Parts
| 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 |
| 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 (?) | |
| 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 (?) | |
| 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. |
