During my short term on machining in the apprentice school i was only familiar with mild steel soft jaws to be machined as required to suit a particular work piece.However after a couple of hours in the shed i have almost finished a chuck adaptor plt I used whatever materials i had to hand and...

After a couple of hrs in the shed.The hard jaw i removed was fairly soft and drilled/tapped easily so finished the new soft jaw and finished it.Easy Peasy. HOWEVER when i checked the 2 remaining original jaws they were pot hard so i had to have a rethink.I finished the other 2 soft jaws and...

I cant remember the exact size but i did turn the 3 inside concentrics to a larger dia as they are not doing anything and i thought it better to leave them heavier for strength.No fixed rules just do what looks/feels right From memory 3/4" seems a bit large.If the big end eccs are 1/2" or so...

The jaws are solid mild steel with the intension of just unbolting them.If tapping is a no no then alternatives will be to grub screw clamp from the sides or even stitch weld as a last reort.Just going out to the shed now to do a little more

Thanks for all the input Guys. I have seen the common method of making bolt on pieces for the jaws but wanted to make full soft jaws without having to cut the spiral teeth. Just finding a use for this oddball chuck without letting it go for nothing.Time will tell if i can drill and tap the jaws...

I have wanted soft jaws on a no of occations but they are difficult/expensive to buy and cutting the spiral teeth are beyond me.With buying the 3 myford lathes and restoring i have collected a no accessories etc,one of which was a 5" 3 jaw chuck with no adaptor plate and only outside jaws.I had...

I agree that sq bar with slight rad cnrs and small imperfections would add to the look

like the lathe

I agree,but would use a 4 jaw self centering chuck and hot rolled sq stock depending on availabilty and size What is the head size. Keep it simple,these alternative ideas would probably work but take as least as long If a std thread size screw is available can an available and suitable head be...

Still waiting to sell Myford no 2 and hopefully try to find a suitable Super 7.Weather has been bad so have not been doing much Reading Norms posts about an adaptor plt to fit the Sieg with a Myford nose,i was unsure of the benefits.However looking for a small project,having the materials and...

There will be some force at the bottom of the bush opposite the teeth but none to the sides.Would brass be better ?

4 jaw self centering chuck are readily available.I bought one when making the turners cubes and now use it all the time.Holds sq and round, use 3 jaw for hex and round

Still following with awe

I can see them now,look good especially the brassing Keep em coming

very nice

I use a lot of cheap RCTs and the main problem is chipping rather than wear.However i will stick with them as i have no comparison with more expensive named ones. I also get a certain extended life by

I worked in our foundry for a few weeks and boy was that a dirty job.Only thing worse was the fettling shop where the risers and pourrers etc were knocked off and the raw castings were rough fettled with hand held angle grinders etc The castings were then sent to the finish fettling dept to be...
