Making a Variable Speed Bench Grinder
Would putting one of those speed control switches typically used for routers
work on a 3450 rpm bench grinder. Looking for a way to make the rpm's slower. |

No. That sort of control needs a universal (brushed) motor, not an induction motor. Looking for a way to make the rpm's slower. Buy a half-speed (1400 rpm) motor. Same thing, but the way the windings are connected is different. Good for HSS turning tools, still too fast for bench tools Buy a geared-down slow, wet grinder. This is a _much_ more useful tool as it can sharpen nearly all woodworking edges. Prices for these grinders also range from the incredibly cheap upwards (quality to match, but a £30 machine is still useful) |
