I have had a 6X26 for about four years now and I am very satisfied with it, after making several mods. I think the main reason these mills are not as popular as they should be is because of the, as delivered, rather small work envelope, compared to table size. I have a Harbor freight model, the cheapest available in the United States. As delivered the X=15", Y=6 1/2" and Z=12". The current envelope is: X=20 5/8", Y=8 3/4" and Z=18" with a 6" riser added. I believe I could have extended the X travel to 22" in hind sight but I have had no need for the travel I have now. The Y mod was the best choice as it allows me to machine an edge of the table, something you can't do as the mill is delivered. . I have some pictures on the Yahoo groups that show how the mods were done. I have also added 3 phase/VFD drive system, 3 axis DRO, X power feed and a "tachulator" that can show SFM- a real end mill saver. With all of the mods I have less than $3,000 US invested.
