To Tangent- My headtube holding set up for the flat plate was made by Alex Meade. The two towers were about .001" different heights! Close enough for horse shoes, nuclear bombs and bike frames. I placed a .002" shim under the taller side and a .003" one under the shorter's base. Here's a shot with it, note the whipping post is just looking on. It's thinking to it's self "who does that pretty thing think it is? All shinny and useless to do any real work?" Andy
