My axminster was the bottom slider and that what I had to do I don't know the new design. That was good and did last a few years then just burnt out. It the newer design, well they are all different from mine as the sliding mechanism is higher. So really suggest you phone the SIP people or Toolstation as they are both helpfull. I have and thats was part of my research asking questions. But what you say is interesting as its something I have always done and hadn't thought about. Will let you know when I set it up as it is arriving today and depending how I feel as I live on morphine and severe pain. I will be setting it up by the end of tomorrow, then I will notice the difference in the way it cuts. I buy machinery to help me do the cutting as its difficult and painful. Mind you the health and safety would be having fits as I am using machinery on very heavy doses of morphine.
