Hi Grant, I do not totally agree with you about the z axis depth stop as I have used it successfully in the past, however thanks for the info about the racking. I had a problem when machining a table top and couldn't understand the reason for it but now you mention racking it is clear to me what the problem was on my machine, Thanks again!! PS I have to agree about the legs, nice job man!!
