I have all three in all different shapes and sizes, presses vices and hammers..up to a 50 ton press, a 50 kilo vice and up to a 15 kilo sledge hammer.Igor, actually the press does not control more than a vise, but more than a hammer.
That is pretty close, I tend to think of a Kilo bag of sugar in UK as being about the size of the 2lb bag we used to get before we were force fed Kilos etc. Trouble is my mind still thinks Pounds, Ounces and Tons plus Pounds, Shillings and Pennies.In pounds you must double the numbers? right? in the imperial system i must calculate, i will do this tomorrow for you.
With best regards Igor
