-* 5x 6700zz (10x15x4mm) bearings for the spinner, just buy cheapest ones. They may come packed with a heavy weight oil that arrests rotation, this can be corrected by thoroughly degreasing the bearings and relubricating them with a lightweight oil like Super Lube ISO 68. For example, a soak and spin in 99% isopropyl alcohol, dry on a heated plate to remove the excess alcohol and thin and remaining grease, then a final wash in acetone (if you have all-metal bearings) and additional heated dry before relubricating will ensure the bearings spin freely.
