Just bought a Atlas 618 with se many extras can’t wait to find how to use them
I am looking for a quick change tool post for my Atlas 618 any suggestions would be appreciated
The wedge type are more repeatable in how they hold the toolholder. With the wedge the forces are pushing against the 2 dovetails and through the dovetail angle, cause the holder to both be positively located against the stationary dovetail, and pulled in against the face of the tool post. With the piston type, it pushes the toolholder out against the dovetails, so there is no positive stop, the harder you clamp the more it "could" move out. Also possible for a little bit of play in exactly where it lines up as you clamp. May be that this is splitting hairs, but the wedge type is where its at for repeatability.
Is there anyone in Thunder Bay that can give me advise with my 618 Atlas
It can with all the toolsDid you get a copy of the book that came with it? "Manual of Lathe Operations", often referred to as 'MOLO'. If not, you can get a digital copy from the Vintage Machinery web site:
Or look on Youtube. Mr. Pete did a series on refurbishing a 618 recently. Etc.

(If you got all that for $300, you got a screaming deal. The milling attachment is relatively rare and some people will pay a lot just for that.)
