Parts

Required
Quantity Description Type Comments McMaster Part Numbers[1] McMaster Price
1 box (100) 5/16" nuts Fastener 95462A030 (1 box) 4.56
1 box (100) 5/16" washers Fastener Washers are produced with various tolerances so it is recommended that if buying 5/16" washers, one should check that they do not rub against the outer race of the skate bearings. If one can find 1/4" washers that can fit over 5/16" rod (fairly common), those should be used instead. 90126A030 (1 box) 4.50 (maybe need to look at 1/4" washers)
1 box (100) #6 washers Fastener 90126A509 (1 box) 1.26
1 box (100) #6 1" screws Fastener 90272A153 (1 box) 3.16
1 box (100) #6 nylock nuts Fastener 90631A007 (1 box) 2.48
1 box (100) 5/16" Fender Washers Fastener You only need 6 91090A111 (1 box) 6.26
3 608 Bearing Sets Bearings (any 608 sealed bearing (Mendel Bearing Kits) such as: http://www.thebigbearingstore.com/servlet/the-1031/608-dsh-2RS-608-dsh-ZZ-Radial-Ball/Detail) - 5972K91 is not a good choice as it is unsealed & $$$$ 2.61
1 box (100) M3x10 bolt Fastener Motor Mounting 92005A120 (?) 2.30
2280 mm ~90"/7.5' Neoprene Belting .200" Pitch, 1/4" Drive Belt This is not compatible with the T5 pulley in the git repo (see below) 7959K24 (?) 14.96
1 9 foot smooth rod (NOT GALVANIZED) X,Y,Z bars 8890K41 (3 foot sections, $4.05, 0.005"/foot straight)

8893K41 (3 foot sections, $4.30, no straightness spec, one arrived bent)

8888K41 (3 foot sections, $8.53, 0.005"/foot straight)

All are +/-0.0005" and may bind on bronze bushings if oversize

These are all ground rods (typically called "Drill Rod" in the US and "Silver Steel" in some other parts of the world), and all make excellent choices for your XYZ rods. The more expensive ones offer no practical benefit, but are listed in case the first option is out of stock. You can also substitute stainless steel rods, but they are generally not quite as smooth, and they will usually be more expensive. Plain steel and galvanized rods are poor choices due to the rough surface finish.

1 21 foot threaded rod Frame 98841A030 (3 foot sections) 15.89
4 7/16" x ~1" springs optional, or from a spring loaded pen Free?
