Review: Well Made, Good Quality and Router Fit. - The Jasper 240 PRO works great, with perfect circles with no tear out or unevenness. Just be sure and take your time and route out small amounts each rotation rather than attempting to make one deep rotation. This tool is easy to use however is made for those who are familiar with woodworking tools and routers, so for those new to routers be patient and don't force anything, study the included template. This tool works very well.
Review: Initail thoughts on use, - I am using a DW625 plunge router, I bought this because I need to create holes of non standard diameters less than 4 " in circle cutout templates. Most other circle cutting jigs do not go less than 3-4 inches. Overall very good jig. Very glad I bought it. Some notes. 1) I struggled to match the 2 holes on the 240 jig to the base of the DW625, as the bolt diagram provided did not list the DW625 specifically. However, since there were only two bolt holes for all DeWalts I guessed those were it, However note - the rounded edge of the jig does not match up to the rounded edge of the DW625 - it is rounded edge of jig to flat side of DW625 base. 2) Non-intuitive so beware - the scale side of the jig goes face down to work piece. This is because the screw bevels are on the scale side, so to make the jig perfectly flat on bottom the bevels need to be on the work piece side. To get the jig and router into the correct circle diameter pin hole you need to count rows and columns. Not a show stopper, but quite surprising. I even looked at several Jasper videos and photos to confirm this is how it is used. 3) Number 2 above may due to the placement of the holes from 1-4 inches, which can be covered by the router base. So it is not easy to get the jig set in these pin positions, but can be done with some time and by feel. 4) How to use the centering jig for the 240 jig when attaching to the router is kinda of funky. There are two pins on it, but it is not intuitive which holes in the 240 jig they go into. Lining up the picture of the 240 router bit opening did not give any hints to which holes the centering jig would go into. It was weird in that I could not find the correct holes by experimenting until I inserted the 1/4 in alignment pin (provided) into the centering jig then the centering jig suddenly went into 1 1/16 and 1 3/16 pin holes. I had tried those without the pin insert to no avail. This indicates an incredibly tight fit. Which very nice, Just don't waste time like I did!. My first hole was cut at 3 3/4 in HDF. Measuring afterward on outside diameter of the hole (not the resulting cut out circle) was 3.7490 to 3.7505. The second hole was set to 3 13/16. The outside diameter measured at 3.8055 to 3.8090 around. The resulting cutout circle in my use was 0.5 in +/- less than scale value. So if you need to have the cut out part of the circle be a given diameter it looks like the scale value selected needs to be 2x the 1/4 inch bit diameter higher. Again very glad I got this and recommend to anyone cutting smaller circles.

### ⭐⭐⭐⭐⭐ Perfect circles
*by B***B on February 27, 2025*

This thing worked great on my dewalt 618. Easy setup and makes cutting a perfect circle easy. Only thing I'd do different was I'd order the kit next time with the case and a few extra goodies.
