Hi Colin - I am also struggling with the chassis on this kit...
I mentioned in a previous post "The Great Crankpin-throw Fiasco" - I had (have) a problem with the throw of the crankpins. I had beefed up the jackshaft drive with additional scrap etch layers as it looked a bit weedy and then drilled them as accurately as I could on my one machine tool (a pillar drill I bought from the previous owner of my house).
The drill passed cleanly through the etched guide holes. Everything seemed nice and square and was looking good until I came to assemble the parts into a working chassis - the crankpin throw does not even
remotely match the recommeded Slaters Class 02 wheels (which in itself are not correct - number/profile of spokes). Cue much searching of 'tinternet and comparison/scaling from photos (As I mentioned in my reply to Phill above, shots of 06 006 came in particularly useful due to the white painted bosses).
I called the kit designer who has built several of the kits to see if he originally designed the kit for an alternative wheel, but he recommends "sloppy clearances" as the best option. Unfortunately I think the Slaters wheel is the best compromise I can find (although crank throw is the
one thing that is correct). I think the only solution for me is to remake these parts. Unfortunately as you can tell from the dates of the attached shots, I've not exactly been moving at light speed to correct this fault. Maybe I'll manage something for it's 1st birthday...

Drawing a line under the Great Crankpin Fiasco, I'll get on to some actual glacial progress...
I've been working on the front end again - The kit supplies some brass tacks for use as grab irons at the front steps, but I decided to try to replicate the tall tapered ball-top type with some wobbly Black & Decker assisted bodgery.
I chucked up some cut off brass pins to slightly over the required length and simply formed the taper and ball tops with files.
Chucking these up to the correct length helps to keep the taper consistent, but (as usual with free-form bodgery) I made a couple of spares so that I could use the most consistent ones together.
Enthused by my apparent success, I decided to attempt the radiator cap next. I've been searching for a decent close up of this for months - unfortunately this item likes to hide between the horns and the front lamp, but I finally found a
good one of 06 003 at Manchester.
I dished the top of a brass screw using the same method as the grab irons...
The slot in the screw was filled with a sliver of scrap and the bolts represented with brass rod. Filed down it will do for me. Unfortunately my overenthusiastic blowtorch wielding loosened the front lamp, but this gave me the opportunity to correctly mount the bracket on the front (not top) of the radiator.
Last up was the radiator grille. This has a rim, which I bent up to shape before soldering on.
The wire was a bit thick so I filed it down a bit when I trimmed the wire mesh.
