hiwin linear rails on ebay

[shelbygt500buddy]

Hi i found hiwin linear rails on ebay about 4 foot long comes in pairs with 4 trucks. By the time i did the math on the custom made rails with angle iron and the crazy expesive v bearings i decided for the little extra cost to go with the linear rails look into them see if they will work for you im very pleased with them.

I saved money where i could. I work at a sheet metal fabrication shop so i knew where i could change some things... I didnt have anything cut out by laser. But i wish i had now but its to late. But this is the modified z and x axiis.

Impressive! That must had cost a bump! Did you shim the rail? & how do you make the rail straight?

[shelbygt500buddy]

The price was about 500 in the end i believe. But the best way to get the rail straight is a laser jet. I used a cnc punch but the problem turned out that the punch slightly warped the 1/4" material so i had to restraighten it which led to boaring out the holes in the rails in some locations. Then i tapped the wholes with a 1/4-20 roll form tap. And all the holes where precisely placed so all i ahd to do was mill the end of each rail till the nested perfectly together. I have not shimmed my rails yet since I have not finished everything on the machine and its not sitting where im keeping the machine. I know the machine wont flex much but i figure its a waste of time at this point.

Kyle,
I've been looking at linear bearings too. What size did you use and how are they holding up? Also, how did you determine size?

Thanks, Terry
