I've done a couple Pinewood Derby's in the past and the block we were given for the car was a typical rectangular block of wood with no other cuts except the normal axle slots.
However, I am now doing an Awana Grand Prix and the car kit we were given for this race is the "Indy Car Kit" (http://awana.org/store/singleindycarkit/71677,default,pd.html?start=13&cgid=events-grand-prix) and this block has quite a few cuts to the block already. These pre-cuts are making preparation of the car more limiting/difficult than the standard BSA blocks.
Looking at the bottom of the block, the middle width of the block measures in at 1-3/4" and the end width of the block measures in at 1-3/8". The block width tapers down from the middle to each end. The width where the pre-cut axles are located is 1-9/16".
Assuming no additional wood would be removed from the width of the axles and a gapping for the wheels of 1/32" this would seem impossible to make the 1-3/4" clearance needed for the track (1-9/16" + 1/32" + 1/32" = 1-5/8"). The rules state that 1-3/4" is needed for clearance between the wheels, so I assume I need to allow more gapping between the wheels and the body. However, this would seem to be detrimental to the performance of the car?
Is there any hope for this situation?
Thanks!
