So far I have decided on the following items for my Joe's 2006 R2 model CNC:
1. Lead Screw and Drill Rod from McMaster-Carr
Qty 2 - 6' ACME 1/2" - 10, 2 Start Lead Screw, Right Hand Turn. Part # 99030A720 - $52.20 ea.
Qty 1 - 3' W1 Tool Steel Rod .7500" Diameter, 3' Length - $18.09. This is $12.94 at Enco - Guaranteed Lowest Prices on Machinery, Tools and Shop Supplies, but not worth paying for another shipping charge, so I bought it here.
2. Bosch 16176 2.25 Horsepower Electronic Variable Speed Router Motor with 10-foot Cord from Amazon.com. The 16176 model is the Motor only from the 1617EVS router. The price from Amazon was $157.99.
3. Bearings from VBX.com per the plans.
100Skate - 100 608ZZ Skateboard/Inline Skate/Rollerblade/Hockey Bearings - $ 34.95 for Qty 100.
R8ZZ 10 Bearing R8ZZ 1/2"x1 1/8"x5/16" Shielded - $19.95 for Qty 10
Next is order the Lead Screw Nut and collers etc from dumpstercnc.com and to continue researching the Stepper and Driver Board options.
