Yes that's the book I got & the one I was looking to use to build the machine, already know someone who has built this machine & that it worked so for me it is a good starting point, probably won't meet with some peoples approval but for me at least I know it can be done on a tight budget & it might be all that I ever need at the end of the day. If it isn't at least it will have given me something to keep me busy & should have taught me enough about cnc routers & their construction to have a much better idea what I need to do in order to build a machine that is suitable for anything I might need it for.
Although I won't be able to use all the parts again I should be able to make use of the most expensive parts like the electronics again so the actual wasted money if you want to look at it that way will be reasonably small.
