Any idea how long it would take it to make one of those
They make nice show pieces but you wouldn't want the bill for making one. EDM'ing any of those would be a v-e-r-y slow process I reckon.
I can bet the first person I showed it to would drop it on my quarry tiles and chip it
Mr jo blocks managed to produce better than micron precision at almost production speeds. Nothing primitive about that, he changed the engineering world forever.Certainly makes Johansen gauge blocks look a bit primitive.
