After reading several glowing reviews here and watching Charles Neil’s video I decided to purchase a kit from Kehoe. I ordered the K-12 Master Kit online and it arrived a few weeks later.
As suggested in the enclosed directions I’m practicing on scrap wood before using it on my project. So far I’ve tried it on pine and cedar, both softwoods. My problem is that the dovetail doesn’t seem to have the same angle as the included splines. The dovetail I cut seems to be too wide in the front and too narrow in the back. Therefore the spline goes in about half way and won’t go any further. Since these are very softwoods I can hammer the splines in but then there’s about 1/32” space around the dovetail at the front.
One thing I’ve noticed, and I don’t know if it matters but, there were two dovetail bits included with the kit. They have different diameter bearings. The 5/8” bearing is about 1/16” further away from the tip of the dovetail than the other bit. The bearing is pressed and won’t move. It looks like I’m cutting too deep but there’s no way to adjust this significantly and keep the bearing in contact with the jig.
Also the clamps included in the kit are insufficient to hold the jig. The vibration of the router moves the jig. I used other clamps to hold the jig in place.
Other things I’ve had to work through: no where does it say how thick the wood has to be to cut the spline. The included splines are 7/8” but it would depend on how deep the dovetail is. And the jig obviously must be clamped in place. It’s easy with an open box like in the video but anything else is a challenge. Lastly, your workpiece must be clamped at 45°. Again not a problem with a small box like in the video but with other projects it can be a challenge.
I’d hoped to enhance the look of my project with this kit. But if I can’t get it to work in practice it isn’t going to touch my project. Any help or suggestions are appreciated.
