On a side note, i have had this type of thing happen a load of times with different sellers. I've complained to ebay and they always came down on the side of the seller. Do you think it has some thing to do with the income they generate:whistling:

After the auction ended the seller cancelled the sale

cheers for the heads up ian

Hi, why not phone or ask via our contact page, as manufacturers / cnc component stockist's we do our best to answer using our build experiance!

The graph: Trapezoidal 12mm Diameter / Length shows 4000mm @ 100rpm up to 1000mm @ 1500rpm

TR12 *1200mm = 900rpm
