Hi all, first post from a routing newbie. I have a tricky job to do and am looking for advice from the experts.
I have a pair of speaker cabinets that ive had cnc cut from 21mm birch plywood. Ive now glued them up and done the first pass of sanding. At some point soon i need to rout speaker openings in the stacked side of the cabinets.
These will be recessed drivers, so the front edge of the cut needs to be clean as a whistle. Ive had a stainless steel circle jig fabricated for my cheap palm router with plunge base.
Hole needs to be 14 cm dia. down to 1cm depth, then an inner hole of 12 cm dia. all the way through 20mm
Im looking for advice on the best method and bits to use. I figure all the experts are here! Ive already been advised on a spiral downcut bit for the edge, and one person said an o-flute will give the cleanest edge. (brands whiteside and freud suggested) Local carpenter when asked for a quote said he wouldnt touch the job with a bargepole.
Ive attached images showing the cabinets, the circle jig, the internal cabinet structure, and a 3d model showing the hole placement.
Any advice greatly appreciated, im a noob, and these cabinets are basically irreplaceable. 😕
