First design - Few questions

[EddyCurrent]

If it's any help I made my machine with woodworking tools (other than the welder for the frame), bandsaw (standard wood blades cut aluminium), router and standard carbide cutters for wood (cut aluminium okay, just use small cut depths), bench drill, small angle grinder with metal cutting discs, sabre saw with metal cutting blades, disc sander. Then the usual hand tools such as files, hacksaw, etc.
