This post has been a long time coming. I’ve had to wait for some parts, and then it wasn’t until they arrived that I found I needed more.
I wanted to add metal running gear especially as the Mato metal tracks have extensions and the plastic bogeys look a bit ordinary. The Sherman bogies have lots of bits that need paint coverage, so I had to dismantle them and prime and spray them. That’s where I found out how dark Tamiya’s Olive Drab come straight out of the bottle.
Once again Mato and Heng Long parts don’t play nice together. The bogey mounting systems are totally different. The Heng Long bogies screw on, but the Mato's have clips inside the hull. Nothing for it but to open up some holes. The original plastic spigot is on the left, the middle hole is the first Dremel trim, and then the right hole is the final result.
But even after carving out the mounting holes, the bosses won’t go past the gearbox cases. So, I had to trim them off and then glue them in permanently. No going back now.
Another problem was the Mato sprockets which had to be reamed to have the drifveshafts fit. Even then, the driveshafts are too long. The centre of the sprocket lines up with the outside edge of the wheel rubber, so I had to shorten them and redress the shaft's flat face.
In researching other Sherman builds, I found a Youtube clip of a Japanese builder fitting flanged bearings to support the drive shaft. They are supposed to be a press fit, but a light dress with a file was required to get them in.
Eventually it all went together and a quick test drive went well without any thrown tracks.
