Getting Cranky

The good news is that the 14BA tap has arrived in the post.

The bad news - for Himself - is that it means he's run out of excuses for not tackling the motion on the power units of 143, our latest Backwoods NGG16 build.


They've now been fitted onto the axles on the front unit and the coupling rods secured in place.

If you're wondering why the leading axle has a plastic collar on it and the others don't, allow me to explain.

The second generation NGG16 kits came with plastic bushes to help attach the cranks onto the axles, so they could be glued in place rather that soldered.

Himself decided that this was rather a good idea for the front axle because that also carries the plastic gears, which are vulnerable to damage from the heat when you solder the crank on.

He tells me that it is 'much easier' to protect the plastic wheel centres on the other two axles, which is why he has opted to solder them.

Readers may make up their on minds on exactly what degree of understatement has been used in the words ' much easier'....

  1. My NGG Garrett kit came with the plastic bushes for the fly cranks. Had to get the old style from Pete as the flycranks kept moving on the plastic bushes. I have soldered them without any problems, except now, one of the gears has stripped and I heed so source a new one and pluck up the courage to strip it down to fit it.
