Cutting corners

You can cut it rough with a jigsaw then smooth it out and round it off using a sander (belt sander works best) This is what I have done in the past.

 

A router using a template is the best bet. Most worktop jigs have different radiuses for this reason. You can jigsaw it as John suggests. If you have very sharp chisels you can pare it to tidy it once the jigsaw has cut the bulk off or belt sand.

 

On the basis that help offered needs to be that which is simple and affordable............

A stanley knife following the curve of a plate down to about 2mm or so, to give the initial tidy corner. Then a fret saw (£5-10) to cut out the stock and abrasive to get the finish.

 

Router and make a jig mate.

 

Jigsaw you done. Then belt sander.

Mr. HandyAndy - Really

 

After using the jigsaw staple coarse sandpaper to a length of 3"x1" and sand it with a rocking action opposite to the curve.
I know what I mean but I can't explain it very well.

 

I know what you mean Chippie. When I was an apprentice,I heard it called "American filing". When you wanted to file a round surface, you actually rocked the file away from it. Seemed to work.

 

But if you had never heard of it could you work it out from my description. It does work though.

 

I think so Mate, but dead difficult to describe in words without a demo. Basically, for sanding/filing a convex surface, you file/sand as tough you are working on a concave surface.......Bloody impossible to describe in words !!!!

 

Yeah that's right, depending on what you have available ( usually with me is parting beading), just wrap a length in some abrasive and you have a lot more oomph to doing the sanding.
