Standard Speed, If You Please...
The component parts of the (as yet putative) motor speed control for the lathe. On Joe's advice I've opted to try that avenue before going down the mechanical route and swapping motor pulleys out. I Amazon'd a cheap motor control/dimmer unit last night and it arrived this morning. The project box will be the old computer mains conditioner/spike suppressor seen here: I'll just strip out the filter and effectively replace it with the controller board you can see perched on the corner of the box.
Now to my old [fashioned] eyes the thing looks mighty puny, even though my motor's current draw (including startup surge) is well within it's quoted spec, and I suspect a plume of blue smoke and the acrid stench of burnt circuit board to be the most likely outcome, but we'll see. I suspect being a cheapskate is going to prove to be folly though, somehow. Keep you posted.
I bet you a pint that the "blue plume" will not appear.We both have a gestalt connection with motor controllers from "twiddling-the-rheostat-for-lip-synch" for all those months until the "Powers-that-be" Iain Dhall(sic) cobbled together a motor controller for an Asychronous motor that achieved a barely passable lip-synch. A problem which you nailed when you squared the time code reader output!! Lathe motor: NO contest for the Pros from Dover mate!!
