Delivery took a month. Does the job what it was meant to be.As it weights 1.7kg and makes chuck to lean more out, it makes some hard time on spindle bearings. Bettet solusion will be to drill 4 new holes into lathe spindle flange and mount 4jaw chuck without that adapter. But that operation takes some skils to be done rightly. As quick fix for newbie as me, that adapter plate is OK.
thanks
