I'm looking for a milling attachement for my Atlas 10F lathe. I know I
know I'd be better off buying a milling machine but space and $ are the
main reasons I'm looking for the attachment. Anybody that has one
collecting dust please drop me a note at email@example.com

One of the guys from MDMC brought in a show-and-tell last year. He
made one up from a 3" cast steel 90 degree pipe elbow and two end
plugs, some plate, and some welding (brazing). He made a piece up
like the male spigot on the bottom of the compound slide and brazed
that onto one plug on the elbow. This would eventually be put into
the place on the cross-slide that the compound goes now. Then he made
a plate with a copy of the "hole" the same as the top of the
cross-slide including two set-screws, and brazed that onto the other
end of the elbow. so now, he had created a "90 degree extension" to
mount the compound on. He got an el-cheapo vice and fastened it on
the now vertical compound in place of a tool-holder.
So, now you can rotate the whole mess, just as you could the compound,
plus you can rotate the now vertical compound, plus still move both
the carriage and the cross-slide AND the compound too. Pretty neat
Gee, I wonder who I know with a lathe and that might have connections
with a factory supplier like Westburne that might have an elbow, and a
cheap vise. Hmm .... I'll have to think about that for a bit. Lemme
know if you can think of anybody, will you?
Read what I wrote again. It's only one pipe elbow, and you DO use
the compound!! Although they are adjustable, most milling attachments
are used with the compound mounted to move in the dead vertical
position. That allows you to make "sharp corners" with a milling
cutter running in the head-stock.
Cross-feed does the "X" axis, the compound does the "Y" axis, and the
carriage does the "Z" axis, or depth of cut. But with the compound
"adjustable", you can set it to cut along an angle that is not 90
degrees if you want. That's hard to do with a standard milling
machine, and would usually require a rotary table.
I have a Palmgren tilting rotary table with x and y axis movement that
I use on the mill. I think it would make a better milling attatchment
for the lathe. When in use on the mill the x and y movement is
oops typo on my part. I think I get the general idea. You place the
elbow where the compound usually mounts. With I guess a plug in the end
that allows the angle bit on the cross feed to go inside it and then the
regular wedge pins and screws to hold it down.
Then on the other end of the elbow you mount the compound rest. You'd
have to have a similar wedge shaped protrusion here that you have on the
cross feed. Mount a vise where the toolpost goes and just like magic you
got a milling attachment the also swivels.
Do I have it clear in my foggy mind now?
Yep! It may be me, but on my lathe there is a "hole" in the
cross-slide, and a boss on the compound. Maybe your lathe is the
opposite. But the idea is the same.
