Finger joint bits are used extensively commercially in CNC machines and commercial shapers, but very seldom in smaller woodworking shops so setting these up is not well documented. This video shows one easy method of setting up and using the router table with the Freud 99-037 Finger Joint Bit in a router table.

My way of dealing with it on my commercial FJ plants is to set the cutter height so that flipping a piece after profiling results in a perfect match. Also, not discussed here is that in order to get a strong joint, the length of the fingers needs to be very carefully set so that you can take full advantage of the wedging effect of the two profiles when they are pressed together... The fingers should not "bottom out". They should not be too short that they leave voids on the end of the fingers though. You need to experiment to get it right though it differs with different densities of wood.

When using finger joint bits, raise the cutting bit so the highest tooth's center is flush with the top of your 1st board. For flush joining 2nd boards, lower the bit to the center of the valley between the 1st and second tooth. you should now be cutting flush nicely jointed boards without the need for the plastic.

@guyh.4553 6 жыл бұрын

This is a useful bit for joining long lengths of wood to make planks or especially wide continuous wood with woods that are generally not available. This goes for wood that is especially varying in widths. The biggest problem with the shim is that, in the way you used it, long cuts won't work. You have to reset the bit height.

Ha! Exact issue I had! I ended up making a couple keys after I nailed it down so I can quickly adjust the bit and match it up. But I think you’ve got a better idea here if I can find the correct thickness material.

I used to work with my old man at a timber laminating plant, we used a finger jointer to create the required lengths for the beam work. The joint router was a big old machine with 3 cutting heads on it, 2 of them faced the end of the boards to square it up, then the finger cutter would pass over one board end, scooch over to the other board (there was a board end in either side of the machine) and cut that, the clamps would open, you'd fire the board through and repeat the process. It'd then be passed over to the rammer machine, where the ends are filled with melamine based glue, pressed together (with pneumatic rams, not hydraulic) to the required lengths, cut, then left to cure until the following day, when they get their first dressing through the 4 sider.

We use these finger joints where I work. We do long structural beams 60 feet and more depending on the job, and the joints are very strong. Obviously we don't use a router bit like this as our machinery is rather large. The entire finger joint line is about 400 feet long from start to finish.

These are great for gluing up boards from planks. And with a bit of math they are amazing for reinforcing a mitre joint. And it makes them look really neat. Though given what bits like this cost, I'd say that for the hobbyist it's a better idea to spend the little bit extra and buy a spindle with a set of cutters and bearings. The extra flexibility is so worth it.

hello from France, Switzerland border. In French this is what we call " fer à entures". Check those words on KZfaq and you will find some videos, in French for sure but you will understand drawings. That is what we use for example to link several boards to get long boards, before to glue laminate them. We build glue laminated structure up to 25 meters long in my workshop.we won the universal building exhibition in Milano in italy last year, for the French building. This kind of joint add a huge resistance at the end of each boards increasing the surface for glue.

I actually just repaired a futon that that had the long members spliced with this joint. Except it was about 1 in wide interlocked. I'd say its reasonably strong but the wood did separate on the joint exactly. So my initial impression is that it is not as strong as an actual unified piece of wood. As I think about it, it does seem like its essentially endgrain to endgrain since you cut both sides at an angle. Whereas a straight finger joint has smooth sides for a solid gluing surface.

Hey colin, nice video. Really helps out to understand the orientation! I was wondering though would it be possible to set the router bit in such a way that you have the cutting teeth hitting the board on the first pass with the upper bit or lower bit halfway on the board and halfway off the board and then when you flip and run the second board in reverse positioning those two staggered patterns will then be aligned without having to move the height of anything? Just wondering... Thank!!

I bought one if these to turn two 8' boards into one 16' board to repair a garage door. Close examination of the original door showed they used finger joints. The bit car said 'just flip it over', but as you discovered that doesn't work. Thanks for providing a solution. Follow-up. After viewing your article, I found I could set my router 5\64th of an inch up to cut the second piece. I also tested moving it 5\32 of an inch down to cut thicker boards, and that worked also. I have to use a router with an edge guide because I can't really run an 8' board with the cut edge against the table fence without making a pretty substantial jig. Since I only have to make two finger joints, the edge guide should work fine.

Lowes sells boards that are made from scraps put together with that cut. They are glued together to form longer, wider boards. My thought is that this can be used in a similar way to build "bricks." If all the pieces are the same length, you can alternate contrasting wood and glue different board you make side-by-side until you have a 'brick wall' look.

@gavconway8737 6 жыл бұрын

You will find this joint on a lot of hardwood furniture that's bought from furniture stores. Usually its covered over with dark stains and high polish finishes to hid the fact that the wood is hundreds of off cuts. The furniture looks and works fine but i took the finish off an oak table recently and found that the table designed to sit 10 was made from sections of oak no bigger than your test pieces and they were all jointed together with finger joints. Totally agree that there are lots of cool ways you could use those bits though.

in a visitors centre in kent uk there some large structural beams made from short boards Ieach I think of 300 mm in length and 100 mm width and 20/25 mm thick in horse chestnut with fine finger joints end on end these were then lined up vertically side by side with about 10 rows of similar sized boards all with finger joints so beam was about 200/250 mm in width each joint was staggered much like brickwork . then at at least 3 identical sized rows of finger jointed boards of 100 mm width were laid on top in the vertical effectively providing incredibly strong structural beams of 400mm high by 200/250 mm wide and of lengths up to 10 metres bolted or glued to together ??. These beams are curved for architectural purposes. from a distance they look like a single beam cut from a huge tree but really close up you can see the fine finger joints . Absolutely amazing .obviously engineered on an large scale but had me thinking of what one could do with scrap wood and finger joints ...

@gregpatey6355 2 жыл бұрын

the undesirable offset that you experienced on the first couple of tries can be remedied without a piece of plastic to gauge the cut, just by raising or lowering the bit on the end of the wood (adjusting the bit or router motor up or down)... raising the bit slightly will bring the fingers HIGHER on the end grain, and as you are running the second piece of wood thru it UPSIDE DOWN, the fingers on this piece will be LOWER on the end grain, which can easily be seen when its rotated back to the mating position... the trick is to get the bit in the correct spot so that you can mill the ends of BOTH at at the same time, and then when you flip one of them over, it will make a perfect fit..... if you are doing a one off joint, the way you have shown is acceptable, but if you are doing many pieces to make longer material, getting the bit in the right spot so that you can run several ends thru the cutter all at once will make short work of it....

Yeah, he's messing up the cut every time once the end of the board gets past his fence. He should be using a miter fence and insuring the entire end gets cut, including the "valleys" of the bit.

This particular finger joint bit (Freud 99-037) was annoying to work with at the outset because the packaging does not include instructions that define the distance by which you must offset the bit to make the mating cut on the second piece of wood, and also because the tooth-to-tooth dimension in the diagram in the packaging (21/64"), which you would need to calculate the offset, isn't even CLOSE to matching the actual tooth-to-tooth dimension on the bit. After carefully measuring the bit itself, I determined that the bit must be offset by .080" to make the mating cut. Because the bit is made in Italy, it's possible the offset Freud had in mind was a nice, even 2 mm (.0787", or .0013" less than I measured).

@LimogesDiver 5 жыл бұрын

Ummm: am I missing the obvious here? You set up the cutter to make your initial the initial cut. Make the cut. The adjust the height of the bit so the tips of the blades meet the tips of the "points" (what do you call the peaks of the cut?). Then you run your next piece through it. If you lined up the peaks of the cutter with the peaks of the first piece, the second piece should fit like a glove. Now, I've never used this bit nor a router table, but I think this would be easier than trying to find the right thickness of material for the offset. Also, one less piece of material on your table (the shim) is one less thing to worry about (the shim hitting the blades). Also: what if you don't have the correct thickness shim? Are you out of luck? Router tables are adjustable, as mentioned in this video, and the adjustment is very precise, as mentioned in this video: why wasn't that even attempted?

"Also: what if you don't have the correct thickness shim? Are you out of luck?" I feel like I'm the one missing the obvious, now. If you've a woodworking workshop, you make things. Why wouldn't you simply make the shim?

@FoxCurtailed 5 жыл бұрын

Given that "makers" have an expanding number of tools these days, 3D modeling and 3D printing make it trivial to create a plastic shim like this. Some calipers to measure the bit's offset between valley and peak down to tenths of a millimeter, some quick modeling, tell the printer to start and now you'd rarely need to fiddle with adjusting the router table. Sure, you've a 2mm bit of plastic or two in the shop, now, but it cost pennies to make and doesn't take up much space. I like the idea of testing the elevation of the bit by inserting it into the piece you just cut to ensure it's the proper height now, but why go through that effort for every single cut you make with this bit, when a one-time creation of a shim makes it unnecessary? Different strokes for different folks, I suppose. Woodworking just already involves so many jigs and whatnot already, the idea of 2mm of material being a burden in the shop seems funny given that it'd save you countless table adjustments.

I think the main intention for this router bit is for joining boards in the other direction than what you're doing here. (So it's sort of a replacement for using something like a biscuit joiner for making wider boards.) I think. I could be completely wrong.

@utilityplayer203 5 жыл бұрын

There's a practical limit to the length of joints that can be made with this bit, whether parallel to the grain or perpendicular to it, because the vagaries of the wood (stresses relieved by the cutting process, defects, grain, etc.) will come into play in long joints, and it can be difficult to squeeze and clamp long joints together. The application demonstrated in this video--to join the narrow ends of boards to make longer boards--is the best use of the bit. For edge-gluing long boards to make wider boards (without using splines or a lot of biscuits), there are specific bits available, which create simpler "glue joint" profiles (having fewer and coarser "fingers").

@keepingdistance4404 3 жыл бұрын

Late comment but I have to. The top of the bit should be level with the stock and then you alternate flipping the faces as you run them through. This flips the gap from top to bottom with no other adjustments.

1. Center the bit on the thickness of the first board. 2. Make the cut. 3. Turn the second board over (top surface is down). 4. Make the cut. 5. Brush glue on both surfaces to remove air. 6. Turn top up on both pieces. 7. Push the pieces together. 8. Clamp until glue dries.

Surely it needs to be off=centre by half a tooth width? Otherwise you will get the same cut either way.

@@janhatton4405 turn the board upside down before cutting the second piece. The mirror image will fit together.

Nope. Jan Hatton is correct; the bit needs to be offset by half the tooth pitch. Simply turning the second board upside-down before cutting will work ONLY if the exact thickness of both boards meets the requirement of this half-pitch offset.
