butterboxes, being locos, had the addition of straight air brakes for the loco only. The first use of regen brakes on the VR electric fleet was the L class I thin...

Re: Braking systems

How about combining the two? Having a servo that operates a pot. So you have rheostat braking you can apply sloftly or hard. Maybe you could even fit a pushbutton to be hit by the servo arm at the end of its travel for the emergency short circuit brake. I have this emergency shortcut brake on my 5&...

As trains have become increasingly heavy on a steeply graded line a very 1:1 scale problem has become apparent, the need for a working train brake. I'm wondering if anyone has dealt with this problem before, and what solutions did you come up with? The control system I use is micron radios and the m...

Great slow running (through the day and into the night). Really liked the clackity clack through the pointwork.

Re: Noisy gears

so its difficult to know what the correct mesh should be. Rule of thumb used to be to put a piece of fag paper between the gears and move them together gently until they stop. I'm sure that offends the mechanical experts amongst us but it used to work. :roll: That's pretty much what I did. Measure ...

Re: Noisy gears

I haven't had any real issues with noise in the traction motor gearboxes which use 0.5m nylon gears. It is important that they mesh correctly though, even a small misalignment can make them noisy.
