CMS-OF finger joint jigg

[Bainiet]

Because dado blades won't fit in the TS-75, I looked for an alternative way to make finger joints. The router is the next stop. One problem remains: How to re-locate the workpiece consistently so all the fingers will match the opposing gap. I know myself This IS THE REAL CHALLENGE [crying] Matthias Wandel's box joint jigg looks great but uses a groove in the table saw. This is something I miss on the CMS [mad] Nevertheless I 'stole' the idea and made something of my own. 12 mm router bit make nice fingers but the jigg seems to be not accurate enough (yet). Probably lack of my skill or the fact that the sliding table of the CMS isn't that accurate  [sad] Not to mention that the plywood isn't as flat as I want it to be but that's due to the changing humidity levels in my garage [unsure].

Interesting to see. Thanks for sharing.

Cheers,

To do this sort of thing I would opt for a dedicated jig, not a table ... though Rembo showed something quite cool (and seemingly very accurate) for box jointing via a table.

Any specific reason you're going the table way?

You might like the original Incra jig.  Inexpensive, precise and you can also outfit it with metric sawtoothed racks if you prefer...

I recently bought this jig, haven't had time to use it yet but it comes highly recommended:

I'm looking at the gifkins ... I'm thinking that or the vs600. Please let us know when you've had a chance to use it in anger.

Not cheap!

If you want a very accurate way of setting the router fenece, and doing finger joints plus dovetail, sliding dovetail etc then the Incra fences are great, I attached mine to the CMS as shown in this thread. The problem with lots of the off the shelf finger joint jigs is that they are made to run in a slot close to the router bit, so you either need to make a table to go on the cms with a slot in it an clamp it on the CMS, or use something like the Incra
