Glenn provided the following description: ================================================================= These pictures, starting with atlmod1.jpg through atlmodb.jpg are of mods I have done to my 6" Atlas lathe. atlmod1.jpg is an overall view of the lathe showing the variable speed motor and the handy holder for gears etc. it did not come out very clear for some reason but is ok for the general idea. Everything is mounted on a 1/2" steel plate and you can see I used the powertwist belts. Those really smoothed out things quite a bit. atlmod2.jpg is a close up of the stainless steel box I mounted the treadmill motor speed control and switches in. atlmod3.jpg is an end view of the motor. I was trying to show the airconditioner filter material as applied to the motor. atlmod4.jpg is an as used picture of the milling attachement I built using a block of aluminum, a dovetail slide and a palmgren drillpress vise. It is by no means a milling machine but it will allow you to make things like toolpost blocks and cut keyways etc. The endmill is held in a holder I built that seems to do a very good job. atlmod5.jpg is a bottom view of the milling attachment showing the hole I bored on the lathe and the mounting screws that push the three dowel pins into the compound mounting boss. I could have used a lot less aluminum but I don't see much advantave to cutting off the excess. I could have also use a piece of angle but I had the block and I think it is probably more ridgid. atlmod6.jpg is a close up of the endmill holder. Note the "extra" hole. I put a pin in the hole and use a spanner to remove the holder from the spindle. atlmod7.jpg is a view of the threads and register area of the endmill holder. I made the threads and register first, then I installed it on the spindle and turned the outside to this shape and bored the hole for 1/2", 3/8" and 5/16" endmills (made three holders) atlmod8.jpg is the toolblock I made with the milling attachment holding a 1/2" indexable carbide toolbit. The other side has a holder for a parting tool. I have another toolblock that holds 3/8" bits and a boring bar. atlmod9.jpg shows the parting tool side of the toolblock. Note that I milled the slot for a 1/2" parting tool and milled a slot at the top of the slot to let the parting tool sit square. I used flathead sockethead screws to push in and down on the tool. I get supprising results with this setup (third try at a parting tool holder and first one that really works) atlmoda.jpg shows the spindle wrench on the spindle. I drilled a hole for a removeable pin to hook the spanner on. Now I don't have to put stress on the back geats to get the chuck or endmill holders off. atlmodb.jpg is a view of the motor mounting, belts, and speed controller. I also switched this lathe over from bronze bushings to timken roller bearings by replacing the headstock and making a new spindle that fit everything. I am not too crazy about the switches being behind the headstock or the gear tray being behind the lathe as one could be tempted to reach over spinning metal etc. I reach the switches from the side most of the time and use a great deal of caution but I do intend to remote the on/off switch to the front of the lathe. Or put a "kill" button someplace I can get to without getting close to the lathe. As is I can always unplug it :) Thanks for all the help getting these things accomplished!! I sure couldn't have done it with out your support and great ideas. Glenn Neff Medford, OR
