Looking for an alternative to the overpriced $150+ holders. Can regular CAT/BT30 holders be turned down and a bearing added? Or the tool changer "wheel" be removed moving to something similar to the F1? Can adapters be made? I dont have the machine in front of me (friend has it 600 miles from me) so its hard for me to envision what could potentially be done.

Can the Y axis be extended at all? As is they are extrmely limited. I know on the Chineese conversions people have managed to replace ball screws and or grind away at the base to gain another inch or two and at this short of a throw even 5" would be welcome.

Thanks guys,
Chris
