Drive cont...

Remove the motor assembly and re-drill all the front shaft guides making sure not to drill through the shaft guide plate. This process should only remove enough material to allow the shafts to freely rotate in the shaft guides, there should be little or no play but also no binding.

Put the motor assembly back into position making sure all three shafts insert into their respective shaft guides. Tack cement several support bars to hold the front guide and motor plates in proper alignment. Cut and drill shaft guides for the rear shaft guide plate. Place the two motor shaft guides onto the motor shafts and apply cement to their outer surfaces then place the rear shaft guide plate into position making sure to align it properly using the edge of the bottom plate as a guide. When the cement has cured remove the back guide plate and repeat the procedure for the rear worm gear shaft guide making sure the worm gear shaft remains in perfect alignment.

When the cement has dried remove the back shaft guide plate and re-drill the guides as you did with the front shaft guide plate. Place the back guide plate into position making sure each shaft fits into its respective shaft guide then tack cement several support bars on the top and sides of the drive. Once the cement on these has cured you can remove the bottom plate and tack cement several support bars across the bottom of the drive. The entire drive unit should be very rigid at this point and you can test the drive by turning each motor with 5 volts.
