Pipe clay is sorting me out. Soon I will have a runout free chuck that will not be called every name under the sun. Haha

I've started making a pitkin donut for my lathe, which helps support the compound. I started with a 4inch diameter piece of aluminum. I had to max out the jaws all the way to get it to fit on the inside teeth, i tried using the outside teeth but they hit the center of the chuck before it closed in on the material.
I had to actually remove my safety shield because the jaws protruded slightly out of the chuck and was fouling. It also limited how much adjustment i could make to get the work centered, which i managed to do, but was difficult.


By looking at the jaws, it would have really benefited if there was a tooth in between the teeth to hold this size item. is there somewhere i can buy some shorter teeth that will give me more or less travel, or is the solution to buy a new medium sized chuck.

I'll be making a ball turner soon and will be working with the same size diameter stock.


Cheers

ps. I know you guys like pics. I always try and include one.

You could always try my soft jaws trick.

I would be wary asking them to hold such a large work piece without some kind of additional support...
However, they were made by parting off three slices from a scrap alloy belt gear. They need to be at least as thick as the depth of the tooth they are intended to fit over. In mine I drilled them with a 16 mm hole a little off centre and then cross drilled and threaded 2 BA. The grub screws are short lengths cut from a long bolt and a hacksaw cut across one end for a screwdriver to fit. Use what ever suits you. I then clamped a suitable sized disc behind them tightened the chuck jaws onto it, then I fitted the soft jaws securely and then turned them to suit the work. A gear in my case, so didn't damage the teeth. Remove the disc from behind and then clamp your work piece. As you can see from the picture I only cut deep enough to support the gear. Actually I did two gears, you can see the second face just outside the first. You could go all the way through and you could set the work piece onto the chuck face.

HTH.
