Router cutters - less that 1/4 circle round-over ?

[aesmith]

Probably not clear on the previous picture, but tilting the cutter or the work to avoid over cutting in the middle, simply means it cuts into the bottom of the work instead.

It's a simple physical fact - you can't cut a convex arc of 60 degrees, using a 90 degree round-over.

No it doesn't. If you lower the centre point of the lower arc it won't.

There we are then - answered your own question.

When you reach the practical limits of your router cutter catalogue and ingenuity it's time to buy a spindle moulder :lol:

I notice the TITMAN from the General Chat forum hasn't joined in to give his 'advice'.

He is missing an ideal opportunity to contribute in a genuine way.

This would be something that we would need more information about, more sizes radii total high dia etc or even a wood sample.

It seems that you are after an ellipse rather than a full radius (ie a grecian ogee rather than a roman ogee) on page 45 of our catalogue

spindle moulders are also an option if you have to machinery. page 154 of our catalogue

If these are not the sizes you require we could (as could other router manufacturers) manufacture a bespoke tool.

I hope this is of help
