We are not aware of any other small chuck system offering a faceplate ring – but this is such a useful accessory we felt it was a must for this range too. It not only allows reasonable sized bowls to be shaped externally before being reversed and mounted in the standard jaw for hollowing out - it is great for projects that cannot be completed in one session and/or need remounting for any reason. It is held to the chuck using the standard 40 mm jaw set which comes with both the SC1 and SC2 Mini Chucks. It is virtually impossible to successfully re-chuck a timber spigot or recess as the wood itself will expand, contract or move over time but if fixed to a faceplate ring - that can be remounted any time on a suitable jaw and a project continued with ease.
