Well... it's been a long time since I've machined (mid 70's)... but a couple things I recall:
* Always make sure the bit is entering the work with the flutes spinning the correct direction. (i.e. You want the flutes to be rotating in a manner they resist the material and not grab it.) * If the flutes are loading with material, it will try to do what you're describing. (Lift, draw the work in, etc.) I recall for precise work required higher bit speed and very small increments of feed. Best of luck. You dedication level is amazing.

It is just so much easier to do now that the mill is at my house. It has spent the previous 6 + years I owned it at 2 locations with very limited access. It is interesting how in the clip it looks like the bit is going counter clockwise bit it is not. What is ever stranger is when the bit somehow sucks the car upward and out of the fixture to go chomping away. That happened twice yesterday. By the time you think there is a problem the mangling is done. That really puts the chomped car back in the 'to be fixed" on another day pile. If you think you want to try your hand at importing brass trains watch this clip continuously until you change your mind! This is just one day in the life of 12+ YEARS of trying to get these cars fixed enough to use. I have fixed, painted, stripped, decaled, machined and fixed again MANY cars all because I wanted a X29. You guys that get good models with nothing to fix right out of the box don't know the fun you are missing! This brings modeling and "brass bashing" to an industrial level!
