    Trying to align an old Lathe

    I've used a similar technique for making long lengths of threaded bar. It works very well for smaller diameters and finer threads like M6, 3/16 W and BA. Smallest I've done has been 8BA and the biggest M6. Though because of the difficulty I've experienced in grinding threading bits, I've...

    Trying to align an old Lathe

    Hi Guys, Actually it doesn't matter at all. If you angle the top slide you can easily take a fraction of a thou off your work without even moving the cross slide. I forget what the angle is to set it to, something like 5.5 degrees, then each division becomes a tenth. About the only time I...

    Trying to align an old Lathe

    Hi Guys, Agreed ! There isn't too much that you can do about bed twist on an ML4. In theory as long as the lathe hasn't been abused or damaged, the bed should be as straight as it was when it left the factory. Any adjustment is now down to shims. But based on your gauge readings it is...

    Jon, That flywheel looks fantastic ! You should give yourself a pat on the back for that one.

    Cutter grinder

    Hi Norman, Thankyou for the offer ! Yes a small fractional HP motor would be ideal. I'm thinking of trying to mount the motor and spindle in a similar way to the Quorn. The mounting pillar is only 20 mm diameter so I'm trying to balance the weight roughly equal on both sides of the column...

    Cutter grinder

    Hi Guys, I'm in the throws of making my version of a "Brooks TCG". I've almost finished the grinding spindle cartridge, but still have a lot to do, including finding a suitable motor to drive the spindle. The part finished grinding spindle.

    Trying to align an old Lathe

    This is an "Elephants Foot" ! It screws into the dial gauge stylus in place of the ball end. Just to give you an idea of size, that is resting on the top of a jaw on a 100 mm three jaw lathe chuck.

    Laser cut gaskets

    Teflon will cold flow under pressure, which is one reason it makes good head gaskets. Actually I could use about half a dozen 5 thou Teflon washers for a project that I'm building. I need 21 mm diameter ones with a 19 mm hole, for use as preload for the bearings I'm using. I haven't decided...

    Rocker Style vs. QCTP

    Now come on Guys, doesn't the pictures of the toolpost and the adjusting screw make it obvious ! This is a picture of the tool post being tried on the existing bolt. The three cap head screws and the ratchet were removed before fitting. I could have left them but in the interests of getting...

    Rocker Style vs. QCTP

    Hi Danuzzo, The height adjustment is the silver colored cap screw that runs vertically through the tool block and presses on the surface below. This allows the tool block to be raised or lowered as needed. This is also why I mentioned that the tool slot in the block needs to be machined so...

    Rocker Style vs. QCTP

    Hi Richard, I'm a cheapskate :cool: I raid my local scrap yard ! However it helps that I've known the family owners for many many years and they do put stuff on one side for me. There are some metal suppliers around the area but they tend not to be cheap, especially if you want something...

    Rocker Style vs. QCTP

    Hi Danuzzo, Note that the tool block was actually a piece of 1" inch thick rolled steel plate that I picked up in the scrap yard I cut it up into three suitable sized pieces. The column, 35 mm diameter in the drawing was a chunk of 40 mm bar, again picked up as scrap. It was originally about...

    Rocker Style vs. QCTP

    Hi Guys, This is my drawing ! If you use this check the dimensions carefully, its a while since I made one and I don't remember if I altered the split cotter size from 12 mm to 14 mm. It sticks in my mind that the original bolt through the split cotter was M5 and I changed it to M6 so that...

    Rocker Style vs. QCTP

    Hi Danuzzo, A Norman Patent tool post would go on there perfectly ! You would have to make a proper "T" nut base though, but the rest is quite straightforward.
