Any tips on what I can use, it has to take 3,2mm (1/8") tools to be suitable.
I don't have equipments to measure the runout, but as I could see it with my naked eye I'm guessing it is close to 0,5mm. Might work for some of the simpler PCB designs with no surface mounts, but I don't want the spindle to be my limiting factor. I'm guessing the roller bearing design might end up as the limiting factor? |
the cnconabudget spindle will give you much finer pitch pcb traces over a dremel.
