DIY Epoxy composite gantry frame milling machine

[Lee Roberts]

This is looking fantastic John well done,

Example of how the rails will be aligned by Laser cut Then countersunk by me later cams Held by 30mm x M8 CSK machine screws, screwed into the pre turned drilled and tapped inserts glued into the lapped mounting bars. (Prior to drilling and tapping the M6 holes to mount the liner rails). This will be done after the casting has been made, small errors in placement prior to casting is easily corrected here. The cams will also make a very rigid mount for the rails.

I like the idea you've used for rail positioning with the disks/cams, what are the smaller holes in each disk for?

Looking forward to seeing how the rollers come into play!
