    You may get a better response if you provide full tolerances on the drawing - nothing says 'run a mile' to a company looking for a straightforward job like an untoleranced drawing.

    Also you need to specify what material they are to be made in, and give an indication of quantity reqd...

    BTW most machinists would find "Please ensure all dimensions are correct' on the drawing either insulting or exceedingly amusing :-)

    (Edit - sorry, that sounded a bit smartarse. Just that making things to the dimensions given (within tolerance) is what machinists do if they want to get paid...)

    Ok the drawings were just to give an indication of what i was talking about.

    When i talked to companies about it they have been a bit aprehensive because its just a one off job, as i just want one of each. They are to be produced in 6082 T6.

    The please ensure all dimensions are correct bit was just my mate, asking me to check the drawings before he went any further with them, not me issuing an instruction to an interested party lol.

    In terms of tollerances, i'm new to this game the major dimensions can be +/- 0.5mm and i specified the bearing fit.

    Cheers
