    King 1440 and Craftex Threading

    Just to add a thought using the information provided. If the use of a combined 127T/120T provides a speed reduction from 100 RPM to 94.485 RPM, that means that the given metric values shoud be INCREASED by 5.8% (1/.94485) to match the imperial setup with only an idler gear. Using this...

    King 1440 and Craftex Threading

    OK guys, here's a little hands on, chuck turning values mesured on my actual machine: Comparing these values to the ones that are on the plate of the change gear cover, here are the metric to imperial converted values: GEAR COMBO: 40T - 127T/120T - 40T As far as I'm concerned, the values...

    King 1440 and Craftex Threading

    My questionning is that the side plate chart uses the 120T/127T gear while the front chart just uses the 127T gear as an idler. Will this influence the feed rates obtained on the carriage? So if I put my levers in the E1 position, the longitudinal feed on the plate states 0.134mm (0.0053 in)...

    King 1440 and Craftex Threading

    I'm talking about the linear feeds, not the threading. The only available information is on the side plate with the metric values specified.

    Does this mean that I need to build a spreedsheet to find the correct feeds with my imperial lead screw?

    King 1440 and Craftex Threading

    Hi all ... just to add to the confusion, maybe someon can explain to me ... I have an old King Canada 1440B lathe and the front plate has the following information: But on the side cover where the change gears are, it has this plate on it: This machine was available with a metric (3mm...

    Craftex CX601 Spindle Control

    Since I'm on a roll, do you guys think it's possible to hook up the direction controls to Acorn via the relays (M03/M04)? Here's information from Franco's Youtube video on his PM-728 machine: Was wondering if leads to magnetic switch could be connected to the relays. Thanks !

    Craftex CX601 Spindle Control

    Final update - line from L2 to filter was disconnected somehow during my manipulations. Going thru each wire's continuity I found the faulty one. Luckily nothing blew up :). Removed the pot completely including lines to magnetic switch and filter. Now have spindle control from Acorn using the F-...
