Awhile ago, I blogged some preview information about the forthcoming Domino Self-Centering Guide SCG-10. The product has come out and looks very useful.
If you've followed my podcast at all, you've seen me use some third-party narrow-stock spacers that are fitted to the front of the pin-style Domino. The pin model is harder to find these days so the fast pencil-free registration offered by the spacers hasn't been available for everybody. The SCG-10 solves that problem.
In this video, I'll show you the product, how it fits to the Festool Domino body, and how to calibrate it easily. I then do a series of demonstrations to show forming a 90ยบ joint (like a rail/stile joint) using the SCG. One demonstration shows using the SCG for its centering function and the other emphasizes the equidistant offset provided by the SCG and how you can use that to offset mortises.
The key to a Domino is getting your reference surfaces correct and these demos try to show that briefly. If you want more detail on reference surfaces, you can catch the fourth episode of my sculpted Mahogany vanity series or you can look at the third video of my four-part Domino review.
The calibration procedure shown in this video isn't the same as the one outlined in the manual. The manual's procedure assumes the center line on the bottom of the Domino base is reasonably accurate. For my Domino, it is considerably off, but I calibrated my cursor hairs exceptionally well. The basis of my calibration is to use the cursor hairs to get it done in one try.
I think you'll like this product. For a pin-based Domino user, it provides more flexibility than the narrow-stock spacers (of which I'm a huge fan), and for the paddle-based Domino user, well, now you can put your pencils down :)
Addendum:
In the comments, someone said that while viewing the last demo, the joint didn't look flush. Admittedly while editing the video (way late at night), I thought, "that looks bad", but I knew I had felt it and it was flush. Well, that someone else noticed and asked, I went to verify. Yes, it is flush on the top edge where I glided my finger, but the back had a gap...
I cut that board in half, put the SCG-10 back on the Domino, set it to the width of the stock "plus a little" to offset the Domino and replunged. This is the result.
The outside edge of the frame is very flush.
Here you can better see how flush the side is. The surface has a small step mostly because the cross piece (one with the Domino 2 pictures ago) is at the limit of what I'll hold to plunge so I don't think I pressed as hard on the top fence as I should; it's minor, but usually I get the surfaces more flush. Really, don't do pieces this small without using a holder. :)
