I have finished the build of my pro machine and I am a stage where I am thinking about the table surface and spoil board. (still have to build electronics)
I have seen machines like the Kronos that use 80/20 extrusion as the table top with no spoil boards, and I have seem other tables purely our of MDF with a spoil board.
My surface is 4'x3'. I plan to cut MDF, starboard and even aluminum. So the challenge of affixing these materials can easily be overcome by inlaying some thing 80/20 (40-8020) extrusions or so I think. I am new to thing, so I am open to advice.
here is what I am thinking of doing:
The idea is to use some woodpecker clamps or others,
T-Track Clamp - Amazon.com
80/20 25-5013
I have some general questions:
1- what is the advantage if any or doing the top like the guys from kronos (all metal)?
2- It is my understanding that I should plane the MDF. The way I have modeled this, there is a potential for no planing because of the proximity in sizes between the MDF and the extrusion I have chosen. My only option would be to attached a second piece of 1/4" MDF and plane it. That effectively becomes my spoil board.
3- does the placement of the extrusion make sense? should I add more?
