I'm going to make a straight edge to use (in time) to scrape my lathe cross slide. I'm going basically copy what Baxtool did here: http://www.practicalmachinist.com/vb/metrology/making-straight-edge-214001/
Looks like Baxtool's pictures have been mangled by Photobucket, so I am reposting them
I got a piece of cast iron from McMaster years ago to do this and am finally getting around to it. It was a McMaster pn 8923K682. It's 2" x 1.5" x 24"
I don't know how long it will take me to finish, but I will post progress here.
Last night I milled the sawed edges. Just rough machining to make things smoother.
I looked at my lathe - the dovetails are 60 degrees. In retrospect, I should look at my mill's dovetails before I finalize the straightedge angle. I'm thinking 55 degrees, if the mill also has 60 degree dovetails. I don't have plans to scrape the mill, but I don't ever want to make this thing again.
I've taken Richard King's course and have scraped a bit, but never made a scraped part from scratch. Should be interesting...
