Thank you all for the welcome greetings and for taking the time to help a rookie. I expect I'll be checking back here often once my "new" PC 690 router arrives in the mail. It's not fancy, but the price was good and for a used router it appears to be in excellent condition, plus it seems to be a classic from my research, and I think it's simplicity will be a plus for a beginner like myself. Maybe later I can graduate to something fancier, but I'm hoping this one will serve me well to start with.
Now, a couple of questions:
James and Chuck - I like the variable spacing dado jig that James built, as it looks pretty simple and foolproof to build and use, and does not require template bushings. But a couple of questions:
1) Regarding Chuck's comments: "The only drawback is that you must use the same size bit as you used to cut the groove between the two guide strips. The best way to use it to take a piece of your shelving material and scribe a line down either side where you want it and then line the edge of the jig groove with each side."
So you can never use a different size bit without making a whole new template, right? That does seem a little limiting. Also, that implies that if you have a bit sharpened, which I assume would make the diameter slightly smaller, then that bit could no longer be used with the jig, correct?
2) James - is there a reason you used plywood and not hardboard for the base and guide strips as was recommended in the Woodsmith Plans article you referenced in the other thread? I would think tempered hardboard's slick surface would allow the router to slide more easily along the jig.
3) James - Is that hardboard that you used for the square auxiliary router plate you attached to the router base? And why did you make this auxiliary plate when you could have just used the router base itself? Is it because the router bit might not be exactly centered in the original router base?
