Well, here’s where i stand to-date. I have ordered parts from Jameco, Servo-City, and USABEARINGS out of Florida.

Here’s what I’ve ordered.

Harry’s CNC Time – 60$
I purchased machine time on Harry’s CNC machine, he’s going to cut out the machine panels for me from a piece of higher quality hardwood. (Plywood?) You can find him at and He owns/operates both sites. If you are ever in the market for a RIGID SUPER AWERSOME CNC machine, he’s got cast pieces and plans to build a 4×4 Hybrid version of Joes CNC. He charged me 60$ for the time to cut my plywood. Thanks again harry.

I ordered 4, because Jameco has a 10$ minimum order, Or you can pay 5$ order fee, I figured I’d rather get more parts for my money rather then pay an empty Order fee.

I probably overpaid for overspec’d pieces of junk, but I’d love to prove myself wrong.

I know I didnt have to post the specs of everything, but I wanted to justify what I spent on the quality and specs. Everything I ordered this first time around was basically for the Low-Cost Spindle designed by David Carr. You can find the original design and specs here

So… Thats where I stand. I will probably place a McMaster order this friday, I would have allready placed it, but thier online website order system doesn’t like me… I’ll have to call them with part numbers. I hate being on the phone >.<

I hope you guys enjoyed my update… And, I hope you enjoyed the pictures of my goodies!

These last two are just because 😉
