I recently acquired a Palmgren 800 rotary table for a faction of this cost.
I would like to modify it to mount horizontally or vertically on a small mill.
I'm open to suggestion before I start hacking.
Thanks

I assume it mounts horizontally now, right? If so, no need to hack it. Just put it on an angle plate.

Strange that you asked this on a Mini Lathe group. I had a discussion last year about doing exactly this turn out getting a large 90¡ã angle piece to mount the rotary table to? was the best solution. Of course this is a pain if you want to use the table horizontally as it has to be unbolted from the angle piece.? Ralph

Thanks As the flier in the add shows it was made to mount on the toolpost of a lathe. I could mount it vertically with a couple of 123 blocks but not very steady. If I put it on a large angle plate I would not have enough room between it and the mill spindle.

I barely can?see it mounted on the lathe on your link page. Do you have the flier you could post or send to me?
You would have to deal with the height on your mill no matter the mounting method. The rotary would not be mounted directly under your mill spindle so I do not see a problem there.

I didn't look at the flyer before. I have a Palmgren milling attachment, and your easiest option for vertical mounting would be to clamp the rotary table onto the table of your mill the same way it attaches to a toolpost, using a? T-nut, 3/8" bolt and a bar from the usual clamping kit.? This would hold it as sturdily as it was intended to be on a lathe. (Which is not very).
But I suspect you'll mostly use it horizontally. For that I would remove the Palmgren mount and its lead screw and fasten the rotary table to a plate large enough to clamp onto the milling machine table with the standard clamping kit.?
For this you'll have to make four threaded holes in the back of the rotary table for screws. I'd probably use socket head cap screws and either recess them or arrange for them to fall where they? don't hit the rails of the milling machine table. You should make these easily removable because you'll have to put the Palmgren attachment back on to use it vertically again.
But if I were doing this, I would still mount it vertically on an angle plate, using the same four screws. I disagree that angle plates are too big. Cheap Chinese ones are made of cast iron and come in different sizes, and if necessary you can saw one down so it isn't any bigger than the? rotary table.? This would be massively more rigid than that Palmgren attachment.?

The mini-mill group is pretty much dead, so it's fine with me to ask milling questions here.? Most of us do milling here anyway, on our lathes if we don't have mills.

I agree that this is not going to be a super rigid mount. The only "true" surface on the back is the dovetail. I'll have to take it apart to see how thick the unmachined part of the back is. If I had not gotten it so cheap it would not worth all this fiddle'n.

Thanks Thanks. This is a very active group with a lot of diverse users. I try not stray too far from the intent of the group.

An 8" rotary table seems awfully large for a mini-mill, even in the horizontal position.? The x-y table? is only about 4" wide, so an 8" rotary would limit the y-axis motion of the mill severely, and the height (& weight) would be quite cumbersome.? I would go no larger than a?5" rotary table, and a 4" is probably the most useful on a mini-mill.
That said, if you have or are panning on obtaining a larger mill, then the 8" would be an excellent addition, especially with a dividing plate.

I have to admit I didn't even notice this in the original?email.? Yes, probably too big for a mini-mill.

I think I would get a chunk of my favorite alloy and mill a dovetail slot, then make whatever base was appropriate. The base could be locked to the rotary table with the gib screws.

??? ??? you can get a 3" tilting rotary table on Amazon for @ $
70.00 & a 4" starting @ $150.00 . Either of those would give
you a nice working area on a mini mill .

OK let's see a show of hands. You already own this piece of hardware. You would leave it sit'n on a shelf and buy new. That goes against my grain. :)

Another option is to mount it on a drill press table. That lets you do light milling with the drill press & makes it easy to drill a pattern of holes for things like mounting flanges.
