    hi all
    i want to drill and tap two holes in the end of the carriage
    what would be the best way to do this.

    i guess trying to drill them with the carriage on the lathe with a power drill would be hard.

    so really the best way i can think of
    would be to take the carriage off and drill on a pillar drill.....?

    and I don't have a mag drill.... unless someone close to me does.



    thoughts....

    cheers all

    If i had to do it i would just make a drilling jig, located and secured on the two tapped holes that secure the handwheel leadscrew assembly.something nice and flat(obviously) with a couple of decent size holes on your required pitch then make two sleeves a good push fit into your base, make sleeves also for your tapping drill and your tap.

    I have an M10 stainless repair washer with one side ground flat and mirror polished, if the drill bit in the reflection looks like it's in a straight line with the actual bit then the bit is perpendicular to the mirror surface.
    I superglue the washer centered on the punch mark and have at it with a battery drill, keeping the bit and it's reflection aligned,

    mekanik that's a good idea and worth a try.
    though i don't know how hard its going to be to drill it
    il take some measurements for making the jig.
    cheers.

    When you make the sleeve for the jig plate have a reasonable size flange butting up to the plate and push it in with your vice this will make sure it's square.
    I have something in the shed if i can find it, i will try and upload a picture.
    Regards
