Title: How to achieve this curve?
Post by: GSXRMovistar on November 04, 2014, 03:41:16 pm
Hi there, I've mocked up a cabinet design in sketch-up I'm considering attempting and all seem straight forward for the exception of one curve. Below is a cross section view of where the controls will be mounted, the 'B' curve will be a chamfer using a router but I can't figure how best to create the 'A' curve. Any ideas?

Thanks. :)

Sure you don't want to simply use a round over bit instead of a chamfer bit on B?

As for A....how about forming a strip to glue on afterward via router/table?  Or am I envisioning this from the wrong "angle"?

Lots of wood putty and sanding. Or see Spoot's suggestion.

Yeah, that's be easy too.  Could take a large dowel or some pvc pipe etc to wrap the sandpaper around to keep the curve consistant.

I would personally just bend sheet metal and have a metal CPO. If you don't mind a ridge, then just get some cove trim and be done.

x2 on the dowel rod/pvc pipe. just finding the correct diameter for what you want would take some trial and error

This is what I did: Freehand routing and sanding afterwards to get the curve really smooth:

But thats for the end pieces which are only 15-18mm wide, I'm wanting to apply a similar curve to a piece which is 660mm wide.

Yeah, I don't think EMDB understood like the rest of us did.

Honestly, I've only ever seen that piece curved on a metal panel. None of the wood ones I've ever seen have a curve like that.
