Another whatz this

[Plum Creek]

I am new to Machine work, and trying to absorb as much as I can. I ended up with several of these items from a sale, and was wondering if anyone had any information they could share about them.
The L shaped item looks similar to a chuck jaw, welded to a axle stub and turned down to a somewhat eliptical shape.
The other I assume is a facemill, but cannot find any info on it. The mfg is "Milling Specialties" and is stamped 15 HD 400. The base is 4.72" with a .63" drive slot. Cutter dia is 4.0"
Assuming I keep one of them is there an R8 collett that will drive this cutter?
Thanks

The big round one is a facing mill, you need an arbor to drive it. They should ave an R8 arbor for that. Thats a nice piece! The other thing looks like somebody welded a a shaft to a chuck jaw, who knows for what purpose. Do you have the other jaws like it?

While you do need an arbor to drive the face mill, I wouldn't try to drive it with an R8 arbor. A 4 inch face mill is far beyond the horsepower capacity of an R8 equipped milling machine. A 50 taper arbor would be more in tune with that cutter.

I suspected that might be the case. I asume from what I have read, that chip load vs hp would be the issue here? Well hopefully I can trade someone for R8 tooling.

That's a shop built soft jaw. There should be 2 more to match it if it was for a 3 jaw chuck.

The other is, as you guessed , a face mill. I too wouldn't run that on a 2 hp machine. What are you looking for to trade? Or sell?

I don't see what the big deal is about running that on a R8 shank. Light cuts on steel and you can hog on aluminum with that. I have a 3" that I use all the time on my Bridgeport, Great for cleaning up faces.

The difference in weight of a 3 and 4 inch face mill is not to be taken lightly. (no pun intended) The 3 inch maybe, the 4 inch definitely not IMHO. The R8 won't hold up.

Actually my mill is a 3hp, but probably still a few hp short.
There are 3 more of the chuck jaws. stamped CL 715 CJ, CS 65
I would prefer to trade, but I would be open to a sale although I havent established a price yet.
I'm looking for Quality R8:
end mill and shell mill colletts larger than 3/4".
Morris taper collett
flycutter
Kurt tilt vise (doesnt have to look perfect)
a variety of things iI cant think of right now. I will make a full list before list it in trades.
Feel free to pm me
