It is not too late to fit a ball race to the pinion shaft, so it may yet be done. I have tried to build this chassis such that access is possible to most areas. The weight is 31g front and 32g rear, not too heavy, a fact aided by the low weight of the wheels and tyres. I will be able to shed a few grammes from the front end though doubt I'll get the weight below 60g. One of the K3s has the Beardog (total weight 57g) and runs well on a short circuit but not so well on longer tracks. I'd guess that with the longer wheelbase and wider track, the Delage might be better on the short circuit, but the weight will cut down on its speed for any long straights.
Excellent chassis, with such a good base to work on you can't go wrong. It takes a lot of preparation, thinking work and skills to come to such a piece of art. And sometimes the most difficult thing, is to integrate the parts that makes it a slot car,because these things are not natural to the car.
After playing with those 030 can motors for a while, I've found that any unwanted friction will hamper their performance considerably.
Any friction to a motor will have an influence to its performance, even the gear. On the other hand friction means also breaking power.
I think the greatest concern here, is not if a ball bearing should be integrated or not, but the alignment of the drive shaft it self, between the motor axle and the gear. The slightest difference from the centering of the drive, will have a huge impact. That's why I prefer a plastic or a carbon shaft, it will absorb great deal of the indifference's that could be there.
But there is no doubt that Peter now's best what to do and how to build. This is the art of scratch building in it's best form, and I hope we will see people taking there time and patience, perhaps the most important ingredient in such a build, and try to build the same even if it's a postwar car (thinking on Andy's Vanwall)
Peter I can say no more, than top work.

Well, the plain bearing remains for the time being. The housing will be drilled at 45 degrees on the non-thrust side so that a small plug of felt can be used, soaked in light oil.
The pinion shaft support will be all but spot on. Once the rear axle position was finally determined, the motor mount was fitted, jigged to align with the axle. The same jig was then used to determine the position of the pinion housing.
An alteration is to be made to the front wheel mountings, so alas a delay is almost certain to delay full testing.
Initial testing has taken place, albeit without the front wheels fitted and first impressions are that this rather time consuming project is no waste of time.
Planning is now advanced for the initial body, I just have to clear up an awful lot mess first........

A bit of an update, not so much as because I have done a lot (anything!) but because I've been busy in many areas and just didn't get around to posting. Things have been quiet on this board for a while, so here goes.
The basic body shape is now all but finalised.
Most of the body is made from 0.040" styrene sheet. In some areas this has been doubled up, in other uncertain areas, 0.060" sheet was used instead.
The only flat areas were seen in the previous post, all new parts being formed by clamping to a thin metal former, then heating that former from the underside. It seems to work. The filler is standard polyester body filler.
A slight rework of the chassis is due, with a few recent pictures giving a better idea of body shape, thus requiring a slight tweak of the chassis front end.
A recent development has been the manufacture of white tyres, correct for a number of cars in the mid twenties and earlier.
Here's one of the new pictures, an ex-1926 San Sebastian car circa 1928 in Sweden, this car has travelled the world but is meant to be back in the UK, possibly in bits.

Ah, hello Philip.
Members are recommended to take a few minutes to visit the site mentioned by Philip. Whilst much of the site is concerned with Le Zebre cars, there is a great deal of information on the life of Andre Morel, and through him, Delage.
The photographs are of exceptional quality and have been a great help with regard to my build.
Work on the 2LCV has alas been in the doldrums, as has work on all cars. I'm hoping normal activities will be resumed in a few months time.
