    vacuum for use on a lathe

    I made a 20 gallon grease drum into a centrifuge in the center of my shop and have a 5 gallon Sears vac (30 yrs old) outside with my suction line under the floor to the centrifuge. I pick up all chips, lathe and mill. I have a coffee can of wood blocks and when picking up string chips, throw...

    Rotary Table Alignment

    Discussing vises is a good way to start arguments I have had a 5 inch Kurt in my shop for 43 years and it is as close to perfect as they come. I was given a 4 inch Kurt imitation made in India and it was a piece of garbage. Took about 30 hours of rework to get it square and flat. I would say 60...

    Rotary Table Alignment

    You do not need a centerdrill. Centerdrills are for making centers in a shaft in order to use a live or dead center, but it's "convenient" for some to use for drilling, but sometimes even centerdrills are off . Also they are 60 degrees and not 118 like a drill. Do what machinists have done for...

    Rotary Table Alignment

    Why would you want to do 3 and 12? Speed , is the essence of working on setups. Setups do not pay bills, so in most all machine shops , it's the tricks of the trade that can make a job profitable or not. Fixing Nod is a pain in the butt for most machinists, as evidenced by your purchase of a...

    Trouble with cut off operations

    Peter, the point I was making was keeping the cutting load centered on the support provided by the cross-slide AND tool-slide areas. Removing the tool-slide function as shown in your pics is also a great help as it removes another "Flex" joint in the assembly . No doubt a lathe without a...

    Trouble with cut off operations

    The main reason a rear Toolpost functions well is that the load is supported "within " the cross-slide ways. This is important for newbies to understand Rich

    Trouble with cut off operations

    One thing I do not see here is how to set your tool height ! If you do not have a 6" aluminum scale, get one. Steel scales work ,but tend to be slippery when used and drop into the chip tray This works for any Lathe Tool Place the scale between the workpiece and the toolbit and gently bring the...

    Trouble with cut off operations

    Tornitore45 has it right ! You can use a tailstock or steady rest for help in parting-- but not through ! How much so--- is dependent on the rigidity of the Lathe ---and the Live Center !! If you push on the workpiece and you can move it......beware ! The more "flexible" the workpiece , the...

    Fixing an old lathe with spindle "droop"

    Late to the party here, But always looking for simple fixes. Are both the bearing inserts (front and rear) the same ? Can you reverse them ? On the front bearing , can you flip it bottom to top ? By moving the bearings around you may solve the drop . On a side note, try to stay with Tin or Tin...

    Parting made easy

    Goldstar It's a Boxford Lathe ( Which is the British Version of the Southbend...but Greatly improved !) I rebuilt mine (scraped the ways) and it is a bit different. The "Legs" of the carriage were ground parallel to the cross-slide ways, so when (but I never did) I put a Boring table on the...
