Under "workshop techniques" section, I put a question relating to my proposed rope cutter. I was pleased to see a couple of suggestions regarding the plastic bushes but more importantly it was pointed out that I was proposing to use gauge plate whereas I needed to use stainless steel grade 316. It was also suggested " leaded"
So to look into this, I contacted the Stainless Steel Assn… I received a very prompt reply. The chap said that i should look to use a " Standard Duplex grade ss"Not sure what that is – Anyone used it before??
The chap then went on to say that perhaps I would do better using a Bronze Alloy. He pointed out that my propeller was made of the same stuff. Sure enough research shows that there are several grades of this & some are salt water resistant & excellent for this purpose ( rope cutters)
I do not have a price yet, but am asking if anyone has experience of machining this material. A bit more in cost may be better than buying a steel that my light mill cannot handle & I just wear out milling cutters by rubbing & vibration & not cutting due to lack of force etc
Any comments gratefully received
thanks
