Hi Sjek - Looks good. make the gantry more of a box. Your columns are very stiff which is very good. You don't need so many cross boxes in the base. I've used the makita and its great but its very noisy. I suggest you look at 600W 48V DC spindle. Been a great upgrade to my machine and the cost is about the same (maybe less). I'd pick an ER11 collet as they are smaller (vs a ER17). I do deep things this may not be a concern for you. T10x15 belts require a much bigger idler then you have drawn. Get hold of a belt manual for this info. You will fatigue the belt quickly with such a small pulley and idler. It will be a very good machine, plywood is a great material. Use a good epoxy or urethane glue. Peter
