Sanding The Top

Yesterday and today I most of my time was spent not on the storage battery truck but on two flat cars.  Both 48 inches long and 18 inches wide.

I did take the time to use the time to power sand the top of the storage battery truck today, went through 8 pieces of cheap sand paper.  The top of each board now has a chamfer so it is more clear that they are individual pieces of wood.  In addition, all the of the end steps have been broken over with the power sander.

Back to the flat cars.  They are simple.  1-1/8th thick plywood from work, a band of 1x2 poplar around the outside.  Two pine cross members underneath.  Threaded through, from end to end, is a 1x2 x1/8th rectanglar tube center sill.

This is when I had the panic question, will wheels fit under it?  Will I have to go back and gouge out the plywood for these cars to roll?  Rather than measure and do a whole lot of math I decided to make a coupler pocket height gauge capable of supporting the car.  Set to IBLS unloaded height it will tell me if my cars are good or if they need washers.
