Hey all been awhile since I have posted to the forum. Been pretty busy with school and building a cnc machine for my senior project. Was hoping to build one for myself and its looking like that I am not going to have the time to do so. So I want to try and get some money back from my projects. Need to pay for a class this summer, and I am hoping to get a shiny rock for the girl of my dreams at the end of the summer.

Anyways I can't for the life of me figure out how to post to the classifieds, do you need a minimum number of posts? There is no new thread button. This post would probably fit better there. Anyways here is what I have Will post a pic soon.

4X   92 inch THK 25 Linear rails excellent condition. $300 per rail

2X   47.25 inch THK 25 Linear rails excellent condition. $150 per rail

2X   37.75 inch THK 25 Linear rails excellent condition. $125 per rail

2X   32.5 inch THK 25 Linear rails excellent condition. $100 per rail

2X   22.75 inch THK 25 Linear rails excellent condition. $75 per rail

6X   HSR25H linear bearing blocks. 70.2mm wide 30mm high approx 80mm long with wipes and enclosed bearings, aka the balls don't fall out.  Price depends on what else you buy aka the rails

Also have 6X  Star Rexroth rails that are the 25mm type all about 47 inches long each with 2 bearing blocks. $150 per rail with blocks

And here is the one that will make your eyes pop some. I have 245 inches or just over 20ft of Roller bearing rack and pinion drive. Let me describe it. there are 8 30inch pieces and 1 15inch piece or rack. Instead of gear teeth it has needle bears. The pinion is s 80.75mm 18 tooth gear that fits the needle bearings. This mean you get 245inches of zerobacklash high speed low noise, low friction, low maintenance, low heat drive distance. Gear is on a shaft and comes with two bearing blocks. Basically we are talking a ballscrew of unlimited length.

Would like $1250 for the drive gear, racks shaft and bearing blocks.

YouTube        - Roller Pinion System This is a video that tells you about the drive system. My stuff is exactly the same except instead of having the needle bearings on the pinion, the entire rack has needle bearings along the whole length. And yes he said 36 ft/s which is over 25000ipm.
You won't get a better drive system than this.

Last but not least I have a 3X Keling 381 dual shaft drive motors and a gecko G540 that I want to sell too.

So if you interested in helping a guy out let me know. Shipping will be expensive, but if you live in the New England area I am located in Southern Maine and you are welcome to come pick it up.

Would love to sell as a package, but will probably end up splitting it all up. Would love to here what you all think is a fair price on this stuff. PICS coming soon. Thanks

Lets see if these pics show up
