I completely agree that the SCD chassis jig is excellent and I've used one for as long as Eddie has, but having replaced it with a
Precision Slot Cars 1/32nd scale CSCRA spec jig, I can honestly say that the PSC jig is a worthwhile investment.
The jig is extremely versatile and covers just about all the specifications for the various CSCRA 1/32nd scale
classes:-
Wheelbase:
From as short as 7' 4" (2.75" - 70mm scale) for 1960s Grand Prix and Sports/GT cars; to 10' 4" (3.87" - 98mm) for pre-war Grand Prix cars and late 1970s and 1980s NASCAR chassis, in 2mm increments. Additionally, the rear axle can be set at minus or plus 1mm, extending the wheelbase options even further.
Overall width:
50mm, 54mm, 58mm, 61mm, 63mm, 64mm
Motor orientation:
Anglewinder, sidewinder and inline chassis configuration are possible, for FC-130, FK-130, FK-180, FF-050 and FF-030 motors.
Axles:
3/32" or 2mm rear axles; 3/32" or 1/16" front axles.
Jig wheels:
For classes requiring a minimum of 1.5mm ground clearance, which covers Sports/GT, Saloon/Touring and F1 & Indy/CART/IRL car classes (including Sports Prototypes, Can-Am, Group C, IMSA, Group 2, Group 5, Trans Am, NASCAR, F1 and Indy cars) from 1963 to 1993:
4-sizes front jig wheels: 16mm, 17mm, 18mm, 19mm (for 1.5mm ground clearance - 3/32" axles / with sleeves for 1/16" axles)
4-sizes rear jig wheel: 19mm, 20mm, 21mm, 21.5mm (for 1.5mm ground clearance - 3/32" axles)
For classes requiring a minimum of 2mm ground clearance (1950s/60s Grand Prix, Indy and F1 cars, although it covers rules for cars from 1934 through 1988):
4-sizes of front wheel diameter: 19mm, 20mm, 21.5mm, 23mm (for 2mm ground clearance - 3/32" axles / with sleeves for 1/16" axles)
4-sizes of rear wheel diameter: 20mm, 21.5mm, 24mm, 26mm (for 2mm ground clearance - 3/32" axles)
Guide pivot:
Since many 1/32nd chassis designs incorporate a central spine or flexi hinge, the slot for the guide post only extends from 68mm ahead of the rear axle (or 67mm if the +1mm rear axle position is used.
This really is a top quality product. All lines and dimensions are engraved and precise.
There is also an "American" version available, with Imperial measurements.
With kind regards,
