I'd forgotten that I fitted an angle iron frame all around the base, maybe I'm dreaming about a length of support coming with the wheel kit or more likely I used it for something else, it was a long time ago!
you can see the metal lifter bracket the top of which is 160mm from floor level however the saw sits almost 30mm off the floor on loose packers to level it as my garage floor is sloped otherwise would be about 130mm.
At its' working height I need to put a board under the lifter wheels, take out the packers, drop the saw to the floor, remove board under lifter wheels after which I can easily move it around.
Poor pic just taken in the dark on my phone but you'll see what I mean.
