Infinity Cutting Tools Professional Coping Sled
By Brad Holden
A good coping sled is a must for cope and stick routing.
A great coping sled is icing on the cake, and that’s what
Infinity has achieved with their industrial-quality Professional
Coping Sled. Hands down, it’s the nicest I’ve used.
A coping sled holds your work at a right angle to the
bit. When you’re routing tenons on the ends of a rail, for
example, you’d use a coping sled. The beefier it is, the better,
because routing end grain is tough work. Every feature
of the Professional sled is built on a large scale. It’s made
from 3/8" thick aluminum and weighs 8 lbs. Its base is 7"
wide, 11" long and will hold stock up to 6-1/2" wide.
Whoever designed Infinity’s sled must have coped a
lot of doors in a professional cabinet shop. The padded
handles are generously sized and angled just right. Coarse
abrasive paper on top of the sled keeps parts from slipping.
The sled has three extra-large toggle clamps. (I used
the two rear clamps to hold a backer board. This arrangement
makes it extremely easy to insert a new backer board
when I adjusted or changed a bit.) As far as I know, no
other coping sled has a three-clamp design.
Here’s one more unusual but brilliant feature: The sled
is equipped with a 3/8" thick Lexan guard plate that can
also be used as a bearing surface against your router table’s
fence. On most
sleds, the workpiece
board are all that
bear against the
fence. If both
pieces are narrow,
can be pretty
gives you a whopping
13" of bearing
The sled is pre-drilled for an optional miter bar. I like
using the miter bar on my router table, because it holds
the sled rock steady. I'll also use the sled and miter bar on
my tablesaw, to dado tenons.
