Just a few more comments on the Mark five. If you can cut a quality stone on that machine you can probably do pretty good using a wooden stick and a post. While that it is possible to do so and I have done so many times, it is very tedious and time-consuming. So if I ever get my Mark five machine back from graves I will certainly entertain offers. I have made my own machine which is very accurate, a lot simpler and easier to use and a whole lot cheaper!
