I use mine for curves. I have one with a rounded sole, so have the option to do both convex and concave curves. I also use mine to take the edge of sharp corners sometimes.
Ah, a Big Question. Almost easier to say when not to use them in a way. Shaping is their forte. Whether it's cleaning up curved edge of a component, like this tale of woe rescued by spokeshaves, to forming and refining more complicated curves, such as:
To chamfering:
To turning square sticks into rounds:
Marvellous tools, horribly under-rated and plagued by the fixation for fine shavings.
I got a low angle spoke shave for christmas ...... not had time to use it properly yet (DIY getting in the way just fixing a damp problem)
But I made a nice pile of shavings on Christmas day giving a scrap plank a nice flowing curve ......... unfortunately I did it in my Mother living room
Yes probably I seem to find it gouges out a furrow ruining the piece (So far on scrap wood as I am practicing with it atm)
Perhaps I am taking too much off you see Iam trying to square timber with it and sizing wood to what I will want. But I must stress only on scrap wood until I get the hang of it.
Like most tools I am practicing planing and finishing sawing etc until I feel more confident. This is the best way to practice new techniques joints etc?
