    How to create a female taper thread?

    Hi Select the proper drill and crank the NPTsp in until the plug for the same taped hole goes in to the right depth. I do know the bigger pipe taps do better with a tapered hole drill. Dennis

    Variable speed control for a small lathe

    A VFD is a good way to go. Any three phase motor can work. If the motor is rated for electronic controls it will work much better. If not the motor can be noisy. Do the research and pick the pulley sizes for the range you really need. better a little on the slower top speed. Remember the chucks...

    Problems with face cutting on lathe, wavy pattern

    Hi You might look at how close the tool tip is to the hold down bolt. Closer is better. Less leverage. I have seen this type of tool flexibility in my 9 x 20 enco. The tool geometry will have an effect too. If it digs in and tips toward the work you will get odd finishes. These small lathes are...

    AL51G belt running off

    Hi I have an enco 9 x 20 lathe. It uses the 5mm 710 and 730mm belts. I think they are too small for the loads. If the pulleys and tensioner are in line you will not have any trouble with the belts staying on, most of the time. I find in some grooves/ ratios the belt will be very loose, The 710...

    here are a few of my ( maybe ) stupid questions

    Hi I don't think any one mentioned overheating. If the parts are over heated the solder won't flow and stick. I used to watch my Dad do solder pipe joints and the finish was a wipe down with a damp rag. I have seen small jobs wiped with w wet brush, same idea. The fix for an over heated joint...

    Tapping Question

    I bought a tapping fixture a number of years ago and discovered the big factor in tapping small threads. The big factor is alignment with the hole to be tapped. The second is the hole size along with the hole diameter. Going for a 75% thread is very sensible especially in a model where the loads...

    Mini Lathe Tips

    Hi I have learned the achievable accuracy is mostly in the operator, This is how a good machinist is able to turn out good work on old worn out machines. I found alignment issues in my Mini(7 x 12 lathe ) which I was able to correct. Once your machine is in alignment (the axis of the spindle in...
