Lynx Concave and Convex Scraper Sets

Exceptionally useful for anyone who works with mouldings and trimwork.


Lynx Concave and Convex Scraper Sets

Scrapers are exceptionally useful in the shop; they're a lot quicker to use than sandpaper, and, when properly polished and burnished, they produce a silky smooth surface ready for finishing.
These specialty scrapers are sold under the Lynx brand, which were made by the Garlick Saw Company (founded 1858) in Sheffield, England, until acquired by Thomas Flinn & Company in 1999. Thomas Flinn, who have been making saws since 1923, are the last UK company making traditional saws primarily by hand, so they should know a thing or two about working steel. Their premium line of Pax hand saws are carried by Lee Valley.

Convex set     

The Lynx scrapers come in two sets of two scrapers - a concave set for working beads, dowels and various concave mouldings, and a convex set for working flutes and convex shaped moulding.
Each scraper has five sizes - 1/4", 3/8", 1/2", 5/8" and 3/4" on one scraper and 7/8", 1", 1-1/8", 1-1/4" and 1-1/2" on the other scraper. These sizes cover a pretty wide range of the most common sizes used in woodworking. The sizes are exactly matched - the 1" convex for example, fits precisely with the 1" concave - ideal if you're fastidious about ensuring that same size moulding matches perfectly.

The scrapers are made of tempered steel and are nice and thick - a full 1/32" - so they won't flex in use. While you could use the scrapers as they are, they'll really benefit from a quick polishing (honing) and burnishing. The process is quite easy.
For polishing I wrap P1500 grit wet/dry silicon carbide sandpaper around dowels to fit the scraper sizes. The silicon carbide cuts very quickly, so polishing the edges takes only a few minutes. To burnish the scrapers I use the Veritas Carbide Burnisher; it's easy to use one-handed and has a  1/8" diameter rod. If you need more detail check out Liutaio Mottola's burnishing primer - it's on card scrapers but the technique is basically the same for these Lynx scrapers.

The scrapers are perfectly matched

For the price (under $14 a set, taxes in) these Lynx scrapers are exceptional value. They're particularly handy if you make chairs or stools and are super when it comes to cleaning up mouldings. Get them - use them!
