Mystery tool (to me) and missing parts maybe

[fiatben]

An acquaintance of mine came across this and has given it to me. I can figure out that it is a shaper head. I just think something is missing because I can't see how to mount the blades. There is no name nor any marks for identification. I thought maybe one of you might have one or have had in the past, or just know more than me about what I see.

It looks to me as if the blades are supposed to be held in by clamping pressure. Drop the clamp wedge in against the tapered shoulder, and back the jack screws out until the blade will drop into the slot at the center. Then screw the jack screws in, raising the wedge and clamping the blade against the body of the head.

I'm not clear on what keeps the blades from shifting when you tighten the clamp wedge, though. Are they tapered at all?

I'm thinking rosette shaper. WAG!!!;)

Agree on the rosette cutter. Am guessing the chosen cutter mounts against the middle on the base and is clamped there by sliding the wedge into the slot and tightening all three screws. Looks like this will cause the wedge to push against the cutter to hold it in place.

What's in the closed package on the tight side of the picture?

Don't see how to use the round shaft. It should mount to the base and extend into a drill press.

I think the 'round' shaft large end is tapered. I think the small end has a flat or a 'non round shape. The 'disc' center hole also looks 'not round'. Is there a set screw in the 'disc'?

That looks a lot like this one sold by MLCS

'Missing' part = dowel for driving the tapered arbor out of the cutter head.

I assume the unrevealed side has a tapered hole for the arbor.

Thar's gold in them there parts!!!

I think you guys nailed it as a Rosette Cutter. I have a couple of more pics, comments and questions....

The blades are not tapered. Flat steel with matching profiles at reverse angles. The wedge does indeed raise up on 3 setscrews to secure the blade. The mounting arbor is tapered to fit into the back of the body and the other end has 3 flats for securing it in a Jacob's chuck.

Here are better pics of the parts:

Here it is with a blade inserted and the arbor in it:

Questions I have are;
1. There is no provision for securing the arbor into the body. There are small holes in each end of the arbor, but neither is threaded. Neither is there any setscrew in the body itself.

2. If the arbor is friction fit (and it does fit pretty tight just by hand), then I'm missing the pin to drive it back out. There is a pin shown in the Bit Horn cutter in the link above.

3. It looks like the blades have to be centered by eyeball or feel. There is no apparent mechanism for insuring the blades are perfectly centered in the body.

Oh, and the red thing in the first pics is the lid for the red round case it came in.

The tapered arbor is typical for drill presses. Most machine tool drill chucks and quills are connected by tapered shafts. Yes friction fit. The 'holes' in the ends of the 'arbor' are center holes for when it was machined. As for cutter centering, I guess equal spacing at the ends gets that done. Any rod will do to separate the arbor and head.
