Rounding the profile of a box

Recommended Posts

How would you guys achieve this "round" profile? that is, if you look straight at the front of the box, you won't see a rectangle with 4 straight sides, but rather the left and right sides of the rectangle are rounded. If the short sides are short enough, it could probably just be done on a bandsaw, but the long sides would most likely be too large for that method. Any other suggestions?

 

Thanks,

David

Bandsaw to rough it out. Spokeshave to smooth out the saw marks. Shaped caul of the corresponding radius with self adhesive sandpaper to fInesse the radius and ensure linearity.

Paper glue four chunks. Turn a round. Separate the paper lines. Oh wait, I don't own a lathe. It is something I would consider though.

Its hard to tell exact dimensions, but I'd guess that profile to be somewhere between 3 and 5" tall. PB's recommendation to use a shaper is certainly the simplest, if you have access to one. If not, I would follow Eric's advice. Make several passes over the table saw, tilting the blade a little farther from 90* each pass, to approximate the curve. Then "fair the curve" with a plane or scraper to form the rounded profile.

Woodsmith Magazine presented something similar a few years back. Same method that Eric mentioned. Attached is the relevant portion of the article.
