Clamp Foot Plate

[Doddy]

A bit of thread revival, I'll admit. I've been playing in the shed trying to recover my old star mill back into operation (so many tales of woe, but that's water under the bridge now). Fitted with a 2.2kW Chinese water cooled spindle I thought to try a bit of isolation routing. Previously results for me were varied... from terrible to bloody terrible, and I'd written the technology off (I blame the previous 3020 style MD router that I had before). Anyway, this time the results were very encouraging - good enough for one-off prototypes of unexotic components. But, the one area of weakness is always getting the laminate flat on the bed. So, I'm here googling for "pressure feet" and up comes this thread. Has anyone in the last 5 years since this thread died come across an affordable pressure foot for a 80mm dia spindle, or knocked up a diy alternative? Any experience, good or bad of the results on PCB with fine (for routing... maybe 10 thoa) geometries.

Doddy,
In my pre cnc days I had and used a few engraving machines and on one I made a spring loaded nose cone for the spindle that worked very easy if you don't have a large qty' of units to make would be a simple option for you.
