In person the tires are real nice, The tread does not look goofy like some of the narrowed tires I have seen. Like always I am proud to have my parts on one of your builds. It is unreal the talent on this forum.
I have five CNC Sherlines they are good machines not the best money can buy but the best I can afford. The leadscrews they come with are not the greatest but there are good ones you can get for them. I rebuild every machine about every 150 hours or 4 weeks. You will have to learn how to run a manual mill and lathe before going to CNC or you will not know what to tell the machine to do. I would get some books and go on some websites before you buy anything. Have a good time machining can be a lot of fun.
