SWMBO say's if he's not obviously pissed/scowling, it's a smile. I saved the big smile for right after cutting the first mortise, considering that I futzed with the necessity of damn near a separate, shop made, mortising jig for every single mortise on my current project.
Actually, the second hardest part in gearing up for the first cut was making the mobile base; the first, finding a place to put it.
The machine is intuitive in its methodology and the learning curve basically non-existent for cutting mortises, which is what is needed for the current project, and most of my future projects using mortises and loose/floating tenon joinery. Judging from what I've seen with DJM, and from talking with other owners/DAGSing, this is the number one use for the machine.
Tenons are a bit more complicated, but not much, and only because they require the use of templates, which the three tables follow using a stylus.
Mortises don't need templates, and at this stage, neither do I. Template$ are expen$ive.
Basically the multi-router is three tables; the router is attached to a vertical table, which moves in the z axis, with sliding stops which can be set to define the up and down limits of a cut; and two horizontal tables, which move in the x and y axis, both having stops which can be set to limit length and depth of cut.
It's that simple, and if you've ever used a stop block for a cut, you're off to the races immediately.
FWIW, the engineering is absolute awesome. I don't think I've ever seen another piece of woodworking equipment with this level of precision.
Every wooddorker needs to put his hands on one just for the fun of it ... but, what really makes the multi-router experience astounding is all that previous screwing around with the time consuming, imprecision of homemade mortising jigs for compound angled joinery.
