Errr, obviously I meant Inkscape.

Thanks for taking the time with this, though it's far beyond my capabilities with Gimp at the moment. I'll keep coming back to it as I learn more about Gimp, but at the moment my best bet is to try to make one from your last image. If I am successful, I'll come back with a photo of it. Thanks, Martin.

I'm not sure that it matters how many turns there are. A circular bowl I made recently had about 5 turns in a 10cm diameter, with a 5cm dia bottom. Allowing for width of cut, the spiral would be about 4mm wide. Thickness of wood was 16mm. Angle of cut depends on wood thickness and also blade thickne...

I suppose it would help if I explained what is intended with this. The idea is to make a bowls of different shapes, not just a heart. The idea is to cut along the line at an angle of somewhere around 4 to 7 degrees so that the spiral can be pushed down and lock on it's own taper to form a bowl or ba...

I replied to this on Saturday. I wonder if it got stuck in moderation somewhere. I don't want you two guys to think it was a post and run.

Thanks for the replies. Ragnar, I really ought to have stopped reading at the second line of your reply. My math education stopped at multiplication and division more than 50 years ago. Anything beyond that may as well be written in a foreign language. :D I downloaded the guides, so if you hear a ba...

Hi, I am fairly new to Inkscape and I am using it to create and alter patterns for scroll sawing. I want to create a spiral inside a shape, such as a heart, where the spiral takes the same shape. Something like the rough drawing below. Is there an easy way to do this?
Thanks,
Martin.
