An old work friend ask if I could do a little job for him, but the job needs a 4 " length of 4.5 mm dia bar all I've got is 3/16".
But with this bit of kit skimming the bar down is a synch.
I picked it up from Chornos a few years ago and found it very handy.
First make a brass bush the same dia as the starting bar in this case 3/16
Then turn a short length of the bar down to the required dia 4.5 mm
Then use this as a set piece to set the tool on dia.
Then with just a short length sticking out of the chuck, use this to centre and square the steady.
Then wind the tool away from the chuck and pull the bar out and insert the end into the bush.
With just a spot of oil on the bush start the machine enguage feed and reduce the dia of the bar.
Thats it job done in about 10 min.
