4' x 4' x 8" Router Build

That's good to know, I appreciate your input. I'll keep trawling through build logs and see what others have come up with.

Given what you have said do you think it would be better to have used torquier motors and gear them down to get the speed up, perhaps needing to go up in screw diameter as a consequence? I have no real concept of how fast is too fast / slow or how much torque is needed to cut at reasonable feeds. I have a combination of small fiddly and large uncomplicated projects that I'd like to be able to do on my machine. Initially I'm not that concerned about speed but at some point I would like to make some money out of this and so higher speed would be nice.

Does this look about the right amount of clearance with the z-axis at its lowest?



My plan is to have two pieces of wood for the bed, the top one being sacrificial. I've assumed the shortest cutter would stick out about 25mm and allowed this much clearance from the top of the first spoil board. This should allow for the top board to be resurfaced a few times and still give enough travel on the Z. Am I about right with this?

Cheers

Spindle looks ok but spindle plate would be better higher to give clearance for clamps or vice jaws. To still give enough travel the whole gantry then needs to be raised the same amount. But if you move it too high then the Z axis has to extend down further so it is all a balancing act in the design stage.
