Hi Thanks for your reply, I mean How much the weight can handle the base?
Suppose If I want to keep 200 kgs plate to mill, can it will handle? Hope you got my question.
I was thinking to build the base of 5 or 6 mm thickness of square poles.
Ive had some more questions.
1. Do you mean the cutting area would be in 300mm * 400mm?
2. In the video their is no details how you fixed the moving aluminium plate that is on rails.

It looks easy to build the machine, but I will take your help.
I don't know what is your size of Table but my Table was 32*71 Inches table. Ive had some more question but please answer above.
