Ridgid R2400 Router

I have made Christmas presents for this year, so now it’s time for some upgrades to my CNC machine. The first upgrade is to replace my poor Dremel with a small router.

Small palm routers or laminate routers are typically around 3lb in weight, which is small enough to fit on my hobby CNC machine. I liked the DeWalt laminate trimmer, but it doesn’t have variable speed built in. Next choice was the Bosch Colt, but I have heard some stories of how several hours of use can melt the plastic around the bearings, ruining them. My final selection was the Ridgid R2400 laminate router. Nothing but praise and easy to mount.

Note that the R2401 is quite different (and heavier) than the R2400. It seems that places like Home Depot and Lowes now stock the R2401 instead of the R2400.

A big reason for replacing the Dremel with a router is better performance under load and larger shank size. Larger bit = faster and deeper cutting. My Dremel has run for probably over 130 hours on my CNC machine and it’s showing the signs. It can still cut accurately but there is now a problem with the power, and it is starting to become a bit unreliable.

The first problem is how to mount the R2400 to my CNC machine. The solution I came up with is to press my Dremel into service one last time to cut some 1/4″ MDF. I will sandwich the parts together to create a holder that is 1″ thick with a back plate of 1/2″

The design was done in Google Sketchup:


I then rendered it in Kerkythea for fun:


Now to start cutting…

Coaster Sets Made Using CNC

For Christmas 2008 I made coaster sets as gifts. I took pictures at the time but only now am I getting around to uploading them. I hope they provide inspiration for someone else. If the subject matter for the coasters seems a bit odd or random, it’s because most of them were designs intended specifically for the people they were given to.

Each set contains four coasters and a holder and involved about seven hours of work. The wood is 1/4″ poplar. The inlay is Premo! polymer clay. The items were finished with Varathane. Cut using 1/8″ spiral upcut endmills and 0.0571″ endmills. Designs were made in Solidedge 2D and the toolpaths were generated in CamBam Plus. On the bottom are thin discs of cork, glued on with Titebond II.
