Screw M7

[gixi]

Heeelp ! I just started to build a new cnc machine, my own design... For this machine I did some serious shopping and the major objective was to use linear slides. For the Y axis I found on eBay a linear slide from THK 25mm with flange. The price was good, the items are new but the holes for fixing the slide has a "special" dimension 7mm. Finding screws with this dimensions become a nightmare :eek:. Did someone know from where I can buy such screws?

7mm is a typical hole size for a 6mm screw.

When I finish reading all the info from their site (THK) I realized that is no such screw in the installation guide... :o.
I forgot one of the mottos of this site: READ, READ and READ again.
Thank you Gerald

One more thing: each part of this project before sending to the laser machine was cut with MM for testing. It's good to build a machine using yours .
What can I say: somehow MM is the mother of the new machine :).

do you have a build log for the new machine? at cnczone?

Yes I started the second project and this is the link http://www.cnczone.com/forums/diy-cnc_router_table_machines/127931-just_started_bulding_second_machine.html.
Looking at the new structure, each day I get to the same conclusion:next step linear bearings on my MM.
