I was given this work-holding device with adjustable weights for working with out-of-balance pieces. Turns out there are (were?) other pieces available for off-and multi-axis turning, but the Kelton.co.nz site is not working. Are they still in business? Does anyone know if these parts are available from them or through any distributors? Or do you have one and have any comments?DSC_1355.jpgDSC_1356.jpg
