Hoist over lathe for changing chucks

admin

I have an old Leblond lathe that uses screw on chucks. Before I moved the lathe a year ago I had a hoist for changing the chucks. With no hoist in the new location, I've been man handling the chucks on and off. About a month ago I squished my pinkie finger while changing the chuck, it required 4 stitches and I'm lucky to still have all my fingers. Today I finished re-installing the hoist. I had to adapt the design to the new location which required some new bracket.Picture 1: Cut the parts on the plasma table. I designed the parts in Alibre Design.Picture 2: Bending the ears on the press brake.Picture 3: Finished parts ready to be installed.Picture 4: With the new trolley installed. Attached Images

Reply:I also installed a new chain hoist because the old hoist and trolley are now being used on the gantry. Not sure why the chain hoists don't come with chain buckets so I whipped one up. This hoist uses small chain so the bucket is small. I'm sure I voided the warranty when I disassemble the hoist to install the bucket. I assumed the bolt would slide out... no such luck. Next time I'll design the bucket to hang from a hook. Experience is the best teacher.I also include the chuck leveler/spinner I built a few years back (one of my first welding projects). I mounted a couple of bearings for the chuck to grip that allow the chuck to spin on and off. I also include a level adjustment because the center of gravity of ever chuck is a little different.Picture 1: Welded on the bucket eye.Picture 2: Disassembled the hoist to install the bucket.Picture 3: Hoist re-assembled.Picture 4: Chuck leveler.

Reply:that happnd' to me once too...... even though it feels HEAVY spinnig off , u think your prepared, your still just not holding Up on it enough once it releases off of the last thread and takes one of your fingers or knuckles  on the ways.  I've got a 3 Jaw , 4 Jaw and a FacePlate..........faceplates not so bad.cool little trolley , hoist  and chuk holdr'Last edited by woi2ld; 03-16-2010 at 12:19 AM.        thermal arc 252i  -  millermatic 350P -   miller XMT, cp300ts, 30a 22a feeders, buttload of other millers, handfull of lincolns, couple of esabs  -   Hypertherm 1250 G3
Reply:I have to agree. I like the brackets you made and especaiily the adjustable chuck holder.I just wish I had room for a CNC plasma at my place... It makes some things so simple..No government ever voluntarily reduces itself in size. Government programs, once launched, never disappear.

Reply:I LIKE IT, well done and I see you even have the chuck closed on a bearing for screwing it on. You thought of everything.
Reply:Is it a software limitation that you didn't use a common edge on your two cnc'd cutouts?

Reply:Did the sheetmetal module of Alibre write the G-code?  How did you go from Alibre to the cnc plasma?  I am real curious about this.  Thanks.

Reply:Well thought out and designed, good jobI always tried to work with the oldest hand on the job to gain knowlege but now I can't find any.
Reply:The work looks good but, Just curious why you did this?I always used an engine hoist with an eye bolt.
Reply:I think it's an awesome design and idea. A wooden chuck block is also great too. My little 3x lathe chucks only require fingers to remove ha.
