I purchased a record SC4 Chuck for my coronet herald, very pleased with it, secure holding and very easy to use.
Included is a thread insert relevant to your spindle size, you’ll need to select this when you order/select in a store.
(changing the insert allows the chuck to be used on lathes with different spindle sizes)
Can be used with lathe in reverse, just make sure fit the grub screw if you are going to use later in reverse.
I found I very soon wanted some smaller jaws, but apart from that, the SC4 has been money well spent.
