    800x600 moving gantry cnc router build.

    I want to mount short gantry sides to 20mm hiwins.
    I want the gantry mounted on top of carriages, with weight centered instead of mounting them side on.

    I have came up with this little aluminium mount/adapter that will attach to the gantry sides with 3x M8 bolts.

    I'd love some comments on the concept... is there a better/easier way?
    Does it look stable?

    I dont know what im doing LOL, please guide me : -)

    If the parts are made as rigid as they should be the weight will be centred even if the vertical plate carrying it is not.
    You think that's too expensive? You're not a Model Engineer are you? :D

    I think I'd be more inclined to use more smaller fasteners instead of 3 M8's, that way you should get a more evenly distributed/less distorted and stronger join between the parts.
    I'd probably go for a row of M5, or maybe M6.

    Complicating the jog unnecessarily. Hi-win rails won't even know they have that gantry on there back so just keep it simple.

    I was initially looking to bolt gantry end panel into side of a 20mm plate on the bearings, but I didn't feel comfy with it.

    I'll put some thought into that. My thinking for 3 m8 was as an adjustment/shimming point when I get to tramming stage, but I think you're right. Thanks.
