Standard Gauge Baldwin Gas Mechanical

Mike,

the mesh in your top photo, between worm and the first gear, is far too slack.

The worm teeth (tooth, there’s only one!) should be close to the bottom of the wheel “valleys”.
Not right down, but to me the pitch line is completely incorrect.
It’ll run, and maybe quietly, but the gear will wear out very quickly.

I'll have a look tomorrow. It should be easy enough to adjust. :thumbs:

How is the motor attached to the gearbox? I can't see any screws.
There's a couple of little screws that screw into the face of the motor. There's two sets of locating holes in the gearbox, to allow for the best access to the screws.
Hope this helps.

Hi Mike, that looks better.

The top photo looks perfect

The lower one suggests that You should be able to go closer still until the teeth on the wheel “just don’t” touch both sides of the valley on the worm - if it does touch at the root, or both sides, that will create friction but if it doesn’t do that it should be ideal.

Great photos btw :)

That's what I would expect, but I couldn't see them, sorry

I've managed to get it a bit closer. The following picture makes it look like there's still a relatively large gap, but any closer and there's a massive increase in friction.

Thanks for your compliment about the photos. I'm just using the camera on my Samsung A54 mobile phone plus plenty of light from my anglepoise.

Hi Mike, that looks loads better. The clearance between teeth looks generous, but in reality….?

probably less than a (blue Rizla) fag paper, which is obviously the universal dimension to which we all work…

I haven’t been a smoker for well over twenty years, but I have a pack or two of Rizla blue in the modelling bench drawer. They are very thin rice paper, and a useful thing to have.

I've continued adding the cab components.

The roof is the only part so far that I've struggled with. Getting the folds right has been very much trial and error. Fortunately any gaps should remain in shadow and out of sight.

I repositioned the fuel tank on the roof, but realised it was too high. The mounting brackets have been accordingly shortened. I've also rounded off the fuel tank ends a bit, and extended it as well.

A bit late, but I am enjoying this project very much.
Here is a Baldwin converted to standard gauge I discovered in Switzerland, in the Rhone Valley

Thanks for sharing your pictures. :thumbs: They are really helpful. Although I'm mainly basing my model on the one at Apedale, I'm not averse to incorporating details from other prototypes.

I'm pleased you're enjoying my little project. Despite me modifying parts of the kit, the build has been a real joy. Testimony to the skills of the designer of the kit methinks.

I just had enough time yesterday to make some pickups to enable a test run to take place. Initial results are very encouraging. More soon.
