Before trying to fit the wheels, it's important with unique (not off the shelf) suspension arrangements, to check alignment as you progress. Once the rollers are in place, for instance, there's not a lot that can be done to adjust them, where there's a bit of movement possible in the sprockets and idlers. Ideally, the centre lines of the idlers and sprockets should match the rollers' centre line. Thereafter, the wheels can be made to line up with this default by using washers and spacers.
Crucial too, is ensuring that the centre line of the moving components, corresponding with the line the Track horns will sit in, and follow will allow the edges of the tracks to avoid contact with the hull walls, and the mudguards. Before I fitted the sprockets, everything seemed to line up nicely. Afterwards, the dynamic changed and I had to file 2mm off the inside of the rollers, and remove the washers I'd fitted in the idlers. Those were put there to reduce end play. The ruler now indicates the true line I was aiming for. The Cromwell is just there for size comparison. (The Comet should be wider and longer than the Cromwell. More of that later.)
These are the nylon spacers I've used before, for the wheels. The wheels have twin bearings, but would actually rub against the hull sides if some sort of spacing provision on the axles isn't catered for.
So...if you happen to buy the kit with wheels, and arms, etc., don't assume that they're ready to go once assembled. They won't be. A long way from it, in fact.
- Nylon spacers for wheel axles.
- Comet- track horn centre line checking...
Now, I have a lady guest appearing tomorrow, who'll be staying quite a while....and so it's time to tidy up my manly pad, and stash the boy's toys away..
When I can sneak a minute in, without causing a social gaffe, I may have to borrow the Cromwell's nice Pz IV metal tracks to test the Comet, as they're hard (and expensive) to find online just now. The plastic ones
can go on the Crommie.
