Howdy fellow metalbashers,
I have a question about woodruff keys.
My Bridgeport needs a new #3 Woodruff key (so says the manual) in its
quill housing, as the old one is disintegrating.
I could fairly easily make one, except that there's no such thing as a
"#3" in my Machinery's Handbook...
Does anyone know what size a "#3 Woodruff key" is, so I can knock one up
before my quill lets go?
Oh, also... has anyone changed the quill balance spring in a J-head; and
if so, how does one go about making sure the spring goes onto the shaft
correctly? It looks like a shaft out job to me, but the manual seems to
suggest you just stick it in there & turn, and all will be well...
I make my own as im out of spares and to go and get some takeslonger
take a high tensile bolt , chuck it in the lathe
turn say 1/2in to the woodruff key dia.
cut it down the bolt end, then cut off the thickness of the key slot.
about 15mins work. file up to fit.
hope this helps.
