Atlas Lathe feed screw clutch adjustment
I have a 12" Atlas Lathe with the slip clutch on the feed screw. The
slip on the clutch is adjusted by turning a round sleeve with a spanner hole in it. Is there a tool made to perform this adjustment? Anybody knows who sells this tool? To date, I've been using Vicegrip pliers to tighten the clutch, which is taking its toll. I'd very much like to adjust the slippage by using the proper method. Thanks in advance for any suggestions.

Go to http://www.mcmaster.com and search for "spanner wrenches". Scroll
down the page a bit and see if that's what you're looking for. Best Regards, Keith Marshall "I'm not grown up enough to be so old!" wrote in message oups.com...

Clausing may sell one. They merged with Atlas quite a few years ago and
still have many spare parts. Ask for Jolene Olds if you call. http://www.clausing-industrial.com/service-std.htm Mike wrote in message oups.com...

Go to http://groups.yahoo.com/group/atlas_...guid=122382924 This is a Yahoo group for your lathe. You will have to register and Join This Group, but it's painless and free. Then go to the Files section, and find Atlas QC Gearbox.pdf. it's a 1700 KB download that shows how to change from change gears to a QC box. On page 3 are detailed instructions for adjusting that clutch. hope that helps. -- - - Rex Burkheimer WM Automotive Fort Worth TX |

Many thanks for that lead....
I just spoke with Jolene and all that she had available were the same instructions that I have for the lathe. That is, to use a 1/8" rod in the adjustment hole to torque the proper tension. This simply does not do the job. No special tool from Clausing is available for the purpose. That failing, I'm just going to have to mic the diameter of a adjustment sleeve and see if I can find someone offering a spanner of the appropriate diameter with a 1/8" pin. Perhaps I'm a perfectionist, but it seriously troubles me to use something like Vicegip pliets on so fine a piece of metalworking machinery, as I'd like to leave the machine in the same or better condition than I received it.

You have a lathe, so build one. Turn a thickwall tube ring with an ID equal to the OD of the clutch sleeve Drill a 1/8" radial hole centered 3/16" from the edge (optional) Drill a 2nd hole about 70 degrees away for the handle. Part it off at 1/4 Remove the larger part of the ring adjacent to your two holes. Insert a pin in one hole, handle in the other. Weld, braze or silver solder. If you don't have a welder, you will have to engineer a solid attachment for the handle Final dimensions will probably vary, but that's the general idea -- - - Rex Burkheimer Fort Worth TX |
