$1800 and the rotary table and vise is not included. Seems pricey.

Nice idea.

This is exactly how I feel about it, great idea, steep price.

NO kidding. I'll bet Ig makes an equivalent for under $300.

Besides being heavy, these are also complicated to use.

Yes, it does not seem to be very complicated. Some welding, some CNC
machining, not really that much seems to be involved. Just three large
pieces of iron is what is needed.

Do you have a CNC rotary table, Ig? They're far more useful than a trunnion
for accurate work. Trunnions are basically production tools with multiple
sets of fixtures; unless you get into the really expensive ones, they aren't
generally high-accuracy devices.

The Haas trunnion with a vise never looked like it made a lot of sense to
me. It isn't good for fixturing multiple parts and it doesn't seem to offer
a lot over a vertical rotary table, unless your particular part
configuration just can't be set up on the table itself.

On the other hand, a rotary table that can be set up vertically can be very
useful in a small shop.

Yea, I'm not a hobbyist, We have plenty of machines here that could
handle that.

Yes, I do, I think that I showed it and how it turnsto you, but
perhaps the beer interfered.

Yeah, I thought you had one, and it's pretty substantial.

Think about what you can fixture on that, set up vertically, with a
right-angle plate on the table. Compare that to what you can mount in a vise
on a trunnion. I don't think you'll see much difference. If you're thinking
of one-off jobs, getting a part set up accurately in a vise probably takes
as much time as setting up on the angle plate. If you're thinking of batch
work, a little fixturing on the angle plate probably will out-perform the
vise.

I just don't see where the trunnion has much to offer. The trunnions I'm
familiar with typically have four sets of dedicated fixtures, each holding
multiple parts, for higher-volume production work. That makes sense. A
single vise on a trunnion doesn't make much sense to me. It looks like a
gadget in search of a reason to live.

Mounting a workpiece directly to a rigid, T-slotted tilting table would
likely serve the needs of most home shop machinists.
http://www.ebay.com/itm/Milling-Mach...-/180641121361

I bought a nice used USA 8x6" table for about $60 IIRC, several years ago,
and it's suitable for mounting other tooling to if needed.. but a more rigid
mount with the workpiece clamped directly to the table.

For tiny workpieces, I have a pivot-pin type slotted tilt table about 4"
square, or angle vises to use.

The trunnion with integral rotary table looks interesting, but I can't think
of much use for it.

I've seen video, most likely on youtube, of them being used to machine
miniature gas turbine rotors or the wax master for lost wax casting. The
item looked very much like a turbocharger rotor.

Once you have the CNC rotary table, however, you already have the multi-axis
functionality. Then all that particular trunnion seems to give you is a way
to hang a vise out there in space.

My guess is that the current generation of machinists is a lot more
comfortable with vises than with angle plates and clamps. The same is true
with faceplates on a lathe. Some people will jump through hoops to fixture
something on a mill, or in a lathe chuck, that's a piece of cake with a
faceplate.
