Hey, when you cut your parts out from the interior of the bar like that, are you leaving some material at the bottom of the slot to hold it in? Kinda looked like it in those photos. How much do you leave if so and how do you then remove it? I ask because I have done a few things that didn't work too good. Skimming away the back caused it to chatter like mad, leaving in holding tabs made for really hard to remove blemishes on the sides, but I don't trust a big part to drop out without jamming up or bouncing at the end and gouging.
