I just went to Rockler to get some African Blackwood to make pen blanks for making pens. While there I saw item below set up and running in there back room. To say the least I came up with a hair brained idea that im sure is nothing new. "Table saw shaft machine" Even though I have never seen one in person. This is a unit that replaces the left table wing extension of a table saw. Its a cross slide for a table saw. Could a person buy a second rip fence for this machine. Attach square tubing on side of fence, measuring corner to oppsite corner-both sides to make perfectly straight, more importantly, SQUARE. Do this for support only so that both fences will aways be square when slid across machine. Now make some small 2"x2" squars made of aluminum, drill and boar for a live spring loaded center, and some sort of drive center to drive blanks, attach to fence. Could offset tailstock end to desired taper. Buy a motor, maybe even speed control and make own shaft machine. This really looks like a peice of cake to do. I could even use some sort of bearing housing on the drive side. Heck could even give it indexing for making ring slots. You can get saw blade with kerfs from 1/16 to 2". I think I could make it all for less than $800 bucks. Is this a good or bad Idea. Thanks.
