Well here goes... Aluminium frame router design

[CharlieRam]

I was thinking of going that way for the belts but it just seemed a bit unwieldy. Can you tell me why you think it will act like a tuning fork, have you made one like it before? Is it because I am using steel plate or is there another issue going on that i cant see?

One thing worth noting, at work we grind thin walled exotic alloys like inconel and waspaloy and they really do resonate whilst machining, we get around this by using a glorified elastic band and it reduces the vibration drastically which got me thinking about the rubber floor mats you can get for playgrounds. If I were to use strips of that glued to the metal plate in stategic positions then that should help with dampening if that is the issue, What do you think?

I have made many Z axis but only ounce did I build one this way and that was due existing design issues(not my design), it was for a machine which exclusively cut HDPE so no big deal but the difference between my normal conventional way was clear when pushed hard.

The differnece between this and your work example is that the work machine didn't vibrate the material did which happens now imagine what would happen to finish if the tool was vibrating as well.! . . How do you stop or deal with that.? . . . . . Cut slower/shallower point being your making compromises you shouldn't have too just becasue of machine design
