The W&B Barber's Ratler is ready as well. I'll send that one together with 2 DA's. We'll deal with the Tally-Ho later. I have to think that one through a bit better. I need to hone up the DA's for you, but I'll make it a priority.torbenbp said:Ohhh by the way...Would it be very unconviniet for you to send the 2 DA`s? Know the agreement was to send them all together.....
Bart said:Excellent, my friend. I was thinking in that direction, yet I believe I will first create a small chamfer on one edge of the wheel.
I think it's safer to avoid serious unevenness (at least in my inexperienced non-Sheffield-grinder's hands:-/ ). And I can just could just leave the chamfer in place for future adventures. The only thing, I'm currently trying to fold my brain around, is the question whether a rotating 45 degree chamfer of 5mm on a 200mm round wheel would behave significantly different than a 5mm wide wheel with a 200mm diameter. I do believe it would alter the resulting diameter. I would be working on part of an imaginary cone, which makes the curve significantly flatter. If I for instance would make the chamfer almost 90°, I could end up with an almost dead flat curve. I have no clue how much wider the curve becomes at 45°, but it is clear to me that I must maintain a fixed angle, since the curve will vary with the amount of tilt I apply. That makes me doubt about a rocking motion. If I work on a flat chamfer, it will be easier to maintain that fixed angle. 45° is probably too much. I was trying to figure out how much. While I 'm at it, I must also consider chamfering one of the smaller diameter grinding wheels I have for my jewelers lathe. I was thinking of doing a Google search for a mathematical formula that calculates the "virtual" curve of a cone cross-section with diameter x and angle y. If I find it, I can make an educated decision on which wheel to prep with which chamfer.
