And..... You have one sitting right there *starts to dial homeland security* :p
 
I mounted a new six inch three jaw chuck to my old back plate.
Had to make a sleeve that was heated and dropped on too the old journal. Then machined down to fit.
Then took the cross slide off to figure out the binding issue I'm having.
I think it is the key that slides in the slot of the lead screw.
Ever thing else looks good?
 
Am starting to get the hang of drilling using the small lathe (Hercus 9") - go steady - clear the hole regularly - use cutting oil.

Needed to drill a 1/4" hole through 13.5" of black bar - had to go half way from each end and was absolutely chuffed when they met in the middle. Am able to slide a 1/4" rod all the way through and not feel any "step"

Got the rough bar between centres initially to turn it parallel and cylindrical.

Wrapped one end in kitchen paper and stuffed it through the headstock so that the loose end wouldnt rattle around inside the headstock bore - and gripped the other end in the chuck.

Centre drill - then 1/8" x 2"- then 3/16" x 2"- then 1/4" x 6 3/4" - lucky I happened to have an extra long 1/4" drill - approx 1/4" "pecks" and clear the flutes each time - didnt take very long - was quite surprised.

After a few inches of drilling, loosened the chuck and advanced the workpiece so that the drill was always drilling through the part gripped in the chuck jaws.

After 6 3/4" turn the workpiece end for end.

Gently honed the 1/4" drill by hand with a diamond plate before using it.

Am truly astonished that it was possible to do this - I guess in 5 years time I will take it for granted, I dont think I could have done that with a piece of wood when I was interested in woodwork.

Is it simply the nature of the lathe that the holes drill straight down the middle without deviating ?
