Good day

So, I made the “Rolling mortise jig” and the “Router lift”
And yesterday I tested it for the first time.

I started the first mortise by cranking the “Lift” up 3~4 turns and push-pull the sled and another 3~4 turns and another push-pull.

But then, I realized that actually there is no “Fence side” or “climb routing” and I can push or pull the sled.

I ended up working simultaneously with both hands…the left hand pushing and pulling the sled and the right hand, rotating the Lift continuously…every mortise took me some 15~20 seconds (1-7/8” long and 25/32” deep).

I cannot tell how long took me to make all the 8 mortises because taking the pics (136) in-between took me much more time than all the mortising.

The jig is not limited only to “edge mortising”, if you mark the mortise location, remove the “sled stops”, and align the marking with the “locator”, you can make it anywhere along the board.

Nice job Niki. It looks like Festool better watch out. You might be stealing some of their Domino market share!

Festool? Domino? Did somebody say something? Oh, Niki! Another great jig and demonstration! Thanks!

Niki,
You are the master of improvisation! That is a very ingenious invention. And, the result was a good, tight, well fitted joint!

I love the idea of these “floating tenons.” I guess I’m just lazy, but I keep thinking there has to be a better way of joining wood, that is not so labor-intensive as mortise and tenon. Maybe if I had the benefit of having a master woodworker teach me how to do it, it wouldn’t be so intimidating to me.

Thank you so much for your so kind words

As I know, Domino could not supply the demand in Europe and that’s the reason that it came to USA a little bit late so, they have their market…it’s just so expensive, well, for the Americans…here in Europe we are used to such a high prices (at list double than USA).

Why do you think that I made this jig?..
First, my hand tools skill is near zero (or below)...
And second; I can cut the tenon on the table saw and the mortise on the router but in this case, there is a place for two mistakes; or the tenon will be too narrow or the mortise can be too wide..

With this jig and method (floating tenon) I can have a mistake only in the dimensions of the floating tenon that is much easy and cheaper to make a new one than, for example, new legs or aprons…
