The Starter Palaver....

... continues. I dug out an older starter motor and removed the Bendix in order to weigh up the possibilities of the Darracq system I described last week. What I hadn't thought through was that most starters have one of the armature shaft's bearings set in a separate casting surrounding the Bendix gear, instead of in the main case.

Needing an up-to-date high-torque starter, it took some time to find one with the Bendix in free air - so to speak.

I eventually found and ordered one for a VW 2.8 diesel. In removing the Bendix gear, I saw that when the solenoid was energised, it caused a fork to push the Bendix gear into the flywheel ring gear as the motor itself began to turn. Having removed the Bendix and the fork, I'm hoping that the motor will still work. If there's some electrical switch involved (that wasn't obvious in the assembly) I'll have to dream up a scheme to trick the thing into getting going.

A chum popped by to have a crack in one of his alloy wheels welded up. I first took advice from Learned Counsel who, back in the day, was always patching up rally car wheels. A good 'V' along the crack and careful cleaning was recommended; the heat from the welder expanding the material would reveal any extension of the crack if it wasn't at first wholly visible. I also checked that the wheel wasn't all or part magnesium. That would have brightened our day!

The Lacy Scott vehicle auction is to be held this weekend and Counsel and I were drafted in to get a few of the cars running, the most interesting of which was this BSA Scout. Front-wheel drive was a rarity in the Olden Days; the Scout's gearbox (in front of the engine) and gear lever operation being much the same as the Renault 4.

This 350cc Raleigh would look nice hanging on my sitting room wall. I've always liked a hand-change, but a hand-lever instead of a twist-grip throttle would be awkward in traffic.

For inspiration, I remounted some of the body formers on the chassis of the Special.

I'm definitely going to fabricate an ash frame, and having an idea of some of the hoop dimensions would be a good starting point.

Visualising and translating into wood the shapes of the components that'll make up the frame wasn't going to be easy, so...

... I pulled out some wall insulating foam that was over from the stores shed build...

... glued them together and started carving. It's a bit of a palaver, but it's a start.
