I bought the Woodriver guide system for cutting down large panels. It is no track saw, however for the 8-10 panels I do a year it is fine for me. The system has a saw/router base where you need to mount the tool to that base and it has channel that rides along the aluminum rail. I decided to dedicate my 6 1/2 Ridgid saw to this system. I put on a new Diablo 40 tooth blade on the saw (same as blade I took off). Tried this out on a 1/4 inch panel and started seeing smoke. First thought was this system doesn't work well and just wasted my money. Then I remembered this was the same as the previous blade. I put the blade on with the imprint facing out as I do all of the blades I own. Well for this blade it rotates in the wrong direction with the imprint facing out. I dismounted the saw and reversed the blade so the rotation is correct and what a nice smooth difference. I hate it when the mfg does things like this, but I also should have looked closer when installing it the first time. The 7 1/4 blade installs with the imprint out.
