Required to be soundly worked with the hands (6)
I believe the answer is:
needed
'required' is the definition.
('need' can be a synonym of 'require')
'be soundly worked with the hands' is the wordplay.
I cannot quite see how this works, but
'be' could be 'need' (needing is a kind of being) and 'need' is located in the answer.
The remaining letters 'ed' is a valid word which might be clued in a way I don't understand.
This may be the basis of the clue (or it may be nonsense).
'to' acts as a link.
Can you help me to learn more?
(Other definitions for needed that I've seen before include "Was in want of" , "Missing" , "'Wanted, required (6)'" , "Required; sounds like worked (dough)" , "Required, necessary" .)
