This just arrived today from MA, via two friends. One picked it up form an auction for me, the other picked it up in his box truck and dropped it off on his way to White Lake, MI.

It is a manual louver groover, model JFA I believe. Motor data plate is missing, common.

Cutter is nothing more then a 2 flute router bit.

The material clamp and grooving function is done one lever on the right of the motor.

I can tilt the head (not sure what I can accomplish with that yet) and the table has a wedge that can be moved around for different height stock.

Hopefully I can make a few grooves tonight and figure out how this thing works.

I also lucked out and found another machine with a bad motor (supposedly) that I am having shipped to my shop.

Curious how that thing works out. Looks like you could achieve the same thing with a horizontal bore and a jig. I know the horizontal bore would spin a little slow but you know... I have to try to find a "different" way.

Overhead shaper would work but is probably quite a bit more expensive and doesnt have near the name. One of the shutter guys around here just cheats and uses a 3 axis cnc.

Well, I was doing some cleaning and looking this thing over (found a few repairs) and curiosity got the best of me.

I wanted to see how the innards worked.

Pretty interesting drive set up, the black part is some sort of hard rubber, the center bore looks to be worn.

Essentially, one could clock that end with the bit in 4 different positions around that end.

There are lots of adjustments and lots of flexibility with this thing.

I ended up getting a second machine that supposedly has a bad motor (it just buzzes) because this one has had a couple face plants in it's day and had numerous repairs.

I swapped the motors and then set about trying to figure this thing out.

I have no clue if I am using this thing the German way, but I made some louver grooves.

There's an aluminum router template I checked out recently for a shutter job. Looked pretty simple. Just clamp it down and use plunge router with straight bit and top bearing. This looks cool though

That's cool. Wondered how they make them things.

Is there anyway to set the domino up to make the same cuts?
They were using the pin fence domino and just cocking it across the board.

I can set this to any angle and all I have to do is keep advancing the stop.

I would consider a domino for one or two shutters, but for a whole house this is fairly quick. If I start to corner the market on shutters I will try to find the automatic version of this machine.
