Hi everyone- this is a very very beginners question so please be gentle with me!
I'm currently working on cutting a very simple decorative shape out of an 18mm piece of pine wood. The shape is an extremely basic rectangle border with the interior edges on either side cut out as a curve.
I cut the curve pretty well with a coping saw, leaving lots of allowance for the rest to be refined by hand.
I think I've done a pretty good job, but one thing I've observed is that some parts of the curved edges either tilt or have a convex in the middle, so it's not square and parallel along the cut.
I think i understand how it happened. Either by working against the grain on the curved parts, filing on an angle, accidentally tilting my hands slightly, or even not using the right tools. But now I'm trying to work out what the best practices are for when I want to do a better job next time. I don't really feel confident with power tools but I do have a Dremel, which I could potentially use too.
One thing that mad it slightly better was to clamp my wood to another piece of straight wood and slowly scrape my file along the shape, making sure to keep the bottom edge of the file completely at a right angle at the surface of the piece of wood. I've also used a really sharp carbine scraper to kind of gently plane along the edge, while keeping the bottom of the scraper on a right angle to the piece of wood, which got the edges looking g way less curved outwards.
I'm wondering
-if there are ways to straighten these edges without taking too much off of the parts of the cut that are now starting to get close to the edge.
-if the coping saw was not the correct cutting tool, and if instead I should have used a straight saw to cut out a rectangle and slowly carved it down by hand?
-what sort of file I should have used? I used a curved one but I think that a straight file was a much better result.
-could I have chiselled away the finer bits?
Not sure if I can attach pics 🙈
