Harrison L5 lathe rebuild

[Micktoon]

I have managed to do a bit more of the electric box mounting today. I am making it out of what I have rather than what I would use in an ideal world so its a bit more robust than needed but at least it will not fall off :thumbup: The overall plan is to have a rear alloy plate to which will mount the inverter , a die cast alloy box to house the switch gear and transformer for the lo-volt lamp, along with a red three phase socket ( this will be used for the out-put of the inverter going to the lathe motor but will also mean other things could be plugged into the socket (chop saw)or three phase motors tested by plugging into the socket too) I have also decided to make the top of the vertical plate have a horizontal shelf to stop any debris going into the inverter top vents, this shelf will be edged with alloy angle and will do for storing dial indicator s etc.

This is the two bits of 5mm thick alloy plate I have lying about. Due to the large bit only being an inch bigger than ideal I decided to leave it this size.



It will go roughly like this photo and have the shelf along the top edge, you can just see the markings where the inverter will go on the left side and the box on the right side at the top below it will go the legend plate for the lathe speeds. I have placed the clutch and gear levers back into position just to make sure everything has room to operate.



This is the bracket it will mount to that is bolted to the rear of the headstock casing.



The rear frame cut and clamped ready for welding, again just made from what I had about.



Welded up and clamped into position, this frame might get bolted to the headstock angle bracket but due casing not being flat it sits slightly off vertical so I might hold it into position and weld it to the angle bracket.



I will either use these holes to bolt through or plug weld them to the angle bracket if it needs to become 'one part' to compensate for the rear plate not sitting vertical.



Cheers Mick.
