Drilling Infinity Tools Fluting Jig to fit My Router

[George Bokros]

How would you approach drilling the fluting jig to fit the router? I tried to drill to fit it to my DeWalt 1 1/4 hp and it did not come out to well. One hole was off a little and when I attempted to do the counter drill so the screws were below the surface of the jig the drill caught and lifted the jig and I drilled the counter bore all the way through. I learned I needed to clamp the jig to the drill press table to avoid the grabbing but am still wondering how to ensure the holes are properly aligned.

I know I need to center the jig and have the Infinity Tool alignment pin now to do so. I am thinking about using double stick carpet tape to stick the router base the the jig and drill using the correct size drill using the router base as a guide.

I would use my drill press clamping to hold the jig to the table when drilling both the through holes and the counter bores.

Your thoughts??

Thanks

I think you're on the right track, George. Whenever I make another router sub-base, I use the OEM sub-base as a template. Center it, double-stick tape it, use a bit to match existing holes.

Keep track of the orientation of the router so the switch and other controls end up in a convenient place.

If I read this right, you are also using a drill bit to countersink. They have the wrong angle for most countersinks. You can pick up a cheap set at HF. They come in handy. Get the ones with one flute.

Not counter sink counter bored. The screws are not flat head but round head and a counter bore is needed not a tapered seat for a flat head screw.

Got her done this morning and all is well.

Thanks for the response Rick.

I can't count all the special sub-bases I've made over the years, but I can count all the ones where all three holes lined up the first time- 0.
