Okay.

The picture shows it all.

This piece is from the turn of the 20th century, and I’m providence says it was hand-made. Without delving totally into the likelihood of each piece, including cast iron, was made by hand and not recycled, how would the inside curves (coves?) been cut using hand tools only?

It’s a question I’ve had for a while.

Even the Studley chest has inside coves.

Any ideas?

Maybe a wooden plane made for the specific application?

It’d have no sole! :-)

The straight sides with coves, yeah, But the others?

It takes 30 min to carve them out, roughfully; and then with scraper card with that profile mounted in a wooden gig, that would finish the job.

An interesting question, Smitty.
The first (and only) thing that comes to mind is a convex spokeshave.

You could use one of these as long as all you curves were always the same radius

But carve and scrape works too

Wow, curve and scrape sure seems hard. Maybe the invention of routers was a good thing… :-)

I you have a selection of gouges, it’s not too hard.

If you really want to be intimidated, consider a pie crust

Smitty, I would use a round molding plane in conjunction with a fillester plane for the straight edges which would be pretty quick and then use an appropriately sized gouge to make the curved sides join the straight sides. Yeah, it would take longer with those tools compared to a router, but for those of us without a router, that would be the way to go.

Use a round bottomed Squirrel tail plane.

Use a router Smitty with a bearing guided cove bit. You’ve already got a mountain of galoot points in the bank as far as we’re concerned. Power tools are better for some things. Just sayin’.

Make the scraper Smitty, then rout it. Lay a gouge of the appropriate size on the bench alongside your work and take a photo of yourself pretending to scrape it. In this way, the flow of galootness will be preserved in your blog without it taking very long to do. I won’t tell anyone if you don’t. :o)
