mini drill press
grabcad
-a miniature drill press, I designed in order to minimize the cost without sacrificing much of the function.-it's compatible w\100W(actual 47) universal sewing machine motor,629zz ball bearing,M10 fine thread shaft & 10mm chuck-total cost $20, this may vary due to pricing experiments showed results of drilling holesup to 18mm in wood,8mm in AL,4mm in construction steel.-the clearance between the slider assembly and the pillars (0.2 in the files) should be adjusted depending on the LASER cutter machine.-the M10 fine thread bolt will be industrial made, which means it's OD would be around 9.5mm, this will need some filing before assembly.
