Topic tags/keywords: question router joining

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.

I have the jig….still in the box. Haven’t had time to use it yet. However, I correspond regularly with the manufacturer in Ivanhoe TX. I guarantee you that, if you go to his web slite Kehoe, he’ll be very happy to help.
He’s also a moderator on woodworking talk. He is “Texas Timbers” and his name is Kevin. You can go there and get his personal email, too.
Tell him I sent you and he’s likely to not talk to you… hehehe.

jeff , lets see if we can get you squared away, first of all the dovetails are designed to be on a 1 degree taper, turn the spline around, its made to go only one way, the provided sled is made to cut the spline on the same taper as well, this adds to the locking capabilities of the joint, as to thickness, I use 3/4 to 7/8 , its a simple case of measure the depth of the dovetail, and use material slightly thicker ,so you have sanding room, to clean up the dovetail nicely, the clamps, I cant speak to, mine did fine, as to the different bearings thats so yo can cut various widths of dovetails, you want to come in on the left of the jig slot and leave on the right, this cuts the angled slot, the different widths depend on the bit and the bearing you choose, there is not alot of height adjustment, its very difficult to make an adjustable bearing on a router bit, and simply put making the jig thicker cost a ton more , as to the angle on the spline, sample it could be slightly different, its a basic guide, what you want to do is to angle the blade on your saw until the angle matches the bit you are using, another thing that happens is some times the bit angle can be slightly off, not what we want, but when they are making these things, sometimes a slight varience can occur, again, just adjust the blade ange to compensate …hope this answers your questions, but I will forward Kevin this thread so he can respond as well

Thanks guys. I saw this last night and we have a phone appointment later today. I should have posted something here. But if he sees your explanation first Neil he might not need my help. Add it to my tab if there’s any room left on it heh heh.

Gene get that box opened and get busy!

Thanks to Gene and TexasTimbers who contacted me right away about the issue. Just takes some practice. I wish all suppliers stood behind their product like Kehoe does.
