Default How to setup a Finger Joint Assembly Router Bit

Hi all experts.

I'm struggling with a simple setup routine for my Finger Joint Assembly Router Bit (copied this from the web, don't know the correct name in English).

I've made a list with setup values(router bit height from table) depending on the thickness of my boards. But it seems like I'm doing it wrong. Despite my (in my opinion) good calculations I'm getting some difference between the two boards when mounting. I've read that setup should be at centerline on both bit and workpiece, but that's VERY difficult to measure.

I'm using it for both end to end and edge to edge. It's very tedious to setup with the trial & error method.

Hi Anders;
What are you building? Are you trying to put end to end & edge to edge together at same time? Try using a glue joint bit for edge to edge or even biscuts.

Here's another set of instructions for the finger joint.

Hi Anders

Sounds like you are takling about a box joint, some times called a Finger Joint, a jig is needed to get them right every time...
Many sale the jigs but the best one I have found is the OakPark one...it can be used in many ways not only for the box joint.

see below

You don't need all of them but you will glad you have all 3 of them.

Thank you for your quick response.

My question was more of a general kind, I sometimes use finger joint bit instead of biscuit's when I glue edge to edge (like doors or sides). I think it looks nice. I'm also using finger joint bit end to end (strength).

My real question is..
I wonder if anyone have found out a simple method for set up.
The "shoulders" must be equal height and this means that the bits centerline and workpiece centerline must match, this is difficult to set up. I would rather have a height measure from router table to one of the teethes on the bit depending on workpiece thickness.
The attatched PDF describes the set up, but it doesn't contain any tips for doing it the easy way.
Maybe there is no easy way.

I don't think he is talking about box joints.
I think he is actually talking about finger joints as per this link....
Finger Joint Assembly Router Bit - Toolstoday.com - Industrial Quality Carbide Tipped Router Bits
I can't help with the set up though, except that it seems you should only be using the router table and not a hand held router.
Looking at the picture I can only assume that you should align the top of the cutter with the top of the wood. Looks like you would also have to ensure that the wood is the same thickness as the cutter.
Not sure as I've never done it.

I guess i was too slow typing.
So it is in fact a finger joint cutter.
Looking at the pdf you posted, it doesn't seem like there is an easy way.
Do you have 'micro adjust' on your router ? That would make it easier.

Hi,

Box joint wasn't what I meant, but this jig looks really nice, I have to check availability in Sweden. I have seen some videos showing some real nice pieces made with these jigs and easy methods, requiring very little set up.

Their router tables looks wonderful, I haven't found any reseller in Sweden.

HI, Maybe I was to slow reading

Yes, I have the possibility to adjust my router. The easy way may be 6 fixed workpiece dimensions (13, 19, 22, 25, 32 and 45 mm) and make set up templates for each thickness.
