    looking for a onestep drilling option on a lathe

    thanks for the replies. youre correct about the swapping out in a drill chuck, it works, but takes too long to do a couple of hundred. im going to try a carbide tipped flute drill. i have a tendency to shatter full carbide drills, pretty sure its operator error

    looking for a onestep drilling option on a lathe

    ahem, with regards to the machine, lets just say its small, chinese and against the rules to mention. maybe spotting drill isnt the right name, cantering drill? the bit used to make the hole so you can turn between centers.

    TIG welding 1mm stainless to 6mm stainless-is this possible?

    dc pulse has frequency settings. you can also control heat with the filler rod, if you keep the rod jammed in the joint puddle and get the torch angle right it flows together beautifully. i used to weld exhaust bellows which was usually welding .032" to 1/4", once you get the hang of it its no...

    What are these grinding wheels for?

    also called blending discs. theyre not too agressive and leave a smoother finish than hard resin discs. they last longer than flap discs and arent as flexible which is sometimes handy, sometime not.
