Kondia FV-1 Head disassembly

[PixMan]

I got a couple hours in the shop today, raining all day so no lost seat time on me motorbike.

I counterbored the holes for the M6x1 mounting screws, milled away the top surface to the correct heights for the feed engagement/disengagement lever and the 38mm counterbore for whatever they call that black round thing used to support the forward/neutral/reverse rod. Of course you can see where the 2-flute 7/16" solid carbide end mill I used for milling the counterbore overcut on the plunge. My machine's limitations are part of it, because the hole milling cycle moves to the outside first, you plunge to depth and them it mills with an inward spiral. Sorry about that, but it won't be seen after assembly.




I used corner rounding cutters to try and get the profiles somewhat like the print, but without a 3-axis control and 3-D modeling CAM system it's not possible to duplicate a casting's smooth blends and contours. I'm still going to try and get some of the 1.5mm corner radius going around the 25mm radius and into the angles from the 60mm width to the 25mm radius. My machine's control was spitting back error codes, so I'll try again tomorrow or Sunday.

When I get that done I can then make a 14mm pin to slide into the bore I'm using as a datum (most dimensions are taken from the center of it.) With a pin in that bore I can flip it 90º and get the 16mm bore rough drilled and a starter bore done to guide the 16mm reamer that's on its way to me. I'll mill the 6mm wide slot for the lever and then ream the 16mm bore.
