Review on Woodworking Tools Corner Quick-Jig Template for Router/Trimmer - R10, R15, R20, R25, R30, R35 by James Cruz

These are high quality phenolic resin (bakelite) outside radius jigs that come neatly packaged with foam inserts at an affordable price. The guides are very precise, easy to set up and ensure perfectly rounded corners every time. One of the main benefits of this design is the ability to attach it to a large work piece (e.g. a countertop) or use it on a router table for smaller jobs (requires a work piece at least 7/16 inch thick). There are six sizes. in this sentence: R10 = 0.3937 ≈ 3/8"R15 = 0.5906 ≈ 9/16" R20 = 0.7874 ≈ 3/4"R25 = 0.9843 ≈ 1" R30 = 1.1811 ≈ 1-3/16" R35 = 1.3780 ≈ 1-3/8" Unfortunately, R20 and R25 are the only two sizes that come close to those commonly used; the rest have somewhat "weird" radius sizes, which limits the general usefulness of this set, especially when dealing with existing rounded corners or patterns that require a standard. Therefore, the manufacturer must supply these gauges in imperial sizes or their metric equivalents in common sizes (R6 ≈ 1/4", R13 ≈ 1/2", etc.). Unless your application requires UK standard sizes, these templates should be at the top of your list.
