I just recieved this mystery head and would appreciate any opinions, comments or explanations on how it works. I can,t post a picture but the e-bay item # 3404991869 should still be viewable. It appears to be a universal/compound vertical mill head for a horizontal mill. on one side is a rotary t-slot mount, marked in degrees of offset, 40+- the opposite side has a small gear output, driven from the spindle at a1/2 ratio.the drive for this right angle power take off is controlled by a coller around the spindle input.The spindle is of very high quality, with spring loaded tapered roller bearings. The chuck uses a collet system iv,e never heard of, Chi.Co grip #242. it looks ery close to an er-40 and came with a reducer down to about an er-20. the spindle has a very good locking system and has three rings milled on the head, like ratchet ramps, stops. The arbor is also marked with division marks- plus or minus 15 degrees on opposite sides of the spindle. two questions: what is the side drive used for, and why does the spindle have all these indexing stops, division marks on it? I only paid 26.00 US for it, I was told it might be a shaper attatchment but nothing goes in and out. This would be a good start for someone wanting to build a small mill. thank for listening, Doug

I couldn't get your item number to work. Sure it's the right one? Is it from an auction long expired?

The correct number is 3804991869. Looks like nothing I have ever seen, but is a helluva deal for $26.00.

It looks like you are missing half of it. The part that is missing is the bracket that attaches to the column of a horizontal mill to drive off the spindle. It should also have the other half of the swivel for compound adjustment. Can't help with the brand.

thanks JC, I looked up the proper # in my E-mail storage. How did you find that item number? I think this head must have had the motor mounted above it, so everything tilts and swivels as one unit. like a BP? this would work if the missing swivel adaptor was an angle plate. Doug

No, its a steering gear from a 1967 Volvo. But I'd still have bought it at that price because it looks cool.
