Guys I was wondering what your thoughts are on this subject. I would like to get a milling machine, some day, but for now doing some small stuff I thought one for the lathe might fit the bill.

Theres a couple on Epay for my SB9A, but they are high, a few more bucks and I can buy a small bench top milling machine, and I dont have the room or that amount to work with right now.

There is some Palmgren 250 on epay, reasonable. Would the 250 be too big for the 9a?

TIA Vince
 
I made a milling plate for my South Bend 9 inch lathe. It is easy to install and you can bolt a vise to it or clamp the part right on the table. It is super cheap to make too. just a 3/4 inch plate and a short piece of round. I made it on my lathe and drill press. It works well for small jobs. I made mine from a piece of ground plate but it doesn't have to be ground, just flat.

I don't think so. I have an SB 9C that I fitted a Palmgren 400 to. Please see:

Though I do kinda like Mark's idea too.

I've seen some really cool work done with a milling attachment on a lathe, but I have one for mine and other than a few operations that worked better than on my vertical mill, I don't care for it all that much. It depends on what you want to make, but I'd say if you can swing a mill for money and space, you'll like separate machines better. There are lots of examples of shop-made attachments that are very nice tools.

This looks like a cool project in that direction: http://www.statecollegecentral.com/metallathe/MLA-5.html

That looks easy enough, but how dose it work for vert work?

Can you post a pic with the vise on it please.

Also what is the anchor made out of? It looks like alum?
 
I made a spacer that I could mount the 250V on top of the top slide. Only good for small light milling as the stack is a bit flexible. A better solution is to mount onto the longer slide that was a kit for mounting a 4 way tool post and the reverse parting tool post. I had one when I had the Atlas, it worked much better due to the increased surface area that holds onto the carriage. One of the other members just made a new one for his Atlas. It is a good project as it makes it a better lathe with less chatter and less tool flex.

No, it is steel. ( I just polish everything.). If I clamp something to the table, I try to set it up to do the milling horizontally. I set the height of a part by using spacer blocks or shim under it to get the height. I usually bolt my vise flat on the table, but can bolt it to a small angle plate and bolt that to the table. Yes , you are limited to one axis for milling. I had started to make a slide that would bolt on and give vertical as well as horizontal milling, but since I bought a mill , I don't need to finish it right now. With a little ingenuity, you can mill almost anything that will fit on the table. The one odd hole in the table is to lock it from turning. The anchor is solid, it can't. Come off.

My thoughts on a milling attachment.
I think they have a place. Some people can't afford a milling machine or just don't have the space. They are limited but better than nothing. I bought one years ago and it worked fine for a few small projects. If you're going to get one, get the Southbend. They hold their value. You can buy one today, use it till you get a mill then sell it for what you paid or more. When you buy a mill, get a Clausing,or equivalent. Don't buy something cheap. I've had a Clausing for years along with 2 Bridgeports and still use the Clausing. I still have my Southbend milling attachment and might be interested in selling it. Email me if you want some info.

Milling attachments CAN do good work if you baby them along. I had one for my first lathe for some time before I found a small milling machine.

They ARE good for CERTAIN things,even if you have a mill. My friend uses one for milling out the area that the ejector fits in on the end of rifle barrels. To do this on his Bridgeport,he'd have to tilt the head 90º,and re tram it when done. The lathe attachment is quicker.
